Regulating HFT in India

The Securities and Exchange Board of India (SEBI) has set a cat among the HFT (High Frequency Trading) pigeons by proposing seven measures to curb the impact of HFT and improve “real liquidity” in the stock markets.

The big problem with HFT is that algorithms tend to cancel lots of orders – there might be a signal to place an order, and even before the market has digested that order, the order might get cancelled. This results in an illusion of liquidity, while the constant placing and removal of liquidity fucks with the minds of the other algorithms and market participants.

There has been a fair amount of research worldwide, and SEBI seems to have drawn from all of them to propose as many as seven measures – a minimum resting time between HFT orders, matching orders through frequent batch auctions rather than through the order book, introducing random delays (IEX style) for orders, randomising the order queue periodically, capping order-to-trade ratio, creating separate queues for orders from co-located servers (used by HFT algorithms) and review provision of the tick-by-tick data feed.

While the proposal seems sound and well researched (in fact, too well researched, picking up just about any proposal to regulate stock markets), the problem is that there are so many proposals, which are all pairwise mutually incompatible.

As the inimitable Matt Levine commented,

If you run batch auctions and introduce random delays and reshuffle the queue constantly, you are basically replacing your matching engine with a randomizer. You might as well just hold a lottery for who gets which stocks, instead of a market.

My opinion this is that SEBI shouldn’t mandate how each exchange should match its orders. Instead, SEBI should simply enable individual exchanges to regulate the markets in a way they see fit. So in my opinion, it is possible that all the above proposals go through (though I’m personally uncomfortable with some of them such as queue randomisation), but rather than mandating exchanges pick all of them, SEBI simply allows them to use zero or more of them.

This way, different stock exchanges in India can pick and choose their favoured form of regulation, and the market (and market participants) can decide which form of regulation they prefer. So you might have the Bombay Stock Exchange (BSE) going with order randomisation, while the National Stock Exchange (NSE) might use batch auctions. And individual participants might migrate to the platform of their choice.

The problem with this, of course, is that there are only two stock exchanges of note in India, and it is unclear if the depth in the Indian equities market will permit too many more. This might lead to limited competition between bad methods (the worst case scenario), leading to horrible market inefficiencies and the scaremongers’ pet threat of trading shifting to exchanges in Singapore or Dubai actually coming true!

The other problem with different exchanges having different mechanisms is that large institutions and banks might find it difficult to build systems that can trade accurately on all exchanges, and arbitrage opportunities across exchanges might exist for longer than they do now, leading to market inefficiency.

Then again, it’s interesting to see how a “let exchanges do what they want” approach might work. In the United States, there is a new exchange called the Intercontinental Exchange (IEX) that places “speed bumps” over incoming orders, thus reducing the advantage of HFTs. IEX started only recently, after major objections from incumbents who alleged they were making markets less fair.

With IEX having started, however, other exchanges are responding in their own ways to make the markets “fairer” to investors. NASDAQ, which had vehemently opposed IEX’s application, has now filed a proposal to reward orders by investors who wait for at least once second before cancelling them.

Surely, large institutions won’t like it if this proposal goes through, but this gives you a flavour of what competition can do! We’ll have to wait and see what SEBI does now.

The problem with venture capital investments 

Recently I read this book called Chaos Monkeys which is about a former Goldman Sachs guy who first worked for a startup, then started up himself, sold his startup and worked for Facebook for a number of years. 

It’s a fast racy read (I finished the 500 page book in a week) full of gossip, though now I remember little of the gossip. The book is also peppered with facts and wisdom about the venture capital and startup industries and that’s what this blogpost is about. 

One of the interesting points mentioned in the book is that venture capitalists do not churn their money. So for example if they’ve raised a round of money, some of which they’ve invested, liquidating some of the investment doesn’t mean that they’ll redeploy these funds.

While the reason for this lack of churn is not known, one of the consequences is that the internal rate of return (IRR) of the investment doesn’t matter as much as the absolute returns they make on the investment during the course of the round. So they’d rather let an investment return them 50x in 8 years (IRR of 63%) rather than cash it one year in for a 10x return (IRR of 900%). 

Some of this non churn is driven by lack of opportunities for further investment (it’s an illiquid market) and also because of venture capitalists’ views on the optimal period of investment (roughly matching the tenure of the rounds). 

This got me thinking about why venture capitalists raise money in rounds, rather than allowing investors continuous entry and exit like hedge funds do. And the answer again is quite simple – it is rather straightforward for a hedge fund to mark their investments to market on a regular basis. Most hedge fund investment happens in instruments where price discovery happens at least once in a few days, which allows this mark to market. 

Venture capital investments however are in instruments that trade much more rarely – like once every few months if the investor is lucky. Also, there are different “series” of preferred stock, which makes the market further less liquid. And this makes it impossible for them to mark to market even once a month, or once a quarter. Hence continuous investment and redemption is not an option! Hence they raise and deploy their capital in rounds. 

So, coming back, venture capitalists like to invest for a duration similar to that of the fund they’ve raised, and they don’t churn their money, and so their preferences in terms of investment should be looked at from this angle. 

They want to invest in companies that have a great chance of producing a spectacular return in the time period that runs parallel to their round. This means long term growth wise steady businesses are out of the picture. As are small opportunities which may return great returns over a short period of time.

And with most venture capitalists raising money for similar tenures (it not, that market fragments and becomes illiquid), and with tenure of round dictating investment philosophy, is there any surprise that all venture capitalists think alike? 

Banks starting to eat FinTech’s lunch?

I’ve long maintained that the “winner” in the “battle” for payments will be the conventional banking system, rather than one of the new “wallet” or “payment service providers”. This view is driven by the advances being made by the National Payments Corporation of India (NPCI) which is owned by a consortium of banks.

First there was the Immediate Payment System (IMPS) which allows you to make instant inter-bank transfers. While technology is great, evangelism and product management on the banks’ part has been lacking, thanks to which it has failed to take off. In the meantime NPCI has come up with an even superior protocol called Universal Payment Interface (UPI), which should launch commercially later this year.

There is hope that banks do a better job of managing this (there are positive signs of that), and if they do that, a lot of the payment systems providers might have to either partner with banks (the BookMyShow wallet is already powered by RBL (the artist formerly known as Ratnakar Bank Limited) ).

In the meantime, banks have started encroaching on FinTech territory elsewhere. One of the big promises of FinTech (and one I’ve participated in, consulting with two companies in the space) has been to ease the loans process, by cutting through the tedious procedures banks have to offer, and making it a much more hassle-free process for borrowers.

A risk in this business, of course, has been that if banks set their eye on this business, they can eat up the upstarts by doing the same thing cheaper – banks, after all, have access to far cheaper capital, and what is required is a procedural overhaul. The promise in the FinTech business is that banks are large slow-moving creatures, and it will take time for them to change their processes.

Two recent pieces of news, however, suggest that large banks may be coming at FinTech far sooner than we expected. And both these pieces of news have to do with India’s largest lender State Bank of India (SBI).

One popular method for FinTech to grow has been to finance sellers on e-commerce platforms, using non-traditional data such as rating on the platforms, sales through the platform, etc. And SBI entered this in January this year, forming a partnership with Snapdeal (one of India’s largest e-commerce stores).

Snapdeal, India’s largest online marketplace, today announced an exclusive partnership with State Bank of India to further strengthen its ecosystem for its sellers. With this association, Snapdeal sellers will be able to get approval on loans from financers solely on the basis of a unique credit scoring model. There will be no requirement of any financial statements and collaterals.

Sellers on the marketplace can apply for loans online and get immediate sanction, thereby enabling “loans at the click of a button”. This innovative product moves away from traditional lending based on financial statements like balance sheet and income tax returns. Instead, it uses proprietary platform data and surrogate information from public domain to assess the seller’s credit worthiness for sanctioning of loan.

Another popular method to expand FinTech has been to lend to customers of e-commerce stores. And in a newly announced partnership, SBI is there again, this time financing purchases on the Flipkart platform.

State Bank of India, the country’s largest bank, announced a series of digital initiatives on Friday, including a first of its kind partnership with e-commerce giant Flipkart, to offer bank customers a pre-approved EMI facility to purchase products on the retailer’s website.

The bank, which celebrates its 61st anniversary (State Bank Day) on July 1, said the objective was to provide finance to credit worthy individuals, and not just credit card holders. The EMI facility will be available in tenures of six, nine and 12 months.

Just last evening, I was telling someone that there’s no hurry to get into FinTech since it will take a decade for the industry to mature, so it’s not a problem if one enters late. However, looking at the above moves by SBI, it seems the banks are coming faster!

 

Liquidity and the Trump Trade

The United States Treasury department has floated a new idea to improve liquidity in the market for treasury bonds, which has been a concern ever since the Volcker Rule came into place.

The basic problem with liquidity in the bond market is that there are a large number of similar instruments trading, which leads to a fragmented market. This is a consequence of the issuer (the US Treasury in this case) issuing a new bond every time they wish to borrow more money, and with durations being long, many bonds are in the market at the same time.

The proposed solution, which commentators have dubbed the “Trump Trade” (thanks to the Republican Presidential candidate’s penchant for restructuring debt of his companies), involves the treasury buying back bonds before they have run their full course. These bonds bought back will be paid for by newly issued 10-year bonds.

The idea here is that periodic retirement of old illiquid bonds and their replacement by a new “consolidated” bond can help aggregate the market and boost liquidity. This is not all. As the FT ($) reports,

The US Treasury would then buy older, less liquid and therefore cheaper debt across the market, which could in theory then be reissued at a lower yield. In recent months, yields on older issues have risen more than those for recently sold debt, suggesting a deterioration in liquidity.

This implies that because these “off the run” treasuries are less liquid, they are necessarily cheaper, and this “Trump Trade” is thus a win. This, however, is not necessarily the case. Illiquidity need not always imply lower price – it is more likely that it leads to wider spreads.

Trading an illiquid instrument implies that you need to pay a higher transaction cost. The “illiquidity discount” that many bonds see is because people are loathe to holding them (given the transaction cost), and thus less people are willing to buy them.

When the treasury wants to buy back such instruments, however, it is suddenly a seller’s market – since a large number of bonds need to be bought back to take it off the market, sellers can command a higher spread over the “mid price”.

Matt Levine of Bloomberg View has a nice take on the “IPO pop” which I’ve written about on this blog several times (here, here, here and here). He sees it as the “market impact cost” of trying to sell a large number of securities on the market at a particular instant.

Instead the typical trade of selling, say, $1 million of a bond with $1 billion outstanding, and paying around 0.3 percent ($3,000) for liquidity, you want to sell, say, $1 billion worth of a bond with zero bonds outstanding. That is: You want to issue a brand-new bond, and sell all of it in one day. What sort of bid-ask spread should you pay? First principles would tell you that if selling a few bonds from a large bond issue costs 0.3 percent, then selling 100 or 1,000 times as many bonds — especially brand-new bonds — should cost … I mean, not 100 or maybe even 10 times as much, but more, anyway. No?

Taking an off-the-run bond off the market is reverse of this trade – instead of selling, you are buying a large number of bonds at the same time. And that results in a market impact cost, and you need to pay a significant bid-ask spread. So rather than buying the illiquid bond for cheap, the US Treasury will actually have to pay a premium to retire such bonds.

In other words, the Trump Trade is unlikely to really work out too well – the transaction costs of the scheme are going to defeat it. Instead, I second John Cochrane’s idea of issuing perpetual bonds and then buying them back periodically.

These securities pay $1 coupon forever. Buy these back, not on a regular schedule, but when (!) the day of surpluses comes that the government wants to pay down the debt. Then there is one issue, with market depth in the trillions, and the whole on the run vs. off the run phenomenon disappears.

People don’t worry enough about liquidity when they are trying to solve other liquidity worries, it seems!

 

Big data at HDFC Bank?

I had a bit of a creepy moment today – I must admit that, despite being a “data guy” and recommending clients to use data to make superior decisions (including customisations), it does appear creepy when you as a customer figure that your service provider has used data to customise your experience.

I’m in Barcelona, and wanted to withdraw cash from my Citibank account in India. Withdrew once, but when I wanted to withdraw more, the transaction didn’t go through (this happened multiple times, at multiple ATMs).

Frustrated, I figured that this might be due to some limits (on how much I could transact per day), and then decided to get around the limitations by transferring some money to my HDFC Bank account (since I’m carrying that debit card as well).

An hour after I’d transferred the money by IMPS, I put my HDFC Debit Card in my wallet and walk out, when I see an email from the bank informing me that my Debit Card is valid only in India, and with a link through which I could activate international transactions on it.

I’d never received such emails from HDFC Bank before, so this was surely in the “creepy” category. It might have been sent to me by the bank at “random”, but the odds of that are extremely low. So how did the bank anticipate that I might want to use my debit card here, and send me this email?

I have one possible explanation, and if this is indeed the case, I would be very very impressed with HDFC Bank. Apart from my debit card, I also have a credit card from HDFC Bank, which I’ve been using fairly regularly during my time in Europe (that my only other credit card is an AmEx, which is hardly accepted in Europe, makes this inevitable).

My last transaction on this credit card was to pay for lunch today, and so if HDFC Bank is tracking my transactions there, it knows that I’m currently in Europe (given the large number of EUR transactions recently, if not anything else).

Maybe the bank figured out that if I’m abroad, and have transferred money by IMPS (which implies urgency) into my account, then it is for the purpose of using my debit card here? And hence they sent me the email?

The counterargument to this is that this is not the first time I’ve IMPSd to my HDFC Bank account during this trip – the Income Tax and Service Tax websites don’t accept Citibank, so I routinely transfer to HDFC to make my tax payments. So my argument is not watertight.

Yet, if the above explanation as to why HDFC Bank guessed I was going to use my debit card is true, then there are several things that HDFC Bank has got right:

  1. Linkage between my bank account and credit card. While I’ve associated both with the same customer ID, my experience with legacy systems in Indian financial institutions means actually associating them is really impressive
  2. Tracking of my transactions on my credit card to know my whereabouts. If HDFC has done a diligent job of this, they know where exactly I’ve been over the last few months (provided I’ve used my card in these destinations of course).
  3. Understanding why I use my account. While I’ve IMPSd several times in the past (as explained above), it’s all been in either the “service tax season” or “advance/self-assessment income tax season”. Mid-May is neither. So maybe HDFC Bank is guessing that this time it may not be for tax reasons?
  4. Recognising I might want to use my debit card. If I’ve put money into my account and it’s not tax season, maybe they recognised I might want to use my debit card?

Maybe I might be giving them too much credit, and it just happened that the randomly sent out email came at the time when I’d just put the money into the account.

And the link they sent to enable international transactions worked! I had to use my laptop (it didn’t work on either the app or mobile web, so that’s one point deducted for them), but with a few clicks after logging into my bank account, I was able to enable the transactions!

So maybe there is reason to be impressed!

 

Private and public valuations

HSBC seems to have set a cat among the private market pigeons by recommending that Zomato’s “real valuation” is half of the stated headline valuation (my apologies for not “covering” Zomato in my piece on startup valuations two weeks back).

This was part of HSBC’s analyst report on InfoEdge (Naukri), which is Zomato’s largest investor. All possible parties concerned have hit back at HSBC for this valuation. Most of them (Sanjiv Bikhchandani (founder of InfoEdge), Zomato founder Deepinder Goyal, investor Sequoia, etc.) have been simply talking their book.

But you see several completely unrelated people in the Indian startup world commenting about HSBC’s valuation, including allegations that HSBC doesn’t understand how private companies are to be valued.

The interesting thing about this discussion is that you seldom see such debates about public companies. Nobody questions analyst reports of public companies on methodology. At worst, company PRs might issue statements challenging some of the assumptions that have gone into the analyst reports.

What differentiates public and private market analyst reports is the ability to trade – if you have a view on the valuation of a public company, it is rather easy for you to turn this view into a profit (with the risk of a loss) by trading on it. If you think a company is undervalued, you buy shares, and profit when its valuation corrects.

With private companies such as Zomato, on the other hand, there is no way for someone who is not already an investor to profit from their views on the company’s valuation. Shorting is out of the question. Even going long happens in different “series”, and is not a continuous process.

If Zomato were a public company, investors acting on HSBC’s report might have tried to push down the price of the stock, and the extent of money on the “other side” would have quickly shown whether HSBC’s view was correct. With the company being private, such objective means of agreeing on valuations don’t exist. And so concerned parties bicker.

To me, the most telling line in the Mint report on the spat between HSBC and InfoEdge is where they quote Bikhchandani.

“We value our investments at cost and Info Edge has not marked down Zomato at all,”said Bikhchandani.

Speaking of ostriches with their heads buried in the sand…

Valuing Global Fashion Group

Yesterday, in Mint, I wrote about ratchets in option valuation (a pet topic of mine), and gave alternate valuations of different Indian “unicorns” by accounting for the downside protection clauses that come with startup investment.

Money quote:

This implies that a share of the company held by [investors] includes a long put option, while a share of the company held by earlier investors includes a short put option (since they have implicitly written this option). In other words, a share held by the new investors is worth much more than a share held by earlier investors.

Now comes news that Global Fashion Group (that includes Jabong and a few other fashion houses started by Rocket Internet) has raised money at a “down round”. This gives me a good opportunity to put my theory to practice.

GFG has now raised $339M for a headline valuation of $1.13 billion. In its earlier round, it had raised $169M for a headline valuation of $3.5 billion. Let us look at a hypothetical employee of GFG who owned 0.1% of the company before the previous round of investment, and see what these shares are worth now.

Absence of ratchets

GFG had a “pre-money” valuation of $3.33 billion, and 0.1% of that would have been worth $3.33 million. As of that round of investment, existing investors had 95% stake in the company, so our friend’s share of the company would have come down to 0.095% (95% of 0.1%).

The new round shows a pre-money valuation of $791 million, and so our friend’s stock would be worth $750,000 after the latest round of valuation. This is a comedown from the previous valuation, but is still significant enough.

Presence of ratchets

Let’s assume that the previous round of investment into GFG came with a full ratchet (we’ll look at other downside protection instruments later). This would mean that its investors in that round would have to be compensated for the drop in valuation.

Investors in the previous round put in $169M for a headline valuation of $3.33Bn. The condition of the full ratchet is that is that if this round’s pre-money valuation were to be less than last round’s post-money valuation, the monetary value of last round’s investors has to be the same.

So despite this round showing a pre-money valuation of only $791M, last round’s investors would claim that $169M of that belongs to them (the way this is achieved in an accounting context is that the ratio in which their preferred shares convert to common shares changes). So the earlier investors (who came before last round) see the value of their shares go down to a paltry $622M. From owning 95% of the company, the down-round means they only own 79% now. And that is before the new round has come in.

Investors in the new round have put in $339M for a headline valuation of $1.13Bn, giving them a round 30% stake. Earlier investors have a 70% stake, of which investors who came before the previous round (which includes employees like our friend) have a 79% stake, giving them a net stake of 55%.

Coming back to our friend, remember that he owned 0.1% of the shares before the last round of investment. The ratchet means that he owns 0.1% of 55% of the company’s current headline valuation. This values his shares at $622,000.

But not so fast – since this assumes that the latest round of investment has no ratchets. If we need to take into consideration that this round has a full ratchet as well, the option formula I used in the Mint piece says that GFG is now worth $760M, far lower than the $1.13Bn headline valuation.

This implies that the stock held by investors prior to this round is now worth only $421M ($760M – $339M). Investors prior to the last round held 79% of these shares, so their stake is worth $331M now. Our friend held 0.1% of that, so his stake is only worth $331,000.

In other words, if both the previous and current rounds of investment in GFG came with a full ratchet protection, the shares held by ordinary investors such as our friend would have lost 56% of its value on account of optionality alone! Notwithstanding the fact that the remaining shares are held in a company whose value is on the downswing!

Then again, downside protection for investors could have come by other means, which were less harsh than full ratchet. Nevertheless, this can help illustrate how much of founders’ and employees’ shareholder value can be destroyed using ratchets!

Third party life insurance

An alumnus of IIT Madras has made a contribution to the institute in a very interesting manner. He has assigned IITM as a beneficiary of his life insurance policy. The amount isn’t large – $100,000, which I would think is lower than the median amount insured in pure life insurance (as opposed to insurance combined with investment) policies in India.

The important thing is if there are any regulatory implications of this. Typically, insurance companies don’t allow you to assign your policies to random third party beneficiaries, since it can result in adverse incentives – the random third party can murder you, for example (it’s common, however, for employers to be beneficiaries of key employees’ life insurance). However, things might be different here since the receiving entity is an institution.

If insurance firms are willing to write such policies, I wonder if this could be a scalable and sustainable method to donate to institutions of one’s choice. Or if it is simply better to will the same amount of your life’s savings to go to the institution after your death.

PS: I found the original article on LinkedIn and found it incredibly difficult to link to the text and picture. Hence just put the picture here. Another reason why LinkedIn sucks.

More optionality in startup valuations

Mint reports that Indian e-commerce biggies Flipkart and Snapdeal are finding it hard to raise more money at the valuations at which they raised their last funding rounds. One line from the report:

Despite Morgan Stanley’s markdown in February, Flipkart is still approaching investors asking for a valuation of $15 billion, but it hasn’t had any takers yet, the first two people cited above said.

The problem with the valuations is that it includes significant option value. It is common in startup funding to include implicit options in favour of the new round of investors to protect them from the downside of any future decrease in valuation.

Typically designed in the form of “ratchets”, when the firm raises a fresh round at a lower valuation, the investors in the previous round will get additional shares so that their overall share in the investment remains the same (won’t go into the exact mechanics here). This downside protection allows investors to be more aggressive on their valuations of the company, and the company is able to report higher headline numbers.

Ratchets have two problems, both of which are illustrated in the difficulty of Flipkart and Snapdeal in raising more funds. Firstly, optionality in funding means an automatic markdown of funds held by investors in progressively earlier rounds. This is not explicit, but a ratchet is basically existing investors writing an option in favour of the new investors. While the cost of this option is not explicit, it is the earlier investors who bear the cost.

So Series C (and earlier) investors bear the cost of the optionality given to Series D investors. Series B and earlier investors bear the cost of Series C’s optionality. And so on. Notice that this telescopes, so the founders (original owners of equity) have written options to everyone who has invested (of course they also benefit from the higher overall valuation).

Now, if a “down round” (funding round at lower overall valuation than previous round) happens, this optionality gets immediately gets “paid out”. So if the Series D valuation is lower than Series C valuation, Series B and earlier investors (and founders) immediately “pay” the difference to the Series C investors (these options are American, and usually without an expiry date). So Series B and earlier investors (and especially founders) will not like this round. And they will hunt around for offers that will ensure that they don’t have to pay out on the options they’ve written. I suspect this is what is happening at Flipkart and Snapdeal now.

The second problem with ratchets is that stated valuations are inflated. A common share in Flipkart (don’t think one exists. All investors in that firm are effectively either long or short an option in the same stock) is not valued at $15 billion, so that valuation is essentially a misnomer. When Morgan Stanley says on its books that Flipkart is actually worth $11 billion, it is possible that that is the “true value” of the stock, without accounting for the optionality that latest round of investors receive. In other words, the latest round of investors invested at a price, which if extended to all stock, would value the company at $15 billion. But the rest of the company’s stock is not the same as the stock these investors hold! 

The problem, though, is that the latest “headline valuation” (inclusive of optionality) is anchored in the minds of founders and other earlier investors, and they see any lower price as unacceptable. And so the logjam continues. It will be interesting to see how this plays out.

With IPO being way too far off an event for determining if a company has “arrived” I propose a new metric, with shorter horizon. A company can be declared as having arrived if it manages to raise a round of equity with no embedded options. Think about it!

On the death of credit cards

An article that was recently recommended to me on Medium talks about the death of credit cards (among other things that are currently incumbent in the banking system). As someone who has worked a fair bit in “FinTech”, I broadly agree with what he says. As someone who has worked a fair bit in “FinTech”, I’m also not sure how easy it is to disrupt.

The article says:

The two primary use cases for a credit card today could be illustrated thus:

  1. I’m at the grocery store, swiped by debit card and the transaction was declined because my salary hasn’t yet hit my bank account. I need to buy these groceries for the family today, so I’ll use my credit card and worry about why my salary hasn’t hit the account later, or

  2. I really want this new iPad Pro, but I can’t afford it based on my current savings. If I use a credit card I can pay it off over the next few months

And proceeds to explain why each of the above situations can be unbundled to some kind of an instant credit scenario, rather than the bank having extended a lien to you through which you can borrow.

While the idea of instant credit (on the lines of Affirm) makes intuitive sense, the problem is with transaction costs. Irrespective of algorithms significantly slashing the time required and marginal cost of underwriting loans, the fact remains that the marginal cost of underwriting and extending new credit can never be brought down to zero.

There are costs to updating the information the bank knows about you. There are costs to creating any kind of legal documentation, and insuring that. If you were to list down all such costs, you would find that even if the cost of actual underwriting itself were to be zero, the marginal cost of issuing a loan is significant.

It is for this reason that banks have traditionally settled down on a model of “approve once, borrow multiple times”. For retail borrowers, this translates to a credit card, where they can borrow up to a predetermined limit, with no questions asked for each borrowing. For corporate borrowers, this translates to something like a “working capital lien” or “overdraft”.

The article I’d linked above talks about one of the solutions being an “overdraft”. In that sense, what it says is that the physical credit card might disappear, but not the fundamental principle, which is “approve once, borrow multiple times”.

In fact, as companies come up with new and innovative ways of slashing marginal cost of underwriting to enable “on-demand approval” (I’ve been involved in such efforts with a couple of companies), the question is whether such costs can actually be brought to zero, and if not, whether the model can be sustainable.

As long as the marginal cost of underwriting remains even mildly positive, it is not profitable for lenders to lend out small amounts with “on-demand approval”. How this problem can be solved will determine how well “FinTech” lenders can disrupt banks (on the lending side).
