The main causes the so objectionable risk-weighted bank capital requirements are not objected.

A brief summary:

No understanding about what immense hubris “experts” are capable of, like believing they can weigh bank capital requirements for perceived credit risks… and then mostly ignoring misperceived risks and unexpected events e.g., pandemic war.

No understanding of how allowing banks to leverage their capital differently with different assets, will make it easier/harder for banks to obtain the desired risk adjusted returns on equity; something which distorts the allocation of credit.

No knowledge about conditional probabilities; which therefore helps to believe those excessive exposures that could become truly dangerous to bank systems, are built up with assets perceived as risky.

Not understanding that risk-taking is the oxygen of all development.

Consequentially:

No understanding of their pro-cyclicality. When risks are perceived low, credit ratings are high, banks can hold little capital, buy back stock, pay much dividends and bonuses, and so, when times worsen, or something unexpected like a pandemic or a war occurs, banks will stand there naked, precisely when it would be the hardest for them to raise new capital, precisely when we need them the most

No understanding of that since the capital requirements are lower for lending to the “safe” government than to the risky citizens, this implies bureaucrats/politicians know better what to do with (taxpayer’s) credit than e.g., small businesses and entrepreneurs. (Of course, they could also be agreeing with that for pure ideological considerations.)

No understanding of what capital requirements being lower for “safe” residential mortgages than for loans to risky small businesses and entrepreneurs, implies to the possibilities of generating the jobs/incomes needed to service mortgages and pay living costs.

The saddest part is that all these limitations seem to entirely apply to our current Academia. 

Any risk, even if perfectly perceived, causes the wrong answer to it, if excessively considered.

Any risk, even if perfectly perceived, causes the wrong action, if excessively considered.

“A banker is a fellow who lends you his umbrella when the sun is shining, but wants it back the minute it looks to rain” Mark Twain (supposedly)

And Mark Twain is right in that bankers, in general are risk adverse and, when they accept taking some, it is usually in small amounts and against high risk premiums.

And, for around 600 years, bank credit was allocated, usually with a view on the portfolio, based on risk adjusted net interest rates.

But then, in 1988 with Basel I, the Basel Committee introduced (I would say ‘concocted’ is a more precise term) the concept of risk weighted bank capital requirements, based on exactly the same credit risk aversion.

With that the regulators ignored that any risk, even if perfectly perceived, causes the wrong answer to it, if excessively considered.

If Twain was alive he could just as well be writing: “A bank regulator is a fellow that allow banks to hold little capital when the sun is shining, so that banks can pay lots of dividends and buy back lots of stock, but wants banks to hold much more capital, the moment it starts to rain”

And, since then, bank credit is allocated based on risk adjusted returns on equity and, of course, the higher the allowed leverage is the easier it is to obtain a higher return on equity.

John A. Shedd (1859 – 1928) wrote “A ship in harbor is safe, but that is not what ships are for”. And that should also apply to banks. Unfortunately, these capital requirements guarantee that banks stay in safe harbors, running the risk of dangerously overcrowding these, and stay away from the risky oceans, and most certainly not lending enough to those “risky” entrepreneurs and SMEs on which our real economies so much depend.

In his book “Money: Whence it came, where it went” (1975), John Kenneth Galbraith wrote “The function of credit in a simple society is, in fact, remarkably egalitarian. It allows the man with energy and no money to participate in the economy more or less on a par with the man who has capital of his own. And the more casual the conditions under which credit is granted and hence the more impecunious those accommodated, the more egalitarian credit is”

By doubling up on credit risk, the regulators made it so much more difficult for banks to fulfill such important societal function.

And it’s all so much worse. With their much lower bank capital requirements on loans to governments than on loans to citizens, statist/communist/ fascist regulators de facto imply bureaucrats/politicians know better what to do with credit for which repayment they’re not personally responsible for, than e.g. entrepreneurs.

And it is all so stupid. There’s never ever been a major bank crisis caused by the buildup of excessive exposures to what’s perceived as risky, those exposures have always been built up with assets perceived as safe.

The regulators, by basing most of their pro-cyclical bank capital requirements on perceived credit risks; not on misperceived credit risks, or unexpected dangers, like a pandemic, guaranteed all banks now stand there with their pants down. Basel Committee, Good Job!

The Basel Committee for Banking Supervision’s bank regulations vs. mine.

A tweet to: @IMFNews, @WorldBank, @BIS_org @federalreserve, @ecb @bankofengland @riksbanken @bankofcanada

"Should you allow the Basel Committee to keep on regulating banks as it seems fit, or should you not at least listen to other proposals?

Bank capital requirements used to be set as a percentage of all assets, something which to some extent covered both EXPECTED credit risks, AND UNEXPECTED risks like major sudden downgrading of credit ratings, or a coronavirus.

BUT: Basel Committee introduced risk weighted bank capital requirements SOLELY BASED ON the EXPECTED credit risk. It also assumes that what is perceived as risky will cause larger credit losses than what regulators perceive or decreed as safe, or bankers perceive or concoct as safe. 

The different capital requirements, which allows banks to leverage their equity differently with different assets, dangerously distort the allocation of bank credit, endangering our financial system and weakening the real economy.

The Basel Committee also decreed a statist 0% risk weight for sovereign debts denominated in its domestic currency, based on the notion that sovereigns can always print itself out of any problem, something which clearly ignores the possibility of inflation, but, de facto, also implies that bureaucrats/politicians know better what to do with bank credit they are not personally responsible for, than for instance entrepreneurs, something which is more than doubtful.

Basel Committee's motto: Prepare banks for the best, for what's expected, and, since we do not know anything about it, ignore the unexpected 

I propose we go back to how banks were regulated before the Basel Committee, with an immense display of hubris, thought they knew all about risks; which means one single capital requirements against all assets; 10%-15%, to cover for the EXPECTED credit risk losses and for the UNEXPECTED losses resulting from wrong perceptions of credit risk, like 2008’s AAA rated securities or from any other unexpected risk, like COVID-19.

My one the same for all assets' capital requirement, would not distort the allocation of credit to the real economy.

My motto: Prepare banks for the worst, the unexpected, because the expected has always a way to take care of itself.

What would Hyman Minsky say if able to observe how his financial instability moments were put on steroids by bank regulators?

On Minsky moments

“In many cases even trying to regulate banks runs the risk of giving the impression that by means of strict regulations, the risks have disappeared. History is full of examples of where the State, by meddling to avoid damages, caused infinite larger damages”

“Old agricultural traditions of burning a little each year, thereby getting rid of some of the combustible materials, was much wiser than no burning at all, which only guarantees disaster and scorched earth, when fire finally breaks out, as it does, sooner or later. Therefore a regulation that regulates less, but is more active and trigger-happy, and treats a bank failure as something normal, as it should be, could be a much more effective regulation. The avoidance of a crisis, by any means, might strangely lead us to the one and only bank, therefore setting us up for the mother of all moral hazards—just to proceed later to the mother of all bank crises.”

“Everyone knows that, sooner or later, the ratings issued by the credit agencies are just a new breed of systemic errors, about to be propagated at modern speeds”

The Basel Committee’s credit risk weighted bank capital requirements cause our banks to be dangerously overexposed to what’s expected, and to be woefully unprepared for the unexpected. 

Current risk weighted bank capital requirements guarantee especially large bank crises, caused by especially large exposures to what’s perceived as especially safe but might not be, and is held against especially little capital.

"A mixture of thousand solutions, many of them inadequate, may lead to a flexible world that can bend with the storms. A world obsessed with Best Practices may calcify its structure and break with any small wind."

My bank regulator went to Basel, and all he brought me was this lousy credit risk weighted capital requirements

I sent my bank regulator to learn with the big boys in the Basel Committee for Banking Supervision about how to regulate banks. Among what he was supposed to pick up was an idea of how much capital he should require banks to hold, primarily against any unexpected losses.

He could have come back with capital requirements that considered all type of events that unexpectedly could blow a hole in a banks solvency like: cyber-attacks, a weather event with disastrous consequences, a major earthquake, the central banks or even the regulators themselves not knowing what to do, inflation suddenly popping up, crazy governments (I am from Venezuela), a set of important companies suddenly turning up engaged in some hanky panky, Systemic Important Financial Institutions (SIFIs) going belly up, internal or external fraud, a major loss from an authorized or unauthorized position in a speculative trading, unexpected consequences from new regulations and thousand of other things… BUT NO all he brought me was this silly risk weighted capital requirements based on expected credit risks, about the only risks banks are supposed to really take care of on their own.

If only it had been based on the risk that banks were not able to manage expected credit risk, then I could have accepted it… but that had of course nothing to do with the credit risk per se, in fact usually it is what is perceived as safe that could pose the biggest dangers for a bank. 

And, to top it up, these credit risk based capital requirements were portfolio invariant, meaning independent of the size of the exposures, only because otherwise it would be too hard for him and his regulating colleagues to handle.

And, to top it up, these credit risk based capital requirements also smuggled in the absurd statist notion that sovereigns were infallible, de facto implying government bureaucrats knew better what to do with bank credit than "the risky" SMEs and entrepreneurs.

And to top it up, during his whole stay with the Basel Committee, and during his study visits to the Financial Stability Board and the IMF, not one single word was said about the societal purpose of banks.

And, so these credit risk based capital requirements guarantees to dangerously distort the allocation of bank credit to the real economy... which they did, look at how much credit Greece got... which they do, look at how little credit SMEs get.

And so these credit risk based capital requirements now guarantee that the next time a bank crisis results from excessive exposures to something that was erroneously perceived as very safe, which is precisely the stuff major bank crisis are made of, then banks will stand there with their pants down and no capital to cover themselves up with.

No! I will surely never ever send my bank regulator to Basel again.

Our current bank regulators are dangerous fools.

Bank regulators foolishly allow banks to hold much less capital against assets which are perceived as “safe” than when holding assets perceived as “risky”. 

That means that bank regulators foolishly allow banks to leverage their capital many times more when holding assets which are perceived as “safe” than when holding assets perceived as “risky”. 

And that means that bank regulators foolishly allow banks to earn a much higher expected risk-adjusted return on equity when holding assets perceived as “safe” than when holding assets perceived as “risky”. 

And I say “foolishly” because with that bank regulators introduce a distortion that makes it absolutely impossible for banks to perform their vital social function of allocating resources efficiently. 

And I say “foolishly” because that guarantees that when something ex-ante perceived as safe, ex post turns out to be risky, bank exposures to it will be huge, and the bank capital to cover for it totally insufficient. 

And I hold our current bank regulators to be dangerous fools, because they don´t even understand the harm their capital requirements based on perceived risk of Basel II does to our banking system and that it caused the current crisis; and because they now want to dig us even deeper down into the hole with Basel III adding liquidity requirements which are also based on perceived risk. 

A bank is there to take intelligent risks on behalf of the risk-adverse society, and not to be treated as just another widow or orphan by some dumb overanxious nannies.

A perfect depiction of our bank regulators… looking out in the same direction of bankers for what is perceived as risky, forgetting that in banking, as in so much other, what is really risky is what is considered absolutely safe. (Thanks "Learning from dogs" for the heads up for the photo)
