The before and after the risk weighted bank capital adequacy ratio (RWCR)

The risk weighted bank capital requirements were introduced in 1988 by means of the Basel Accord, Basel I, and were much further developed in 2004, with Basel II. RWCR survives in Basel III.

Before RWCR banks, for their return on equity, leaned on savvy bank loan officers to obtain the highest risk adjusted net margins. A net margin of 1.5% when leveraged 10 times on their equity, would produce a 15% ROE. All wanting access to bank credit, whether perceived as safe or risky, competed equally with their risk adjusted net margin offers.

After the introduction of RWCR though banks, for their return on equity, still leaned somewhat on bank loan officers obtaining the highest ROE depended more on equity minimizing financial engineers. A risk adjusted net margin of 1%, when leveraged 20 times on equity, produces a 20% ROE. The risk adjusted net margin offers of those perceived or decreed as safe, which could be leveraged many times more, were now worth much more than those offered by the risky.

And what are the consequences?

The RWCR by favoring the financing of the “safer present” like sovereigns, residential mortgages and what’s AAA rated over the financing of the “riskier future, like entrepreneurs, leads to a more obese and less muscular economy.

All that RWCR really guarantees is especially large bank crisis, caused by especially large exposures to something perceived or decreed as especially safe, and that turn out to be especially risky, while being held against especially little bank capital. 

So what went wrong? Simply that regulators based their capital requirements on the same perceived risks that bankers already consider when they make their lending decisions, and not on the conditional probabilities of what bankers do when they perceive risks.

Any risk, even if perfectly perceived, will lead to the wrong actions, if excessively considered.

My letter to the Financial Stability Board

Why are regulators allowed to introduce odious and dangerous discrimination in the access to bank credit?

Banks used to apportion their credit between those perceived as risky, and those perceived as safe, based on (1) the risk adjusted interest rates and (2) their own portfolio considerations.

But that was before the Basel Committee for Banking Supervision’s credit risk weighted capital requirements.

Now banks apportion credit between those perceived as risky and those perceived as safe, based on (1) the risk-adjusted interest rates (2) the times their bank equity can be leveraged with those risk-adjusted interest rates and (3) hopefully, since those risk weighted capital requirements are explicitly portfolio invariant, their own portfolio considerations.

That means the risk adjusted interest rates “the safe” now can offer in order to access bank credit have been lowered, while the risk adjusted interest rates “the risky” have to offer in order to access bank credit have been increased.

That has leveraged whatever natural discrimination in access to bank credit there was against the “riskier” in favor of the “safer”.

That dangerously distorts the access to bank credit in favor of the “safer” present, like sovereigns, house purchases and the AAA rated and against the “riskier” future, like entrepreneurs; which means that our banks have no other social purpose to fulfill than being safe mattresses into which stash away our savings.

And all so useless because the only thing these regulations guarantee, is especially large bank crisis, caused by especially large exposures to something perceived or decreed as especially safe, and that turn out to be especially risky, while being held against especially little bank capital. 

My comments to the Financial Stability Board

What if taking down our bank systems was/is an evil masterful plan for winter to come?

Tweets on "What if taking down our bank systems was/is an evil masterful plan for winter to come?"

The poison used is that of basing bank capital requirements on ex ante perceived risks, more risk more capital, less risk much less capital.

That way banks were given incentives to build up the largest exposures to what is ex ante perceived by bankers as safe, something which, as we know, in the long run, when ex post some of it turns out very risky, is what always take bank systems down.

For that they made sure no one considered making the risks conditional on how bankers perceive the risks.

And that hurdle cleared, some very few human fallible credit rating agencies were given an enormous influence in determining what is risky and what is safe.

And taking advantage of some statists or that few noticed, sovereigns were assigned a 0% risk weight, while citizens 100%. That guaranteed government bureaucrats got too much of that credit they’re not personally responsible, and e.g. the entrepreneurs too little.

And to make the plan even more poisonous some European authorities were convinced to also assign to all Eurozone sovereigns a 0% risk weight, and this even though these all take up loans in a currency that is not their domestic printable one.

And because banks were allowed to leverage much more with “safe” residential mortgages than with loans to “risky” small and medium businesses, houses prices went up faster than availability of jobs, and houses morphed from homes into investment assets

And finally, by means of bailouts, Tarps, QE’s, fiscal deficit, ultra low interest rates and other concoctions, enormous amounts of financial stimuli was poured on that weak structure… and so the evil now just sit back and wait for winter to come

PS. At the World Bank I warned that assigning too much influence to credit rating agencies introduced a dangerous systemic risk. 

PS. My letter to the Financial Stability Board

Risk weights are to access to credit what protectionist tariffs are to trade, only more pernicious.

A letter to the Executive Directors and Staff of the International Monetary Fund.

For decades now IMF has helped to spread around all developing countries the pillar of the Basel Committee’s bank regulations; the risk weighted capital requirements for banks.

Since risk taking is in essence the oxygen of any development, that piece of regulation is fundamentally flawed, especially for developing countries.

How do risk weighted capital requirements alter the incentives for banks? 

If banks hold the same capital against their whole portfolio, as they used do until some three decades ago, then with an eye on their overall portfolio and funding structure, banks lend in accordance to what produces them the highest risk adjusted interest rate; which would also provide them with the highest risk adjusted return on equity.

But, when different assets have different capital requirements, obtaining the highest risk adjusted return on equity will depend on how many times the risk adjusted interest rate for any specific loan or asset will depend on how many times it can be leveraged. The higher the allowed leverage is, the easier it is to obtain a high ROE; which means that “safe” highly leveregable loans could be competitive at lower risk adjusted interest rates than before, while “risky” lower leveregable loans would require paying higher risk adjusted interest rates. 

In essence the introduction of that regulation has caused banks to substitute savvy loan officers with equity minimizing engineers.

How do risk weighted capital requirements distort the allocation of bank credit?

The regulators based their decision on how much banks were allowed to leverage their capital with for the different assets, solely on the perceptions of credit risk. It never explicitly had one iota to do with banks fulfilling their obligation of allocating credit efficiently to the real economy.

So the introduction of that regulation simply distorts the allocation of bank credit; in favor of “the safer present” and against “the riskier future”. 

“A ship in harbor is safe, but that is not what ships are for”, John A Shedd.

Specifically, a credit that is perceived as risky but that is directly related to helping reach a Sustainable Development Goal is much less favored by bankers, and now by bank regulators too, than a credit, perceived as safe, but which purpose could in fact be harmful to any SDG.

Specifically, safe credits for the purchase of houses are much more favored over credits to risky entrepreneurs, those who could create the jobs that would allow the income needed to service the mortgages and pay the utilities. 

Specifically, assigning lower risk weights to the sovereign than to citizens de implies de facto a statist belief that bureaucrats know better what to do with bank credit, than entrepreneurs who put their name on the line.

In other words these risk weight are to access to credit what tariffs are to trade, only much more pernicious. 

Do risk weighted capital requirements make our banks system safer?

If that regulation made the financial system safer there would at least be a favorable tradeoff. But it doesn’t, much the contrary. Too much easy credit can turn what is safe into something risky, like for instance morphing houses from being affordable homes into investment assets. 

The 2007/2008-bank crisis would never have happened or, if so, remotely had been of the same scale had regulators, for their risk weights, instead of perceived credit risk risks, used the probabilities of banks investing conditioned on how credit risks were perceived.

Many Eurozone sovereigns would not face current high levels of indebtedness had not EU authorities decreed a Sovereign Debt Privilege and assigned it a 0% risk weight, this even though they take on debt denominated in a currency that de facto is not their domestic printable one.

And so, at the end of the day, this regulation only guarantees especially large bank crisis, caused by especially large exposures to what was perceived (or decreed) as especially safe, which end up being especially risky, and are held against especially little capital.

Risk weighted capital requirements and inequality.

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… the poor risk… is another name for the poor man.” “Money: Whence it came where it went” 1975.

So I ask, how many millions of SMEs and entrepreneurs have not been given the opportunity to advance with credits over the last 25 years as a direct result of it?

IMF, please, wake up!

Should banks not be regulated? 

Of course these need to be regulated! I am only reminding everyone of the fact that the damage dumb bank regulators can cause when meddling without taking enough care, by far surpasses anything the free market can do. A free market would never have knowingly allowed banks to leverage 62.5 times their equity like regulators did, only because some very few human fallible credit rating agencies had assigned an AAA to AA rating to some securities backed with mortgages to the US subprime sector. 

A simple leverage ratio between 10 to 15% for all banks assets would be a much mote effective regulation than all those thousands of pages that currently exist.

And please, please, please, stop talking about "deregulation" in the presence of such an awful and intrusive mis-regulation. The regulators imposed the worst kind of capital controls.

Of course, just in case, all problems here referred to, are clearly applicable to developed economies too.

PS. “The assets assigned the lowest risk, for which capital requirements were therefore low or nonexistent, were those that had the most political support: sovereign credits and home mortgages.

PS. My 2019 letter to the Financial Stability Board

PS. An ever growing aide memoire on Basel Committee’s many mistakes.

PS. The risk weighted bank capital requirements utterly distorted central banks’ monetary policy by directing way too much credit to what’s decreed or perceived as “safe”, sovereign/ residential mortgages/ AAA rated; and way too little to “risky” SMEs and entrepreneurs.

PS. Because it would also create distortions I am not proposing it, but would not risk weighted bank capital requirements based on SDGs ratings at least show more purpose for our banks? And, in the case of sovereigns, besides credit ratings, do we citizens not also need ethic ratings?

My Fourth of July 2019’s tweets to the United States of America

This Fourth of July 2019, here below, are three tweets in which, to the United States of America that I admire and am so grateful to, I express my very heartfelt concerns.

In 1988 America signed on to the Basel Accord’s risk weighted capital requirements for banks. 

These gave banks huge incentives to finance what was perceived as safe, and to stay away from the “risky”. 

It is so contrary to a Home of the Brave opening opportunities for all.

And bank regulators decreed risk weights: 0% sovereign, 100% citizens

That implies bureaucrats know better what to do with credit than entrepreneurs

That has nothing to do with the Land of the Free, much more with a Vladimir Putin’s crony statist Russia

America, where do you think you would be if you had welcomed all your immigrants with risk weighted bank capital requirements?

PS. “grateful to”? Had my father, a polish soldier not been rescued by American’s from a German concentration camp April 1945, I would not be.

PS. As one of those millions Venezuelan in exile, I know my country’s future much depends on America’s will to support its freedom.

The risk weighted bank capital requirements should at least, as a minimum, have been based on conditional probabilities. They weren’t.

Here a set of tweets on P(A/B)

In probability theory, conditional probability is a measure of the probability of an event (A) occurring (like bankers lending too much to someone safe), given that another event (B) has occurred (that bankers had perceived that someone as very safe).

In probability theory, conditional probability is a measure of the probability of an event (A) occurring (like bankers lending too much to someone risky), given that another event (B) has occurred (that bankers had perceived that someone as very risky).

Any regulators knowing something about conditional probability would never have assigned, for the purpose of risk weighted bank capital requirements, a risk weight of 20% to the very safe AAA rated, and one of 150% to the very risky below BB-rated.

Not the first time I've written about it

PS. Here is my letter to the Financial Stability Board

De riskvägda bankkapitalkraven borde åtminstone ha baserats på betingade sannolikheter. Det var de/är de inte.

Här några tweets om P (A / B)

I sannolikhetsteori är betingat sannolikhet sannolikheten för att en händelse (A) inträffar (som att banker lånar för mycket till någon säker), med tanke på att en annan händelse (B) har inträffat (att bankirerna hade uppfattat denne någon som mycket säker).

I sannolikhetsteori är betingat sannolikhet sannolikheten för att en händelse (A) inträffar (som att  banker lånar för mycket till någon riskabel), med tanke på att en annan händelse (B) har inträffat (att bankirerna hade uppfattat denne någon som mycket riskabel).

Ingen tillsynsmyndighet som vet något om betingad sannolikhet skulle aldrig ha tilldelat, med tanke på riskvägda bankkapitalkrav, en låg riskvikt på bara 20% till de bedömda som mycket säkra AAA, och en hög 150% till de bedömda som mycket riskabla lägre än BB-
