Some tweets on macro-imprudent policies

I tweeted this to BIS in response to a speech by Mario Draghi, President of the European Central Bank and Chair of the European Systemic Risk Board, titled "Macroprudential policy in Europe" delivered September 26, 2019

Macro-imprudent policy 1:

Regulators have based their risk weighted bank capital requirements on that what’s perceived as risky is more dangerous to our bank systems than what is perceived, decreed or concocted as safe. That puts bank crises on steroids.

Macro-imprudent policy 2:

The risk weighted bank capital requirements are as procyclical it can get. Getting rid of these is the best countercyclical measure.

Macro-imprudent policy 3:

The 0% capital requirements assigned to all Eurozone sovereigns’ debts, even when these are not denominated in their own printable fiat currency. This WILL blow up the Euro and perhaps, sadly, the EU too.

The “experts” in the independent agencies, those most likely to introduce systemic risks, must be continuously questioned and supervised.

Paul Tucker for more than 30 years a central banker and a regulator at the Bank of England writes in his "Unelected Power" 2018

“Unlike price stability, the authorities cannot ‘produce’ financial stability by their own efforts but must stop or deter private intermediaries from eroding the system’s resilience.

That cannot be delivered by looking at intermediaries one by one because the financial system is just that - a system, with components parts connected within sectors and markets, via interactions with the real economy, and across countries. 

As the first chairman of the Basel Supervision Committee, George Blunden said in the mid-1980s: It is part of the [supervisors] job to take a wider systemic view and sometimes to curb practices which even prudent banks might, if left to themselves, regard as safe.”

And yet with Basel I in 1988, Basel II in 2004 and current Basel III the regulators in the Basel Committee, ignoring the system, ignoring the distortions it causes in the allocation of credit to the real economy and ignoring that no major bank crisis have resulted from excessive exposures to what ex ante was perceive as risky, went ahead and introduced that mother of all systemic risk and procyclical regulation, which is the risk weighted capital requirements for banks.

“Curb practices which even prudent banks might, if left to themselves, regard as safe”? No way, it only guarantees especially large exposures, to what is especially perceived as safe, against especially little capital, laying the ground for especially large crisis.

I did note that in the 568 pages of “Unelected Power” I found no explicit reference to the risk weighted capital requirements for banks.

At the end of his book Paul Tucker suggests “The principles for delegating to independent agencies insulated from day to day politics”. I agree with these. Had they been in place Basel I II or III would not have existed. Just for a starter, in all of Basel’s bank regulations there is not one single word about the purpose of the banking system, one that must surely contain the need to allocate credit efficiently to the real economy.

There is one aspect though that is not sufficiently laid out in Tucker’s principles and that is the absolute must for the independent agency to contain sufficient diversity, not only to foster better discussion but also in order to hinder, as much as possible, these turning into closed mutual admiration clubs.

PS. In the 568 pages of “Unelected Power” I found no explicit reference to the risk weighted capital requirements for banks, those which for a start caused the 2008 crisis. 

Here is a current summary of why I know the risk weighted capital requirements for banks, is utter and dangerous nonsense.

What goes up too much must come down too much. The best countercyclical policy there is is the elimination of the procyclical ones.

Governor Lael Brainard on December 07, 2018, in “Assessing Financial Stability over the Cycle” a speech delivered at the Peterson Institute for International Economics, Washington, D.C., said:

“In an economic downturn, widespread downgrades of these low-rated investment-grade bonds to speculative-grade ratings could induce some investors to sell them rapidly--for instance, because lower-rated bonds have higher regulatory capital requirements or because bond funds have limits on the share of non-investment-grade bonds they hold.”

And Brainard then proceeds to extensively describe the advantages of countercyclical capital requirements (CCyB) for building additional resilience in the financial system.

BUT, the other side of the mirror is: In an economic upturn, higher credit ratings of bonds could induce some investors to buy them rapidly--for instance, because higher-rated bonds have lower regulatory capital requirements, or because bond funds have lesser or no limits on investment-grade bonds they hold.

So if that is not procyclical what is?

Therefore, before thinking of using countercyclical capital requirements, which by themselves might be introducing distorting signals, which might make the use of these at the right moment when they are really needed harder, let’s get rid, altogether, of the risk weighted capital requirements for banks. Those, which, by the way, even when the economic cycles are correctly identified, still distort the allocation of bank credit to the real economy.

And since credit ratings were mentioned in April 2003, at the World Bank I opined:

"Nowadays, when information is just too voluminous and fast to handle, market or authorities have decided to delegate the evaluation of it into the hands of much fewer players such as credit rating agencies. This will introduce systemic risks in the market"

PS. Here my 2019 letter to the Financial Stability Board

PS. Here my 2019 letter to the IMF

ECB’s Sabine Lautenschläger explains why the risk weighted capital requirements for banks is total lunacy but, unfortunately, not even she hears it.

I quote the following from ECB’s Sabine Lautenschläger’s speech on February 15, 2018, “A stable financial system – more than the sum of its parts” 

“Logic can be a tricky thing. Apply it in the right way, and you always arrive at a consistent conclusion. But apply it in the wrong way, and it can lead you astray. And that happens all too easily. There are indeed many wrong ways in which we can apply logic.”

One of them is known as the fallacy of composition. It refers to the idea that the whole always equals the sum of its parts. Well, that idea is wrong. As we all know, the whole can be more than the sum of its parts – or less.

Consider this statement: if each bank is safe and sound, the banking system must be safe and sound as well. By now, we have learnt the hard way that this might indeed be a fallacy of composition.

Let me give you just one example. Imagine that a certain asset suddenly becomes more risky. Each bank that holds this asset might react prudently by selling it. However, if many banks react that way, they will drive down the price of the asset. This will amplify the initial shock, might affect other assets, and a full-blown crisis might result. Each bank has behaved prudently, but their collective behaviour has led to a crisis.

The business of banking is ripe with externalities, with potential herding and with contagion. These factors may not be visible when looking at individual banks, but they can threaten the stability of the entire system. This is one of the core insights from the financial crisis.”

Let me comment on the implications of this quite lengthy quotation: 

First: “a certain asset suddenly becomes more risky” That means that the real problem is that it was perceived as safer before.

Second: “The business of banking is ripe with externalities, with potential herding and with contagion.” There can be no doubt that potential herding” is much mote likely to occur with assets perceived as safe.

So what is Sabine Lautenschläger really saying with all this? That the current risk weighted capital requirements, Pillar 1, more perceived risk more capital – less perceived risk less capital, is sheer lunacy, though she might not understand it. 

The truth is that the real logic, not that pseudo logic applied by bank regulators, is that the safer an asset is perceived, the greater the potential danger to the bank system it poses.

Lautenschläger also said: “Imagine that there is a downturn in the financial cycle. From the viewpoint of each bank, credit risks increase and microprudential supervisors may want to increase Pillar 2 capital demands. Looking at the same trend, macroprudential supervisors might want to support credit growth and counter the cycle over a longer time horizon and from a systemic point of view. Thus, they may want to decrease Pillar 2 capital demands.”

“credit risks increase” That goes in the direction from safer to riskier. Does going from riskier to safer pose any danger? No!

So is not assigning the lowest capital requirements to what is ex ante perceived as safe just the mother of procyclical regulations, or in other words, the mother of all macroprudential imprudences? 

Ex post dangers are a function of ex ante perceptions. The safer something is perceived the more real danger it poses. The riskier something is perceived, the less harm it can cause.

How on earth could one expect a good application of Basel Committee’s Pillar 2 (Supervisory Review Process) from those who are messing it all up with a so faulty Pillar 1?

Recommendation: Ask a regulator: “What is more dangerous to the bank system, that which is perceived risky or what is perceived safe?” If he answers, the “risky”, ban him from regulating banks.

IMF, the Basel Committee’s procyclical risk weighted capital requirements puts financial cycles, global or local, on steroids

This year’s IMF Jacques Polak Annual Research Conference on November 2–3 is titled “The Global Financial Cycle.” 

It aims to bring together contributions by leading experts on the topic—from both within and outside the IMF—to improve the “understanding of a range of issues, including the causes and consequences of the global financial cycle, the transmission channels of global financial shocks, and the role of domestic policies in dampening the impact of global shocks.”

I wonder if, again, for the umpteenth time, the distortions produced by risk weighted capital requirements in the allocation of credit to the real economy will be ignored.

The following is the comment I posted on the IMF Blog

Risk weighted capital requirements, more risk more capital – less risk less capital, allows banks to earn much higher risk adjusted returns on equity with what is perceived decreed or concocted as safe, than on what is perceived as risky. 

That pushes more than ordinary the financial pursuit of “the safe” and the avoidance of “the risky”.

That de facto puts financial cycles, whether global or local, on steroids.

Will this comment be considered? I have not seen much action on the one I made last year.

PS. I have now read all the papers presented in the conference and the only one that makes somewhat of a reference to risk weighted capital requirements, is “Global financial cycles and risk premiums?” authored by Oscar Jorda, Moritz Schularick, Alan M. Taylor and Felix Ward, October 2017

It includes “If banks hold foreign assets on their balance sheets and mark them to market, price changes can synchronize the risk appetite and the trading behavior of banks around the world. For instance, if Federal Reserve policy affects U.S. equity prices, falling asset prices in the U.S. decrease (risk-weighted)-asset-capital ratios of U.S. as well as international banks, which start to cut down their risk-taking in sync with U.S. banks.

If no large risk-neutral player steps in to compensate for the lower risk taking of the leverage-constrained intermediaries, risk-spreads will increase.”

But as one can see that is how financial cycles or event affect “(risk-weighted)-asset-capital ratios”, but not how these risk weighted capital requirements affect the financial cycles.

For instance Greece would never ever have been able to obtain so much debt had it not been for the ridiculous low capital requirements on that debt.

Credit ratings do not reflect timely possible severe drops in commodity prices or volatile monetary policies

What is happening with commodities, like oil, and with emerging countries should open the eyes of bank regulators… but probably it won’t. 

Our bank nannies based their requirements of that capital that is to cover for unexpected losses on what they perceived as the one and only risk, namely the ex ante perceived expected credit risk… in much as it was reflected in the credit ratings. 

And the credit rating agencies rate the companies based on what they currently see. 

Where did the credit ratings reflect the possibility of a dramatic drop in the price of oil before it happened? Nowhere! 

Where do credit ratings consider the consequences, like for emerging markets, of shocking volatile monetary policies before they hit the market? Nowhere! 

And so now there is a lot of downgrading going on, and as a result lots of new capital is being required of banks, something that only accentuates the general downturn. 

The truth is that banks should already have had the capital to cover for unexpected losses, when they placed the assets on their balance sheets.

You need not to be an Einstein to know that current bank regulations are procyclical.

Jon Cunliffe, Deputy Governor for Financial Stability of the Bank of England spoke on November 15, 2015 about “The outlook for countercyclical macro prudential policy”

He began with: “It is an interesting experiment to think what Einstein might have accomplished had he chosen the world of economics rather than physics. Would he have brought to our world the same brilliant simplicity and achieved the same lasting change in our understanding?”

I have no idea what Einstein would have done in such case but I am absolutely certain about what he would not have done.

He would not have set up pro-cyclical credit risk weighted capital requirements for banks, those which are lower for what is perceived as safe than for what is perceived as risky; those which allow banks to leverage more with what is perceived as safe than what is perceived as risky; those which therefore allow banks to earn higher risk-adjusted returns on what is perceived as safe than on what is perceived as risky; those which therefore in Mark Twain’s supposed words make bankers lend you the umbrella even faster than usual when the sun is out and take it away even faster than usual when it looks like it is going to rain.

When times are rosy and so much can seem safe, then banks need to hold little capital and so when times get bad, and so much seems risky, then banks, on top of their difficulties must also come up with additional capital or shed assets. No Mr Cunliffe Einstein would never have done a stupid thing like that.

Einstein would also have understood that the safer an asset is perceived the larger is its potential to deliver those unexpected losses that bank equity is to serve as a buffer against. To set capital requirements based on the ex ante expected credit losses is as dumb as it gets.

And Einstein would of course, before regulating the banks have asked: “What is the purpose of banks?” And when stress-testing banks, besides looking at what is on their balance sheets, Einstein would also have looked at what is not and perhaps should be.

But come to think of it… you should not be an Einstein to get all this!

With respect to developing countercyclical macro prudential policy Cunliffe expresses “I have some sympathy of the ‘don’t do it at all’ approach.

Yes Mr. Cunlifee. The regulators have done more than enough damage as is. Just eliminate the re-clearing in the capital of the perceived credit risk that has already been cleared for with interest rates and the size of the exposure. Don’t you understand that any risk, even though perfectly perceived, leads to the wrong actions if excessively considered?
