Ready or Not, Here Comes Basel IV

WASHINGTON — International regulators are gearing up to make significant changes to capital requirements over the next few years in a shift so massive that some observers have already begun talking about under a new name: Basel IV.

Over the next three years, regulators are poised to make sweeping alterations to the existing Basel III international accord, including raising the risk-based capital ratio, revising risk weightings, and moving away from model-based assessments as part of a revamp of the capital requirements for operational, market and credit risk.

"The sum total of all of these is a really new capital regime. It's effectively Basel IV," said Karen Shaw Petrou, managing partner of Federal Financial Analytics, the first analyst to use the term.

The Financial Stability Board detailed many of these changes in a communiqué to the G-20 ahead of its meeting last month in Australia, but few have seized on just how sizable they would be.

The stability board said it will issue a plan for total loss-absorbing capacity — a standard that includes capital and convertible debt and is designed to help make it easier for regulators to seize a failing behemoth. Regulators are calling for TLAC to be at least twice the Basel III total risk-based capital of 8%.

It will make that change at the same time that the board revamps how banks rely on internal risk models to determine capital requirements and implements new standards to "enhance the resilience of banks' funding and their stock of liquid assets," according to the communiqué.

Additionally, the Basel Committee is still finalizing work on capital requirements governing trading books, operational risk and credit risk, Petrou said.

Taken together, it's a seismic shift, analysts agreed.

"What this does is create a floor, and that floor may be appropriate for some and may be unduly high for others," said Gregory Lyons, a partner at Debevoise & Plimpton. "It is a significant move away from allowing institutions with sufficient robust risk management to use their own personal experiences to re-evaluate their capital adequacy."

Petrou points to specific changes she expects to see soon from the Basel Committee. For one, she said it will likely raise the risk-based capital ratio to 10% from 8%.

At the same time, however, the Basel Committee plans to overhaul risk weightings, which received relatively small changes under Basel III. Those changes will reduce reliance on internal or external models and move toward tougher capital standards.

Regulators are making changes because of the flaws with models and risk weightings exposed by the financial crisis and subsequent international events. Basel II, for example, famously assigned a zero capital requirement for sovereign debt. Such "howlers," Petrou said, are the kind of blind spots that regulators want to avoid.

The end result is a shift away from risk-based capital rules and toward simple, hard-line capital ratios, Petrou said. It also means the international capital system, which has long been focused on modeling and risk weighting, is moving closer to the U.S. one, which has continued to rely on a simpler leverage ratio in addition to more risk-based measures.

"We are dragging the Europeans [and] Japanese kicking and screaming away from risk-based capital to a leverage-based, simple model of regulatory capital, even for the most complex financial instruments," Petrou said. "There's a book, and you look it up and that's the capital you have to hold."

Notably, neither the Basel Committee nor regulators are likely to call the changes underway "Basel IV," or indeed give it a name at all. That's partly because the idea of a Basel IV would be unpopular with banks, especially considering Basel III is still being finalized and implemented.

But the Basel accords have a history of incomplete implementation. Basel I was drafted in in 1988 to establish a minimum level of bank capital based on risk-weighting of various assets. Basel II came along in 2004 to revise and update Basel I's framework, but limited capitalization requirements to on-balance-sheet assets, resulting in banks — especially European banks — holding very large positions in sovereign debt.

The U.S., however, did not fully implement Basel II after a bitter fight over the issue between the Fed, which at the time pushed for more reliance on internal models, and the Federal Deposit Insurance Corp., who worried capital requirements would fall too far, too fast. Basel III, which was developed in the wake of the financial crisis, sought to extend capital requirements to off-balance-sheet assets, but largely ignored the risk weightings. That work comprises much of the thrust of what Petrou dubs Basel IV.

Lyons said the transition from one regime to another can be vague, but the changes are substantial enough in this case for the name to apply.

"You end up with kind of a fuzzy line as to when a new regime has started," Lyons said. "I think you could certainly consider this to be a new [regime]. You can call that Basel 3.5 or Basel IV, or you can call it a more strict implementation of Basel III. I think fundamentally the regulators have less faith in internal models than before."

Yes, indeed but that is only because they have not understood their mistake in using credit risk weighted capital (equity requirements for banks).

Let us suppose a perfect credit rating. That perfect credit rating is then considered by the banks and the market in general, and cleared for by interest rates, the size of the exposure and other terms.

And so, when bank regulators order that perfectly perceived credit risk to also be cleared for in the capital of banks, they completely messed it up. A perfectly perceived risk, excessively considered is a highly imperfect reaction to perceived risks.

Let me explain it in the following way:

Figure out the average risk aversion of nannies when letting your kids out to play... that might not be totally correct but ok let us accept that. But, never ever add one nanny's risk aversion to that of another nanny's, because then your kid will never ever be allowed to go out and play.
