Model-Driven Regulation Fueled Bubble, Hobbles Recovery

Five years since the beginning of what some label the "Great Recession," economic growth in the U.S. and Europe remains tepid to non-existent.  Central banks maintain close to 0% interest rates and pump trillions of dollars into the banking system with little or no positive effect on economic growth and job creation.

We search for the causes of our economic malaise in all the wrong places.  Government leaders would do well to look in the mirror.

We will not have solid and sustainable economic recovery unless it is led by the financial sector.  The financial sector will not be able to lead the recovery unless we implement sensible, effective, and efficient regulatory policies.  The confusion sowed by up to 20,000 pages of regulations mandated by the Dodd-Frank Act is precisely what we don't need.

The litany of problems in financial regulation is too long for this article.  So we will focus on just one – the risk-based capital models imposed under the Basel international accords.

The Federal Reserve was enamored with risk-based capital models since at least the 1960s.  It sounds good in theory – riskier categories of assets would have more capital allocated to them than less-risky categories.

The Federal Deposit Insurance Corp. refused to go down this path for several reasons.  Models are necessarily backward looking, not reliable predictors of future events, and introduce pro-cyclicality to bank regulation that results in more pronounced booms and busts. 

Regulators are not particularly qualified to assign risk weightings to various categories of assets.  Moreover, there is pressure for regulators to assign lower risk weightings to certain types of "socially desirable" lending.  Finally, bankers will often find ways to "game" the models.

The FDIC preferred to set a minimum capital level (in the 1980s it was 5% tangible equity to assets).  The examination process was used to require capital above the minimum through on-site evaluation of a bank's assets, liquidity, off-balance sheet exposures, interest rate and other operating risks, earnings, and management.

Two events conspired to change this system during the 1990s.  First, blame for the $150 billion cost to taxpayers of cleaning up the S&L mess was inappropriately placed solely on financial regulators and led to a more "rules based" approach toward bank regulation. 

Second, large banks were competing more globally for business and foreign banks were invading the U.S. market.  Large U.S. banks generally had higher capital requirements than their foreign counterparts and lobbied for a system to put large domestic and foreign banks on the same footing.

Conditions were right for the Basel I and then Basel II international capital accords (Basel II was a disaster so now we are on Basel III).  Basel brought international banks closer together on capital requirements, largely by bringing the top banks down rather than bringing the bottom banks up. 

As feared, governments used the models to steer credit to their favorite sectors.  A loan to Apple, Microsoft or a family drug store would carry a 100% risk weighting.   Sovereign debt – i.e., loans made to the governments writing the rules – was given a zero risk weighting.  Housing loans – another favorite of politicians – were given a 50% risk weight (25% if you securitized the loans and bought back the securities).  Not surprisingly, excessive real estate and sovereign lending followed.

Today the backward looking models are demanding substantially higher capital, encouraging banks to shrink their balance sheets and curtail lending.  Moreover, because the Basel models are applicable throughout the world, nearly every major country is simultaneously mired in same economic quicksand, and none can lead the way out.

Regulation of banks should always be counter-cyclical.  In good times, regulators should pressure banks to slow their growth, tighten their lending standards, and increase their capital and loss reserves.  In times of trouble, regulators should urge banks to continue lending to worthy customers even if capital and reserve ratios decline to some extent. 

The Basel capital accords are a serious policy mistake.  It's time to return to financial supervision that relies on good judgment and on-site examinations.  Models should be no more than a tool to assist management and regulators in the exercise of good judgment.  The current system of model-driven supervision helped create a huge worldwide bubble and is now seriously impeding economic recovery.

2014 Predictions Revisited: What the Seers Got Right and Wrong

A year ago we asked BankThink contributors to make bold predictions about how the financial industry would evolve in 2014. Here's a look back at their forecasts and the actual outcomes.

The question of the wisdom of risk-based capital requirements aside, many bankers and many reformers seem to be speaking different languages. The latter seek a restoration of "boring" banking that was subordinate to nonfinancial business during decades of relative financial stability after the World War II, and doubt that an economy centered on a giant financial sector can generate durable prosperity. The former argue, "We will not have solid and sustainable economic recovery unless it is led by the financial sector." - Harry Terris, data editor, American Banker

hterris1 -- You miss the middle ground we seek. We need a strong, slightly boring, banking system to make sound loans to individuals and smaller businesses and lead the nation into economic recovery. That cannot happen unless we implement far more effective, hands-on regulation that is counter-cylical, not pro-cyclical. The rules-based, model-driven system led us into the abyss and we can't find our way out.

Kovacevich and Isaac nail it. Basel III will eventually destroy the community banking industry. Basel III is a far greater threat to community banks than Dodd/Frank regulations. Basel III in combination with several of the Dodd/Frank regulations are a deadly regulatory Molotov cocktail that will blow up community banks.

I have a lot of respect for the insights of both of these gentlemen, but that horse has already left the barn.

If all banks were run the way Mr. Kovacevich ran his bank then I'd agree 100% But, sadly that is not the case. I've actually spent time reading what various regulatory agencies have said about Basel III. The only community banks that will be at risk from Basil III are very thinly capitalized banks that are doing highly risky lending. I've yet to see any study that actually shows how this will end community banking.

Also, remember that the regulators tried to do something about the growth in commercial real estate (especially development loans) a few year ago and the industry screamed like a stuck hog.

Regulation, or a lack of regulation, did not cause the problems in the banking sector. The problems were caused by poor decisions by management and boards of banks. Had the root cause of the problems been the government then far, far more banks would have failed. Banks fail for the same reason most other businesses fail: poor management and not enough capital to weather the storm.
