One has to applaud the Bank for International Settlements (BIS), the Basel, Switzerland-based bank for the world's central banks, for providing the Federal Reserve with a reality check as to the state of U.S. and global financial markets. More important still, one has to salute the BIS for not pulling punches in reminding the Fed as to the potentially high cost of an overly easy monetary policy, especially if it is maintained for too long. Hopefully, this time around, the Fed will take to heart the BIS's cautionary advice, unlike the case with similar BIS advice in the immediate run-up to the 2008-2009 U.S. housing and financial market bust.
At a time when Federal Reserve Chair Janet Yellen is still managing to convince herself that U.S. equity market valuations are within their normal historical ranges and that it is not yet time to worry about overextended credit markets, in its recently released annual report, the BIS is correctly proclaiming that the U.S. and global financial markets have become excessively frothy. It does so by pointing to the basic disconnect between the financial markets' current buoyancy and the relatively lackluster U.S. and global economic performance. To back up that claim, the BIS observes that market participants are pricing in hardly any risk at all as is underlined by the fact that volatility in equity, fixed income and foreign exchange markets have all sagged to historic lows. Meanwhile, credit spreads have narrowed to very low levels as investors have stretched for yield in a very low interest rate environment.
As to current U.S. economy policy challenges, the BIS is correct in asserting that there are clear limits to what should be expected from monetary policy. This is especially the case once interest rates have already been reduced to exceptionally low levels and once quantitative easing policies have already buoyed equity and credit market prices to artificially high levels. In that setting, it is crucial that monetary policy is supported by more structural reform-type policy measures aimed at improving bank balance sheets, dealing with the debt overhang problem and increasing economic productivity.
Over the past 15 years, a recurrent weakness of Federal Reserve policy has been that of paying too little attention to asset price inflation. Hopefully, the BIS's candid and well-reasoned criticism will shift the Fed away from its habitual tendency to focus almost exclusively on the immediate term and to underestimate the cost of asset price booms and busts. If the Fed does not do so, we should brace ourselves for yet another painful asset and credit market bust once the process of interest rate normalization eventually begins.
