Ben Bernanke Warned Us

The Fed chairman’s 10-year-old talk offers a remarkable forecasting device. It explained how, in an extreme situation, traditional monetary policy tools, even bringing short-term interest rates down to zero, might not produce enough stimulus, and it listed the “non-traditional” policies the Fed might employ: 1) purchasing longer-dated Treasury, agency, and mortgage-backed securities; 2) announcing an intention to keep short rates low for an extended period; and 3) injecting liquidity into financial markets by accepting corporate bonds, bank loans, commercial paper and mortgages, among other securities, as collateral for direct lending to banks. All these tools made appearances during the 2008-09 financial crisis and have lingered in its aftermath. A fourth technique Bernanke mentioned in 2002 involved purchasing the debt of foreign governments. The Fed has yet to do so, but it might if there is any further deterioration in Europe.

Behind all of these measures, Bernanke’s talk pointed to the growth of money and liquidity as the ultimate policy objective to get the economy moving and, in the specific context of his talk, to avoid deflation. He even alluded to running the “printing press” and the “electronic equivalent” to force funds into the economy and financial markets. For a while in this more recent period, that objective seemed to elude the Fed. Banks failed to lend, and money growth languished. But of late the chairman has gotten his looked-for responses. Federal Reserve statistics show the narrow M1 definition of money has grown at a robust rate of about 11% during the last 12 months and accelerated to about a 15.5% annual rate of advance over the past three months. The broader M2 definition of money expanded at a strong 6.3% rate during the last 12 months and held at a 6.5% annual rate of expansion over the last three months. Banks have begun to lend, too. Overall bank lending has expanded at an annual rate of about 3.5% during the past three months, with the critical commercial and industrial component growing at a 13.7% annual rate.
