Most of the time nobody notices the credit flowing through the lungs of the economy, any more than people notice the air they breathe. But everyone knows when credit stops circulating freely through markets to banks, businesses and consumers. For almost a year the markets had worried about banks’ liquidity and solvency. After the bankruptcy of Lehman Brothers last month, amid confusion about whom the state would save and on what terms, they panicked. The markets for three-, six- and 12-month paper are shut, so banks must borrow even more money overnight than usual.
Banks used to borrow from each other at about 0.08 percentage points above official rates; on September 30th they paid more than four percentage points more. In one auction to get dollar funds overnight from the European Central Bank, banks were prepared to pay interest of 11%, five times the pre-crisis rate. Astonishingly, rates scaled these extremes even as the Federal Reserve promised $620 billion of extra funding.
Bankers have always earned their crust by committing money for long periods and financing that with short-term deposits and borrowing. Today, that model has warped into self-parody: many of the banks’ assets are unsellable even as they have to return to the market each day to ask for lenders to vote on their survival. No wonder they are hoarding cash.
This is why those politicians who set the interests of Main Street against those of Wall Street are so wrong. Sooner or later the money markets affect every business.
