The BIS is the doyen of world’s financial institutions, created in Basel in 1930 to clean up the mess left by German reparations payments under the Versailles Treaty. It has since evolved into the bank of central banks, and lately the bastion of monetary orthodoxy. It issued a crescendo of warnings in the build-up to the Lehman crisis, implicitly rebuking the US Federal Reserve and others for holding interest rates too low, which in their view robs economic growth from the future.
