This week, I seem to have been focused on central banking this week, which is not my favourite topic, but is all the rage over the last several days given the decision of the Bank of Japan to use negative interest rates on any new bank reserves and then continue to pump reserves into the system via its so-called QQE policy (swapping public and corporate bonds for bank reserves), and then imposing a tax on the reserves so created. Crazy is just one euphemism which comes to mind. So still on that theme and remembering that the Bank of Japan explicitly stated that the combination of QQE and the tax on reserves (they call it a negative interest rate – same thing) was introduced to increase the inflation rate back up towards its target of 2 per cent per annum, I thought the following paper was interesting. The paper from the Research Division of the Federal Reserve Bank of St Louis (published July 2015) – Current Federal Reserve Policy Under the Lens of Economic History: A Review Essay – considers the unconventional monetary monetary policy interventions taken by the US Federal Reserve Bank between 2007 and 2009 and comes to the conclusion that “there is no work, to my knowledge, that establishes a link from QE to the ultimate goals of the Fed inflation and real economic activity”. Maybe the Bank of Japan and the ECB bosses should sent this researcher an E-mail and request his evidence. They don’t seem to have been able to escape from the straitjacket of their neo-liberal Groupthink.
