On Friday (January 29, 2016), the Bank of Japan issued a seven-page document – Introduction of “Quantitative and Qualitative Monetary Easing with a Negative Interest Rate” – which left me confounded. Do they actually know what they are doing or not? For years, the liquidity management conducted by the operations desk at the Bank has been impeccable, in the sense that they have maintained near zero interest rates in the face of growing fiscal deficits. There was always some doubt when they were the early users of quantitative easing which many claimed was to provide the banks with more reserves so that they would increase their lending to the private domestic sector in order to stimulate growth, after many years of rather moderate real performance to say the least. Of course, banks are not reserve constrained in their lending so the the only way that this aspect of ‘non-conventional’ monetary policy would be stimulatory would be if investment and purchasers of consumer durable were motivated to borrow at the lower interest rates that the asset swap (bonds for reserves) generated. The evidence is that the stimulus impact has been low and that there are many other factors other than falling interest rates governing whether borrowers will approach their banks for loans. In their latest announcement, the logic appears to be that by reducing reserves they will induce banks to lend more. Go figure that one out!
