I continue to be completely puzzled that somebody would think that central banks somehow have run out of ammunition and that monetary policy is impotent. The developments in the global financial markets since August-September last year clearly tell you that monetary policy is extremely potent – also when interest rates are at the Zero Lower Bound.
Just take a look at this story from Japan today:
Japanese shares rose, with the Nikkei 225 Stock Average heading for the highest close since September 2008, as the yen fell after Bank of Japan Governor Masaaki Shirakawa said he will step down ahead of schedule.
…The Nikkei 225 gained 3 percent to 11,377.53 as of 12:38 p.m. in Tokyo, heading for the highest close since Sept. 29, 2008, two weeks after the collapse of Lehman Brothers Holdings Inc. Volume today was 48 percent above the 30-day average. The broader Topix Index advanced 2.8 percent to 966.03, with eight stocks rising for each that fell.
…The Topix has surged 34 percent since elections were announced on Nov. 14 on optimism a new government will push for aggressive stimulus. The gauge is trading at 1.14 times book value, compared with 2.1 for the Standard & Poor’s 500 Index and 1.45 for the Stoxx Europe 600 Index.
(Update: Nikkei is actually up 4%!)
And from another story:
The yen slid to its weakest level in almost three years against the dollar and euro on speculation Japan’s government will hasten the selection of a new central bank chief to take further steps to end deflation.
Japan’s currency added to yesterday’s biggest drop versus the euro in more than a week after Bank of Japan Governor Masaaki Shirakawa said he will step down on March 19, almost three weeks before his term is due to end. Demand for the 17- nation euro was supported on prospects the European Central Bank will refrain from easing monetary policy tomorrow. The Australian dollar slid after data showed the nation’s retail sales unexpectedly fell in December.
Financial markets are the best indicators of the monetary policy stance we have – a surging Japanese stock market and much weaker yen is a very strong indication that Japanese monetary conditions are getting decisively easier. Easier monetary conditions mean higher Japanese nominal GDP – just wait and see.
The market action in the Japanese markets this morning is yet another extremely clear demonstration of the Chuck Norris effect – that monetary policy does not only work through “printing money”, but also through expectations. As Scott Sumner likes to say – monetary policy works with long and variable leads. Said in another way a new Bank of Japan governor has not even been appointed but he is already easing monetary conditions in Japan as Mark Carney is in the UK.
And to all you Keynesian fiscalists out there I challenge you to find me one single example of “optimism” about “fiscal stimulus” having moved any major stock market by 4% in a day!
What we are seeing now in the US, Japan and likely soon in the UK is the kind of Rooseveltian Resolve that brought the US economy out of the Great Depression in 1933 after Roosevelt went off the gold standard and trust me – monetary policy does work! In the 1930s the “gold bloc” countries failed to understand that – today it is the ECB – but luckily for Europeans the US and Japan are leading the charge and is pulling us out of this crisis. That is what the global stock markets have been celebrating since August-September. It is really simple.
