Bank of Japan pumps another $37bn to ensure market calm
Japan has already injected $98 billion.
"Japan could borrow. However, with a debt-to-GDP ratio of some 200 percent, or twice as bad as that of the United States, and with the main credit rating agencies exercising more scrutiny than before the Credit Crunch, raising funds will be difficult at an economic rate of interest. Moreover, Japan will likely be spending a large chunk of its foreign exchange reserves to buy oil to replace its lost nuclear power generating capacity - diminishing its collateral in the eyes of creditors.
Japan could follow the US example and "paper over" its problems. But without the benefits of being the international reserve currency, the Japanese would immediately feel the effects of domestic inflation. The Bank of Japan has already pumped out ¥8 trillion ($98 billion) in the wake of the earthquake, but it is unlikely to try to match the Fed's $600 billion printing spree this quarter.
So, if Japan is limited in its ability to borrow or print money, it may have to sell part of its vast holdings of US Treasuries."
