Central Banks Pour The Money

Seeing liquidity crunch because of sub-prime mess in the U.S., central banks of major economies are pouring huge money in the financial system.
Several leading funds of major investment banks and institutions have been closed due to losses that they have incured in sub-prime investments in the U.S.
Yen has been strengthning for the past few days and this is also a cause of concern, critical level to watch out for yen against dollar is 115. This is very important from the yen carry trade point of view as it has in the past and in present providing huge liquidity to the financial markets.
It will also be very interesting to see if Japanese central bank raises the interest rates this time or not, again very important for yen carry trade to keep going.
