HONG KONG, Oct 22 (Reuters) - Asian stocks fell on Wednesday as poor U.S. corporate results and falling commodity prices fanned worries of a protracted global economic slowdown.
The U.S. dollar rose to a 20-month high against the euro as investors bet that central banks around the world will have to catch up to this year's deep interest rate cuts by the Federal Reserve as their economies slow.
In addition to problems created by tight credit markets, some Asian companies have been caught off guard by the pace at which global demand has dropped. As a result, rising inventories pose yet another drag on earnings prospects.
"As the credit crunch has worsened, wholesale business inventories have risen, causing an alarming rise in inventories in Asia and emerging markets at a time when seasonally these are usually being drawn down," said Sean Darby, chief Asia strategist with Nomura in Hong Kong.
"We would expect earnings to be further revised down within Asia and global emerging markets," he said in a note.

The most dominant market trend since the financial crisis began, particularly in the last month, has been a broad process called de-leveraging, by which investors cut down on their debt-financed positions and sell liquid assets for cash or to pay off losing strategies.
Of the many markets affected by this process, the equity and commodity markets have been hard hit.
