The dollar was steady at slightly lower levels against other major currencies in a quiet day for economic data and ahead of US Fed chairman Alan Greenspan's testimony to the Joint Economic Committee of Congress Thursday. Greenspan's views on the US economy will be central for interest rate expectations and may well have strong implications for the dollar. Some analysts think Greenspan will be more hawkish than other Fed officials recently and will point to the sharp increase in unit labor costs but yet others think he will signal that the hiking cycle will end soon. The Fed has raised its key Fed funds rate from 1 pct to 3 pct over the last year and as things stand, is still widely expected to continue raising the cost of borrowing in a measured manner over the coming months. When the US benchmark US Fed funds rate hits 3.25 pct or 3.50 pct, the Fed may not be able to stick to its current policy of hiking rates in a measured manner, said Divyang Shah at IDEAglobal.com.The Fed may "choose to make further moves data dependent," he added.The dollar will also face another test Friday when US trade numbers for April are released. Any deterioration will weigh on the dollar especially if Greenspan also hints at a pause in US rate hikes.
