NEW YORK, March 29 (Reuters) - Crude oil prices continued to fall on Tuesday as oversupply fears resurfaced, while stocks and the U.S. dollar were little changed ahead of a widely anticipated speech by Federal Reserve Chair Janet Yellen.
Yellen, due to speak at the Economic Club of New York at 12:20 p.m. EDT (1620 GMT), may offer hints on the central bank's latest thinking weeks after the Fed forecast two further interest-rate hikes this year, down from a forecast of four following its December meeting.

"The amount of verbal intervention, which has obviously helped the market greatly over the past two months, combined with a production slowdown in the U.S., has probably taken (oil) as far as it can; now the market really wants to see some action," said Saxo Bank senior manager Ole Hansen.
A preliminary Reuters survey of analysts showed U.S. oil stockpiles measured by the American Petroleum Institute were expected to reach record highs.
