NEW YORK, March 31 (Reuters) - Oil and global stocks rose on Tuesday as investors shrugged off a raft of gloomy economic news and swelling crude inventories to drive major U.S. and world equity indexes to their best monthly percentage gains since at least 2002.
The U.S. dollar rose to a more than a three-week high versus the yen as surging stocks worldwide and weak economic data out of Japan dampened safe-haven flows into the Japanese currency.

The Dow rose 7.7 percent and the broad S&P 500 added 8.5 percent in March, their best monthly percentage gains since October 2002. But uncertainty about economy left the Dow down 13.3 percent and the S&P down 11.7 percent for the quarter.
