TOKYO (AP) — Asian shares mostly declined Tuesday, despite a rally on Wall Street boosted by easing oil prices, as regional investors still weighed the impact from the recent joint U.S.-Japan currency intervention. Japan's benchmark Nikkei 225 slipped 0.6% to 63,369.85, as the U.S. dollar inched up to 157.63 Japanese yen from 157.18 yen. But any U.S. contribution will probably be constrained by size," a report by BMI, a unit of Fitch Solutions, said. On Wall Street, share prices rallied Monday after easing oil prices helped calm worries that inflation could get even worse. In energy trading in Asia early Tuesday, benchmark U.S. crude gained 50 cents to $80.84 a barrel.
