TOKYO, March 25 (Reuters) - Asian shares extended their rally on Wednesday in the wake of Wall Street's big gains as U.S. Congress appeared closer to passing a $2 trillion stimulus package to curb the coronavirus pandemic's economic toll.
MSCI's broadest index of Asia-Pacific shares outside Japan rose 1.3% with Australian shares rising 4.5% and South Korean shares gaining 4.0%. Japan's Nikkei added 2.0%.
"Japanese shares have been bolstered by aggressive buying from the Bank of Japan and pension money this week. That has prompted hedge funds to cover their short positions," said Norihiro Fujito, chief investment strategist at Mitsubishi UFJ Morgan Stanley Securities.
On Tuesday, MSCI's gauge of stocks across the globe gained 8.39%, the largest single-day gain since the wild swings seen during the height of the global financial crisis in October 2008.
On Wall Street, the Dow Jones Industrial Average soared 11.37%, its biggest one-day percentage gain since 1933.
U.S. stock futures were down 0.5% in early Asian trade.
Senior Democrats and Republicans in the divided U.S. Congress said on Tuesday they were close to a deal on a $2 trillion stimulus package to limit the coronavirus pandemic's economic toll. But it was unclear when they would be ready to vote on a bill.

Gold soared almost 5%, its biggest gains since 2008, on Tuesday and last stood at $1,633, in part helped by concerns lockdowns in major producer South Africa could disrupt supply.
Still, the course of the market is still largely dependent on how much countries can slow the pandemic and how quickly they can lift various curbs on economic activity.

Oil prices steadied as hopes for U.S. stimulus offset fears from falling global demand.
