Asian stocks began the new quarter on Monday with mild gains following a strong performance by global equities last week, while the dollar held steady ahead of key economic indicators.\u00a0MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.3 percent. South Korea's KOSPI gained 0.6 percent and Japan's Nikkei advanced 0.55 percent. Hong Kong's Hang Seng added 0.25 percent and Shanghai was up 0.4 percent.\u00a0Wall Street surged last Thursday as technology stocks rebounded,\u00a0 ending a tumultuous first quarter on a high note. Many major financial centres were closed for the Good Friday Easter holiday. MSCI's world equity index ended up 1.2 percent last week. But it lost about 1.5 percent in the first quarter, pushed away from record highs as tensions over global trade escalated, turmoil in the White House deepened and market-leading technology firms wobbled on fears of regulation and other issues.\u00a0"We expect strong and broad-based growth to continue globally," wrote strategists at Barclays. But they warned that there were looming risks: "Trade protectionism, U.S. economic policy uncertainty, concerns about higher cross-market volatility and risk premium in core rates markets call for a more tactical approach to risk assets."\u00a0While fears of an all-out global trade war that gripped the financial markets last month have abated somewhat, tensions between the United States and China over tit-for-tat tariffs kept investors on edge. China on Monday imposed extra tariffs on U.S. products including frozen pork, wine and certain fruits and nuts in response to U.S. duties on imports of aluminium and steel.\u00a0In currencies, the dollar was steady at 106.340 yen, while the euro was almost unchanged at $1.2327. The greenback had gained about 0.6 percent against a basket of six major currencies last week helped by a combination of factors including perceived progress on North Korea issues.\u00a0The dollar index still lost more than 2 percent last quarter, marking its fifth straight quarter of declines. "A list of important indicators will be released this week, which could help steady market sentiment even though U.S.-China trade concerns and other geopolitical risks continue to linger in the background," said Koji Fukaya, president at FPG Securities in Tokyo. U.S. data due this week include Monday's Institute for Supply Management (ISM) manufacturing index, Wednesday's ISM non-manufacturing index and the non-farm payrolls report on Friday.\u00a0Crude oil prices extended gains, lifted by a drop in U.S. drilling activity as well as by expectations that the United States could re-introduce sanctions against Iran. U.S. drillers cut seven oil rigs in the week to March 29, bringing the total count down to 797. It was the first time in three weeks that the rig-count fell.\u00a0U.S. crude futures rose 0.4 percent to $65.21 a barrel and Brent advanced 0.55 percent to $69.73 a barrel.\u00a0"Investors took their cue from falling U.S drilling counts," Wang Xiao, head of crude oil research with Guotai Junan Futures said.\u00a0"But increasing trade friction between China and U.S. is likely to rock global markets and tarnish bullish sentiment in crude oil markets."
