NEW YORK, Sept 19 (Reuters) - World stock markets broadly rose for a second straight day on Wednesday, while safe-haven assets such as U.S. bonds and the Japanese yen slipped to multi-week lows on bets the ongoing U.S.-China trade spat would inflict less damage than feared.
European shares gained on trade-sensitive materials and auto stocks, while on Wall Street the S&P 500 and the Dow industrials were buoyed by U.S. bank stocks on the back of higher Treasury yields. The Dow hit its highest since late January.
A drop in Microsoft pressured the Nasdaq and disappointing results in Europe from staffing firm Adecco and home improvement retailer Kingfisher weighed on indexes.
MSCI's gauge of equity markets in 47 countries gained 0.37 percent and the pan-European FTSEurofirst 300 index closed up 0.33 percent to two-week highs.
The big question for investors was whether the rest of the world will rejoin the United States in global synchronized growth or if ongoing trade tensions and tighter monetary policy finally slow the U.S. economy, said Michael Arone, chief investment strategist at State Street Global Advisors in Boston.
"That kind of dilemma is really what investors face and trade seems to be the wild card in all this," Arone said.
Investors were underestimating the boost stocks are gaining from the massive U.S. fiscal policy package that far outweighs any trade penalties that have been put forward, he said.
The repatriation of corporate profits this year is likely to be $700 billion, individual and corporate tax cuts $200 billion and the government has boosted spending by $100 billion, Arone said.
"That's $1 trillion of fiscal stimulus. I think the effects of that continue to be under-appreciated by investors," he said.
On Wall Street, the Dow Jones Industrial Average rose 176.25 points, or 0.67 percent, to 26,423.21. The S&P 500 gained 2.89 points, or 0.10 percent, to 2,907.2 and the Nasdaq Composite dropped 15.44 points, or 0.19 percent, to 7,940.67.
U.S. 10- and 30-year Treasury debt yields hit fresh four-month highs after a report that U.S. homebuilding increased more than expected in August.
Housing starts rose 9.2 percent last month, a positive sign for the housing market which has underperformed the broader economy amid rising interest rates for home loans.
The strong data pushed 10-year U.S. Treasury note yields to a high of 3.092 percent, and 30-year bond yields to a high of 3.248 percent, extending a three-day rise in yields.
The dollar slid against the euro and fell to the lowest in nearly three weeks against the risk-sensitive Australian dollar as the latest U.S.-Chinese trade tensions failed to unnerve investors.
The dollar index, which measures the greenback against a basket of six other major currencies, fell 0.11 percent to 94.532.
The euro rose 0.06 percent to $1.1672 and the Japanese yen fell 0.09 percent versus the greenback at 112.25 per dollar.
U.S. oil futures rose more than $1 a barrel on a fifth weekly crude inventory drawdown and strong domestic gasoline demand amid ongoing supply concerns over U.S. sanctions on Iran.
Brent crude oil held near its highest this year on concerns producers may fail to cover a supply shortfall once the U.S. sanctions take effect in November.
Brent crude futures rose 37 cents to settle at $79.40 a barrel while U.S. crude prices rose $1.27 to settle at $71.12.
Bullion bounced as the dollar weakened, indicating investors are starting to worry about the impact of the U.S.-China trade war on the U.S. economy, luring some buyers back into gold investments.
U.S. gold futures for December delivery settled up $5.40 at $1,208.30 per ounce. (Reporting by Herbert Lash; Editing by Bernadette Baum and James Dalgleish)
