NEW YORK, March 12 (Reuters) - Stocks around the world rose for a rare third day in a row on Thursday on reassuring U.S. retail sales and gold jumped after Switzerland intervened in currency markets, heralding a possible beggar-thy-neighbor policy war.
Oil jumped more than 6 percent and helped lift energy shares on both sides of the Atlantic as strong loan data from China led investors to speculate it could spur global growth.
The Swiss move to head off deflation by devaluing its currency is the first by a big central bank. Analysts said it could push the European Central Bank to follow the "unconventional easing" measures of the U.S. Federal Reserve and Bank of England. For details, see [
]The franc fell in its biggest one-day drop ever against the euro, as the intervention and interest rate cut by the Swiss National Bank went far beyond what analysts had expected.
The U.S. dollar rose against the euro and yen, while euro-zone government bonds shot higher after the Swiss central bank signaled it stood ready to buy fixed-income assets.
The intervention suggested one of the world's safest currencies was deliberately undermined to help boost growth, which could lead other countries to follow.
"If all currencies are being devalued against each other then gold is a currency which is going to profit from it," Commerzbank analyst Eugen Weinberg said in Frankfort.
Mark Chandler, a senior currency strategist at Brown Brothers Harriman in New York, said the intervention raised questions, even though it enjoyed immediate success.
The Swiss move comes ahead of a gathering of finance chiefs from the Group of 20 rich and developing economies near London this weekend that will likely include calls to avoid protectionism, often cited as a contributing factor in the Great Depression .
"It is troubling that a country with a current (account) surplus larger than 10 percent of GDP feels compelled to depreciate its currency," Chandler said.
U.S. stocks rallied about 2 percent, spurred by a slight dip in U.S. retail sales in February that suggested consumer spending may be stabilizing. [
]"Investors psychologically are at a crossroads. We've seen a significant rally for the past couple of days. I think investors in general are wondering if this is a false start or a real-deal type rally," Michael Koskuba, a portfolio manager at Victory Capital Management.
"The other question is, did we hit a bottom?" Koskuba said.
