Latin American equity markets climbed Thursday, fueled by a climb in prices for commodities and a surge on Wall Street on optimism that the U.S. economy may be on track for recovery.

Argentina's Merval gained 3.4% to 1,148.90, its best closing level since Feb. 9.

There, shares of oil firm Petrobras Energia (PZE) rose 2.7%, locally listed shares of Petroleo Brasileiro gained 1.2%, and Tenaris (TS), maker of steel tubes used in the oil industry, rose 3.1%.

The price gains came as crude-oil prices advanced 3% to $54.35 a barrel on the New York Mercantile Exchange, winning back its losses from the previous session after U.S. crude inventories hit a 16-year high.

Metals prices jumped as well. May copper gained 2.9% to $1.855 a pound, and silver for May delivery rose 1.4% to $13.62 an ounce.

Resource prices caught a higher bid with anticipation for a pick up in demand for goods, such as industrial metals and natural resources, after a report showed the fourth-quarter U.S. economic activity shrank by a smaller-than-expected margin.

Gross domestic product contracted at a 6.3% seasonally adjusted rate, the Commerce Department reported. Economists polled by MarketWatch had expected a 6.7% decline.

Commodities prices also found support from comments by China's top central banker that economic growth in the country is recovering, in part because of its $585 billion stimulus plan. China is a key consumer of commodities.

On Wall Street, the Dow Jones Industrial Average rose 2.3% to 7,924.56, and the tech-heavy Nasdaq Composite Index (RIXF) jumped 3.8% as it moved into positive territory for 2009.

The S&P 500 Index finished 2.3% higher at 832.86.

"Given the tremendous amount of bad news priced into U.S. equities, we think recent tentative signs of economic stabilization coupled with greater regulatory visibility have increased investor confidence, [and average earnings per share] will be improving by year-end," Alec Young, equity strategist at S&P Equity Research Services, said in a note Thursday.

He also cautioned that the S&P index's ability to "maintain its upward bias will hinge on continued improvement in the economic and regulatory news-flow."

Brazil, other markets higher

Brazil's Bovespa rose 1.9% to 42,588.66, finding strength from steel stocks, including a 7.4% surge in shares of Gerdau (GGB) and an 8.6% rise in Usiminas.

Vale (RIO), the world's largest provider of iron-ore, a key component in steel production, rose 2.2%.

Shares of oil giant Petrobras (PBR) slipped 0.2%, but were headed toward a more-than-4% gain on a weekly basis. Meanwhile, a labor strike against Petrobras stretched through a fourth day, although the company said the action hasn't hurt production significantly.

Mexico's IPC index rose 1.3% to 20,542.25. Chile's IPSA rose 0.2% to 2,550.82
