CHICAGO, Jan 20 (Reuters) - A rallying U.S. dollar on Wednesday, pushed soybean and wheat futures, which already were struggling with a bearish fundamental picture, to their lowest levels in more than three months, traders said.

Corn futures fell on a combination of the strength in the dollar and continued pressure from the U.S. Agriculture Department's bigger-than-expected production forecast.

"The dollar is going up and that is pressuring grains, crude oil and gold," said Vic Lespinasse, an analyst for GrainAnalyst.com in Chicago.

Wheat led the way lower, dropping 2.4 percent to its lowest level since Oct. 12.

The strong dollar dampens investor enthusiasm for picking up commodities as a hedge against inflation and makes prices for U.S. wheat relatively more expensive to overseas buyers.

Falling prices for wheat have sparked some buying in recent days, but U.S. wheat was attracting little interest.

At 11:11 a.m. CST (1711 GMT), Chicago Board of Trade March wheat futures were down 12 cents at $4.88-1/2 a bushel.

Soybean prices, which were down 2 percent and trading at their lowest level since Oct. 9, were facing additional pressure because Chinese authorities ordered some big banks to curb their lending for the rest of January.

"China is tightening up, urging their banks not to make loans through the end of the month or longer," Lespinasse said. "So, with China putting the brakes on the perceived overheated economy, that's bearish for commodities, especially beans."

CBOT March soybean futures dropped 19-1/2 cents to $9.44 a bushel.

Excellent soybean crop weather in South America and the huge acreage planted to soy there has led to numerous forecasts for a bumper crop and that contributed to the falling prices.

"From my point of view, the soybean market is moving from a demand-driven bull phase into a supply-driven bear phase as we've had record U.S. production and a big and growing South American crop," said Toby Hassall, an analyst with Commodity Warrants Australia.

There also was a view that China, the world's top purchaser of soy, had covered its needs for the time being and might not be as active a buyer as in the past, Hassall added.

Corn futures dropped for the seventh day in a row after being hammered by last week's bearish USDA crop report.

"You would explain some of the move today with action in the dollar, but the market is also being affected by last week's USDA reports that came as a surprise to a large number of people," Hassall said.

CBOT corn for March delivery was down 6 cents at $3.63-1/4 a bushel. Prices fell to their lowest level since Nov. 2 earlier in the day.

The dollar hit a five-month high against the euro and a one-month high against a basket of currencies on Wednesday on the view that the Republican gain of a U.S. Senate seat may help to reduce the nation's fiscal deficit. Prices at 11:13 a.m. CST (1713 GMT)
