SYDNEY, Jan 24 (Reuters) - U.S. soybean prices edged down for the first time in seven sessions on Wednesday, though prices lingered near a five-week high amid concerns that dry weather in South America will hamper production.
* The most active soybean futures on the Chicago Board of Trade were down 0.1 percent at $9.85-3/4 a bushel by 0159 GMT. They firmed 0.2 percent on Tuesday, when prices hit their strongest since Dec. 11 at $9.88-3/4 a bushel.

* The dollar touched a four-month low against the yen on Wednesday, pressured by simmering concerns that the U.S. currency's yield advantage will start to erode as major central banks head toward unwinding their massive stimulus.
* Oil prices were firm on Wednesday, receiving ongoing support from healthy economic growth as well as from supply restrictions led by a group of producers around the Organization of the Petroleum Exporting Countries (OPEC) and Russia.
* U.S. stocks advanced on Tuesday, as strong results from Netflix helped lift the S&P and Nasdaq Composite, but the Dow Industrials were hemmed in by declines in Johnson & Johnson and Procter & Gamble.
