(Adds analyst comment; updates prices) BEIJING, June 13 (Reuters) - Base metals prices fell on Wednesday, led by Shanghai aluminum, which touched a six-week low, as investors fretted over liquidity in China and awaited news from the U.S. Federal Reserve's policy meeting. The Fed is expected to raise interest rates at its meeting. Higher rates usually cause the dollar to strengthen, which would make dollar-denominated metals more expensive for holders of other currencies and could weigh on prices. Helen Lau, an analyst at Argonaut Securities in Hong Kong, said Shanghai metals prices were all falling because of a lower-than-expected social financing figure in China amid an intensified crackdown on the country's shadow banking sector. "Markets are worried about whether there would be liquidity," Lau said. China's total social financing (TSF), a broad measure of credit and liquidity in the economy, dropped sharply to 760.8 billion yuan ($118.80 billion) in May from 1.56 trillion yuan in April, central bank data showed on Tuesday.
