China’s foreign exchange reserves fell for a sixth straight month in December to the lowest since early 2011, but held just above the critical $3 trillion level, as authorities stepped in to support the yuan ahead of U.S. President-elect Donald Trump’s inauguration. Reserves fell by a slightly less than expected $41 billion last month to $3.011 trillion, central bank data showed on Saturday, following a drop of $69.06 billion in November.
