China's foreign exchange reserves climbed by $11.5 billion in December 2025, reaching a total of $3.358 trillion, up from $3.346 trillion in November. This increase represents the sixth consecutive monthly rise and marks the highest level since November 2015, largely due to the continued weakness of the U.S. dollar. During the same period, the yuan depreciated by 1.22% against the dollar, while the dollar itself fell by 1.23% against a collection of other major currencies.
