South Korea's foreign reserves jumped to a record high in July, the central bank said on August 5, 2013, appearing to support traders' suspicions of dollar-buying intervention by currency authorities last month. The reserves stood at $329.71 billion at the end of July, up $3.27 billion from June, the Bank of Korea said in a statement, attributing the rise to management gains and the appreciation of the euro in July, which the Bank of Korea said was up 1.8 percent against the dollar last month.
