Bombardment of Yeonpyeong
The North Korean attack had a global impact on the financial markets. Several Asian currencies weakened against the euro and U.S. dollar, while at the same time Asian stock markets declined. The impact of the shelling on the financial industry led South Korea's central bank, the Bank of Korea, to hold an emergency meeting to assess the impact of the fighting on the markets.
