The Bank of Korea kept its policy interest rate steady on Thursday, as it weighs geopolitical risks against a weakening won and resurgent inflation that point to higher rates ahead. The seven-member monetary policy board at the central bank voted to keep its benchmark interest rate unchanged at 2.50%, as expected by 30 of 32 economists polled by Reuters. The two outliers forecast a rate rise. Governor Shin Hyun Song will hold a press conference at 0210 GMT.
