The Bank of Korea raised it's base rate 25 basis points to 3.25% on June 10th (sorry it's late).
Of more concern to the Korean economy is the Financial Supervisory Services notification to credit card companies that they want them to curtail their debt issuance and marketing expenses. The FSC is threatening weekly inspections and bans on new card issuance should the companies not comply. Korean household debt is running at high levels. Hopefully everyone in Korea has learned from the last credit card crisis.
