Japan's Currency Weakens Despite High Interest Rates

The Japanese yen has recently reached its highest level in 19 months against the Korean won, despite interest rates rising to their highest level in decades. This phenomenon is contrary to common sense, as a country's currency typically becomes stronger when interest rates rise.

According to Shinhan Bank Economist Baek Seok-hyun, Japan's interest rate hike is not entirely 'good' due to the government's enormous debt and expansionary fiscal policy. The country's government debt is over twice its GDP, making it difficult for the central bank to raise interest rates further without increasing the government's burden.

The Bank of Japan faces a dilemma in balancing monetary policy with fiscal control. Raising interest rates could strengthen the yen, but it would also increase the government's interest burden. Conversely, expanding bond purchases to prevent rising government interest rates would undermine the central bank's ability to tighten policy.
