The Aftermath of U.S. Interest Rate Hikes and 'Yen-carry trade' Risks... What is the Economic Direction for South Korea and Japan?

The trend of interest rate hikes in the United States and the resulting changes in global capital flows are acting as complex variables for Asian economies, including South Korea and Japan. Through a recently released video, economic master Dr. Gwak Su-jong warned of the justification for U.S. interest rate hikes and the risks of the 'Yen-carry trade' that may arise in the process.

Pressure for U.S. Interest Rate Hikes and the Embers of 'Yen-carry trade'

According to the video, the United States is in a situation where it may implement interest rate hikes in September ahead of the November midterm elections. The speaker cited the prevention of the 'reverse yen carry trade' as one of the main justifications the United States is considering for raising interest rates. Mentioning the case in August 2024 where stock prices plummeted by more than 20% due to the aftermath of the Yen-carry trade liquidation, he explained that if Japan raises interest rates, the United States may also face pressure to raise interest rates. The analysis suggests that if rapid capital movement occurs during the process of withdrawing Japan's low-interest funds, it could become a risk factor like a 'dormant volcano' that could shake the market at any time.

Additionally, the debt issue of the United States economy was pointed out as a major variable. The speaker presented a forecast that the scale of U.S. debt has exceeded 40 trillion dollars and will reach 120% of GDP in the 2030s. He mentioned that such massive debt and the liquidity released into the market could ultimately become factors that increase the volatility of asset values.

Common Challenges and Uncertainties for South Korean and Japanese Economies

Interest rate hikes and exchange rate fluctuations are presenting common challenges to the economies of South Korea and Japan. Using the case of Japan, the speaker explained the possibility of a vicious cycle where rising import prices trigger inflation, which in turn leads to pressure for interest rate hikes. In particular, noting that many products consumed within Japan are made in China, he analyzed that the correlation between import costs and exchange rates has a significant impact on prices.

The South Korean economy is also not free from the influence of exchange rate fluctuations. The speaker pointed out the gap between the impact of a falling exchange rate on corporate profitability (foreign exchange losses) and the price burden felt by the public. Amidst such economic uncertainty, issues such as deepening polarization and consumption polarization due to extreme aging were presented as major challenges the South Korean economy will face in the future. Furthermore, he predicted that how the South Korean government and economic agents equip themselves with responsiveness amidst the rapidly changing industrial environment—such as the competition for leadership in the AI industry and China's technological pursuit—will be the key factor determining the future economic direction.
