Amidst the tumultuous economic situation in Japan, there is a growing focus on the interplay between interest rates and exchange rates.
Currently, Japan’s long-term interest rates have reached a high level of 0.84%, while the yield on U.S. 10-year Treasury bonds is approaching 5%.
In this context, the yen is weakening while the interest rate differential is narrowing.
This article explores the complex economic phenomenon by explaining the relationship between rising interest rates, currency exchange rate fluctuations, inflation, and their impact on the Japanese economy.

■ The Interplay of Interest Rates and Exchange Rates
Interest rates and exchange rates are fundamental concepts in economics, and they are closely interrelated.
The value of a currency depends significantly on a country’s interest rate levels, with rising interest rates usually making the currency more attractive and leading to an increase in exchange rates.
Conversely, declining interest rates tend to decrease the value of a currency and lead to lower exchange rates.
Let’s look at a specific example:
while Japan’s long-term interest rate is 0.84%, U.S. 10-year Treasury bonds are approaching 5%, which contributes to the weakening of the yen.
High-interest rates in the U.S. make it attractive for investors, leading to capital inflows into the U.S. As a result, the demand for Japan’s currency, the yen, decreases, causing depreciation.
This interplay is continuously monitored in the currency market and watched closely by investors and government authorities.
Exchange rate fluctuations have a significant impact on import and export businesses, making the dynamics of interest rates and exchange rates critical for the domestic economy.
■ Factors and Consequences of Rising Japanese Interest Rates
Several factors influence the rise in Japanese interest rates.
Interest rates are shaped by central bank policies, economic conditions, and international interest rate levels, and their increase has various impacts on the domestic economy.
Let’s consider some specific factors.
While the rising interest rates in the U.S. contribute to yen depreciation, geopolitical risks such as those in the Middle East are affecting the increase in interest rates.
This means that if interest rates rise more than expected, the yen’s depreciation could intensify.
Japan’s rising interest rates are complicated by uncertain factors, both domestic and international.
How does this rise in Japanese interest rates affect the economy?
Increasing interest rates lead to higher loan interest payments, putting pressure on businesses and individuals.
In this situation, economic slowdown becomes a concern, and the burden on households increases.
With rising interest rates and yen depreciation happening simultaneously, the domestic economy faces a double challenge.
■ U.S. Interest Rate Increases and the Japanese Interest Rate Differential
Interest rate differentials significantly impact currency value, with high-interest currencies becoming attractive for investment.
Typically, a currency from a country with higher interest rates strengthens, promising investors higher interest returns.
This influences the supply and demand dynamics of currencies in the foreign exchange market.
Currently, the U.S. is experiencing rising interest rates, with 10-year Treasury yields reaching approximately 5%.
This is the highest level since 2007 and reflects the U.S. economy’s recovery and increasing inflation risks.
These high-interest rates are promoting yen depreciation, and the narrowing interest rate differential is a concern.
While Japan’s long-term interest rate stands at 0.84%, the U.S. interest rate is approaching 5%, causing the interest rate differential to shrink.
As the interest rate differential narrows, the yen becomes more attractive, leading to increased demand from investors and yen depreciation.
Consequently, import prices rise. As Japan’s long-term interest rate ceiling is set at 1%, the interest rate differential is expanding, and Japan alone might suffer from increased import prices.
■ Impact of Inflation and Economic Conditions
The rising interest rates and yen depreciation are interconnected and have complex effects on inflation and the economy.
Typically, rising interest rates are considered to cool down economic activity, as higher loan repayments constrain both businesses and households.
However, at the same time, increasing interest rates promote yen depreciation, leading to rising import prices.
Japan is currently experiencing simultaneous trends of rising interest rates and yen depreciation, subjecting the domestic economy to a double challenge.
Higher interest rates are constraining business and individual economic activities, leading to concerns of economic cooling.
Simultaneously, yen depreciation is causing import prices to rise, heightening inflation risks.
According to the Teikoku Databank, households are saving an additional ¥3,700 per month, causing financial strain.
In this context, the Japanese economy is under pressure on both the inflation and economic fronts.
To resolve this challenge, the central bank and government authorities are adjusting their policies to stabilize the economy.
■ Challenges of Wage Increases and Real Wages
Wage increases are crucial to counteract inflation and maintain real wages.
However, actual wage increases depend significantly on a company’s economic condition and market competitiveness.
For small and medium-sized enterprises (SMEs), wage increases can be particularly challenging, and the improvement of labor market conditions and business performance is necessary.
The Japanese Trade Union Confederation (Rengo) has set a wage increase target of “5% or more.”
However, there are variations in the implementation of wage increases between large enterprises and SMEs.
While large companies may have room for wage increases, SMEs are facing a tougher situation.
Labor shortages are also a significant challenge for SMEs, and further wage hikes are considered difficult after raising wages.
Ken Kobayashi, the chairman of the Japan Chamber of Commerce and Industry, representing SMEs, stated,
“We want to make efforts to achieve ‘real wage increases (beyond price rises),’ but it’s a bit tough for (SMEs).”
Continuing negative real wages may decrease purchasing power for workers, impacting the economy.
As rising interest rates and yen depreciation continue, challenges have come to the forefront regarding both inflation and economic conditions.
To realize wage increases and maintain real wages, it is necessary to enhance the competitiveness of SMEs and improve the market environment.
The central bank and government authorities are working to adjust monetary and fiscal policies for economic stability, but resolving these challenges will require time and cooperation.
■ Conclusion
As rising interest rates and yen depreciation exert complex effects on the Japanese economy, adjustments are required to achieve economic stability and growth.
Understanding the interplay between interest rates and exchange rates, the factors and consequences of rising Japanese interest rates, U.S. interest rate increases and the Japanese interest rate differential, the impact of inflation and economic conditions, and the challenges of wage increases and real wages is crucial when formulating economic policies.
To address the challenges facing the Japanese economy and achieve sustainable growth, government authorities, central banks, businesses, and workers must cooperate and find adjustment measures.
