In April 2024, the yen dropped to around ¥160/USD, its weakest level since 1990. This dramatic decline reflects a perfect storm of structural and policy factors. Japan’s ultra-loose monetary policy, an aging economy, and a massive interest rate gap with the U.S. are driving the yen’s prolonged weakness.
Understanding why the yen is so weak requires looking at the complex interplay between interest rates, monetary policy, and Japan’s unique position in the global economy.
Key Takeaways
Japan’s weak currency stems from long-term policy responses to past economic challenges. After the asset bubble burst in the 1990s, the country entered a prolonged period of stagnation and deflation known as the “Lost Decades.” To counteract this, the Bank of Japan (BOJ) implemented ultra-loose monetary policy, including negative interest rates from 2016 to March 2024.
Even after exiting negative rates, Japan’s benchmark interest rate remains low at 0.5%, while the U.S. rate stands much higher at 5.25–5.50%. This wide interest rate gap encourages investors to move capital out of yen and into higher-yielding U.S. assets, putting continuous downward pressure on the yen.
Despite recent rate hikes, the BOJ remains cautious due to Japan’s structural issues—like low wage growth, weak domestic consumption, and an aging population—which make aggressive tightening difficult.
While the weak yen benefits Japan’s exports and tourism, it creates real pain for consumers through rising import costs and worsens inflation without boosting domestic demand. This creates a tough balancing act for policymakers.

Downsides:
The Ministry of Finance and the BOJ have intervened multiple times, spending billions to support the yen. In both 2022 and 2024, Japan spent around $60 billion on FX interventions. These actions provided short-term relief but failed to reverse the downward trend, as the core issue—interest rate differentials—remains.
The BOJ raised rates cautiously to 0.5% by January 2025, the first time in 17 years. Governor Kazuo Ueda signaled willingness to hike further if sustainable inflation and wage growth emerge. However, the BOJ remains cautious, wary of derailing Japan’s fragile recovery. Their gradual pace reflects past experiences and the country’s deep-rooted economic issues.
The yen is likely to stay weak in the near term. Traders should monitor interest rate spreads and central bank signals closely. Volatility will create tactical trading opportunities, especially through yen-based carry trades and options.
Trader Insights:
The yen’s prolonged decline has far-reaching effects on global trade, investment flows, and market sentiment:
Overall, the weak yen amplifies price competition in global trade and may alter monetary policy responses in other countries due to imported inflation or shifting capital flows.
The yen’s continued weakness reflects Japan’s long-standing policy divergence from other major economies, particularly the United States. While exporters and tourists benefit, Japanese consumers face rising costs and shrinking real wages. For traders, yen volatility presents both risks and opportunities.
