Japanese Yen Weakens as Earthquake and Tsunami Strike, Oil Prices and Policy Uncertainty Add Pressure

Bearish (-0.6)Impact: High

Published on April 20, 2026 (3 hours ago) · By Vibe Trader

The Japanese Yen (JPY) experienced notable weakness on Monday, with the USD/JPY pair trading 0.25% higher near 159.00 and the EUR/JPY holding gains around 187.00 during the European session [1][2]. This decline in the Yen followed a series of natural disasters in Japan, including a significant earthquake off the east coast of Honshu, reported at magnitude 7.3 by one source [1] and 7.5 by another, which struck the Tohoku region at 4:53 p.m. Monday [2]. The Japan Meteorological Agency issued an immediate tsunami warning for Hokkaido, Iwate, and Aomori prefectures, forecasting waves up to three meters [2]. NHK confirmed that a tsunami was observed off the Japanese coast [1]. Despite the seismic activity, Hokkaido Electric Power reported no abnormality at the Tomari nuclear power plant [1], while Tohoku Electric Power was still assessing the impact on its Onagawa nuclear facility [2].

The Yen's underperformance was further exacerbated by rising oil prices, attributed to renewed tensions between the United States and Iran, which have heightened concerns over Japan’s reliance on Middle East oil imports [2]. Iran's foreign ministry spokesperson stated there are "no plans for a second round of negotiations with the United States for now" [1], and Iranian state media reported that Tehran refused to resume talks due to "unrealistic expectations" [2]. Additionally, Iran has blocked the Strait of Hormuz, reversing a brief reopening after US President Donald Trump refused to lift port blockades [2]. This blockade has dampened optimism for normalized energy supply from the Middle East, fueling stagflation concerns in the Eurozone [2].

On the monetary policy front, investors remain uncertain about the Bank of Japan's (BoJ) next move. While there are doubts about a rate hike at the upcoming April 28 meeting, the BoJ is expected to revise up its inflation forecasts due to elevated energy costs [1][2]. BoJ Governor Kazuo Ueda has avoided signaling an April hike [2], and the negative energy shock has raised concerns over Japan’s economic outlook [1]. Meanwhile, the US Dollar Index (DXY) traded 0.1% higher near 98.30, reflecting improved safe-haven demand for the Greenback amid geopolitical tensions [1].

In Europe, the Euro may find support as traders anticipate potential interest rate hikes by the European Central Bank (ECB) later this year. ECB President Christine Lagarde acknowledged that elevated energy costs are pushing the Eurozone away from its baseline growth path but did not signal imminent rate hikes [2].

Looking ahead, US investors are awaiting the confirmation hearing of President Donald Trump’s nominee, Kevin Warsh, for Federal Reserve Chairman, with markets expected to scrutinize his views on monetary policy amid de-anchored inflation expectations and higher oil prices [1].

CONCLUSION

The Japanese Yen's decline was driven by a combination of natural disasters, rising oil prices, and ongoing uncertainty over monetary policy. Geopolitical tensions between the US and Iran further pressured the Yen and global markets. Investors remain cautious as they await key central bank decisions and developments in the energy sector.
