Japan Intervenes

Japan intervened on April 30, 2026, buying yen and selling dollars, lifting it about 3%.

Summary

Traders Cut Odds

Traders cut odds of a Bank of Japan (BOJ) rate hike to below 50%, down from 68% last week.
JPMorgan strategist Ikue Saito says intervention likely before the dollar-yen reaches 162.
Goldman Sachs strategist Karen Reichgott Fishman warns a move toward 163-164 would raise intervention odds.
UBS strategists link the yen’s slide to higher oil prices, a BOJ outlook, and a drop to 160.47 per dollar, its weakest since mid-2024.

History

Historical Context

In the 1970s Japan feared export loss from a strong yen, prompting frequent FX interventions, a pattern amplified after the 1985 Plaza Accord drove the yen from ¥239 to ¥128 per dollar. The October 1998 $10 billion Ministry of Finance-Bank of Japan sell-off halted a slide to ¥147, and today Finance Minister Satsuki Katayama warns the yen near ¥155 may trigger another swift response.
