Summary

Japan Boosts Yen

Japan deliberately executed yen-buying trades during Golden Week’s thin liquidity to boost their effect.
BOJ data show the intervention cost about $67 billion, roughly ¥5 trillion in early May and ¥35 billion on April 30.
Treasury and other funds recorded a ¥4.51 trillion shortfall for the holiday week, far exceeding the expected surplus.
Mimura said IMF free-float rules do not limit Japan’s intervention frequency, while analysts note China and South Korea acted, hinting at coordination.

Summary

Mimura Warns Volatility

Atsushi Mimura, Japan’s top currency diplomat, said authorities are targeting all angles against speculative moves.
He said speculation tied the yen’s 1.8% rise to crude-oil futures but gave no confirmation of oil-driven action.
Mimura declined comment on whether the Finance Ministry defends a specific rate, stressing a focus on curbing volatility.
He warned that after Golden Week, returning liquidity could make it harder to influence yen levels.

Summary

Monex Warns

Monex Group expert director Jesper Koll says domestic investors are pulling money out of Japan because real interest rates stay negative.
Senior economist Carlos Casanova of UBP warned that the Bank of Japan’s cautious tightening and the Ministry of Finance’s aggressive yen-stabilisation create a growing policy dilemma.
Analysts liken yen-market intervention without monetary-policy change to tapping the brake while holding the accelerator, saying the tactic may soon wear out.

History

Historical Context

The 1985 Plaza Accord, signed by the United States, Japan, West Germany, France, and the United Kingdom, forced coordinated currency realignment. Following the pact, Japan’s yen surged from ¥240 per dollar to ¥128 by 1988, a roughly 47 % appreciation that shocked markets. Today, Tokyo’s $35 billion yen-buying operation mirrors the Plaza strategy, with Finance Minister Atsushi Mimura coordinating with U.S. Treasury Secretary Scott Bessent to curb speculative swings. The precedent suggests that repeated interventions without broader monetary reform may only delay volatility, echoing the 1980s lesson that coordinated policy, not isolated trades, stabilizes exchange rates.
