Yen at 40-Year Low: Japan Signals Possible Intervention as Currency Weakens
Japan's Finance Minister, Satsuki Katayama, stated on Tuesday (June 30, 2026) that authorities are prepared to take "appropriate action" after the yen fell to a 40-year low against the US dollar. The currency has been under sustained pressure due to the ongoing West Asia conflict and the widening gap between US and Japanese interest rates.
According to local media reports, Katayama said Japan "will take appropriate action at any time as necessary." This statement is widely interpreted as a warning to markets that Japan is ready to intervene to support the yen, following the expenditure of over $70 billion on intervention efforts last month.
The yen weakened past 161.96 per dollar in London trading on Monday (June 29, 2026), a level not seen since 1986. It later traded at 162.17 in Asian markets after dipping to 62.40 earlier in the session.
A weaker yen increases import costs for Japan, which is heavily reliant on imported resources, particularly oil priced in dollars. The government of Prime Minister Sanae Takaichi has been mitigating the impact on consumers through substantial fuel and energy subsidies.
Conversely, the weak yen has boosted tourism by making shopping, accommodation, and food more affordable for foreign visitors.
The Bank of Japan raised interest rates earlier this month to the highest level in 31 years. However, expectations that the US Federal Reserve may also increase borrowing costs this year suggest the interest rate differential will persist. Further rate hikes by the Bank of Japan could encounter resistance from the Takaichi government, which is concerned about stifling economic growth with higher borrowing costs.
