US and Japan Launch First Coordinated Currency Intervention Since 2011 to Stabilize Yen
Washington and Tokyo have united to halt the yen's slide after it hit a four-decade low against the dollar. This rare joint action aims to mitigate risks to the global economy and manage rising borrowing costs.
Key takeaways
- Japan and the US conducted their first coordinated currency intervention since the 2011 tsunami to prevent further yen depreciation.
- Tokyo likely spent $59 billion on Thursday, while US Treasury notes suggested a planned contribution of $5 billion to $10 billion.
- The intervention aims to stop Japanese bond sell-offs from driving up global borrowing costs, including for the US government.
- Interest rate disparities remain the primary driver of yen weakness, with Japan at 1% compared to the US Fed's 3.50% to 3.75% range.
- Both nations have pledged to intervene intermittently to deter currency speculators and maintain market order.
Transatlantic Strategy to Counter Market Volatility
For the first time since the 2011 earthquake and tsunami disaster, the United States and Japan executed a coordinated market intervention to shore up the struggling yen. The move follows the Japanese currency's recent collapse to a 40-year low. Both the Japanese Ministry of Finance and US Treasury Secretary Scott Bessent confirmed the action, signaling a commitment to repeated interventions if market instability persists.
Bank of Japan data suggests Tokyo offloaded nearly $59 billion in US dollars on Thursday alone to purchase yen. While the US Treasury has not officially disclosed its specific contribution, a notebook observed in front of Secretary Bessent during a cabinet meeting indicated a planned purchase between $5 billion and $10 billion. President Donald Trump affirmed the partnership on Sunday, stating that the US stands ready to assist Japan in correcting what he described as a substantial undervaluation of the currency.
Strategic Interests and Economic Fallout
The intervention is not merely an act of diplomacy but a calculated effort to protect the global financial system. A continued sell-off in the yen and Japanese government bonds could inadvertently increase borrowing costs for Washington. Shigeto Nagai, head of Japan economics at Oxford Economics, noted that US participation serves its own national interests by providing significant market stability at a relatively low fiscal cost.
Experts expect these coordinated actions to occur intermittently. "Even if the actual amount of intervention is not particularly large, the prolonged sense of vigilance regarding intervention will be effective in deterring speculators," Nagai told the BBC. The psychological impact of two major powers working in tandem is intended to prevent the "disorderly movements" cited by the Japanese finance ministry.
Root Causes of Yen Weakness
The yen’s current vulnerability stems from a stark divergence in monetary policy. While the Bank of Japan recently raised interest rates to 1%—the highest point since 1995—this remains far below the US Federal Reserve's benchmark range of 3.50% to 3.75%. This interest rate gap makes the yen less appealing to international investors compared to the dollar.
Beyond interest rates, Japan’s economy faces deep-seated structural hurdles:
- A multi-decade decline in the working-age population.
- Persistently low industrial productivity levels.
- Heavy dependence on energy imports that must be settled in US dollars.
Following the news of the intervention and remarks from President Trump, the dollar dipped to 157.07 yen, retreating from last month's peak of 164. However, the market remains reactive, with the yen hovering around 157.70 following official statements from Tokyo on Monday.
