US and Japan Launch First Joint Yen Intervention Since 2011

The United States and Japan confirmed on Monday their first joint intervention in currency markets since 2011, a coordinated effort to support the struggling yen after it recently hit 40-year lows against the dollar. The move follows Japan's unilateral action last week and signals a more forceful, unified stance from the two economic powers to stabilize the exchange rate.

Details of the Intervention

According to a Reuters report, the joint action on Friday involved Japan selling almost $60 billion to purchase yen. The United States is expected to contribute between $5 billion and $10 billion to the effort. Both governments have pledged to repeat the action as necessary to counter excessive volatility.

To avoid disrupting the U.S. bond market, the intervention reportedly utilized a Federal Reserve repo facility. This allows Japan to use its vast holdings of U.S. government bonds as collateral to raise the necessary dollars, rather than liquidating the Treasuries outright, which could have caused a spike in U.S. bond yields.

Market Impact

The coordinated intervention has provided a significant, albeit potentially temporary, boost to the Japanese currency. The yen strengthened on the news, briefly touching its best levels against the dollar since early May. Since Japan's initial solo intervention on Thursday, the yen has gained approximately 4% against the U.S. dollar.

This action comes at a critical time, following a decision by the Bank of Japan last week to delay another interest rate increase and ahead of a potential rate hike by the U.S. Federal Reserve next month. The divergence in monetary policy has been a primary driver of the yen's weakness.

Broader Context

Beyond the currency markets, other developments are influencing investor sentiment. Oil prices fell over 5% to below $84 per barrel on news of potential new talks between the U.S. and Iran. Meanwhile, the U.S. corporate earnings season continues to show remarkable strength.

According to LSEG data, aggregate S&P 500 profit growth for the second quarter is tracking at an exceptional 47% year-over-year, nearly double the forecasts from a month ago. This robust earnings backdrop, driven by technology and banking sectors, is helping to explain the resilience of U.S. equity markets despite global economic crosscurrents.
