US and Japan Intervene to Prop Up Yen as Changan Auto Pauses 3bn Yuan Investment

The Quick Take

• US and Japan conducted second consecutive day of coordinated yen intervention, buying yen near 40-year lows below 163 per dollar.
• Changan Auto halted a 3 billion yuan subsidiary capital injection, shifting to market-based financing that opens the EV unit to external investors.
• IEA reports Japanese electricity spot prices rose 30% year-over-year in Q2 due to ongoing Hormuz Strait blockade effects.

Japan and the United States conducted joint yen intervention for the second consecutive day, with the Japanese government and Bank of Japan buying yen in New York trading hours while the New York Fed, acting on behalf of the US Treasury through Goldman Sachs and Morgan Stanley, sold euros and bought yen. The yen had fallen to its lowest level in approximately 40 years, breaking below the 163 yen per dollar level, triggering the coordinated intervention that marks one of the most significant US-Japan joint currency market operations in nearly three decades. The intervention signals the two governments' tolerance limit for yen weakness has been definitively breached.

The concurrent Changan Auto decision to halt a 3 billion yuan capital injection into its intelligent vehicle subsidiary adds a capital allocation dimension to the Asia Pacific market picture. Rather than injecting funds directly, Changan is transitioning the subsidiary to market-based financing, which implies external investors will now set the terms and valuation for Changan's EV and smart mobility business. This capital structure shift opens the door to broader institutional participation in what has been a captive subsidiary relationship, potentially allowing strategic investors including global automakers to take positions in Changan's intelligent vehicle platform. Meanwhile, the IEA reports Japanese power prices rose 30% year-over-year in Q2 due to the Hormuz Strait blockade affecting liquefied natural gas flows to Japan.

Watch the durability of the yen intervention signal, specifically whether yen holds below the 160 per dollar level in the weeks following the joint operation or retraces toward the intervention-triggering levels. Changan Auto market financing round terms and investor identity will be disclosed in upcoming corporate announcements and will establish a market-based valuation for the Chinese EV intelligent vehicle space. The macro variable that ties all three stories together is global energy supply chain security, as the Hormuz blockade elevates power costs across Japan, pressures the yen through import cost inflation, and accelerates the transition to domestic EV adoption as a policy response to oil import dependence.
