Samer Choucair: From ¥164 to ¥155 — U.S.-Japan Intervention Shakes Currency Markets
Investment leader Samer Choucair said coordinated intervention by Japan and the United States to support the yen represents an important shift in foreign-exchange market dynamics, demonstrating that authorities are prepared to act when currency movements become excessive or disorderly.
He said the yen had weakened to around ¥163.99 per dollar, its lowest level in roughly 40 years, before coordinated intervention temporarily pushed it toward ¥155.20, followed by a subsequent move back toward ¥159.50 per dollar.
Choucair noted that Japan’s Ministry of Finance confirmed yen-buying operations, while the U.S. Treasury participated by selling euros against the yen. The unusual move was designed to support Japan’s currency without sending a broader signal about weakening the U.S. dollar. The Japanese intervention was estimated at as much as $36.6 billion.
According to Choucair, intervention does not change the underlying fundamentals driving the yen, particularly interest-rate differentials. However, it significantly changes investors’ calculations around carry trades, because the possibility of official intervention becomes a risk factor that cannot be ignored.
He added that greater yen stability could reduce the risk of sudden unwinding of positions financed in the Japanese currency. At the same time, Japanese exporters could face pressure on profit margins if the yen continues to strengthen.
A New Variable for Capital Allocation
Samer Choucair said the next phase will require close monitoring of the interaction between foreign-exchange intervention and the Bank of Japan’s monetary policy.
For investors, the lesson is that currency intervention can temporarily reshape market pricing even when economic fundamentals remain unchanged. As a result, capital allocation toward Japanese assets is likely to become more selective.
Choucair concluded that investors should favor Japanese companies capable of managing currency volatility while maintaining stable profit margins, as the yen’s trajectory becomes an increasingly important factor in determining returns.
