Traders bet on renewed volatility in the yen after intervention

Two weeks after a joint US-Japan intervention aimed at stabilizing the yen, traders are increasingly betting on further moves as the dollar hovers around ¥159; the carry-trade dynamic—funding high-yield bets with cheap yen—keeps yen under pressure, aided by high US yields and cautious BOJ policy. While intervention may have slowed the slide for now, a disorderly unwind remains a market risk that could ripple through US tech and EM assets, so policymakers face a delicate balance.
