USD/JPY Carry Trade in Focus as AI Capex Boosts Risk Appetite

The yen's role as the world's preferred funding currency is back in the spotlight following Nvidia's earnings beat and the accompanying AI capex optimism spreading across chipmakers like Marvell. Low borrowing costs in Japan continue to subsidize leveraged bets on higher-growth dollar assets, keeping USD/JPY firm.

This dynamic works until volatility spikes. Marvell's stock slide despite raised guidance shows investors are becoming more selective about AI-linked names, a reminder that sentiment shifts can be abrupt and could quickly reprice carry positioning.

Traders should watch equity volatility gauges alongside USD/JPY price action, since any disorderly unwind in tech shares tends to trigger simultaneous yen short-covering, amplifying moves in the pair beyond what fundamentals alone would suggest.
