USD/JPY longs and Treasury shorts build as traders fade Bessent policy stance

Positioning data and market commentary point to a growing consensus trade that fades US Treasury Secretary Scott Bessent's policy framework, built around short US Treasuries and long USD/JPY exposure. The structure reflects expectations that heavy Treasury issuance and persistent fiscal deficits will keep upward pressure on long-end US yields, widening the US-Japan rate differential that has historically driven USD/JPY higher. The trade also reflects scepticism among institutional macro desks about the administration's ability to engineer lower borrowing costs while maintaining expansionary fiscal policy. Risks to the position are two-sided: a hawkish shift from the Bank of Japan or Japanese Ministry of Finance intervention would compress the differential and trigger sharp USD/JPY downside, while any dovish repricing at the Federal Reserve would undercut the yield support. Traders running this theme should size for elevated volatility around Treasury auctions, US CPI releases and BoJ meetings, and monitor whether crowded positioning creates squeeze risk if long-end yields stabilise or reverse lower.
