## Prediction

Within seven days, the combination of foreign central bank holdings of US Treasuries at 1990s lows and 40-year-high JGB yields will trigger a partial unwind of global carry trades built on cheap yen and low US real yields. Funding currencies like JPY and CHF will appreciate on short-covering, while higher-yield EM FX and risk assets see outflows, especially in countries with large current account deficits. Strategically, this repricing raises global borrowing costs, tightens financial conditions, and limits fiscal space for governments trying to cushion energy and food shocks. Confirmation would be rising cross-currency basis swaps, EM bond spread widening, and net outflows from carry-heavy funds; denial would require central bank signals or interventions that re-anchor expectations for low-for-long yields in Japan and the US.

## Drivers

- Warning of foreign Treasury demand dropping to 1990s-era lows
- Japanese government bond yields hitting four-decade highs
- Japan’s capex weakness raising questions about sustainable financing of deficits
- PBOC’s firmer yuan fix, affecting global FX dynamics
