Deutsche Bank analysis shows global growth stability has made yield spreads the primary driver of currency markets this year.
Currency markets in 2026 have been overwhelmingly driven by yield differentials, sidelining other factors like geopolitical tensions or Fed leadership changes. Deutsche Bank’s analysis highlights that resilient global growth has kept volatility low, allowing carry trades to prevail as the dominant strategy.
The yen exemplifies the trend, with front-end yields too low compared to global peers, creating a structural disadvantage. Deutsche Bank identifies two potential resolutions: faster-than-expected BoJ tightening to 2% or policy measures to repatriate domestic capital, such as tax changes or GPIF adjustments. The bank advises funding carry trades with CHF rather than JPY due to these risks.
Historical precedent from 2014 suggests shifts in capital flow expectations can move currencies well before policy implementation. With growth resilience expected to persist, yield differentials are likely to remain the key driver in coming months.
