QUESTIONS ANSWERED

US Dollar / Japanese Yen FAQ

Why does USD/JPY follow US yields?

Higher relative US yields can increase the attraction of holding dollars versus low-yielding yen, though the relationship is not permanent.

What is intervention risk?

Japanese authorities may enter the currency market or signal concern about disorderly moves, creating abrupt volatility.

Is the yen always a safe haven?

No. Safe-haven behaviour depends on funding positions, policy conditions and the nature of the risk event.

Which session matters most?

Tokyo is important for local flows, while London and New York can dominate when US yields or global risk are moving.
