Frequently Asked Questions (FAQSchema Verified)
Why do Japanese life insurers use 3-month rolling FX forwards to hedge 10-year U.S. Treasuries?▼
Liquidity in 3-month FX forwards and FX swaps is substantially deeper than 10-year cross-currency swaps, though it exposes asset managers to short-term rate differential roll risk between SOFR and TONA.
What drives a negative EUR/USD or JPY/USD cross-currency basis?▼
A negative dollar basis indicates non-U.S. banks and institutional investors are paying a structural premium above covered interest parity (CIP) to borrow synthetic U.S. dollars via FX swaps.
