La combinaison d'une Fed dovish et d'uneBOJ hawkish crée un "effet ciseaux" amplifiant le risque fatal. Le mécanisme repose sur une forte divergence des taux d'intérêt anticipée entre décembre 2025 et début 2026 (Fed coupant de 25-50 pb, BOJ remontant de 25-50 pb).
Ceci comprime le spread de rendement de 3.25% à 2.25%-2.75%. L'impact…
The yen carry trade relies on exploiting the interest rate differential between Japan (low) and foreign countries (high), adjusted by the exchange rate variation ROI_Carry (r_foreign - r_domestic) - ΔS_fx + α(Leverage) - β(Costs).
Historically, this model has generated annualized returns of about 35-40% due to an average favorable spread of 4.40% and a leverage…
The Japanese yen-based carry trade, historically profitable (35-40% ROI with 10x leverage), is mathematically broken by the Bank of Japan's (BOJ) rate normalization.
The current rate differential (4.25% US vs 1.00% JPY) drops to 3.25% before costs and yen appreciation. If the BOJ raises rates by more than an additional 50 basis points or…
