Yen’s 40‑year low fuels bets on a trend reversal that could destabilise global carry trades
Executive summary: The yen has weakened to a 40‑year low versus the dollar, prompting investors to bet on a forthcoming trend reversal that could unsettle global carry‑trade strategies. Carry trades rely on interest‑rate gaps; a yen rebound would trigger a swift unwind of leveraged positions, increasing FX volatility and affecting assets funded by cheap yen.
Who is involved: Japanese yen, global investors executing carry trades, the European Central Bank (via Christine Lagarde’s comments), and the Bank of Japan.
Likely next: Markets will watch for BoJ policy signals and ECB commentary on rates; any shift could trigger rapid repositioning in carry‑trade positions.
The Japanese yen has slipped to its weakest level against the dollar in four decades, making yen‑funded carry trades highly profitable. Speculators are now positioning for a possible trend reversal, which would force rapid unwinding of those positions. Such a move could spike FX volatility and affect assets financed by cheap yen, while central‑bank signals—particularly from the ECB and BoJ—will determine whether the reversal materialises.
