December Japanese Yen futures rebounded after three consecutive sessions of declines, though the currency has only retraced roughly 25% of the recent downward move. Yield differentials remain a key focus as the 10-Year JGB yield reached its highest level since 1998, suggesting investors are demanding more compensation for holding Japanese debt. Meanwhile, the U.S. dollar traded weaker against major currencies, including the Swiss franc and British pound, as markets awaited the upcoming FOMC decision to gauge the potential direction of interest rates.
