The yen strengthened against the dollar and euro in holiday-thinned trading after Bank of Japan board members signaled growing confidence in achieving sustainable inflation, prompting traders to accelerate bets on policy normalization in early 2026.
Market participants say December's Tokyo inflation data, which exceeded the central bank's target for a fourth consecutive month, has emboldened policymakers to consider a faster exit from negative interest rates. The timing of these hints, just ahead of the year-end period when liquidity typically evaporates, has amplified currency moves as carry trades face renewed scrutiny.
Key factors driving the move include:
- BoJ communication: Senior officials have emphasized wage growth has become "broad-based," a phrase traders interpret as laying groundwork for policy adjustment
- Positioning dynamics: Leveraged funds have reduced short-yen positions by the most since March, according to traders familiar with CFTC data, suggesting the market is positioned for further strength
- Safe-haven flows: Renewed tensions in the Middle East and uncertainty around U.S. trade policy heading into the presidential inauguration next month have driven investors toward traditional safe-haven assets
USD/JPY has trended lower throughout the week, with momentum indicators suggesting the pair may test key technical support levels that have held since October. Cross-yen pairs are similarly under pressure, as investors unwind positions funded by the historically low-yielding currency. The unwinding has rippled through equity markets, with the Nikkei 225 sliding in tandem as export-heavy stocks face headwinds from a stronger domestic currency.
Gold prices have advanced alongside the yen's strength, reflecting heightened demand for safe-haven assets. Oil markets remain subdued after volatile trading earlier in December, though concerns about demand growth continue to weigh on energy markets. Bitcoin's correlation with traditional risk assets has weakened notably this month, with traders observing that the cryptocurrency is increasingly trading on its own fundamental drivers rather than simply following equity flows.
Looking ahead, market focus turns to the BoJ's January policy meeting, where economists expect officials to provide clearer guidance on the timing of rate increases. U.S. inflation data due in early January will also be critical for determining whether the divergence between Fed and BoJ policy paths continues to narrow. Technical analysts note that a sustained break below current support levels could accelerate the move, particularly if year-end positioning extends into the new year.
