Yen's Fortunes Turn as Carry Trade Unwinds and BOJ Raises Interest Rates

The yen has been experiencing a significant shift in its fortunes, moving away from its four-decade low against the dollar. A combination of factors is contributing to this change, including capital repatriation, unwinding carry trades, and U.S. political pressure.

Rong Ren Goh, a fixed income portfolio manager at Eastspring Investments, noted that 'investors seem increasingly reluctant to aggressively short the JPY.' The Bank of Japan is expected to raise its key rate by 25 basis points this month, with some market participants anticipating a 50-basis-point hike or rapid increases in the months ahead.

Citigroup data indicates that positioning on the yen has flipped from bearish to bullish since August. Leveraged funds, banks, and real-money investors are net buying yen, contributing to the currency's 2.3% surge against the greenback this week.
