Yen Firms Ahead of Fed Meeting

The broader backdrop points to a market still wary of policy surprises. U.S. 10-year Treasury yields were trading around 4.96%, down from 5.0% late last week, while two-year yields held near 4.65%, suggesting investors are trimming some bets on further U.S. tightening. The federal funds rate forecast for October stands at 3.726%, versus 3.75% in September, underscoring expectations that the Fed will keep policy restrictive but not necessarily accelerate it. The dollar index was near 102.39, below its recent intraday highs, though still above its 50-day moving average and with the 200-day average acting as support.

In Japan, the yen’s recovery remains fragile. Invesco’s CurrencyShares Japanese Yen Trust, a proxy for the currency, was little changed around 58.1 after recovering from earlier weakness, reflecting how quickly FX sentiment has swung. Technically, the dollar-yen move has been volatile rather than decisive, and traders appear reluctant to press aggressive bets until the Fed clarifies whether U.S. rates will stay higher for longer.

The stakes extend beyond the currency pair itself. A firmer yen would ease imported inflation for Japanese consumers and companies, but it could also weigh on exporters and on the Nikkei’s large earnings base, especially if the move is driven by a broad dollar selloff rather than Japan-specific strength. Conversely, a renewed dollar rebound would likely revive pressure on the yen and keep imported costs elevated in Japan, reinforcing the view that the Bank of Japan still has limited room to normalize policy quickly.

For investors, the immediate question is whether the Fed meeting confirms a plateau in U.S. yields or reopens the case for higher-for-longer pricing. A cooler dollar and lower Treasury yields would favor yen bulls and challenge the recent consensus that the currency can only weaken from here. But if the Fed sounds firmer than markets expect, the dollar’s yield advantage could reassert itself fast.
