Asia FX: yen intervention in focus as rate hike bets put dollar near 19-mth high

 Most Asian currencies moved in a flat-to-low range on Friday, with the Japanese yen back in sight of levels that had last attracted massive intervention measures from Tokyo. 

Regional currencies were pressured by persistent strength in the dollar, which sat close to a 19-month high amid growing conviction that the Federal Reserve will raise interest rates in December. 

Markets held back before a wave of key economic indicators from China and Japan due next week. The Chinese yuan’s USDCNY pair moved little on Friday but was in sight of recent four-year highs. 

Japanese yen nears 160, draws intervention warnings 

The Japanese yen’s USD/JPY pair rose 0.08% to 159.96 after briefly crossing 160 yen overnight.

The move drew warnings from Japanese officials against what they call “one-sided moves” in foreign exchange markets, which could herald more intervention measures from Tokyo.

The yen’s last tryst above 160– in early-September– had drawn billions of dollars in an unprecedented joint intervention by Tokyo and Washington. 

Top Japanese currency diplomat Atsushi Mimura on Thursday said it was “too early to forget” September’s intervention.

Weakness in the yen comes chiefly from growing bets that a gulf between Japanese and U.S. interest rates will persist in the coming months, even as the Bank of Japan prepares to further raise rates.

Japanese gross domestic product data for the third quarter is due next week, as is key consumer price index inflation data for October. Both prints are likely to factor into the BOJ’s plans for rates. 

Dollar near 19-mth peak, set for strong week as rate hike bets grow

The dollar index and dollar index futures steadied in Asian trade, but were close to their highest levels since early-2025 amid growing bets on a December interest rate hike by the Fed.

The greenback was set to add 0.8% this week, its third straight week of gains. 

Strong U.S. consumer inflation data for October ramped up bets that the Fed will hike rates in December, with markets skewed towards a 25 basis point raise. 

Some traders were also seen pricing in a small chance for a 50 bps hike, CME Fedwatch showed.

Producer price index inflation for October is due later on Friday, with any signs of sticky inflation likely to further the case for more rate hikes by the Fed. The central bank has largely maintained its annual inflation target of 2%, spurring bets that more rate hikes will be needed to meet the target.

Beyond the PPI data, several Fed policymakers are also set to speak on Friday. 

Higher U.S. rates herald more pressure on high-yielding, risk-heavy Asian currencies, given that they tend to narrow the gap between yields on the relatively safer dollar.

This weighed on most regional units, with the Australian dollar’s AUD/USD pair falling slightly on Friday and coming close to its weakest levels in 2026. 

The Singapore dollar’s USD/SGD pair was flat but was close to its highest level since end-July, while the South Korean won’s USD/KRW pair fell 0.3%. 

The Indian rupee’s USD/INR pair rose 0.1% but remained well below recent record highs, as a drop in oil prices aided the currency.
