Dollar-Yen Breaks Above 159.50 as Fed Rate Hike Expectations Intensify

The dollar-yen pair has been advancing in European and US trading sessions due to speculation that the Federal Reserve will maintain its tightening monetary policy stance. The July Consumer Price Index (CPI) came in exactly as expected, with a year-over-year increase slowing modestly but month-over-month pace accelerating. This has tempered expectations for a September Fed rate hike, but the dollar's decline proved short-lived.

Elevated crude oil prices amid instability in the Middle East are also providing underlying support for the dollar. With Iran threatening to blockade the Strait of Hormuz and US-Iran peace negotiations struggling, the environment remains conducive to higher energy prices being perceived as inflationary pressure.

Takuya Kanda, senior analyst at Gaitame.com Research Institute, noted that the dollar-yen has achieved a 50% retracement of the decline triggered by the intervention episode between July 30 and August 3. He indicated that the next retracement target would be the 61.8% level, corresponding to the mid-160 yen range.

The US Producer Price Index (PPI) will be released tonight at 9:30 PM Japan time, with a market consensus calling for a 4.2% year-over-year increase. If inflation stickiness is confirmed, the upward trend in US long-term yields would strengthen, setting the stage for dollar buying to take the lead.

Gaitame.com Research Institute projects a dollar-yen range of 158.60 to 160.20. Whether the pair can break above the 160 level will be the immediate focus, but with intervention concerns running high, a clear break above 160 would likely require substantial catalysts.
