USD/JPY hovers around 159.00 on Wednesday. The pair is near its highest level in almost seven weeks as the Japanese Yen (JPY) remains weak against the US Dollar (USD). Driving the pair’s strength is US Dollar outperformance, fuelled by concerns that the Federal Reserve (Fed) could opt for a larger interest rate increase at its December meeting.

At the time of writing, a 0.1% gain puts the US Dollar Index (DXY) near 102.32. The index measures the Greenback against six major currencies.
With United States (US) inflationary pressures accelerating in October, financial markets have begun pricing in a 50 basis points (bps) interest rate increase by the Fed at its December meeting.
US inflation overshoot complicates Fed policy outlook
A fresh setback for the disinflation narrative is evident in the latest data, according to economists at Rabobank. They note that “yesterday’s US CPI print came in hotter than expected at 0.4% m-o-m headline vs. a consensus of 0.3% and 0.3% core vs. a 0.2% market view,” highlighting the renewed challenge.
To underline that concern, Rabobank cites the “usually dovish Fed voter Goolsbee, ‘it’s another distressing report, borderline disturbing. We’ve been hoping to get progress.’” Rather than a further easing of price pressures, the bank identifies “an acceleration in grocery and food inflation, persistent housing/shelter price pressure, and a delayed pass-through from earlier energy shocks feeding into medical care, household furnishings, and other daily expenses,” reinforcing worries that underlying inflation remains firmly entrenched.
Japan’s October Producer Price Index (PPI), due on Thursday, is the focus in Tokyo. Producer prices are estimated to have risen 0.3% month-on-month (MoM), reversing a decline of the same size in September.

At 158.88 on the daily chart, USD/JPY sits near the top of a consolidation range that has lasted almost seven weeks. A position above the 20-day Exponential Moving Average (EMA), currently at 158.10, keeps the near-term outlook bullish. As the pair pulls further away from this dynamic support, the Relative Strength Index (RSI) is rising in positive territory at 57.38. This suggests buyers remain in control, without signs that the market is yet overstretched.
The 20-day EMA at 158.10 provides the first downside support. A daily close below it would signal fading upward pressure and the prospect of a deeper correction towards the range’s lower boundary near 156.00. Conversely, a decisive break above 159.00 would open a new upward leg, with 160.00 and September’s high of 160.39 marking key resistance.

Responsibility for US monetary policy rests with the Federal Reserve (Fed). Price stability and full employment form its dual mandate, with interest rate adjustments serving as the main means of pursuing those objectives. If prices climb too rapidly and inflation exceeds the Fed’s 2% target, the central bank increases rates. Higher borrowing costs across the economy make the US more attractive to international investors seeking to place funds, strengthening the US Dollar (USD). By contrast, inflation below 2% or an excessively high unemployment rate may prompt the Fed to cut rates to stimulate borrowing. This puts pressure on the Greenback.
Eight times a year, the Federal Reserve (Fed) convenes policy meetings at which the Federal Open Market Committee (FOMC) reviews economic conditions and determines monetary policy. Twelve Fed officials attend the FOMC: all seven Board of Governors members, the president of the Federal Reserve Bank of New York and four presidents drawn from the other eleven regional Reserve Banks. These four serve rotating one-year terms.
When conditions become extreme, Quantitative Easing (QE) is one policy the Federal Reserve may adopt. It substantially expands the flow of credit through a financial system that has stalled. As an unconventional policy tool, QE is deployed during crises or periods of exceptionally low inflation. During the Great Financial Crisis in 2008, it was the Fed’s preferred response. The process involves creating more Dollars and purchasing high-grade bonds from financial institutions with them. The US Dollar typically weakens under QE.
By reversing QE, quantitative tightening (QT) typically supports the US Dollar’s value. Under QT, the Federal Reserve ceases bond purchases from financial institutions. It also allows its existing bonds to mature without reinvesting the principal in new bonds.
