United States Dollar Index trades under pressure as Yen buying accelerates

The US Dollar Index (DXY) is trading lower on Monday as the Japanese Yen (JPY) experiences a significant rally, pushing the DXY down to around 98.90, a 0.26% decrease for the day and nearing two-week lows. The subdued trading conditions are due to the US stock and bond markets being closed for the Labor Day holiday. USD/JPY has fallen to a six-and-a-half-month low near 154.40, supported by hawkish Bank of Japan (BoJ) expectations, capital repatriation, and unwinding of Yen-funded carry trades.

Inflation concerns, policy credibility questions, and political risks further weigh on the Greenback, maintaining the conversation around US Dollar debasement. Attention will also shift to the US Treasury's planned buybacks of longer-dated government securities on Wednesday, which may impact bond yields and sentiment towards the currency.

Fed Chairman Jerome Powell's Jackson Hole speech has helped ease concerns about policy credibility and reduce the risk of weak policy dragging down the dollar. Traders have increased expectations of a rate hike at the Fed's September 15-16 meeting following a strong employment report. Meanwhile, rising oil prices due to Middle East supply concerns and heightened inflation risks further support the case for tighter monetary policy.

The US military reported striking three Iranian crude oil tankers on Saturday in response to Iran firing ballistic missiles at two US Navy ships. The Financial Times also mentioned a fresh strike on Saudi Aramco's Jazan refinery on Monday. According to the CME FedWatch Tool, there is a 58% chance that the US central bank will raise interest rates next week.

Inflation data, including the Producer Price Index (PP) on Thursday and the Consumer Price Index (CPI) on Friday, will be crucial in testing rate expectations ahead of the decision. The Federal Reserve's mandates include achieving price stability and full employment through interest rate adjustments. When inflation is above the 2% target, the Fed raises interest rates, strengthening the US Dollar.

Conversely, when inflation falls below the target or unemployment is too high, the Fed may lower rates to encourage borrowing and weaken the Dollar. The Fed holds eight policy meetings annually to assess conditions and make monetary policy decisions. In exceptional circumstances, the Fed may employ Quantitative Easing (QE), a non-standard policy measure used during crises or when inflation is extremely low.

QE involves the Fed printing more Dollars and purchasing high-grade bonds from financial institutions, weakening the US Dollar. Quantitative tightening (QT) is the opposite process, where the Fed stops buying bonds and does not reinvest the principal from maturing bonds, typically strengthening the US Dollar.
