Gold is experiencing a significant downturn, with spot gold falling by 1.5% to 3% to trade between $4,156 and $4,223.95 per ounce, marking its lowest level since August 5. US gold futures also saw a 1.5% decrease, dropping to $4,257.90. This decline is largely attributed to mounting expectations of further interest rate hikes by the Federal Reserve, escalating oil prices, and a strengthening US dollar, which collectively increase the opportunity cost of holding non-yielding gold.

The market is now pricing in a 66% to 70% chance of another Fed rate hike in October, following a 25-basis-point increase earlier in September. This hawkish outlook is reinforced by recent comments from Fed officials, including Cleveland Fed President Beth Hammack, Fed Governor Michael Barr, and Boston Fed President Susan Collins, who have all indicated that additional tightening may be necessary to control persistent inflation. Rising oil prices, with Brent crude climbing to $107.16 per barrel, are fueling inflation concerns and pushing global bond yields, such as the 10-year US Treasury yield, to multi-year highs of 5.23%.

The dollar index has reached a two-month high of 101.16-101.39, making gold more expensive for holders of other currencies. Analysts like Tim Waterer of KCM Trade note that the combination of high bond yields and oil prices acts as a significant drag on gold. The upcoming week's US economic data, including Personal Consumption Expenditures (PCE) inflation, ISM Purchasing Managers' Index (PMI), and Nonfarm Payrolls (NFP), will be closely watched for further clues on the Fed's monetary policy direction. Strong economic data, especially regarding inflation and employment, could solidify expectations for an October rate hike, further pressuring gold prices.
