Gold prices have experienced a dramatic sell-off, driven by mounting concerns that the Federal Reserve could announce an unexpected interest rate hike this week. The precious metal's decline has continued into Wednesday's Asian trading session, following a sharp drop on Tuesday.

On Tuesday, spot gold plunged nearly $48, closing near $4,028 per ounce. By Wednesday morning in Asia, prices had slipped further to around $4,010 per ounce. The US dollar's strength, holding near a one-month high, has made gold—which is priced in dollars—more expensive for international buyers, adding to the downward pressure.

Why the market is jittery

Interest rate swap markets are now pricing in roughly a one-in-three chance that the Fed will raise rates by 25 basis points. Such high uncertainty so close to a rate decision is rare by recent market standards. Because gold offers no interest yield, rising borrowing costs tend to weigh heavily on its appeal.

Fed policymakers appear to be caught in a dilemma. On one hand, inflation data released in June came in lower than expected. On the other hand, renewed conflict between the US and Iran in July has pushed oil prices higher, intensifying concerns about inflation.

David Meger, head of metals trading at High Ridge Futures, noted: "Energy prices staying elevated is a key inflation risk for Fed officials. Market expectations are leaning toward a hawkish stance, which is boosting rate hike bets and the dollar, putting further pressure on gold."

Key data and outlook

Adding to the uncertainty, the US Personal Consumption Expenditures (PCE) price index for June—a key inflation gauge watched closely by the Fed—is set to be released on Thursday. This report could provide further clues on the direction of monetary policy.

Commerzbank has slashed its year-end gold price forecast by $300, to $4,500 per ounce. The bank warned that unless market expectations on interest rates reverse, it will be difficult for gold ETF inflows to sustain a recovery, making a significant rebound in gold prices unlikely.

Oil and geopolitical tensions

Crude oil prices rebounded on Wednesday after three consecutive days of losses, supported by ongoing tensions in the Middle East. Four days after the US ended a nearly two-week-long campaign of airstrikes against Iran, President Donald Trump met with Israeli Prime Minister Benjamin Netanyahu at the White House in an effort to pave the way for further diplomatic efforts.

Meanwhile, the US military reported that it had intercepted an "attempted surprise attack" targeting American forces stationed in the Middle East.

Gold's performance and key support

Since the outbreak of the US-Iran war on February 28, gold prices have lost nearly 25% of their value. Rising energy costs have amplified concerns about inflationary pressures. However, gold has managed to hold above the key support level of $4,000 per ounce since late June, buoyed by a wave of dip-buying from investors.
