Gold experienced a decline, trading near $4,020 an ounce, after previously falling almost 2%. This volatility comes as financial markets process conflicting signals regarding US-Iran relations, with negotiations set to begin in Doha. Washington confirmed the talks, while Iran's foreign ministry stated it would send experts but ruled out direct discussions. These geopolitical uncertainties are contributing to concerns about global inflationary pressures.

In the broader context, gold has seen significant downward pressure since the conflict began in late February, with a loss of approximately 25% and breaching key technical support levels, including the 200-day moving average. Despite some retreat in oil prices, the expectation of central banks maintaining higher interest rates for longer, coupled with a stronger US dollar, creates headwinds for non-yielding assets like gold. A stronger dollar makes gold more expensive for international buyers.

Adding to the market's unease, the US and Iran recently engaged in tit-for-tat attacks in the Persian Gulf, disrupting a ceasefire and causing energy prices to climb after a temporary dip. An attack on a tanker carrying Qatari crude further complicated shipping through the Strait of Hormuz. Analysts suggest that while easing geopolitical tensions could reduce inflation risks, the market is more focused on renewed US rate-hike expectations and a strengthening US dollar in the second half of the year, both of which increase the opportunity cost of holding gold. The latest US inflation data, although high, remained within analyst estimates.

The Federal Reserve's monetary policy outlook is a significant factor, with traders closely monitoring for potential interest rate hikes. The CME FedWatch tool indicates a nearly 48% probability of a rate hike as early as September. Elevated energy prices stemming from geopolitical risks are fueling inflation concerns, reinforcing expectations that interest rates will stay higher for an extended period, which diminishes the attractiveness of non-interest-bearing assets like gold. Technically, the selling pressure on gold has intensified since it broke below key support levels, transforming what began as profit-taking into a more substantial short-term momentum unwinding. Spot gold was down 1.3% at $3,962.80 an ounce in Singapore. Silver fell 1.7% to $57.28, and both platinum and palladium also declined. The Bloomberg US Dollar Spot Index gained 0.2% after three consecutive days of losses.

The US Supreme Court's ruling reinforcing the Federal Reserve's autonomy, allowing Governor Lisa Cook to remain in her position amidst efforts to oust her, also plays into market dynamics. This ruling underscores the independence of the US central bank at a time when it faces pressure to lower rates, despite some officials advocating for rate hikes to control inflation. Furthermore, Iranian Deputy Foreign Minister Kazem Gharibabadi stated Iran's intention to continue overseeing traffic through the Strait of Hormuz, a move opposed by the US, Europe, and Gulf Arab nations, highlighting ongoing disputes over the waterway's management.
