30 Second Briefing
Gold slid to within $20 of the $4,000/oz mark on Tuesday, with Comex August futures at $4,021.20/oz and spot at $4,015.17/oz, as traders weighed a Federal Reserve decision with a roughly one‑in‑three chance of a 25 bp hike and a fading Iran war premium. Silver fell 2.7% on Comex to $57.14/oz, close to its 2026 low of $55.50, while gold‑focused equities extended heavy year‑to‑date losses, with Equinox Gold down 35%, Gold Fields and Alamos each 26%. Newmont, banking on a 5‑million‑ounce lift from Lihir, is still 8% lower in 2026, as the top 50 miners collectively erased $228 billion in Q2 market value.
Technical Brief
- Comex August gold futures traded intraday down to $4,011.10/oz before partial recovery.
- Interest-rate swaps assign roughly a one‑in‑three probability to a 25 bp Fed hike.
- West Texas Intermediate slid below $78/bbl, more than 7% down over the past week.
- Bullion-backed ETFs recorded five consecutive days of net inflows, the longest streak since May.
- Bullion has fallen nearly 25% since the US–Iran conflict began five months ago.
- Newmont, Agnico, Barrick, Wheaton and Kinross dropped 1.7–2.6% in New York trading on Tuesday.
- Silver‑levered equities Hecla, Buenaventura, Equinox and Coeur declined 3.7–4.7% on the day.
- CME’s new 24/7 one‑ounce gold futures saw nearly 15,000 contracts, about $60 million notional, traded opening weekend.
Our Take
The pressure on gold and silver prices here echoes the 3% intraday drop to about $5,015/oz in the 9 March 2026 piece in our database, underscoring that rate expectations and dollar strength have repeatedly overridden safe-haven flows for bullion in 2026.
Newmont’s reliance on a 5-million-ounce uplift from Lihir, highlighted both in this article and the 24 July 2026 project update, means prolonged weakness in the gold price could push the company to prioritise high-margin ounces from Lihir over marginal assets elsewhere in its portfolio.
