gold stays calm

On Monday, August 17, the memorandum between the United States and Iran expired after exactly 60 days, with no follow up agreement on the table. That same day, President Donald Trump told Fox News he would bomb Oman if the country got in the way of reopening the Strait of Hormuz. Oil prices immediately jumped to their highest level in weeks, with Brent climbing to $90.87 a barrel. Gold reacted too, but remarkably mildly, with spot gold rising less than one percent to around $4,417, well under the 2 percent daily threshold usually needed for a genuine price jump. Silver did better, climbing roughly 2 percent to above $66.

A truce that expired without a follow up

The memorandum signed by Washington and Tehran in early June gave both countries 60 days to reach a broader peace deal. That window has now expired without result. Trump told reporters at the White House he has no plans to extend it.

A few hours later, Trump went a step further in a phone interview with Fox News. Asked about the dragging talks between Oman and Iran over passage through the Strait of Hormuz, he said the United States would bomb Oman heavily if it got in the way. The White House offered no further clarification afterward. Oman has mediated the conflict between Washington and Tehran since it began, and had never before been threatened directly by the American president.

The US blockade keeps getting tighter

While diplomacy stalls, the US Navy has kept a blockade around Iran in place since July 14. This week a vessel was disabled for the third time. A US Navy helicopter fired two missiles into the engine room of the cargo ship Vela Nova, sailing under a Panamanian flag, which military command CENTCOM said was trying to reach an Iranian port despite repeated warnings.


55 vessels redirected by the US Navy since the blockade began on July 14, with a further 3 disabled and 2 boarded, according to CENTCOM.

Violence is also rising away from the blockade itself. This week two tankers flying the flag of the United Arab Emirates were attacked while trying to cross the Strait of Hormuz. Shipping traffic through the strait, normally responsible for roughly a fifth of the world’s oil transport, has now almost ground to a halt.

Tension is also rising on a second front

Away from the Strait of Hormuz, violence also flared between Israel and Lebanon. The Israeli military carried out its heaviest strikes on southern Lebanon last weekend since the late June truce, killing 11 people and wounding 19, according to Lebanon’s health ministry. Hezbollah threatened retaliation. Lebanese Prime Minister Nawaf Salam called the strikes a matter of the utmost gravity.

Why the gold price isn’t surging sharply

An escalating war suggests the gold price should automatically jump. This year that pattern has held less consistently. The oil price, rising on unrest around the Strait of Hormuz, also feeds fears of higher inflation, and that in turn pushes interest rates higher. Higher rates make savings products more attractive than gold, which pays no interest of its own. This week the flight to safety just barely wins out over that rate fear, partly because the US dollar fell to its lowest level in more than two months following a run of weak American data. Gold is climbing, but without the sharp jump you might expect from such a pile up of war headlines.

What this means if you want to sell old gold

For anyone looking to sell old gold, jewellery or coins, the core message stays the same as during earlier escalations this year. War headlines and threats do not automatically translate into a higher price, and waiting for the perfect moment is not a strategy. In early August, an apparent breakthrough around the Strait of Hormuz drove a price jump above $4,200, and that same arrangement is now stalled again. Anyone looking to sell old gold today would do well to check the current gold price at the moment of the actual appraisal, rather than betting on the next headline.

Check the price at the moment itself

The gold price can move sharply within a single day based on geopolitical news. The weight and purity of your jewellery or coins do not change because of that, only the price you are offered for them today. A free, no obligation appraisal shows exactly what your pieces are worth right now.

The same lesson applies for anyone looking to sell silver, whether cutlery, jewellery or coins. Silver climbed more sharply than gold this week, moving above $66, a move driven mainly by the weaker dollar rather than the war threat itself.

In short

The memorandum between the US and Iran expired Monday without a follow up deal, Trump threatened the same day to bomb Oman, and the US Navy disabled a vessel trying to breach the blockade against Iran for the third time. Despite that pile up of escalations, the gold price reaction stayed under one percent, while silver performed somewhat better. For anyone looking to sell gold or silver, the lesson remains the same as in recent months, today’s price says little about tomorrow’s.

Frequently asked questions

In early June, Washington and Tehran signed a memorandum of understanding, a temporary arrangement that gave both countries 60 days to reach a broader peace deal covering Iran's nuclear program and passage through the Strait of Hormuz. That window expired on August 17 without a follow up agreement, and President Trump immediately said he had no intention of extending it. That removes the temporary calm the memorandum had provided in recent weeks.

Since July 14, the US Navy has maintained a blockade around Iran to prevent vessels from carrying oil to or from Iranian ports. Ships that try to breach the blockade are first redirected. If they ignore warnings, the Navy can disable the vessel by targeting its steering gear or engine room. According to military command CENTCOM, 55 vessels have been redirected so far, 3 disabled and 2 boarded.

Gold has traditionally served as a safe haven in times of conflict, and that flight to safety normally pushes the price up. But a war that drives up the oil price also feeds fears of higher inflation. With more inflation, a central bank tends to keep interest rates higher for longer, and higher rates make savings products more attractive than gold, which pays no interest of its own. The two forces then work against each other, and this year the rate fear has repeatedly won out over the flight to safety.

The spot price is the price for gold delivered immediately today. The futures price is the price agreed now for delivery on a later, fixed date, for example in December. That futures price usually sits a bit higher than the spot price, partly because interest rates and storage costs are built into the price. News reports sometimes quote one, sometimes the other, which explains small differences between the levels mentioned.

Solid silver usually carries a hallmark, for example 800 or 925, showing the proportion of pure silver. Silver plated cutlery is a different base metal with a thin layer of silver on top, so it holds almost no material value. A hallmark is not always present or legible, and a simple test at a buyer quickly shows whether your pieces are solid.
