Commodities Wrap 17 August: Brent Tops 90 as the Iran Deadline Runs Out
Energy led a broad commodities advance on Monday as the 60-day deadline under the June memorandum between the United States and Iran expired with Tehran ruling out an extension, per CNBC. ICE Brent for October was quoted at 90.98 dollars a barrel in late trading, up 2.78 percent after touching 91 dollars, with WTI for September up 2.73 percent at 84.65 dollars, while cocoa jumped 5.28 percent in the day’s largest single move, per CNBC. 14 of the 17 contracts tracked here were higher at the 18:35 GMT capture, our calculation.
Agriculture, energy and metals figures are late-session quotations captured at 18:35 GMT and should not be read as official settlement prices. Currencies, the volatility index and Bitcoin are intraday readings, while United States Treasury yields are Friday 14 August official closes, carried for reference.
In energy, the refined products ran ahead of crude. ULSD heating oil was the strongest contract in the complex, up 3.88 percent at 4.4492 dollars a gallon, with RBOB gasoline up 2.74 percent at 3.2714 dollars, per CNBC. Natural gas was the only decline in the complex, down 1.57 percent at 2.690 dollars per million British thermal units. The June 17 memorandum was supposed to open the Strait of Hormuz while the two sides negotiated a final deal within 60 days; that deadline expired on Monday with Iran saying negotiations never started, per CNBC, and shipping through the strait had already slowed to 3 vessels on Sunday against a 5-day average of 12, per Kpler data cited by CNBC.
In metals, the move was broad but not uniform. Platinum led, up 1.55 percent at 1,784.20 dollars an ounce, with silver up 1.47 percent at 66.065 dollars and COMEX gold for December up 0.64 percent at 4,465.70 dollars, above Friday’s settlement of 4,437.30, per CNBC. Palladium added 0.34 percent to 1,330.00 dollars, while copper was the only metal lower, easing 0.11 percent to 6.606 dollars a pound.
Agriculture produced the day’s single largest move. Cocoa jumped 5.28 percent to 6,078.00 dollars a tonne, recovering the ground lost in last Tuesday’s 4.97 percent break, counted from our published wraps. Soybeans rose 1.97 percent to 1,216.00 cents a bushel, sugar 1.81 percent to 16.90 cents a pound, corn 1.19 percent to 489.00 cents, coffee 1.07 percent to 317.65 cents and cotton 0.85 percent to 85.52 cents, per CNBC. Wheat was effectively flat, down 0.04 percent at 689.25 cents a bushel.
In rates and the wider market, the risk gauges moved more than the dollar. The Cboe Volatility Index rose 6.32 percent to 15.15 against Friday’s close, per Cboe, while the US dollar index was little changed at 99.638, down 0.03 percent, per CNBC. Bitcoin added 2.03 percent to 64,384.60 dollars, per CNBC. The euro was flat at 1.1572 and the yen weakened 0.18 percent to 159.58 per dollar, per CNBC. United States Treasury yields carry Friday’s official closes for reference, with the 10-year at 4.68 percent, and Monday’s official curve, derived from quotations at or near 7:30 PM GMT, publishes after the New York close.

Why it matters: Monday moved the Hormuz story from a negotiation with a deadline to one without a clock, and the board priced it that way, our reading, even with the separate Oman channel on transit arrangements still active, per CNBC. Four of the five tracked energy contracts rose with refined products leading, the volatility index climbed 6.32 percent while the dollar index was flat, and that combination reads as a supply risk premium being priced rather than a dollar effect, though the volatility gauge shows broader risk aversion was present as well. The breadth matters too: 14 of 17 contracts higher is a firm board, but the day’s largest move belonged to cocoa, not crude, a reminder that the softs are running their own violent repricing cycle in both directions, with Monday’s 5.28 percent jump recovering last Tuesday’s break of nearly the same size.
Outlook: The markers from here are whether Brent holds above 90 dollars once the weekly US inventory cycle lands, whether the strait’s transit count recovers from the weekend’s near-standstill or stays pinned, and how the official rates response reads when the United States Treasury publishes Monday’s curve after the New York close, our reading. Tuesday brings the first full trading day with no memorandum in place on either side.
