Brent Futures Flat Price

Oct'26 Brent crude futures reached daily resistance at $92.80/bbl at around 03:30 BST and dropped to $89.30/bbl at 11:20 BST (time of writing). US launches “Operation Economic Outcast”: Treasury sanctioned 60 individuals, companies and vessels linked to Iran’s oil smuggling, military procurement, missile/nuclear programmes and cyber activity. But the bigger change is the expansion of secondary-sanctions pressure: Washington is warning foreign governments, banks and companies that continuing business with Iran could ultimately cost them access to the US financial system. Bessent described the objective as “economic asphyxiation” and said no country is beyond the reach of US sanctions. Ukraine hit multiple Russian targets overnight; Kyiv reportedly struck the 125kb/d Afipsky refinery, where a fire was reported, alongside a MiG-29, two Black Sea vessels and a rocket-fuel plant in Rostov. Putin signed a decree allowing the state to temporarily take control of critical private infrastructure if owners fail to adequately protect or restore it after attacks. The measure covers fuel, energy, industrial, transport, communications and logistics assets, with the Kremlin insisting it is not formal nationalisation. An oil tanker was struck and disabled by an unknown projectile in the Strait of Hormuz, around 9 nautical miles northeast of Ash Shishah, Oman, with the impact damaging the engine room; all crew were safe. Finally, the Oct/Nov’26 and Oct/Apr’27 Brent futures spreads are at $1.38/bbl and $9.04/bbl, respectively.

Morning Macro

Druckenmiller on Bessent's ‘actions’:
"I have spent five decades trading on a simple premise: Markets aggregate information no committee possesses, and prices are how that information reaches decision makers. The long-term Treasury yield is the most important price in the world. It is also the only fiscal disciplinarian the U.S. has left."

"If the 30-year must trade at 5.5% to clear, that isn’t a crisis. It is an invoice. Then do the only thing that durably lowers long-term yields: address the primary deficit."

Gold rallies another 1%. Chinese gold demand is surging back, with open interest in Shanghai Futures Exchange gold futures spiking to nearly 400,000 lots - one of the largest two-day increases in five years - suggesting aggressive new long positioning rather than simply rolling existing contracts. (Goldman Sachs)

Shares of Newmont, the world’s largest gold producer, are up 45% in just four weeks - one of the biggest rallies in the company’s history.

The Bloomberg Commodity Index has SURGED by a STAGGERING 38% over the past year.

Trump has escalated the U.S.-Canada trade war by threatening to double auto tariffs to 50% and impose new parts tariffs from January, following a breakdown in negotiations that already triggered a 50% levy on Canadian furniture, plastics and electrical equipment - with Canada vowing retaliation, the Canadian dollar sliding, and economists estimating up to 90,000 Canadian jobs at risk if the measures persist.
