Brent Futures Flat Price

Nov’26 Brent futures rallied to a high of $99.46/bbl at 09:30 BST and is softer at $98.35/bbl at 10:42 BST (time of writing). Iran raised the threat level around Hormuz, saying it plans to establish a maritime “exclusion zone” outside the Strait and that vessels entering without Iranian permission could be targeted. Tehran also said its upgraded Qassem Basir ballistic missile had been used against US warships and warned that US naval forces enforcing the blockade are now legitimate targets. The Houthi campaign against Saudi Arabia escalated sharply, with ballistic missiles and drones targeting Abha, Khamis Mushait, Jazan and Najran. Houthi media said targets included Abha airport, King Khalid air base and Aramco facilities in Abha and Jizan. Jizan’s oil infrastructure was hit, with fires reported at the Jizan refinery. The attacks came alongside renewed Houthi ground fighting against Saudi-backed Yemeni forces, while Riyadh said it would take “all necessary operational measures” in response. Trans Mountain is accelerating efforts to expand west-coast exports to Asia as the Iran war disrupts Persian Gulf flows and Canada seeks to diversify trade away from the US. West-coast capacity will rise from 890 kb/d to ~980 kb/d by end-2026, with a further increase to 1.2 mb/d by end-2028, followed by another 1 mb/d between 2032–34. CEO Mark Maki said the additional capacity is being brought forward by geopolitics, with heavy Canadian crude expected to target strong demand in China, India, South Korea and Thailand, particularly as Asian buyers reassess supply security. Russia resumed missile and drone strikes on Kyiv after the three-day pause during US envoy visits. Ukraine said it intercepted a range of weapons, including ballistic missiles and drones. Nov/Dec’26 and Nov/May’27 Brent futures spreads are at $4.04/bbl and $15.98/bbl, respectively.

Morning Macro

LME copper just notched a new all-time high. Worth flagging: ore grades are declining even as demand grows, and current projections point to a copper shortfall of roughly 100 million tonnes per year between 2030 and 2040.

USD/JPY is breaking down decisively. Putting pressure on the carry trade (yen financing of global asset purchases).

The 10 year rolling returns on Treasuries is now -2%, the worst in 100 YEARS.

While the S&P 500 looks calm on the surface, single-stock and cross-sector volatility have surged to levels last seen since the 2020 crash - a divergence that's historically preceded broader market stress, most notably the 2000 Dot-Com Bubble. The longer this gap between surface calm and underlying turbulence persists, the greater the risk it spills into the broader market.

An unexpected bounce in Friday’s payrolls, Wall Street expected +55,000 jobs in August.

The US economy delivered +162,000. Unemployment rate remains 4.1%. This makes the Sep 16th Fed meeting critical. OIS now prices 60% chance they hike but expect volatility. The hike, equities suffer and Warsh is seen as more hawkish, but if they stay on hold he’s seen as Trump’s puppet and bonds fall hard (yields higher)

Correlation between the 10Y and oil is the highest since the GFC.

German & Dutch gas storage levels look dangerously low heading towards winter.

The Dutch central bank moved 86 tonnes of gold out of New York and Ottawa to London. More than 1/4 of everything they held in North America. Done quietly between March and August, announced today. New York went from 31.3% of their reserves to 18.5%. London went from 18.1% to 32.1%. Stated reason is “increasing geopolitical unrest” and crisis readiness.

Short interest in the median S&P 500 stock is up to 3.2% of market cap, the highest level since 2009. This is now approaching the 2008 Financial Crisis peak of ~3.8%. By comparison, during the 2022 bear market, this percentage was ~1.7%. Furthermore, short interest among the most heavily shorted 10% of S&P 500 stocks is up to 8.0% of market cap, the highest in 8 years. Even during the 2000 Dot-Com Bubble burst, short interest never surged to these levels. The short trade is starting to look overcrowded.

Snowflake stock, surges over +22% after reporting stronger than expected earnings due to AI demand.
