Brent Futures Flat Price

In the news, President Zelenskyy confirmed a drone strike on Russia’s Perm oil refinery (226kb/d) overnight. Saudi crude exports via the northern Red Sea have risen by about a third since the July 20 Houthi blockade, reaching around 1.1mb/d, as Sinokor, Dynacom and DHT tankers shuttle 16.3mb from Yanbu to Ain Sukhna to bypass Bab el-Mandeb risk. Iranian crude availability for Chinese refiners is tightening sharply as the US blockade leaves around 40mb near Singapore with only 10% unsold, while Iranian Light has flipped from a $3.50/bbl discount to a $3.50/bbl premium to ICE Brent, signalling a potential supply squeeze from late September. China’s crude buying is expected to recover by up to 1.2mb/d into Q4, but high prices above $90/bbl and disrupted Middle East supplies are keeping imports below 2025 levels, with even bullish forecasts at just 9.9mb/d versus 12–13mb/d last year. The US EPA will allow winter-grade gasoline sales from Sep 1, two weeks earlier than usual, potentially adding hundreds of thousands of b/d of supply as gasoline prices remain above $4/gal amid the Iran war and supply concerns. Finally, the Oct/Nov’26 and Oct/Apr’27 Brent futures spreads are at $1.68/bbl and $11.00/bbl respectively.

Morning Macro

The 30-year bond yield is now back to 5.25% It's erased most of Treasury Secretary Bessent's intervention on Wednesday. This is not good for the bond market and the Bessent has clearly made a line in the sand. Markets don’t like it, precious metals continued to rally, gold up another 1% today, dollar continues to fall, S&P falls -0.8%, Nasdaq falls -0.7% and crypto continues to surge.

30y France close to wides against Bunds. We may worry about US treasuries but how can low growth, massive deficit France cope with yields here within the restrictions of the eurozone?
Walmart stock falls over -8% after posting a rare quarterly sales miss, with US growth falling to a 6-year low.? Walmart is one of the most efficient, well-managed businesses in the US. If it's suffering, just think how its lesser competitors are doing and how it will squeeze its suppliers given its vast buying power? It has been winning market share, gaining higher income customers. In real terms sales (ex auto fuel) are negative. But a sizeable number of the FOMC think that the economy is fine.

This looks like a textbook case of Jevons Paradox. Token prices have dropped, but compute costs have stayed elevated, which suggests cheaper tokens aren't reducing overall spend. Instead, they're driving so much more usage that total demand for inference, and the compute needed to serve it, keeps climbing.
