Oil blows past $90 and the reserve is nearly empty
Brent jumped nearly 3% on fresh US-Iran strikes while the government's emergency oil stash sits at historic lows and rate-hike odds climb past 60%.
Monday, 31 August 2026
Brent crude hit $90.70 a barrel on Monday. The US and Iran acknowledged hitting each other for the first time in over a month.
And the Strategic Petroleum Reserve, the government's emergency stash of crude stored in underground salt caverns, is at historic lows. So the tool Washington uses to cool a price spike has almost nothing left.
The S&P 500 fell 0.35% to 7,685.01. The Dow dropped 0.70% to 53,186. Not dramatic on the surface. But if you're paying a mortgage or filling up a car, the crosscurrents underneath matter more than the index.

Bonds tighten on both sides
The 10-year Treasury yield, the interest rate the US government pays to borrow for a decade, rose to 4.76%. Up from 4.72% on Friday. And Germany's 10-year yield hit its highest since 2011.
So what does a German bond have to do with you? When yields rise everywhere at once, every borrower pays more. Your mortgage. Your car loan. Your company's line of credit.
New home sales dropped to a 7-month low. Jim Tobin, head of the National Association of Home Builders, called the market "historically rough." But notice which story builders want you to hear. If rates are the villain, a future cut fixes everything. Overbuilding doesn't fix itself.
Oil and the empty cushion
Persian Gulf oil flows are still about 60% below prewar levels. 6 months into this conflict.
Treasury Secretary Bessent said the US "will get on the other side" of it, and announced sanctions on another bank. But he unveiled a broader sanctions package just a week ago, and that one didn't stop the fighting either. So you have to ask who benefits from the idea that sanctions alone can bring oil down. The administration does, because it needs cheaper energy before any rate hike lands on your monthly payments.
Reports over the weekend said Trump struck a deal for a fifth of Venezuela's oil reserves. But Venezuelan crude is heavy. It takes time to reach your petrol pump. And promises of new supply have come before.
Warsh keeps saying it
Fed Chair Kevin Warsh has said some version of the same thing 4 times in 5 days. Inflation is not beaten. He said it at Jackson Hole on Friday and again at the G20 in Asheville on Monday.
Rate-hike odds jumped from 36% to above 60%. Is he bluffing? No vote yet. The September meeting is 2 weeks away.
But the PCE price index, the Fed's preferred measure of inflation, sits at 3.3%. And oil climbing again makes everything more expensive to ship, which gives Warsh less room to back down. If that 60% number climbs past 75%, you can stop calling it a hint.
China crosses a chip line
Chinese chipmaker CXMT has started producing high-bandwidth memory in small batches, fast chips stacked in layers, the kind that power AI training. US export controls were designed to stop exactly this.
Small batches is not mass production. But can CXMT scale? You don't know the yield yet, the share of chips that actually work. And a Chinese court froze Dutch chipmaker Nexperia's stakes in 4 Chinese units. So the chip fight runs both ways now.
Pharma deals and AI warnings
Trump is expected to announce new drug-pricing deals with pharma companies. 9 major pharma stocks hit 52-week highs in August, so drug companies have every reason to hand the president a friendly headline while shares sit near peaks. If you take prescription medicine, the number to watch is net prices in the quarterly filings 2 quarters from now, not the announcement.
At the G20, the Financial Stability Board warned that AI-powered trading moves faster than any human can react. But no global regulator has authority over cross-border AI trading. Who gets it?
Metals at spot
Gold spot sits at $4,451.13, down from Friday's close of $4,458.48. It dropped 3% on Friday after Warsh's rate-hike signal, because higher rates make gold, which pays you nothing to hold, less attractive.
Still above $4,400 though. People are paying up for protection even with a hike on the table.
Silver spot is $66.44. Copper is $6.70 a pound.
Two earnings, two misses
LexinFintech reported Q3 revenue of $469 million against a $472 million estimate. Looks small. But net income has fallen 80% in 4 quarters, from $521 million down to $101 million. And free cash flow margin, the share of revenue that turns into cash the company actually keeps, has been 0.0% for 4 straight quarters.
BW LPG, a shipping company that moves liquefied gas, missed badly. Revenue came in at $275 million against $318 million expected. Earnings per share hit $0.79 versus a $1.17 target. Its trading arm made money, but bonus pay tied to those gains ate part of the win.
What is scheduled next
The Fed's September meeting is 2 weeks out and rate-hike odds stand at 60%. If you want to know whether your borrowing costs are about to jump, watch the 10-year yield for any push toward 5%. And watch tanker traffic through the Strait of Hormuz, where shipping delays already cost $500,000 a day. If that number keeps climbing, $90 oil is not the ceiling.
