Brent crude surged past $104 as Iran blockaded the Strait of Hormuz and Houthi rebels captured Perim Island and the port of Mokha, choking the Bab al-Mandeb. Saudi Arabia's 7-million-barrel-per-day East-West pipeline was knocked offline by drone strikes, creating a structural supply constraint. Oil prices jumped 20% for the month, with a 9.5% weekly increase to $104.61.

Semiconductors rallied with ARM up 9% to $264.79, Marvell 13% to $236.10, Intel 12% to $102.94, and AMD 13% to $516.13. The VIX plunged 11% to 15.84, its lowest level this week, as the market priced in a soft-landing bet. However, this move was driven by collapsing volatility, not new fundamentals.

The Fed meets Wednesday with an 87% chance of a 25-basis-point hike priced in. August core CPI ran at 0.3% month-over-month, above the 0.2% forecast. The 10-year Treasury yield sits at 4.83% with only 39 basis points over the 2-year, a nearly flat curve indicating the bond market's distrust of the economy's ability to absorb higher rates.
The week that was
Brent crude climbed 9.5% on the week to $104.61, up 20% for the month, driven by a simultaneous squeeze at the world's two most important maritime chokepoints: the Strait of Hormuz and the Bab al-Mandeb. The capture of Perim Island and the port of Mokha by Iran-backed Houthis gave them control over the Red Sea's southern gateway. As a result, Saudi Arabia's East-West pipeline was shut down after drone attacks from Iraq, leading to a structural supply constraint. Gasoline futures rose, and the national average at the pump hit $4.22 a gallon on September 8, with diesel at $5.94.
While oil prices surged, equity volatility declined, with the VIX dropping 11% in Friday's session alone to 15.84. This divergence between commodities and equity options is a key tell for the week. The low volatility allowed the semiconductor rally to amplify, driven by the sector functioning as a liquid hedge against a 4.83% 10-year yield and $100 oil.
The bond market priced in the potential consequences of the oil shock, with the 10-year Treasury yield closing Friday at 4.83% and the 2-year at 4.43%, a spread of just 39 basis points. This nearly flat curve is a classic late-cycle flattening that historically precedes a recession or a policy error. The 10-year breakeven inflation rate sits at 2.4%, modestly above the Fed's 2% target.
Central banks took different approaches to addressing economic challenges. The ECB hiked its deposit rate to 2.5% on September 10, citing inflation at 3.3% in August and upgrading growth forecasts. In contrast, the Bank of England is expected to hold its rate at 3.75% on Thursday, despite a 6-3 "hawkish hold" split in July.
The big question this week
Will the Fed hike into an oil shock and invert the yield curve, or accept above-target inflation to avoid a recession?
This question is at the heart of current market dynamics. The VIX at 15.84 is not calm, it's the market pricing a Fed that has already lost control of the oil-to-yield transmission.
Brent at $104.61 after a 20% monthly surge is a sustained energy shock, not a blip. The 10-year at 4.83% with only 39 basis points over the 2-year is a nearly flat curve. The Fed's own minutes show officials stressing inflation remains above target.
The chain runs: commodities → inflation → rates → bonds → equities → plumbing. Oil at $100 feeds into gasoline, diesel, jet fuel, plastics, freight, the input cost of everything.
Core CPI at 0.3% month-over-month shows the pass-through has started. The Fed sees this. Chairman Warsh's Jackson Hole speech was hawkish; three governors dissented for a hike in July.
A hike this week doesn't solve the oil problem. Monetary policy works with a 12-18 month lag; raising rates today doesn't unblock the Strait of Hormuz or restart the East-West pipeline.
It does, however, raise the cost of capital for the semiconductor buildout that's been the market's only leader. Marvell, ARM, Intel, AMD, their capex is funded at floating rates. A hike tightens the very trade that's been holding the index up.
The 10-year-2-year spread at 39 basis points is the battleground. If it inverts, the market is pricing a policy error, the Fed hikes, the economy cracks, and the VIX at 15.84 is a coiled spring. The second-order effect: a hawkish Fed strengthens the dollar further, squeezing multinational earnings and turning the semiconductor rally into a crowded short.
The week ahead
Wednesday, September 16, FOMC rate decision, Economic Projections, Statement, and Press Conference (2:00 PM ET / 2:30 PM ET). Markets price an 87-88% chance of a 25-basis-point hike to 3.75-4.0%. The dot plot will show whether officials see this as "one and done" or the start of a longer path. The press conference with Chairman Warsh will be parsed for any acknowledgment of the oil shock.
Thursday, September 17, Bank of England rate decision (7:00 AM ET). The MPC is expected to hold at 3.75%. But the 6-3 split in July and Governor Bailey's pushback against market pricing for aggressive tightening create asymmetry: if the BOE sounds more dovish than the ECB or Fed, sterling weakens and EUR/GBP breaks higher.
Thursday-Friday, September 17-18, Bank of Japan policy meeting. Widely expected to raise the policy rate to 1.25% from 1.0%, continuing gradual normalization. Governor Ueda has said the BOJ is "coming quite close" to its 2% inflation target.
Monday, September 14, Canada CPI (8:30 AM ET). Forecast: -0.1% month-over-month vs +0.5% prior. A cooler print gives the Bank of Canada room to cut; a hotter one forces the BoC to keep rates restrictive while the Fed hikes.
Wednesday, September 17, New Zealand GDP (6:45 PM ET). Forecast 0.1% quarter-over-quarter vs 0.8% prior. A sharp slowdown would reinforce the RBNZ's easing bias and weigh on the kiwi.
Earnings: FedEx (FDX) reports Wednesday. The logistics bellwether will give a real-time read on global trade volumes, especially relevant with Red Sea and Hormuz disruptions. Consensus EPS $4.21 on $23.2 billion revenue.
Worth knowing: Leverage and margin calls
High leverage and potential margin calls characterize current market dynamics. Imagine a hedge fund putting up $10 million and borrowing $90 million to buy $100 million of semiconductor stocks. That's 10-to-1 leverage, borrowed conviction.
If the position rises 10%, the fund makes $10 million on its $10 million equity: a 100% return. But if it falls 10%, the equity is wiped out. The prime broker issues a margin call: post more collateral or sell. The fund sells, pushing prices down and triggering more margin calls.
This mechanism is always the same: leverage hides in calm markets and reveals itself when the tide goes out. Remember the yield-price seesaw: when yields rise, bond prices fall. Leveraged holders of long-duration Treasuries faced margin calls in 2022 as the 10-year went from 1.5% to 4.2%. A short squeeze is the mirror image of a margin-call cascade.
Right now, the VIX at 15.84 suggests investors have sold volatility to fund long equity exposure, particularly in semiconductors. The low volatility is a positioning artifact, not a fundamental all-clear. If the Fed hikes Wednesday and the 2s10s spread inverts, the VIX will spike. Leveraged long semis / short vol books will get margin-called, forcing selling that will hit the most crowded trade first: the chip rally.
Concept 57 of 83 in the Fair Value course.
Tomorrow's question: Canada CPI month-over-month is forecast at -0.1% (prior +0.5%). If the print comes in above forecast, say, +0.2%, which way does the 2-year Canadian yield move, and why?
