Five sessions, three central bank decisions, a failed crypto bill, and the second-largest options expiration on record. The week of September 14-18 packed in more than most traders can hold in their head at once, so here is what actually moved money and what was just noise.
What did the Fed, the ECB, and the Bank of England each decide this week?
The Fed hiked 25 basis points to 3.75-4.00% on Wednesday, its first hike since 2023. The ECB had already hiked on September 10. The Bank of England held, but only barely, on a 6-3 vote.
The Fed's move was unanimous, 12-0, and the first increase in three years. The Federal Reserve's press release is the primary record. Four days earlier, the European Central Bank raised its main refinancing rate by 25 basis points to 2.65% (deposit facility to 2.50%), its second hike of 2026, citing inflation pressure tied to Middle East shipping disruptions. The Bank of England held at 3.75% on a 6-3 split, with three dissenters pushing for a hike to 4.0%.
Three central banks, three different paths, in the same five trading days. That divergence is the actual story. The Fed and ECB are both now hiking into inflation that is not falling as fast as forecast, while the BoE is stuck between a weakening UK economy and CPI still running at 3.1%.
How high did the 10-year Treasury yield get, and why does that matter more than the Fed decision itself?
The 10-year touched 5.04% this week, its highest level since 2007, before settling near 4.94-4.95% by Friday.
A Fed hike is a known, scheduled event. A 10-year yield breaking a level it has not touched in nineteen years is not. Treasury market data this week showed the 10-year briefly exceeding the 2007 high before pulling back roughly 10 basis points into the weekend. Long-end yields move on growth and inflation expectations decades out, not on any single FOMC statement, so a spike to a multi-decade high says more about how the bond market is pricing sustained inflation risk than the 25bp hike itself does.
What happened during Friday's triple witching, and did $7 trillion in options actually move the market?
Roughly $7 trillion in options notional expired Friday, the second-largest triple witching on record, and the S&P 500 still closed up 1.1% on the day.
Bloomberg reported the expiration covered close to a quarter of the market. The S&P 500 closed at 7,637.76, up 85.95 points. But the daily print hides the weekly one: the S&P 500 actually finished the week down 0.08%, the Dow lost more than 1.5%, and the Nasdaq gained 2.6%, according to Friday's market wrap. Big options expirations get blamed for volatility, but this one landed on a day the index rallied. The VIX closed at 14.81, down from a prior close of 15.44, not the spike a $7 trillion unwind might suggest.
Why did oil spike above $108 and give almost all of it back by Friday?
Oil topped $108 a barrel on September 14 on supply-shock fears, then fell to $99.53 by Friday's close, a 2.34% single-day drop that erased most of the week's gain.
The move traces to the same Middle East tension the ECB cited for its own hike. Crude spiked hard early in the week, then gave back the move by Friday, settling under $100 for the first time in days. A four-day round trip of this size is a reminder that a geopolitical oil spike without a confirmed supply disruption tends to fade once the initial fear premium gets priced out.
What happened to bitcoin and the CLARITY Act, and what does it mean for crypto?
The Senate blocked the CLARITY Act on a 50-49 cloture vote Tuesday, and bitcoin has spent the rest of the week chopping in the low-$80,000s without a clear policy tailwind.
The cloture vote fell 50-49, 11 votes short of the 60 needed to open debate, with every Democrat opposed and four Republicans joining them over an ethics provision on officials profiting from crypto ventures. Bitcoin was trading near $80,900 as of this weekend, a level it has held through the bill's failure without much reaction either way. That is arguably the more interesting fact: a market structure bill dying in the Senate used to move crypto prices hard. This time it barely registered.
What's on the calendar for the week of September 21-25?
The next full week brings the Chicago Fed National Activity Index Monday, Richmond Fed manufacturing and a $78 billion 2-year Treasury auction Tuesday, and flash PMIs for the US, UK, Germany, and the eurozone midweek.
There is no CPI print until October 14, leaving close to a five-week data gap before the next FOMC meeting on October 27-28. Earnings-wise, AutoZone reports Tuesday premarket, Paychex and General Mills report Wednesday premarket with Cintas after the close, Darden reports Thursday premarket, and Costco and BlackBerry report Thursday after the close. With the data calendar this thin, positioning ahead of the next CPI print and the October FOMC meeting is likely to matter more than any single release next week.
