THE WEEK
The same step three times
S&P 500 7,650.50 · −6.48 · −0.08% · Friday to Friday
The Federal Reserve raised interest rates on Wednesday afternoon for the first time since 2023, and the S&P 500 finished the week six and a half points from where it started. It did not get there quietly. The index came down to the decision in three steps of almost exactly the same size — thirty-seven points on Monday, thirty-four and a quarter on Tuesday, thirty-three and ninety-two hundredths on Wednesday, the three of them inside 3.08 points of one another, which is the most uniform three-day run the index has produced all year. Then Thursday took back eighty-five and ninety-five hundredths of it and Friday another twelve and three-quarters, and the week closed at 7,650.50 against the 7,656.98 it had opened from. Eight hundredths of one percent. Of the thirty-seven weeks of 2026 that ran four sessions or more, no other finished this close to where it began. Inside those five days: a quarter-point rise voted twelve to nothing, a ten-year Treasury yield through five percent on Wednesday and through it again on Friday, roughly seven trillion dollars of options coming off the books in the second-largest expiry ever recorded, and one hour on Wednesday afternoon, between half past two and half past three, in which the index fell a hundred and four points while the chairman took questions. Seven tenths of everything the week ever lost, measured from where it started down to its lowest print, was made in that single hour. Everything after it was the way back.

The week's protagonist
The quarter point — no symbol.
Move: 3.50–3.75 percent to 3.75–4.00 percent, voted twelve to nothing at two o'clock on Wednesday — the first rise in the price of money since 2023, and by Friday's close the index stood 6.48 points from where it had been before anybody knew
A weekly page can say one thing a daily cannot, and this week the thing it says is that the market spent three days pricing a quarter point, one hour receiving it, and two days giving the whole move back. The three days down are the part worth keeping. Monday took 37.00, Tuesday 34.25, Wednesday 33.92 — a spread of three points and eight hundredths between the largest and the smallest, on an average of thirty-five. Of the forty-two runs of three consecutive same-direction sessions in 2026, that is the tightest there has been, both in points and as a fraction of its own size; the second tightest by that measure is the three-day fall in the week immediately before this one, which was more than twice as ragged. For three sessions the index went down at what looked like a set rate. On Wednesday at two o'clock the Committee raised the target range a quarter point, unanimously, and the index did nothing with it: between 14:00 and 14:10 it ran up twenty-four points and back and finished the bar roughly where it had begun. The words alone did not settle anything. What settled it was the hour that followed. From 14:30, when Kevin Warsh began taking questions, to 15:30, the index fell from 7,612.01 to 7,507.77 — 104.24 points, and the low of the week. Measured from the 7,656.98 the week started at, the index lost 149.21 points top to bottom, and 104.24 of them were made in those sixty minutes. Then it stopped. Thursday opened 79.63 higher than Wednesday closed and never traded back down through the gap; the 390 minutes of Thursday's regular session added 6.32 more, so almost the whole of the best day since the tariff-pause window was made while nobody could buy it. Friday's opening print, 7,657.17, was nineteen hundredths of a point above where the week began — the only moment in five sessions that the index was not down on the week — and it never got there again. Add the five overnight gaps together and they come to +61.34. Add the five daytime sessions together and they come to −67.82. Each of those is roughly ten times the size of the week, and they point in opposite directions. The volatility index made the same shape: 15.84 the Friday before, up for three sessions to 17.71 on the decision, then 15.44 and 14.81, finishing the week of the first rate rise in three years a full point below where it started. The whole structure of the week is a thing that happened and then unhappened, and the only permanent record of it is that money now costs a quarter point more.
The ledger — what actually happened
| Measure | Close | Change | Marginalia |
|---|---|---|---|
| The week | 7,650.50 | −6.48 · −0.08% | 7,656.98 at Friday, September 11, 2026's close to 7,650.50 at this one. Monday −0.48, Tuesday −0.45, Wednesday −0.45, Thursday +1.14, Friday +0.17. Computed from the five days' closes |
| Best day | Thursday +1.14% | “Everything before nine-thirty” — 7,637.76, +85.95 | |
| Worst day | Monday −0.48% | “Pace yourselves” — 7,619.98, −37.00 | |
| Up and down | 2 · 3 | 2 sessions rose and 3 fell. The risers were worth 98.69 points between them, the fallers 105.17; the difference is the week | |
| Three steps of one size | −37.00 · −34.25 · −33.92 | Monday, Tuesday and Wednesday, three points and eight hundredths between the largest and the smallest on an average of 35.06. Of the forty-two runs of three consecutive same-direction sessions in 2026 this is the tightest, in points and as a share of its own average (8.79 percent); the next tightest by share, at 18.72 percent, is the three-day fall in the week immediately before this one | |
| The flattest week of 2026 | −0.0846% | first of the thirty-seven weeks of 2026 that ran four sessions or more, computed from the closes. Second is 31 August – 4 September at +0.0887 percent, which is the week this site mocked its first weekly page on; third is 2–6 February at −0.0970 | |
| The high | 7,657.17 | Friday's opening print, and the only moment in five sessions the index stood above where the week began — by nineteen hundredths of a point. Inside that same minute it was at 7,641.93, and in the 390 minutes that followed it never came back | |
| The low | 7,507.77 | Wednesday at 15:27, 149.21 under the line, made while the chairman was taking questions. It is the lowest the index has traded since 31 July | |
| One hour on Wednesday | −104.24 | 14:30 to 15:30, from 7,612.01 to 7,507.77, across the press conference. That single hour is 69.9 percent of everything the week lost from its starting line to its lowest print | |
| The range | 149.40 | points, top to bottom — 1.95 percent of where the week began, to finish 0.08 percent under it. Friday holds the high end and Wednesday the low, and the close sat 95.5 percent of the way back up | |
| Overnight and daylight | +61.34 · −67.82 | the week's five gaps between sessions are worth +61.34 points together; the five sessions themselves −67.82. Each is about ten times the size of the week, and they point opposite ways. Thursday alone carried +79.63 of the overnight | |
| The decision | 3.75–4.00% | a quarter-point increase, unanimous twelve to nothing, the first rise since 2023. The statement said inflation remains elevated and that the action would support a timelier return to the Committee's 2 percent goal | |
| The ten-year | 5.004% | through five percent after Wednesday's decision at about 5.008, back under it on Thursday at 4.951, and back above it on Friday. Twice through five in four days, at the highest levels since 2007 | |
| Volatility | 15.84 → 14.81 | the same shape as the index and it finished lower: 17.10 Monday, 17.20 Tuesday, 17.71 on the decision, then 15.44 and 14.81 — the lowest close since 4 September. Whatever arrived for the meeting left within two sessions of it | |
| Against the record | −1.90% | Friday's close against the August 13 record close of 7,798.99 (“The flash that stayed”). Wednesday's close was 3.17 percent under it, the furthest the index has been from the record since it was set | |
| The protagonists | 5 days, 4 names | CrowdStrike on Monday, an all-time closing high on an essay · Coinbase on Tuesday, −10.10 percent on a Senate vote that failed 49 to 50 and needed sixty · Goldman Sachs on Wednesday, −3.91 on the day the Fed raised · Intel on Thursday, +7.62 · Coinbase again on Friday, +11.66 to 194.25 and back above its pre-vote close, 48 hours after the SEC granted by exemption what the Senate had refused. Of the forty-five weeks in this book that carry a named protagonist, only three have ever repeated one: GameStop across 27 and 28 January 2021, Nvidia across 25 and 27 August 2026, and this week |
The week's pigment
Coat jade — the hedge that did no work. The driver's coat in the week's own photograph, lifted out of the car's shadow into daylight. Puts is the clown of the hedge and he is the one at the wheel this week, with his umbrella furled and standing between the seats under a completely clear sky — which is what a week like this one does to insurance. Set on a near-black with green in it. Quiet on purpose, like the week before it: this page carries five days' pigments in a row beneath it, and the week's own colour has to stand behind them rather than among them. Distance declared honestly, as the ledger now requires: ΔE 7.67 to its nearest neighbour in the 391 hexes of the book (Undertow celadon, 2026-08-06), and no closer than 28.64 to any of the five day accents that sit under it on this page.

Every number on this page is taken from those entries or is arithmetic on their closes and opens; the week verifies nothing they did not already verify against the feed. The two rankings — the tightest three-day run of 2026, and the flattest week of 2026 — are computed over the feed's daily closes for every 2026 session, and are stated on closes alone because the feed's daily opening values disagree with the published ten-minute opens on 36 of the 78 days this site has authored.
