Notes:

The Bristow-Hall Rule signals the start of a recession when a labor-supply object crosses its line — the insured unemployment rate rising off its low, the survey-week insured rate rising off its low, initial claims rising off their base (the higher of their 52-week low and 85 percent of their five-year median, so that a return from an unusually low level is not read as a turn), the share of states with the insured rate up, or the Sahm gap with vacancies already falling — and a demand-side object confirms it inside a window of six months back and four months forward: the vacancy rate off its four-month high, factory hours and nondurable employment both falling, housing starts and the unemployment rate both moved, housing starts and the vacancy rate both moved, or the commercial paper spread widened (the wider of the two paper markets the Federal Reserve reports, financial and nonfinancial, over the three-month bill). A proposal by the insured unemployment rate or by initial claims that stands only a little above its line — within 0.2 point for the insured rate, within 15 points for claims — also needs a co-signer from the household survey: the three-month average of the unemployment rate, as last published, at least 0.2 point above its low of the prior twelve months; a proposal further above its line needs none. A sudden stop is read the same week it happens: a single week of initial claims 35 percent or more above the claims base, with the S&P 500 20 percent or more below its high of the prior twenty trading days at the last close before the release, opens a recession on the day of that release. A reading equal to its line is at the line. It signals the end of a recession when the three-week average of initial claims has fallen from its peak for three weeks running and the S&P 500 stands above its six-month low the same week (or continued claims or the insured unemployment rate stand below their peaks). A recession is dated the month the rule fired, at both ends.

The indicator is the rule's reading on one line, with an observation on every day a release the rule reads arrives: each proposing object paired with its confirmers, read as the smaller of the proposing object's ratio to its line (the largest over the last four months) and its best confirming object's ratio to its line (the largest over the last six months), and the strongest pair taken — the rule's own window, read backward, so that every value uses only what had been published by that day. Below 1.00 the rule is silent and the value is its distance to the next call; a proposing object that has already fired counts as zero until it has re-armed, since it cannot call again before then. From the day the rule opened a recession through the day it closed it, the line stands at or above 1.00 and the value is the reading without arming, so the height is the strength of the rule's objects during the recession; it drops below 1.00 at the first release after the close. Where a reading and the rule's own call disagree — under the line while a recession stayed open — the line is held at 1.00. Nothing is smoothed and nothing is capped: the crossings are the rule's own calls and the heights are its readings.

The indicator is based on "real-time" data, that is, each series as it stood on its release day: weekly claims as first published by the Department of Labor; the unemployment rate, hours, employment, housing starts and job openings read, for each month, from the whole series as it was published on the day that month's figure first appeared, so that every earlier month enters at the value then current and not at its own first print; the paper and bill rates from the Federal Reserve's H.15 release and the S&P 500 daily close, which are never revised. The series begins in January 1962, the first January at which the rule's lines were chosen from the past alone; from then through January 2026 they were re-chosen each January using only the recessions that had been dated and announced by then, so every call on this page was made blind. The lines chosen at the last of those Januaries are now fixed and are not re-chosen again. The recessions before 1962 were used to choose the lines and are not shown. Shaded areas are the recessions dated by the NBER's Business Cycle Dating Committee; the lined area is the recession the rule dated and the NBER has not, June to September 2024. Each object is carried at the day it was published — each weekly claims object on the day of the Department of Labor release that carried it (the Thursday after the week, or the Wednesday before a Thursday holiday; the insured rate runs a week behind initial claims and the state rates two weeks behind), the employment report on its day, JOLTS and housing starts on theirs, the H.15 week on the first business day after its Friday, when the Federal Reserve posts Friday's rates — and the line is rebuilt on each of those days, by a job that follows the release calendar; the next releases are listed above.

Citation:

Each row is a recession; the axis is months after the turn (the peak month on the left, the trough month on the right). The blue dot is the day the rule fired, which under the rule is also the date it gives the turn; the green square (peaks) is the day the Sahm rule crossed 0.50 in real time (FRED's SAHMREALTIME series), the release day of the month that crossed; the black diamond is the day the NBER announced its date. Before 1980 the NBER's announcement is taken as the first issue of the Commerce Department's Business Conditions Digest that carried the date. Point at a marker for the exact dates.
