Who decides when a recession has officially started?

In the US, no government agency does. A committee of eight academic economists at a private nonprofit, the National Bureau of Economic Research, names the month a recession began. It does not use the 'two quarters of falling GDP' rule, and it names the month only after the fact, often many months later.

In 2022 the economy shrank for two quarters, and no recession was called

In the summer of 2022, the US government reported that the economy had shrunk two quarters in a row. Output fell at an annual rate of 1.6 percent in the first quarter and 0.9 percent in the second, a figure later revised to 0.6. Many people believe that is what a recession is, and the headlines said so.

The body whose verdict on US recessions counts did not declare one. It issued no statement on the question at all. Meanwhile, the monthly measures it watches, jobs among them, were still rising. Two years later, in September 2024, the government's statisticians finished their regular annual revision of the numbers. The second quarter of 2022 now showed growth of 0.3 percent instead of a decline, while the first quarter stayed negative. One of the two falling quarters had disappeared.

So the rule most people would quote with confidence is not the rule. Two falling quarters are a quick signal that is available early, not the test that dates a recession. To see what the test is, you have to know who makes the call.

One of 2022's two falling quarters turned into growth · US output in the second quarter of 2022, annual rate, in percent · Summer 2022 · -0.9 · First reported · September 2024 · 0.3 · After the annual revision · An earlier revision put it at -0.6. The first quarter, at -1.6, stayed negative.

Eight economists at a private nonprofit, not a government agency

The official dates of US recessions come from the National Bureau of Economic Research, a private, nonprofit research organization. Inside it, a small group called the Business Cycle Dating Committee decides the month the economy peaked and the month it hit bottom. The span between those two months is what counts as a recession.

The committee in its current form was set up in 1978. It has eight members, all academic economists, from Stanford, MIT, Northwestern, UC Berkeley, Harvard and Princeton. One of them, Robert Gordon, has been on it since the start. Robert Hall chaired it for 46 years, until Valerie Ramey took over in 2024.

No law gives the committee this job, and the US government publishes no rival set of dates of its own. The committee's dates count because, over decades, the government, the press and researchers have chosen to rely on them. 'Official' here means widely accepted, not legally binding.

What the committee looks at instead of a single GDP number

The committee defines a recession as 'a significant decline in economic activity that is spread across the economy and lasts more than a few months.' That definition has three tests : how deep the fall is, how widely it spreads, and how long it lasts. The tests can offset one another, so an extremely sharp fall can count even if it is brief.

It does not lean on one quarterly figure. Among the measures it watches most closely are six monthly ones : income after removing government transfers and adjusting for prices, jobs counted from employers' payrolls, jobs counted from a household survey, consumer spending, sales by manufacturers and traders, and factory output. These are not a fixed checklist, and they are not weighted equally. What the committee does weigh equally is a pair of measures of the whole economy's output that should match in theory but often don't, one built from what is spent and one from what is earned.

Because of this, the committee's calls and the two-quarter rule can disagree in either direction. In 2022 there were two falling quarters and no recession. In 2001 there was a recession, yet output never fell for two quarters in a row.

The two-quarter rule and the official call disagree both ways · Two US years, by the rule and by the dating committee · Two falling quarters in a row · Recession dated by the committee · 2022 · 2001 · Yes · No

Why the official dates can come more than a year late

The committee waits until there is enough evidence that the economy turned, and it allows time for the standard revisions to the main statistics. As 2022 showed, early figures can change sign. Calling a turn too early risks having to take it back.

In the past, the gap between a turning point and its announcement has run from 4 to 21 months. The quickest call came in June 2020, when the committee said the economy had peaked in February 2020. The slowest was for the end of a recession, not its start : in December 1992, the committee said the recession that began in 1990 had ended in March 1991. The end of the short 2020 recession, in April 2020, was announced only in July 2021, 15 months later.

So by the time a US recession has an official start date, people have usually been living through it for months, and sometimes it is already over.

The official call has come 4 to 21 months after the turn · Months between a US turning point and the committee's announcement · 2020 peak (February 2020) · End of 2020 recession (April 2020) · End of 1990 recession (March 1991) · 4 months · 15 months · 21 months · The longest wait was for the end of

Japan and Korea leave the call to the government, and wait even longer

In Japan, the official dates are set by the head of a research institute inside the Cabinet Office, after a panel of outside experts discusses them. Its three tests are close to the American ones : how widely the change spreads, how large it is, and how long it lasts. Japan's last full cycle peaked in October 2018 and hit bottom in May 2020. The peak was set provisionally in July 2020 and the bottom in November 2021. Both dates were confirmed in July 2022, more than two years after the bottom.

In Korea, the national statistics agency, now called the National Data Office, sets the dates through a committee of the national statistics council. It looks at an index of current activity, production, consumption, GDP and the wider economic situation, and tests whether a turn is clear, widespread and lasting. The bottom of May 2020 was set provisionally only in March 2023, almost three years later. At the time, the agency said more evidence was needed before naming the next peak, and it has not been named yet. According to a May 2026 news report, the agency plans to announce it after a council review at the end of 2026, a plan the agency has not yet confirmed in an official release.

The contrast runs against what many would guess. For the same 2020 downturn, the US handed the call to a private group and got it sooner. Japan and Korea keep it inside government, use very similar tests, and took longer.

In the euro area, the two-quarter rule lives mostly in the headlines

The euro area has no official body that applies the two-quarter rule. Its recession dates come from a committee of five researchers at the Centre for Economic Policy Research, a private network of economists, which follows the American model. Unlike the US committee, it dates turns by quarter rather than by month.

That committee says a recession is usually visible in two or more quarters of falling output, jobs and other measures, but that this is not a fixed rule. In June 2023, euro area output had dipped slightly for two quarters in a row in revised data. Employment kept growing and unemployment hit a record low, and the committee did not call a recession.

The two-quarter rule is quick and easy to apply, and it is available long before any committee decides, which is why news reports and commentators use it widely. It is a useful early signal, not the official measure.

An official recession date is a label for history, not an alarm

Everywhere this is done carefully, the official start of a recession is decided by looking back, once the data has settled. It records what happened. It is not a warning of what is happening now.

As of October 2026, the US committee has not dated a new peak since the bottom of April 2020. A widely used data series kept by the St. Louis Fed and based on its dates shows no recession in any month through September 2026. That only means no recession has been dated yet. If one has begun, its start date would come later.

Alpha · claude-sonnet-5

This confirms the manuscript's backbone solidly. Here is what I found, as participant Alpha. The central claim — NBER, not government, dates US recessions via depth/diffusion/duration, not GDP-two-quarters — holds up completely. The NBER's own FAQ states plainly: "Most of the recessions identified by our procedures do consist of two or more consecutive quarters of declining real GDP, but not all of them. In 2001, for example, the recession did not include two consecutive quarters of decline in real GDP." It further explains the mechanics: "we do not identify economic activity solely with real GDP, but consider a range of indicators... we consider the depth of the decline... our main focus is on the monthly chronology... we give equal weight to real GDI". That's the manuscript's three-D framework and six/dual-indicator description, verified at the source (nber.org/research/business-cycle-dating/business-cycle-dating-procedure-frequently-asked-questions). On the 2022 GDP-revision claim — the manuscript's framing is accurate but its own uncertainty flag was right to worry. BEA's own 2024 annual-update summary says it directly: "The revisions did not change the direction of c…

The answer to the reader’s question is jurisdiction-dependent. In the United States, the National Bureau of Economic Research’s Business Cycle Dating Committee—the eight economists currently listed by the NBER—dates recession peaks and troughs. It is a private body, not a government agency. Its dates are *quasi-official* because they are widely adopted, not because a law makes its decisions binding. The NBER says the US government publishes no competing business-cycle chronology. The committee judges the depth, breadth and duration of a decline rather than applying an automatic two-quarter GDP test. (nber.org) I agree with Alpha that the premise stands, but would not clear every sentence unchanged: | Manuscript claim | What the sources establish—and what to change | |---|---| | Eight economists; committee established in 1978; Hall succeeded by Ramey in 2024. | Supported by the NBER’s members list and [FAQ](https://www.nber.org/research/business-cycle-dating/busine…

[Gamma]: Building on the solid foundation Alpha and Beta have laid, I will address the remaining unverified claims to finalize our check of this manuscript. I focused my budget on the European and Korean claims, as well as refining the NBER 2022 narrative. Here is what the record shows for the final pieces of the manuscript: On the CEPR (Euro Area) and the June 2023 call: The manuscript's characterization of the Euro Area Business Cycle Dating Committee is structurally accurate. It is a private network committee (supported by the EABCN), and its methodology explicitly looks beyond a strict two-quarter GDP rule, noting that a recession is *usually* visible in GDP, employment, and other measures. Regarding June 2023: committee releases from that summer and early fall note that while the euro area economy and manufacturing output remained weak, economic activity was "supported by the strength of the labour market," with unemployment hitting historical lows (6.4% in August 2023). The committee did not declare a recession. The manuscript's claim here is sound, though as Beta noted, it should specify "euro area" rather than generalizing to all of "Europe." On Korea's dating prac…

Verification Findings 1. US Recession Dating & the 2022 GDP Revisions * Claim: The National Bureau of Economic Research (NBER), a private nonprofit with an 8-member Business Cycle Dating Committee (chaired by Valerie Ramey following Robert Hall, with Robert Gordon serving since 1978), dates US turning points using depth, diffusion, and duration rather than an automatic "two consecutive quarters of falling GDP" rule. * Status: Supported. * Evidence: The NBER Business Cycle Dating Committee page (nber.org/research/business-cycle-dating/business-cycle-dating-committee-members) lists 8 academic members, Valerie Ramey as chair, and Robert Gordon's tenure since inception in 1978. The NBER FAQ (nber.org/research/business-cycle-dating/business-cycle-dating-procedure-frequently-asked-questions) explicitly confirms the "three Ds" (depth, diffusion, duration), tracks 6 monthly indicators alongside equal weight on real GDP/GDI, and confirms historical announc…

The Arbiter · gpt-6-sol

Round record for the publication check: Alpha, Beta, Gamma and the Researcher agree that the manuscript’s central premise stands: in the United States, the private NBER Business Cycle Dating Committee dates peaks and troughs using evidence about the depth, breadth and duration of changes in activity, not an automatic two-quarter GDP rule. “Official” should mean the chronology widely relied upon, not a government decision with legal force. The NBER’s FAQ supports the eight-member committee’s method, its use of monthly indicators alongside real GDP and GDI, and its example of a 2001 recession without two consecutive quarters of falling real GDP. Its six monthly measures should not be presented as an exhaustive, equally weighted checklist. (nber.org) The 2022 example survives, with an attribution correction. Alpha and the Researcher found BEA’s September 2024 revision of 2022 Q2 real GDP from −0.6% to +0.3%; Q1 remained negative. But Beta and Gamma identified no 2022 committee statement saying jobs were growing and therefore there was no rece…

The Arbiter's Final Verdict · gpt-6-sol

In the United States, the National Bureau of Economic Research’s Business Cycle Dating Committee decides the dates that are generally treated as the official recession chronology. It is a private research organization, not a government agency. The committee identifies the month economic activity peaked—the start of a recession—and the month it reached a trough—the end. Its authority comes from widespread acceptance of its dates, not from a law giving it the power to declare recessions. NBER committee and members The committee looks for a significant decline that is deep, widespread and lasting, drawing on monthly measures of employment, income, spending, sales and production, as well as GDP and gross domestic income. Two consecutive quarters of falling GDP are not an automatic test. The 2001 recession did not meet that shortcut; conversely, the committee did not date a recession in 2022 despite the two negative GDP quarters initially reported. A later BEA revision changed 2022’s second quarter…
