Factual claim · Statement 2 of 42 · Strong evidence
Accounts of the 19 October 1987 crash, including the March Gallery summary and IG's history, describe a chain reaction that caused stock exchanges across the globe—Hong Kong, London, Berlin, New York—to plunge within hours, with the Dow falling about 22 percent.

Factual claim
In the United States, the Dow Jones Industrial Average (DJIA) dropped 22.6 percent in a single trading session.
Investopedia confirms Black Monday on Oct. 19, 1987 saw the Dow lose 22.6% in a single trading session and notes that in percentage terms it is the biggest-ever one-day stock-market loss, and it 'remains the largest one-day decline ever.' An SEC speech and the Federal Reserve History essay likewise describe the 22.6% DJIA drop as the largest one-day stock market decline in history.

Factual claim · Statement 4 of 42
The Federal Reserve History essay on the 1987 crash states that the 22.6 percent one-day Dow drop on Black Monday (October 19, 1987) 'also marked the sharpest market downturn in the United States since the Great Depression.' An independent investment note from Janney repeats the same characterization, and a New York Times retrospective confirms the 22.6 percent decline was the worst since World War I and far greater than the 12.82 percent drop of October 28, 1929, so the framing holds.

Factual claim · Statement 5 of 42 · Strong evidence
NPR's 30th-anniversary account states that regulators responded to Black Monday with circuit breakers allowing exchanges to temporarily halt trading during exceptionally large price declines, and Investopedia and CEPR likewise list circuit breakers among the reforms adopted after the 1987 crash. Together they confirm the claim that the crash prompted exchange trading-pause provisions as part of a broader reform package.

Factual claim · Statement 7 of 42
The Federal Reserve History essay states that stock markets raced upward in the first half of 1987 and notes the Dow Jones Industrial Average gained 44% by late August, while contemporaneous LA Times and Chicago Tribune accounts describe the strong January-to-August 1987 surge.
These links belong to the claim, but no exact sentence was found on their pages. Review the sources before relying on this result.
Factual claim · Statement 8 of 42 · Strong evidence
The Federal Reserve History essay on the Stock Market Crash of 1987 (and its PDF version) states that by late August the DJIA had gained 44 percent in a matter of seven months, stoking concerns of an asset bubble. Other accounts of the 1987 run-up repeat the same 44-percent-over-seven-months figure.
Factual claim · Strong evidence
By late August, the DJIA had gained 44 percent in a matter of seven months.
The Federal Reserve History essay on the 1987 stock market crash states that by late August the DJIA had gained 44 percent in about seven months, stoking asset-bubble concerns, and independent retrospectives of Black Monday (global-macro-monitor and CGAA) repeat the same 44 percent seven-month gain and bubble worries. The historical figures match the claim.
Factual claim · Statement 9 of 42
The Federal Reserve History essay on the 1987 stock market crash states that in mid-October a storm cloud of news reports undermined investor confidence and led to additional volatility, citing the larger-than-expected trade deficit and falling dollar. Gallup's reproduction and a Carver Financial Services summary repeat the same mid-October sequence, supporting the claim.
This passage repeats the speaker’s own words. It shows the words were said, not that they are true.
Factual claim · Statement 10 of 42
The only search result touching this episode (Gallup's Vault article) simply re-quotes the Federal Reserve's own account — 'The federal government disclosed a larger-than-expected trade deficit and the dollar fell in value' — so it does not independently confirm the underlying October 1987 trade report. All other results concern US trade deficits in 2025–2026 and say nothing about 1987.
This passage repeats the speaker’s own words. It shows the words were said, not that they are true.
Factual claim
The federal government disclosed a larger-than-expected trade deficit.

Factual claim · Statement 11 of 42 · Strong evidence
Wikipedia's account of the 1987 crash describes it as the culmination of a decline that 'had begun five days before on October 14,' with the DJIA falling 3.81% that day, and Nasdaq and Acorns both date the start of the sustained daily losses to Oct. 14, 1987. This is independent corroboration of the Federal Reserve History essay's sentence about markets beginning to incur large daily losses on October 14.
Factual claim · Statement 12 of 42
Investopedia’s Black Monday entry confirms that October 16, 1987 saw the simultaneous expiration of stock options, stock index futures, and stock index options, a phenomenon called triple witching. However, Investopedia’s separate explanation defines triple witching as the quarterly expiration on the third Friday of March, June, September, and December, not a monthly expiration of options and futures; monthly expiration applies to stock options, while index futures and options are typically quarterly.

Factual claim · Statement 14 of 42 · Good evidence
The Federal Reserve History essay states that Treasury Secretary James Baker publicly threatened on Saturday, October 17, 1987, to devalue the dollar to address the trade deficit. The Cato Institute independently says Baker went on TV the weekend before Black Monday and threatened to devalue the dollar over trade, and a contemporaneous New York Times report also describes Baker's threat to push the dollar lower, though it notes earlier Thursday remarks.
Factual claim · Statement 15 of 42
The Federal Reserve History essay on the Stock Market Crash of 1987 describes the October 19, 1987 "Black Monday" sequence exactly this way, noting that markets in and around Asia began plunging before US markets opened and that New Zealand's market fell 60 percent in the most severe case. A secondary summary of that essay repeats the same account. The evidence is largely the same-publisher essay and pages that quote it, so corroboration from independent contemporary reporting is thin.
These links belong to the claim, but no exact sentence was found on their pages. Review the sources before relying on this result.
Factual claim · Statement 16 of 42
The Federal Reserve History account of the 1987 crash states that as Asian markets plunged on the morning of October 19, 1987, additional investors moved to liquidate positions and sell orders vastly outnumbered willing buyers near previous prices, creating a cascade in stock markets. An independent UK government paper on leverage and forced asset sales likewise describes a clear short-run imbalance of sells versus buys on October 19, 1987, tied to evaporating market liquidity.
These links belong to the claim, but no exact sentence was found on their pages. Review the sources before relying on this result.
Factual claim · Statement 17 of 42
The Federal Reserve History essay on the 1987 crash states that "In the most severe case, New Zealand's stock market fell 60 percent," and Wikipedia's Black Monday article independently records that by its February 1988 trough the market had lost 60 percent of its value. New Zealand Geographic likewise reports the market was down almost 60 percent from its peak four months after the October 1987 crash. The 60 percent figure is a cumulative peak-to-trough decline over several months, not a one-day loss.

Factual claim · Statement 20 of 42
In the 1987 period described by the Federal Reserve History essay, Andrew Grove was indeed Intel's chief executive, a post he held from 1987. He stepped down as CEO in May 1998, handing the role to Craig Barrett (remaining chairman until 2004/2005), and he died in March 2016, so the present-tense description no longer holds.
Pikaan found this exact sentence on the publisher’s page. Finding it does not show whether it supports or contradicts the claim.
Factual claim · Statement 21 of 42
An article on the 19 October 1987 market crash identifies Thomas Thrall as a trader at the Chicago Mercantile Exchange who was there that day.
Pikaan found this exact sentence on the publisher’s page. Finding it does not show whether it supports or contradicts the claim.
Factual claim
Thomas Thrall was a trader at the Chicago Mercantile Exchange at the time.
The description comes from the Federal Reserve History essay on the 1987 stock market crash, which calls Thomas Thrall 'a senior professional at the Federal Reserve Bank of Chicago' while noting he was then a trader at the Chicago Mercantile Exchange; a 247wallst article repeats the same wording. No independent record of the title turned up, and the Chicago Fed's current people listing (updated October 2026) shows no Thrall, so whether he still holds that position is unconfirmed.

Factual claim · Statement 22 of 42 · Strong evidence
Multiple independent biographies state Marron became PaineWebber's chairman in 1981 and served as chairman and CEO until the firm's 2000 sale to UBS, so he was chairman during the 1987 period referenced. A 1983 New York Times piece also describes him as "the chairman and CEO" of Paine Webber.
Factual claim · Good evidence
Donald Marron was the chairman of Paine Webber at the time.
A 1983 New York Times profile describes Paine Webber as a long-recognizable brokerage name and one of the most traditional brokerage firms, and company histories place it among the top US brokerage and investment banking houses through the 1980s (about ninth in investment banking in 1985, fifth among brokerages in 1998, fourth-largest US brokerage by 2000). That supports the description of it as a prominent investment firm around the time of the 1987 crash.

Factual claim
International investors had become increasingly active in US markets in the preceding years.
The search results do not directly address whether international investors drove the rapid pre-crisis stock price appreciation. One New York Fed paper discusses international linkages and prior price increases without attributing the appreciation to international investors, and an IMF chapter notes international diversification during the 1980s bull market without establishing causation.

Factual claim · Statement 24 of 42
The SEC's statement calls portfolio insurance a "newly popularized financial product" and TIME notes that by 1987 the funds covered by it had swelled to an estimated $80 billion. A Leland O'Brien Rubinstein case history similarly describes it as growing explosively from 1984 to 1987 and being "one of the hottest money management products of the mid-1980s."
These links belong to the claim, but no exact sentence was found on their pages. Review the sources before relying on this result.
Factual claim · Statement 25 of 42 · Strong evidence
The Federal Reserve History essay on the 1987 stock market crash states that portfolio insurance 'included extensive use of options and derivatives,' and independent sources such as Investopedia and a Federal Reserve Bank of Philadelphia working paper describe portfolio insurance as hedging via index futures, put options, and synthetic option replication.
Factual claim · Strong evidence
Portfolio insurance included extensive use of options and derivatives.
The Federal Reserve History essay on the 1987 stock market crash (Black Monday) states that portfolio insurance 'included extensive use of options and derivatives and accelerated the crash's pace as initial losses led to further rounds of selling.' Independent accounts — including Rick Bookstaber, who helped implement portfolio insurance, and a CNBC retrospective — describe the same mechanical, price-triggered selling loop that deepened the October 1987 decline.
Factual claim · Statement 26 of 42
The Federal Reserve History essay states that stock trades settled after three days while options and futures trades settled after one day. An independent Office of Technology Assessment report also describes disparate settlement periods during the crash, with futures and options settling on a shorter timeline than equities.
These links belong to the claim, but no exact sentence was found on their pages. Review the sources before relying on this result.
Factual claim
At the time of the crisis, stock, options, and futures markets used different timelines for the clearing and settlements of trades.
The search results support the general point that differing settlement timetables create funding gaps and credit/default risk: ESMA notes that T+1 versus T+2 periods can produce a funding gap between purchase and sale, and a 1990 OTA report says longer settlement timetables carry comparatively more risk. However, the cited evidence does not directly establish that those differences created negative trading account balances, so the claim is only partly supported.
These links belong to the claim, but no exact sentence was found on their pages. Review the sources before relying on this result.
Factual claim
At the time of the crisis, stock, options, and futures markets used different timelines for the clearing and settlements of trades.
The search results show that different settlement cycles and lags can create liquidity and counterparty risk, and one Chicago Fed piece notes that late derivatives settlement contributed to gridlock in the 1987 crash. None of the results directly establishes the specific causal claim that differing clearing and settlement timelines created the potential for forced liquidations, so the evidence is insufficient.

Factual claim · Statement 27 of 42
The Federal Reserve History essay states that securities exchanges had no means to intervene against the heavy selling and rapid declines of October 1987, and a Federal Reserve Board working paper documents how record volume overwhelmed exchange systems while NYSE specialists suspended trading in only some individual stocks. A separate SEC study confirms that coordinated cross-market circuit breakers letting exchanges halt trading were not adopted until October 1988, in direct response to the 1987 experience. The only caveat is that exchanges retained narrow, case-by-case powers to delay or suspend trading in individual stocks.

Factual claim · Statement 28 of 42
The Federal Reserve History essay on the 1987 crash states directly that after Black Monday regulators overhauled trade-clearing protocols to bring uniformity to all prominent market products. A separate retrospective also recounts the post-crash push, including the Brady Commission recommendation that clearing systems be unified across marketplaces.
These links belong to the claim, but no exact sentence was found on their pages. Review the sources before relying on this result.
Factual claim · Statement 29 of 42 · Strong evidence
The SEC's 1998 testimony on circuit breakers states that circuit breakers were developed by the securities and stock index futures markets in response to the President's Working Group recommendations after the October 1987 market break, and that exchanges adopted the recommendation and created circuit breaker programs approved on a pilot basis in 1988. The Chicago Fed Letter likewise describes circuit breakers as temporary trading halts designed to interrupt trading during significant market declines, implemented by the NYSE and CME in 1988.

Factual claim · Statement 31 of 42
Wikipedia’s Black Monday aftermath section says the 1987 crash altered implied-volatility patterns used in pricing financial options, and a market analysis notes that out-of-the-money puts were repriced to much higher implied volatilities after October 19 and that Black-Scholes assumptions were shattered. That evidence supports a post-crash recalibration of option valuation, though it describes the change at the market level rather than separately singling out risk managers.

Quote · Statement 32 of 42
A Federal Reserve Board staff history (published 2007) states that before markets opened on Tuesday, October 20, 1987, the Fed issued a statement worded exactly as quoted, and a St. Louis Fed article attributes the same words to "Federal Reserve Board Chairman Alan Greenspan, Oct. 20, 1987." A contemporaneous UPI dispatch from October 20, 1987 likewise reports Greenspan issuing the one-sentence liquidity pledge.

Reported claim · Statement 35 of 42
The YPFS account quotes Bernanke (1990) for the finding that the 10 largest New York banks nearly doubled lending to securities firms in the week of October 19, 1987. But that same account also reports a temporary one-week spike of roughly $2 billion in discount-window borrowing from the Federal Reserve Bank of New York, so the clause that discount-window borrowings 'didn't themselves increase' is at least misleading.

Reported claim · Statement 36 of 42 · Good evidence
The Federal Reserve History essay on the 1987 crash states that some experts argue the Fed's response to Black Monday ushered in a new era of investor confidence in the central bank's ability to calm severe downturns. Independent accounts agree on the substance: an academic paper on the 1987 crash credits Greenspan's liquidity pledge with providing a base of investor confidence, and market commentary notes investors concluded afterwards that the Fed would "pretty much always come to their rescue."
Factual claim · Statement 37 of 42 · Strong evidence
The Federal Reserve History essay states that 'unlike many prior financial crises, the sharp losses stemming from Black Monday were not followed by an economic recession or a banking crisis,' and independent sources corroborate it: a Yale Journal of Financial Crises study notes 'no significant runs on banks and the broader economy did not enter into a recession,' and Goldman Sachs says the US economy 'did not experience a prolonged economic decline after Black Monday.' The San Francisco Fed likewise reports GDP growth was strong in the year after the crash.
Quote · Statement 38 of 42
Kohn's own May 18, 2006 speech at the Federal Reserve Board states, in describing the 1987 crash, that "unlike previous financial crises, the 1987 stock market decline was not associated with a deposit run or any other problem in the banking sector." The Federal Reserve History essay on the 1987 stock market crash quotes the same line and attributes it to Kohn 2006.

Reported claim · Statement 39 of 42 · Good evidence
The Federal Reserve History essay on the 1987 stock market crash records that "some argue that the Fed's response set a precedent that had the potential to exacerbate moral hazard," citing Cecchetti and Disyatat (2010). Independent Federal Reserve commentary, such as the Dallas Fed's 2008 analysis and the Richmond Fed's discussion of precedents set by Fed interventions, likewise describes the argument that rescue actions set a precedent that can encourage additional risk-taking, so the attributed view exists as described.
Factual claim · Statement 40 of 42 · Strong evidence
Investopedia, Britannica, and other independent accounts confirm that in the two trading sessions after the October 19, 1987 crash the Dow regained 288 points — roughly 57% — of its Black Monday losses, and it ended 1987 slightly up. The claim's 'majority' figure matches the documented recovery, though it applies to U.S. Markets, since some international markets took longer to recover.
Factual claim · Statement 41 of 42
Investopedia's account of Black Monday states that in just two trading sessions the DJIA gained back 288 points, or 57%, of the total Black Monday losses, and the Federal Reserve History essay PDF carries the same figure. The math is consistent: 288 points out of the roughly 508-point drop is about 57%.

Factual claim · Statement 42 of 42 · Strong evidence
Investopedia's Black Monday entry states that 'In less than two years, U.S. Stock markets had surpassed their pre-crash highs,' and the Seattle Times likewise says markets 'had surpassed pre-crash highs less than two years later.' Wikipedia's stock market crash article corroborates the timing, placing the Dow's full recovery at September 1989, roughly 23 months after the October 19, 1987 crash.
