After Meta’s 7% Drop, AI Selloff Moves Bonds, Credit, Gold

The selloff in AI stocks that hit Wall Street on 22 October 2026 had reached bonds, credit spreads and gold by the next morning, while Korean stocks recovered by the 23 October close. Reuters reported that the Nasdaq fell 2.6% on 22 October, its steepest daily drop since early June, as a batch of high-profile earnings “ignited fresh fears about the AI spending race.” The Philadelphia SE Semiconductor Index “plunged 6.7%, its biggest daily percentage drop since June 23,” according to Reuters.

On the same day, Bloomberg reported that Treasuries had “their best day in more than two years.” On 23 October it reported that corporate bond yield premiums globally reached up to 129 basis points, their widest since May 2025, on a Bloomberg index. In Asia on 23 October, the Kospi, which Bloomberg reported slid as much as 4.1% during the day, recovered its losses and closed 0.30% higher at 5,550.30, according to Korea Exchange data shown by Naver Finance; the Nikkei 225 closed 0.34% lower by our arithmetic.

Business Pill · FINANCIAL CONDITIONS

A short Business Engineer explainer on financial conditions: how easy or hard it is to borrow and raise money. It teaches the general idea only and says nothing about any company in this piece.

The Data Point: One Selloff, Market by Market

We put the moves from the past 24 hours in one table, each with the cause its source names. In most rows the source names AI stocks as a cause; in several it names others alongside, such as oil, turmoil in France or tensions in the Middle East.

Sources: Reuters (Stephen Culp and Tharuniyaa Lakshmi, 22 Oct 2026); Bloomberg (22 and 23 Oct 2026, the articles’ free openings); exchange data for the 23 Oct Asian closes as stated in each row. The Session column gives the session each figure describes. The rows mix percentage moves, yields and spreads, so they are listed side by side and never added up.

Stocks: The Chipmakers Led

Reuters reported that Meta Platforms’ results beat analyst expectations, but its stock slid 7.0% as the company posted its first cash outflow in more than a decade “due to its AI-related expenditures.” Tesla fell 3.1%. With the 22 October decline, Reuters wrote, the semiconductor index “is off more than 26% from its record closing high reached on June 22.”

In Seoul, Samsung Electronics and SK hynix “each dropped more than 4% at one point,” Bloomberg reported, before SK hynix recovered. By the close, Korea Exchange data shown by Naver Finance put SK hynix 4.42% higher at 1,277,000 won and Samsung Electronics 0.47% higher at 215,500 won. In Tokyo, the Nikkei 225, which Bloomberg reported fell as much as 2.3%, closed at 62,693.16, down 0.34% from the previous close by our arithmetic, using Yahoo Finance data. Tokyo Electron closed at 9,458 yen and Advantest at 32,340 yen, both within 0.1% of their previous closes by our arithmetic.

Bonds: The Move Into Government Debt

A bond’s yield moves opposite to its price, so falling yields mean investors are buying. On 22 October, a deepening rout in AI-related shares, market turmoil in France and fresh Mideast tensions “all combined to make US government debt the investment of choice for anxious traders,” Bloomberg reported. The 10-year benchmark recorded its biggest one-day drop since August 2024, according to the report.

The move spread to Japan on 23 October. Japanese government bond yields “fell across the curve on Friday as an AI-driven selloff in equities boosted demand for haven assets,” Bloomberg reported, with the 10-year yield down as much as 10 basis points to 2.78%.

Credit: Lenders Asked for More

A credit spread is the extra yield a company pays over a government to borrow; it widens when lenders want more for the risk. “Metrics across global bond markets are signaling their biggest risk-off sentiment in more than a year, as a selloff in AI stocks and growing geopolitical tensions caused investors to seek out safe-haven assets,” Bloomberg reported on 23 October. Spreads on dollar bonds of higher-rated Asian companies widened to their highest levels since last July, according to the report.

Gold Fell Too

Gold did not rise with bonds. Bullion dropped as much as 0.9% to less than $3,990 an ounce on 23 October, the lowest since mid-July, after falling almost 3% on 22 October, Bloomberg reported. In a post on X, Bloomberg wrote that “investors sold the precious metal in a cross-market stock rout.” The same article said stock selloffs deepened on 23 October while Treasuries largely held their gains, “as investors rotated out of artificial intelligence-related companies and sought safety in US bonds.”

Chinese AI Model Stocks

The combined market value of MiniMax Group and Z.AI, also known as Zhipu, was down $150 billion from their respective highs as of the 22 October close, Bloomberg reported, calling it “a brutal reversal after the duo’s hotly anticipated market debuts in January.”

Connecting the Coverage

Our AI-doubts piece reported on 22 October 2026 that Chinese stocks had entered a bear market, with US$2.4 trillion lost since a peak in May, according to Bloomberg. Our CSI 300 piece, the same morning, reported Bloomberg’s account that the index had fallen 20% from a high in June and that US Treasuries rose as investors sought shelter. Our Kospi piece reported that the Kospi fell 3.73% to 5,552.74 on 20 October, according to Yonhap.

What’s new: the 22 October US close, the bond, credit and gold moves, and the 23 October Asian close, where the Kospi recovered.

Our insurers piece reported on 23 October that, according to CNBC’s 22 October analysis of FactSet data, five-year credit default swap spreads had widened for CoreWeave, Oracle and SoftBank Group, and its 23 October Update carries the Bloomberg spread figure used here. Our Solidigm piece reported that SK hynix halted the review of a potential US listing of the unit on 23 October; the filing names market conditions, and Bloomberg reported strong opposition from regulators and shareholders, calling SK Hynix the latest firm to pull an IPO while markets “gyrate on doubts about the AI boom.”

The Structural Read

As we read it, the bond moves are the clearest sign of how far the selloff reached: Bloomberg tied US Treasuries’ best day in more than two years to the AI rout alongside turmoil in France and Mideast tensions, and Japanese yields fell on an AI-driven selloff in equities.

As we read it, the credit move matters for the companies financing the build-out with debt, because global corporate bond spreads widened to up to 129 basis points on a Bloomberg index, the widest since May 2025.

As we read it, gold did not behave as a haven this time: Bloomberg reported it fell to its lowest since mid-July while Treasuries held their gains.

Three Implications

FOR AI BORROWERS Bloomberg reported corporate bond yield premiums globally reached up to 129 basis points, the widest since May 2025, which by the definition above means lenders asked for more extra yield.

FOR CHIPMAKERS Reuters reported the semiconductor index is off more than 26% from its record close of 22 June; in Seoul, SK hynix closed 4.42% higher on 23 October after falling more than 4% at one point, according to Bloomberg and Korea Exchange data.

FOR READERS TRACKING THE CAUSE The sources name AI alongside oil, turmoil in France and Mideast tensions, and none of them splits a move between its causes.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Capex Map.

The framework’s thesis: “the capex race is no longer a corporate spending cycle. It is a sovereign-scale financing problem dressed in tech-company clothing”.

As we read it, the 22 and 23 October moves show that financing problem being priced outside the spenders, in government bonds and corporate credit spreads. The framework was published in May 2026 and does not discuss these moves.

What Is Not Established

The sources name AI alongside other causes for several of these moves, including oil prices, turmoil in France and tensions in the Middle East, and none of them splits a move between its causes. The US figures are from the 22 October session and the Asian ones from 23 October, so the rows are not a single day. Bloomberg’s figures come from the free opening of each article; we did not read the full texts. Nothing here is investment advice.

The Bottom Line

By the sources’ own accounts, the 22 October selloff in AI stocks reached US Treasuries, Japanese bonds, global credit spreads and gold within a day. In Asia, the Kospi and the big Korean chipmakers closed higher on 23 October after falling during the session, and the Nikkei 225 closed 0.34% lower by our arithmetic. Global corporate bond spreads stood at up to 129 basis points on a Bloomberg index, the widest since May 2025.
