Global markets experienced significant turmoil on October 22, 2026, as the Nasdaq 100 fell by nearly 3% and Brent crude oil prices surged to $112-$113 a barrel, influenced by a US tech rout and escalating geopolitical tensions in the Middle East [3][5][7][11].

This convergence of events signals a period of heightened economic uncertainty, impacting both the technology sector's investment strategies and the stability of global energy supplies. Investors are reassessing the sustainability of AI-driven growth and grappling with the immediate threats to oil production and shipping routes.

## What the records show

The Nasdaq 100, a tech-heavy index, dropped nearly 3% on October 22, marking its worst day since June [11]. This downturn followed earnings reports from major tech companies Meta Platforms and Tesla, which fueled investor concerns about the financial returns of massive artificial intelligence (AI) investments [3][11].

Meta Platforms reported a negative free cash flow of $2.12 billion in the third quarter of 2026, the first such instance since its 2012 initial public offering [1]. This was driven by $34.91 billion in capital expenditures, primarily for AI infrastructure, which outpaced $32.79 billion in operating cash [1]. Meta shares fell more than 7% as investors reacted to an increased AI spending forecast [2]. Tesla, while reporting an unexpected $1.5 billion in free cash flow, cut its full-year capital expenditure guidance to $20 billion from over $25 billion [4][22][23]. This reduction sparked concerns among investors regarding the pace of its AI and robotics projects [4][21].

Concurrently, Brent crude oil prices climbed to a five-month high, reaching $112-$113 a barrel [5][7][11][17]. This rise was triggered by escalating geopolitical tensions in the Middle East [5][8]. Houthi attacks targeted Saudi Arabia, including a strike on King Fahd International Airport in Dammam that killed two people and injured eight [7][18][19]. A drone attack on Saudi Aramco's Shaybah oilfield also resulted in two deaths [6][7][9].

Further disruptions emerged in the Strait of Hormuz, where Iran reported that seven oil tankers were attacked or damaged by naval mines [14][15][16]. Four of these tankers reportedly caught fire, and three others sustained damage [14][15]. These incidents, which Iran's state television attributed to the Revolutionary Guard's navy, have not been independently verified [14].

## What changed and for whom

The dual pressures from tech spending anxiety and Middle East instability led to a global “risk off” sentiment in markets [27][28]. Investors moved away from riskier assets, with some seeking safety in currencies like the yen [26].

In response to the growing threat from Houthi attacks, the US State Department ordered the evacuation of non-emergency diplomats and their families from Saudi Arabia [9][12][13]. Saudi Aramco staff also evacuated their Dhahran headquarters, marking the first such request since the start of the Iran war [9][10][19].

## What we could not confirm

PrimaryBrief could not independently verify the specifics of the claimed attacks on seven oil tankers in the Strait of Hormuz by Iran's Revolutionary Guard's navy [14].
