Shaybah attack lifts Brent as Meta’s spending plans hit the Nasdaq.

A drone attack near Saudi Arabia’s Shaybah oilfield took Brent to a five-month high, and Meta’s spending guidance hit tech. Bitcoin and gold also fell; the evidence for those two links is weaker.

By the Causa DeskPublished

What moved markets on Thursday 22 October 2026, and why?

Brent rose about 2.7% to near $111.80 after Saudi air defences shot down a drone aimed at a processing plant at Shaybah; falling debris killed two contract workers. The Energy Ministry said output was unaffected.123

In New York, Meta fell more than 6% despite beating forecasts, as investors focused on its higher spending plans for AI. The Nasdaq Composite was down about 2.2% by late morning.45

Bitcoin and gold also fell. The link from oil to bitcoin is well reported; the gold move is harder to explain and is graded accordingly. Each file states the condition that would invalidate it, with a deadline, and the Scorecard tests it against closing prices.67

Brent crude +2.7% to $111.77

Brent prices Saudi supply risk after the Shaybah drone attack

Brent rose to a five-month high after a drone aimed at Saudi Aramco’s Shaybah field was intercepted and its debris killed two workers. No output was lost. The move is a risk premium on the chance that a future strike stops production.

  1. What happened
    Houthi drone targets a Shaybah processing plant
    Wednesday. Intercepted. Two contract workers killed by debris.
  2. Then
    Saudi energy sites look exposed
    Houthis also claimed strikes on Yanbu and on Riyadh and Abha airports. Dammam airport was hit.
  3. Then
    Risk premium widens on Brent
    Export routes are already strained by the Iran war.
  4. What moved
    Brent +2.7% to $111.77
    Highest close in about five months.

Nasdaq Composite −2.2% to 26,108

Meta falls 6% on higher spending guidance despite a beat

Meta beat on revenue and earnings but fell more than 6% after raising the low end of its capital spending range and guiding to much higher investment in 2027. With chips weak and oil rising, the Nasdaq more than reversed Wednesday’s gain.

  1. What happened
    Meta beats, then raises its spending floor
    Revenue $64.6bn against $63.4bn expected. Bigger investment ahead in 2027.
  2. Then
    Investors question the return on AI spending
    A new non-voting share class hints at future funding needs.
  3. Then
    Mega-caps and chip stocks sell off
    Lam Research also fell after earnings. Tesla swung after cutting capex.
  4. What moved
    Nasdaq −2.2%
    Reverses Wednesday's 1.05% gain.

Bitcoin −3.4% to $81,618

Bitcoin reverses from a two-week high as Brent tops $111

Bitcoin opened at its highest level since 7 October and fell more than 3% as Brent rose above $111. The reported channel runs from oil to inflation expectations to Fed pricing, which weighs on risk assets.

  1. What happened
    Brent pushes above $111
    Five-month high after the Shaybah attack.
  2. Then
    Inflation worries return
    A December Fed hike is already priced at about 80%.
  3. Then
    Risk assets lose appeal
    Bitcoin trades with tech on a falling Nasdaq.
  4. What moved
    Bitcoin −3.4%
    From an $84,024 open to about $81,600.

Gold −1.9% to $4,062

Gold falls 1.9% in a risk-off session

Gold fell despite a risk-off session that would normally support it. Our best explanation is the rate path: gold pays no yield while the Fed is still raising. The evidence is weak, and the file is graded C.

  1. What happened
    Fed still in hiking mode
    September hike. December hike priced.
  2. Then
    Oil adds to inflation fear
    More hikes stay on the table.
  3. Then
    Yield-free gold loses ground
    The 10-year has held above 5% for weeks. The dollar is firm near 101.6.
  4. What moved
    Gold −1.9%
    To $4,062 at 10:54 New York.

US 10-year yield −8 bp to 5.07%

Treasuries catch a bid while oil climbs

Higher oil usually lifts yields through inflation expectations. On Thursday, haven demand from the equity selloff dominated and Treasuries rallied. The Fed meets next week and is expected to hold.

  1. What happened
    Tech stocks sell off
    Nasdaq −2.2% after Meta and Tesla.
  2. Then
    Money moves into Treasuries
    Haven demand outweighs the inflation signal from oil.
  3. Then
    Fed seen on hold next week
    Hike odds for 28 October are low. December is the live meeting.
  4. What moved
    10-year −8 bp
    About 5.07%, near one-month lows.

What we are watching

27 and 28 OctoberFederal Reserve meeting

Markets expect a hold, with a hike priced for 9 December. Any hint of an earlier move would hit bitcoin, gold and tech together.89

This weekHouthi strikes on Saudi Arabia

Attacks have spread from energy sites to airports, and the US is preparing to move some embassy staff out of the Gulf. A strike that stops output would turn a premium into a shortage.110

Rest of OctoberMore big tech earnings

Meta fell on spending guidance despite a strong quarter. The next reports show whether the market applies the same test across the sector.5
