Brent Crosses $100 and Equities Slide for a Third Day

Brent crude crossed $100 a barrel for the first time since July, and held near that level as the session went on.^1,2 Wall Street futures had already dipped before the open on the back of the move.² The Guardian tied the rise to escalation in the Iran war.⁶ Barron’s described the same session as a return of Iran war fears, with stocks struggling as Brent topped $100.⁴

US equity indexes fell for a third consecutive day, with the Dow down 300 points and the S&P 500 and Nasdaq also lower as Brent reached the $100 mark.⁵ Earlier in the shortened week, CNBC reported the Dow dropping 600 points as oil prices climbed.³ Bank of England governor Andrew Bailey said the latest rise in oil prices was putting pressure on inflation and interest rates.⁶

Why it matters to investors

Morgan Stanley analysts led by chief US equity strategist Mike Wilson wrote that “higher oil and rates remain the main risks to equities in the near term.”^1,2 Wilson said separately that he still considers this a bull market, while naming higher oil prices and interest rates as the risk to it.⁷ He also said momentum is ripe for a comeback.³ That is a strategist holding a constructive view while conceding that the two variables moving against him are the ones now in the headlines.^1,7

The read is not unanimous. David Rosenberg of Rosenberg Research described the recent moves as a market rotation without direction, rather than a directional break.⁴ UBS took the milder view that higher crude prices are unlikely to prompt aggressive tightening, calling the level a milestone rather than a turning point.⁸

What to watch

The oil move lands immediately ahead of US consumer price data and a European Central Bank decision, both of which UBS flagged as the events that follow the crude milestone.⁸ MarketWatch noted that Treasury Secretary Scott Bessent’s plan to buy more long-dated US government bonds has ignited a fight over the direction of the Treasury yield curve.⁵ Equities are therefore taking a signal from the oil price and from the long end of the curve at the same time.^1,5

Bailey set out the transmission chain plainly: oil pressing on inflation, and inflation pressing on rates.⁶ That is the same pair of variables Morgan Stanley put at the top of its risk list, which means the next inflation print and the ECB decision speak to both at once.^1,8 Whether Brent holds triple digits, rather than merely touching them, is what determines how much of that feeds through.^2,8
