Oil plunges as markets price lower war and inflation risks

Brent fell nearly 9% overnight to $94.21 a barrel and is down about 20% this week. Lower energy risk lifted the S&P 500 by 1.6%, pushed the US 10-year yield down to 4.85%, and weakened the dollar.

Why it matters: A lasting oil-price decline could quickly lower inflation expectations and interest rates, but it also signals that markets are pricing a changed geopolitical risk outlook.

Political pushback against AI data centres hits chip markets

Election results in Texas and Georgia are being read as evidence of growing opposition to rapid data-centre expansion and a risk of tighter regulation. South Korea’s KOSPI fell nearly 6% and Taiwan more than 3%, while Japanese technology shares also weakened.

Why it matters: The AI rally depends on enormous spending on power and data centres; political bottlenecks can reset earnings forecasts and valuations across the semiconductor chain.

Riksbank raises its policy rate to 2%

Sweden’s Riksbank raised its policy rate by 25 basis points to 2% and said more increases may be needed over the coming year. It cited energy disruptions, a weaker krona and the risk of persistent inflation as the economy improves.

Why it matters: The decision affects the krona, Swedish bank and property shares, and household mortgage costs; the new rate applies from 11 November.

Eurozone inflation reaches 4% as an ECB hike looms

Eurozone inflation accelerated to 4.0% in October, its highest level in three years, from 3.8% in September. Core inflation held at 2.5%, but higher energy, food and services prices are reinforcing expectations of a December rate increase.

Why it matters: Higher European rates pressure valuations and financing conditions in Sweden too, and may offset some of the relief delivered by the latest oil-price fall.

The AI boom needs trillions – financing risk is rising

S&P expects six major cloud companies to spend more than $7 trillion on AI infrastructure in 2025–2030, while cash flow is projected to remain negative at least through next year. Financial executives warn that expensive capital and aggressive revenue assumptions could trigger larger market swings.

Why it matters: The next phase of the AI trade is as much about balance sheets and financing terms as model performance; tighter credit could hit the entire technology sector.
