What happened

Oil prices have jumped above $105 a barrel following attacks on shipping in the Middle East. The movement is compounded by a storm threatening US oil output in the Gulf of Mexico.

Why it mattersSuch disruptions can lead to increased energy costs globally, affecting economic growth and inflation expectations.

Market context The geopolitical risk premium in oil prices has risen sharply, with Brent crude surpassing $105 per barrel. This is further exacerbated by potential supply disruptions in the Gulf of Mexico due to an approaching storm.

Already priced in? Initial market reactions have occurred, but further geopolitical developments could alter pricing.

How it spreads

Each step below is caused by the step above it. The first effect is obvious and already reflected in prices. The ones after it usually are not.

1 The cost of money strong

Moves government bond yields, which set the baseline return every other investment is judged against. When that baseline moves, everything reprices.

  1. Oil price increases push inflation expectations higher. Rising oil prices feed into higher inflation expectations, influencing the discount rate as central banks may adjust their outlook.
  2. Higher inflation expectations lead to higher bond yields. As inflation expectations rise, bond yields increase as investors demand higher returns for inflation risk.

2 Company profits moderate

Changes revenue, costs or pricing power somewhere in a supply chain, including for companies not mentioned in the story.

  1. Higher oil prices increase costs for companies reliant on energy. Companies with high energy dependency face increased input costs, which may squeeze profit margins if they cannot pass on costs.
  2. Reduced profits lead to lower stock prices in affected sectors. Sectors like transportation and manufacturing see stock prices fall as profit margins are pressured by rising energy costs.

3 Currencies and trade moderate

Moves an exchange rate, which changes what importers pay and what exporters earn.

  1. The euro weakens against the dollar due to economic uncertainty. With rising oil prices and geopolitical risks, the euro depreciates as investors seek safety in the US dollar.
