What happened

Crude oil futures ended the week lower as the market expects the US to tighten sanctions on Iran, leading to negotiations rather than military actions. This expectation is based on the belief that increased Iranian oil supply will enter the market.

Why it mattersThe decline in oil prices affects energy companies' profits and can influence inflation expectations, which in turn may impact monetary policy decisions.

Market context The market is adjusting to the possibility of increased Iranian oil supply as US sanctions may lead to diplomatic talks. This has led to a revaluation of oil futures prices, anticipating a more stable geopolitical environment.

Already priced in? The market had expected some impact from increased Iranian supply, but the scale of potential negotiations was not fully absorbed.

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 Company profits strong

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

  1. Lower oil prices reduce revenue for oil companies. A drop in crude prices compresses margins for oil producers, impacting their earnings outlook.
  2. Reduced earnings pressure oil company stock prices. As earnings expectations decline, investors may sell off shares in oil firms, leading to a decrease in stock prices.

2 What central banks do next moderate

Changes how likely it is that central banks cut or raise interest rates, and how quickly.

  1. Lower oil prices could ease inflation pressures. With reduced energy costs, headline inflation may moderate, affecting central bank inflation targets.
  2. Central banks may delay interest rate hikes. If inflation pressures ease, central banks might adopt a more dovish stance, postponing rate increases.

What the market may be missing

Investors may underestimate the potential for prolonged negotiations with Iran to stabilise oil supply, which could lead to a more sustained period of lower prices than currently expected.

The market might not fully appreciate the impact of extended diplomatic talks with Iran, which could keep oil prices subdued for a longer timeframe, affecting long-term inflation expectations and monetary policy.
