What happened

Diesel prices in the UK have reached a record high of 199.18p per litre. This increase is largely due to the ongoing conflict in the Middle East, which has disrupted oil supply chains.

Why it mattersHigher diesel prices increase transportation costs, affecting consumer prices and potentially slowing economic growth.

Market context The conflict in Iran has led to supply disruptions, pushing diesel prices to record levels, reminiscent of the 2022 price spike after Russia's invasion of Ukraine.

Already priced in? The market had anticipated some impact from the Middle East conflict, but the extent of the price rise was unexpected.

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. Higher diesel prices increase costs for transportation companies. Rising diesel costs squeeze margins for logistics and transportation firms, impacting profitability.
  2. Increased costs may lead to higher prices for goods. Transport firms pass on higher fuel costs to consumers, driving inflation in goods 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. Rising inflation pressures the Bank of England to reconsider interest rates. Persistent inflation from higher fuel costs may prompt the BoE to maintain or raise rates to curb inflation.

What the market may be missing

Investors may underestimate the long-term impact of sustained high fuel prices on consumer behaviour and economic growth. If prices remain elevated, consumers might cut back on spending, leading to slower economic growth.

The market may not fully price in the potential for prolonged high fuel costs to dampen consumer spending and slow GDP growth.

How it loses money: The main risk is a resolution to the Middle East conflict that restores oil supply and lowers prices.

What would prove this wrong

  • A rapid resolution to the Middle East conflict that restores oil supply.
  • A significant drop in global oil demand that counteracts supply disruptions.
What to watch next
  • Updates on the Middle East conflict and its impact on oil supply.
  • Bank of England's next monetary policy meeting.
