Middle East crisis: How oil price outcomes will impact wider financial markets

Oil prices have climbed in recent weeks to around $80 per barrel, having fallen to around $70 per barrel in early September. The recent rise suggests investors may be growing warier of the impact the conflict could have on oil supply.

Schroders' Malcolm Melville, fund manager; energy, and David Rees, senior emerging markets economist, comment on how they think the evolving conflict could impact oil prices and the wider economy:

Melville says: "The first point to make about oil is that supply and demand dynamics are currently fairly balanced for 2025, excluding Opec's proposal.

"Lower interest rates in developed markets and recent stimulus in China may generate increased demand but the demand growth is forecast to be absorbed by small increases in production from various producers.

"However, Opec has significant spare capacity after cutting supply in recent years to stabilise prices in the face of soft demand. These supply cuts have led to Opec losing market share, notably to the US, and it is planning to return extra supply from December this year.

"Spare capacity from Opec is currently very high at around five million to six million barrels of oil per day and that’s in the context of global oil demand of 102 million barrels of oil a day. That could imply a significant surplus of oil starting to emerge."

"A concern for investors is the risk that Israel may target Iran’s Kharg oil facility in the Persian Gulf. The majority of the 1.7 million barrels per day which are exported by Iran comes from the Kharg oil terminal. It is one of the largest oil terminals in the world and was targeted and damaged by Iraq during the Iran-Iraq war in the 1980s.

"The Kharg oil terminal is a real pinch point if Israel wanted to impact Iran’s ability to export oil. And they may argue that now is the time to do so, given Opec's spare capacity which could offset the loss of Iranian oil.

"However, if Israel were to weaponise oil by taking out the Kharg oil terminal, that opens the possibility that Iran could retaliate and do something such as disrupting the Straits of Hormuz."

Strategic oil vulnerability

"Situated off the coast of Iran, the waters in the Straits are very shallow, with narrow shipping lanes of two miles wide in each direction. Around 20% of all oil flows through this strategic bottleneck.

"If Israel attacks Iran’s oil facilities on Kharg Island, the global oil price could jump to somewhere in the region of $85-$90 per barrel, which is manageable for markets and where the oil price was in April of this year.

"But as soon as Iran hints that they are going to do something in the Straits of Hormuz, oil prices could spike sharply higher. I don’t think it’s unrealistic to suggest that the oil price could go back to its all-time high of $147 per barrel as the market would potentially be losing 20% of its supply.

"People may question why Iran would want to close the Straits of Hormuz as it would affect its own ability to export. However, if their oil terminal has been taken offline due to military attacks by Israel, then they won’t be exporting oil anyway.

"And they don’t necessarily need to close the whole of the Straits but could launch attacks on oil tankers, delay flows and generally cast doubt on the feasibility of exporting oil via this route.

"In conclusion, there is significant Opec spare capacity, but then there is the growing risk of a severe disruption to supply. And it's going to be a balancing act between those two forces which is going to drive the direction of oil prices."

David Rees, Schroders' senior emerging market economist, adds "It’s not our base case, but we have been modelling a “Middle East war” economic scenario for a year now. It’s a low probability, high-impact scenario. When we first modelled it, we assumed it would shave a little bit off global growth.

"The main way that scenario plays out in the rest of the world is through the oil price, which would push up inflation compared to our baseline. And that scenario would see oil prices climbing well over $100 to somewhere like $150 a barrel. But so far, oil prices have struggled to crack the $80 a barrel level.

"We would need to see oil prices climb above $100 a barrel and stay there for a prolonged period of time for there to be any meaningful change in the inflation outlook or to put any pressure on central banks to change their current interest-rate policy."
