London’s stock market is expected to open slightly lower on Thursday as oil prices surged above $100 (around £78) a barrel after new attacks on shipping in the Gulf raised fears of global supply disruption.
Market data from IG suggests the FTSE 100 could open around 8.9 points lower at 10,344.67, after the blue-chip index closed 0.6% down at 10,353.77 on Wednesday.
The drop reflects growing investor caution as geopolitical tensions in the Middle East push energy prices higher.
The situation matters for the UK because rising oil prices can quickly feed through to petrol costs, inflation levels, and household expenses, potentially affecting consumers and businesses across the country.
Why Is the FTSE 100 Expected to Open Lower Today?
The expected fall in the FTSE 100 is largely linked to rising oil prices and renewed geopolitical uncertainty.
Oil markets moved sharply overnight after explosions were reported on two foreign ships in the Gulf, raising fears that shipping routes through the region could face disruption.
At the same time, investors remain cautious about the global economic outlook, including persistent inflation pressures and geopolitical risks.
When uncertainty increases, traders often reduce risk exposure, which can lead to short-term declines in stock markets such as London’s benchmark index.
What Is Driving Oil Prices Above $100 (£78) a Barrel?
Oil prices jumped overnight following reports of explosions on two foreign ships in the Gulf, intensifying concerns about supply disruptions.
Brent crude, the international benchmark used to price UK oil imports, climbed to $100.58 per barrel (about £78.50) early Thursday, up from $91.93 (around £72) late Wednesday.
The increase has come despite efforts by governments to stabilise markets. The International Energy Agency (IEA) announced plans to release 400 million barrels of oil from emergency reserves, equivalent to roughly four days of global consumption.
However, traders remain nervous about further attacks on shipping in the region. Iran has warned oil prices could potentially reach $200 per barrel, roughly £156, if tensions escalate further.
How Do Middle East Tensions Affect Global Oil Markets?
Geopolitical tensions in the Middle East can have an immediate impact on oil prices because the region produces a large share of global energy supply.
If conflict threatens oil infrastructure or shipping routes, traders often anticipate reduced supply. That expectation alone can push prices higher.
Warnings from Iran that oil could reach around £156 per barrel have heightened market concerns about the potential scale of disruption.
Such warnings increase uncertainty in financial markets and can trigger sharp price movements.
Why Does the Strait of Hormuz Matter for Energy Supply?
The Strait of Hormuz is one of the most important maritime routes for global energy trade. Around 20% of the world’s oil supply passes through the narrow waterway each day, connecting Gulf oil producers to international markets.
If shipping in the Strait becomes unsafe or restricted, global supply could tighten rapidly.
For the UK, this could lead to:
- Higher petrol and diesel prices
- Increased transport and logistics costs
- Rising energy bills for households
- Greater inflation pressure on the wider economy
How Could Rising Oil Prices Impact the UK Economy?
Higher oil prices can quickly ripple through the UK economy. Energy costs affect sectors including transport, aviation, manufacturing, and retail logistics.
When oil prices rise, companies often face higher operating costs that may eventually be passed on to consumers.
Historically, energy price spikes have also contributed to inflation increases, something closely monitored by the Bank of England when setting interest rates.
For investors, the effect can be mixed. Energy companies listed on the FTSE 100, such as major oil producers, may benefit from higher crude prices, while fuel-dependent industries could face margin pressure.
What Are Global Stock Markets Doing in Response?
Asian stock markets moved lower on Thursday as investors reacted to rising geopolitical risk and higher energy costs.
- Nikkei 225 (Japan): down 1.3%
- Hang Seng (Hong Kong): down 0.9%
- Shanghai Composite: down 0.2%
- S&P/ASX 200 (Australia): down 1.3%
In the United States, markets closed mixed on Wednesday:
- Dow Jones Industrial Average: down 0.6%
- S&P 500: down 0.1%
- Nasdaq Composite: up 0.1%
Investors are also monitoring inflation after US consumer prices rose 2.4% year-on-year in February, according to the US Bureau of Labor Statistics.
What Do the Latest UK Housing Market Figures Show?
Separate data suggests the UK housing market continues to face pressure. The Royal Institution of Chartered Surveyors (RICS) said its latest survey showed a net balance of minus 12% for house prices in February, compared with minus 10% in January.
The figure measures the difference between surveyors reporting rising prices and those seeing declines.
Economists had expected a reading closer to minus 9%, suggesting housing demand remains weak amid higher borrowing costs.
How Are Currency and Commodity Markets Moving?
Currency markets showed modest movement early Thursday.
- Pound sterling: $1.3378
- Euro: $1.1550
- US dollar: ¥158.96
Meanwhile, gold traded at $5,160.50 per ounce, equivalent to roughly £4,020, slightly lower than the previous day.
Gold is often considered a safe-haven asset, meaning investors tend to buy it during periods of geopolitical uncertainty.
What Corporate Updates Are Investors Watching in London?
Thursday’s corporate calendar features several company updates in London. Technology services firm Computacenter is set to report full-year results, while safety technology company Halma will issue a trading update.
Investment firm M&G, events company Informa, and property adviser Savills are also scheduled to publish results.
Separately, John Lewis Partnership announced staff will receive their first annual bonus in four years.
The retailer said employees will receive a 2% bonus after profits before tax, bonus, and exceptional items rose 6% to £134 million for the year ending 31 January.
What Could Happen Next for the FTSE 100?
Investors will closely watch developments in the Middle East and the oil market.
Key factors include:
- Any further attacks on oil tankers
- The effectiveness of emergency oil reserve releases
- Upcoming economic and inflation data
If oil prices remain above $100 (around £78) per barrel, analysts say global markets, including the FTSE 100, could face continued volatility.
