Oil price drop and stable rates: What the US-Iran deal means for your home

The preliminary peace deal between the US and Iran has sent Brent crude oil prices tumbling by roughly 30% from their mid-crisis peak, now trading around $76 per barrel as of June 18, 2026. This significant drop has helped ease inflationary pressures on the UK economy, allowing the Bank of England to hold its main interest rate at 3.75% for the fourth consecutive meeting.

What changed and by how much?

The reopening of the Strait of Hormuz, a critical oil and gas conduit, has been a key factor. Oil prices, which soared to around $118 per barrel in April during the conflict, have now stabilised, though they remain about $10 higher than before the US and Israeli attacks on Iran began in February 2026.

This decline in energy costs has directly impacted UK inflation. The Consumer Prices Index (CPI) rose by 2.8% in the 12 months to May 2026, remaining unchanged from April. This is a welcome dip from the 3.3% seen in March 2026 during the height of the conflict, and lower than the Bank of England's earlier projection of 3.3%.

On June 18, 2026, the Bank of England's Monetary Policy Committee (MPC) voted to maintain the base rate at 3.75%. Seven of the nine MPC members opted to hold rates, while two voted for a 0.25% increase. This decision signals a more 'benign' inflation outlook, according to the Bank.

Impact on Homeowners and Buyers

For homeowners, the stability in the base rate offers a glimmer of hope. Average two-year fixed mortgage rates are currently around 4.8%, with five-year fixed rates at 4.9%. Forecasters now expect two-year rates to fall to between 4% and 4.5% by the end of 2026, provided inflation remains under control.

Scenario: Homeowner with a fixed-rate mortgage expiring soon

If your two-year fixed mortgage of £200,000 at 2.5% is due to expire, you might be looking at remortgaging at around 4.8%. This could see your monthly payments jump significantly. However, the prospect of rates falling to 4-4.5% by year-end suggests that waiting, if possible, or opting for a shorter fixed term, might be worth considering. A fall from 4.8% to 4.5% on a £200,000 mortgage over 25 years could save you around £35 a month.

Average UK house prices increased by 3.8% to £270,000 in the 12 months to April 2026. This rise is partly attributed to a 'base effect' from a sharp price decrease a year ago following Stamp Duty Land Tax (SDLT) changes in April 2025. London, however, saw a decrease of 2.1% to £553,000, while North East England experienced a 9.9% rise to £163,000.

Impact on Renters

Renters continue to face upward pressure on costs. Average UK monthly private rents increased by 3.3% to £1,383 in the 12 months to May 2026, a slight slowdown from 3.5% in April. Wales saw the highest annual increase at 4.7%, while London's average rent of £2,294 increased by 2.0%, the lowest among English regions. The North East, again, saw the highest rental inflation at 5.9%.

The underlying issue remains supply, with rental homes still 20% to 30% below pre-pandemic levels across every region.

Scenario: Renter in the North East

If you're renting in the North East, where average rents are seeing the highest annual inflation at 5.9%, a £900 monthly rent could increase by over £50 a month. With supply remaining tight, finding a more affordable option can be challenging.

But there are risks

Andrew Bailey, Bank of England Governor, noted on June 18, 2026, that while the recent decline in oil prices has been 'encouraging', they are still higher than before the war. He warned, 'Whatever happens in the future, the higher energy prices of the past four months mean there's already some inflationary pressure in the pipeline. The Bank's job is to make sure that doesn't turn into sustained inflation above our 2% target.'

This suggests that while the immediate crisis has eased, the Bank remains vigilant, and further interest rate hikes are not entirely off the table if inflation proves persistent.

What this means for you

For homeowners, if your fixed-rate deal is ending soon, it may be worth exploring your options now but also keeping an eye on the market for potentially lower rates towards the end of 2026. Consider speaking to a mortgage adviser about shorter-term fixes or tracker mortgages if you're comfortable with some risk.

First-time buyers should continue to save diligently. A Lifetime ISA (LISA) offers a 25% government bonus on contributions up to £4,000 per year, meaning you could get £1,000 free from the government annually. For other savings, a Cash ISA allows you to save tax-free, while your Personal Savings Allowance means most people can earn some interest tax-free outside an ISA too.

Renters facing increases should review their budgets and, if possible, negotiate with landlords or explore alternative properties, though be aware of the tight supply in many areas. Utilise budgeting tools to track your spending and identify areas for potential savings.

Step-by-step what to do right now

1. Review your mortgage: If your fixed rate is ending within the next six to nine months, start comparing new deals. Many lenders allow you to lock in a rate in advance.
2. Boost your savings: If you're a first-time buyer, maximise your LISA contributions. For general savings, look for the best Cash ISA rates, noting if they are variable or include a temporary bonus.
3. Check your budget: With potential changes to energy costs and continued rental increases, understanding your incomings and outgoings is crucial.
4. Seek advice: Don't hesitate to consult an independent mortgage adviser for personalised guidance on your specific situation.

When effective

The immediate impact of the peace deal on oil prices was seen in mid-June 2026, with the Bank of England's decision to hold rates made on June 18, 2026. Forecasts for mortgage rates falling to 4-4.5% are for the end of 2026, so the full effect on your household budget may take time to materialise.

Where to get help
