How the Iran war affects your money and bills

From petrol prices to mortgage rates. the US-Israel war with Iran has already had an impact on people's finances in the UK.

Hopes of a lasting deal to end the war have risen,. the political situation can change quickly as too can the effect on personal budgets.

Here are some of the areas to watch out for.

Drivers have noticed thatprices at the pumphave jumped since the war began, but have since dipped from their peak.

Crude oil is a key ingredient in petrol. diesel, meaning higher wholesale costs make filling up a car more expensive.

Since the war began, that wholesale price has been volatile as the production. transportation of energy across the Middle East has been disrupted.

According to the RAC. the price of petrol reached an Iran war peak of 159.53p a litre on 28 May, while diesel's highest price was 191.54p a litre on 15 April.

The latest data shows petrol was marginally under 157p a litre,. diesel just under 178p, with the RAC expecting further falls.

It now costs £97.22 to fill up a 55-litre family car with diesel – £18.91 more than it did on 28 February,. £85.74 for a tank of petrol – £12.68 more than at the start of the conflict.

Transporting oil is a slow process. so price movements in the wholesale markets take about a fortnight to show at the pump.

It also means that, were the Strait of Hormuz to reopen, it will take some time for oil -. economic activity - to flow freely again.

Fuel retailers have denied accusations of price gouging during the conflict. the regulator has said there isno evidence of widespread attempts of profiteering.

Higher petrol prices can also carry through to increased prices for goods and services. For example, if transport costs for supermarkets rise that could then be reflected in the cost of food.

Before the war began, there had been a hope. expectation of asteady fall in the interest ratescharged on new, fixed mortgages, as well as lower variable rates.

However, the situation has proved to be much more volatile.

Lenders raised rates quickly, due to their own funding costs rising. an expectation that the base borrowing rate would not fall as previously anticipated.

The average two-year fixed rate jumped from 4.83% at the start of March to a peak of 5.90% on 12 April. according to the financial information service Moneyfacts. It has since dropped to 5.61% as of mid-June.

For those looking for a five-year deal, the average rate rose from 4.95% to a peak of 5.78%,. has since dipped to 5.58%.

As a result, many face higher repayments than they might otherwise had planned.

The Bank of England says that over the next three years. average monthly payments for those moving on to a new deal areexpected to rise by approximately £80. That is an average and there could be considerable variation.

About 53% of UK mortgage holders are expected to see their payments rise, the Bank says,. around 25% of those who fixed at higher rates should see their payments fall, despite recent increases in rates.

There is some protection in place for household gas. electricity bills, thanks to the price cap in England, Wales and Scotland set by energy regulator Ofgem.

However, it is time limited and does not cover everyone.

The maximum price for each unit of energy, for those on variable deals governed by the cap,is set until July.

However, in July prices will rise by 13% as the higher wholesale costs, faced by suppliers, feed through to bills.

Under Ofgem's price cap for July to September, a dual-fuel household using a typical amount of gas. electricity would pay about £18 a month more for energy - driven by a considerably higher charge for gas.

The last time there was a particular spike, following Covid. Russia's invasion of Ukraine, the government had to step in to help with the Energy Price Guarantee (EPG).

The chancellor has said there could be government support if needed for bills at the start of winter but. unlike the EPG,it would be based on household incomeand targeted at those who need it most, rather than universal.

As yet, prices from October onwards are highly uncertain, although the current situation suggests they may not rise at all.

The most immediate impact of rising prices was felt by those who use heating oil. often stored in a tank outside their property. There is no cap that limits the cost.

Heating oil is used widely in rural areas and in Northern Ireland.

In March, Prime Minister Sir Keir Starmer announcedsupport amounting to £53mfor the most vulnerable users of heating oil. The money will be distributed via the devolved authorities. In England, councils will decide who qualifies and how they will receive the financial help.

Competition authorities are also checking whether heating oil customers are being treated fairly.

At the start of March,UK inflation– which charts the rising cost of living – was forecast to be at or around the Bank of England's target level of 2% over the next five years. according to the Office for Budget Responsibility (OBR).

The government's official forecaster said the price of a typical basket of goods would be going up at a rate of 2.3% this year. then 2% a year from 2027. But, it did those sums before the airstrikes on Iran began.

Instead the cost of living has risen at a faster rate.

Making an inflation estimate becomes very difficult, given the volatile situation militarily and economically.

However. analysts say there is no expectation or the rate of inflation returning to the peak of 11.1% seen in the UK in October 2022. That is because the war in Ukraine also caused spikes in the prices of basic foodstuffs, such as wheat. edible oil, owing to the role of Ukraine in producing those items. That is not the case now.

In April. the Bank of England's most adverse scenario predicted inflation would only go to just above 6% early next year.

The Bank of England is charged with getting inflation to as close as 2% as possible,. its primary tool to do so is interest rates.

After the rate-setting committee met in February. the Bank's governor Andrew Bailey said there was scope for further rate cuts this year.

However, since then, the committee has twice held the Bank rate at 3.75%. saidit is willing to act if the Iran war fuels inflation over time.

The prospect of imminent rate cuts has vanished but the chances of rises too have dwindled.

It rates do go up, it would make borrowing money more expensive, but savings could be slightly more lucrative.

In times of uncertainty, people have previously hoarded savings. The spending power of that money may reduce, if the cost of living rises,. it may hit general economic growth in the UK.
