Savers have been warned that ‘Trumpflation’ could erode the value of their rainy day fund by £275, as rising oil prices mean inflation could surpass interest rate rises.
The Bank of England published three hypothetical ‘stress test’ scenarios this week, showing where it thinks inflation and interest rates could end up depending on how the conflict plays out.
Its worst case scenario would see oil prices, currently $100 a barrel, hit $120 and stay at that level while inflation would peak at 6.2 per cent.
The Bank of England base rate usually goes up when prices go up, because it can help to bring overall inflation down. This results in savings rates being hiked, as people tend to squirrel more money away rather than spending.
However, analysis by rates scrutineer Moneyfacts suggests that if inflation grows to the ‘worst case’ scenario of 6.2 per cent, the value of people’s savings will likely be eroded faster than interest rates can keep up.
It thinks we could see top savings rates of up to 4.75 per cent – giving someone £475 interest per year on £10,000.

But compared to the 6.2 per cent rate of inflation, a £10,000 savings pot could make a real-terms loss of £145, the analysis shows.
Before the war and the resultant spike in energy costs, you would have likely gained £135, even with interest rates expected to drop.
That means savers could be £275 poorer in the worst-case scenario.
And that is only those who keep their money in higher-paying savings accounts. Those with poorer rates could be far worse off.

The Bank of England’s worst-case outcome would only occur if hostilities between the US and Iran continue and the vital waterway the Strait of Hormuz remains closed for the foreseeable future.
This would make it difficult for around 20 per cent of the world’s energy supplies to be exported – pushing up the price of oil and gas.
If, on the other hand, the trading route opens and energy prices ease more quickly your savings will not lose value – but they would not gain any either.
| Scenario | Inflation outlook | Energy/oil assumption | Base Rate implication | Est. savings rate | Annual return (£10k) | Gap vs est. inflation |
|---|---|---|---|---|---|---|
| Pre-conflict baseline | 2% trajectory | Lower, stable | 3.75% (with cuts expected) | 3.30% | £330 | £130 |
| 07-May | Rising | Oil elevated | 3.75% (no expectation of cuts) | 3.51% | £351 | Negligible |
| Scenario A (benign) | Peaks 3.6%, falls below 3% | Prices fall back | 3.75% | 3.25% | £325 | Negligible |
| Scenario B (central) | Peaks 3.7%, stays elevated | Slower energy decline | 4-4.25% | 3.50%-3.75% | £350-£375 | Negligible |
| Scenario C (worst case) | Peaks 6.2% | Oil >$120 sustained | Up to 5.25% | 4.75% | £475 | -£145 |

With inflation at a more manageable 3.7 per cent and a base rate of around 4 per cent – the Bank of England’s central or ‘medium’ scenario – will likely see returns of £351 on a £10,000 savings pot.
But with inflation, the real terms gain will be negligible. Markets currently view this as the most likely path.
Adam French, head of consumer finance at Moneyfacts, said it was important for savers to check their money was in the best possible account.
‘The Bank of England’s ‘Trumpflation’ stress scenarios show that while savers may see higher rates in the months ahead, the bigger challenge remains whether returns can keep pace with inflation.
‘For savers, remaining proactive is essential. Fixed bonds can help lock in stronger returns while regular reviews are important because many providers are slow to pass on base rate increases in full.

‘Using Isa allowances where possible can also help protect returns from tax, particularly as higher rates mean more savers risk breaching their Personal Savings Allowance.
‘However, holding excessive cash savings long-term isn’t always the best plan for building wealth. Savers with surplus funds should also consider higher-return options such as stocks and shares ISAs, although this depends on their risk-tolerance and financial plans.’
It comes as new data today revealed that the vast majority of people are dipping into their savings to pay for everyday essentials.
Some 84 per cent are using their ’emergency fund’ savings to pay for everyday essentials while nearly one in five are using it for food, comparison website MoneySuperMarket’s Household Index showed.
Kara Gammell, personal finance expert at MoneySuperMarket, said: ‘For many households, savings are no longer just a safety net. They’re also being used as a financial buffer to manage everyday spending, from food shopping to energy bills, alongside money set aside for long-term goals.
‘That’s a notable shift, reflecting how people are adapting their finances to stay on top of rising day-to-day costs.’
