Interest rates are not the tool to solve the inflation caused by the US’s war with Iran

We’ve been here before with Covid and Ukraine. Making borrowing more expensive won’t work – only price controls, caps and public ownership can do that
T
he Bank of England’s interest-rate committee
meets on Thursday
, facing up to the global inflation shock triggered by the illegal US-Israeli war on Iran. The most immediate driver of inflation is the
effective closure of the strait of Hormuz
by the Iranian military, a
global chokepoint
through which 20%-30% of the world’s oil, gas and fertiliser inputs are normally shipped from the Gulf states.
Benchmark
oil and gas prices
are up by more than 40% and 50%, respectively. The UK is highly exposed, given that we are net importers of gas and have an energy market where the global price of gas directly influences the cost of electricity provision. The energy price cap will shield most households until the summer, but UK diesel prices are already up by
about 12% and petrol by 6%
. The government has intervened with a
£53m package
to support households in rural areas that heat their homes with oil.
Meanwhile, analysts have warned that the fertiliser shortage could trigger a global
food shock worse than that of 2022
, following Russia’s full-scale invasion of Ukraine, with food production threatened on multiple continents. The UK is again highly vulnerable, having just
54% self-sufficiency in food
, compared with countries such as the US, France and Australia, which are all food self-sufficient, meaning they grow enough food to feed their populations without imports if required.
In the face of sluggish growth – the economy
flatlined in the month to January
– and gently declining inflation since last summer, the Bank has been gradually lowering interest rates from a
peak of 5.25%
in the summer of 2024
to 3.75%
. The expectation is that these cuts will now end. Financial markets have already priced in the Bank raising interest rates back up to 4% by the middle of next year, immediately reflected in rises in mortgage interest rates.
Central banks, including the Bank of England, came in for
a lot of criticism
for raising rates too slowly during the last inflation spike caused by the Covid shutdown and the Russia-Ukraine war.

But as the cost-of-living crisis threatens to worsen further for UK households, the Bank should hold its nerve and continue on the path of lowering rates. This is clearly another supply-side shock for which raising (or, in this case, not lowering) interest rates will have little impact on price pressures but further dampen growth and investment.
In fact, there is little evidence that the rapid rate hikes of 2022 made a significant difference to inflation. The clearest driver of reduced price growth was the
decline in energy and food prices
that eventually materialised in late 2022. A 2025
International Monetary Fund study
found that inflation-targeting central banks that rapidly raised interest rates in 2022 fared no better than non-inflation targeting central banks in dealing with the price rises of 2021-2022.
The unfortunate truth is that the current monetary policy framework – not only in the UK but also the US and eurozone – remains shaped by the scars of the last time a major inflation crisis emerged from a war in the Middle East: the early 1970s. Back then, the rise in energy prices set off “wage-price spirals”, as firms raised prices to maintain profits and powerful trade unions responded by pushing up wages. By ramping up interest rates to very high levels in the early 1980s, central banks, led by the US, eventually helped crush lingering inflation, but only at the cost of severe recessions and
decades long higher unemployment
.
Since then, central banks have become convinced that inflation is driven by the expectations of future price rises of both firms and households. Their key job was to “anchor” such expectations via snuffing out any sign of wage-price spirals with interest rate hikes.
Today, we are in a very different situation. Labour is much weaker due to declining trade unions and a global labour force. Meanwhile, firms in the energy and food sectors in particular have huge market power to set prices as they wish. There was virtually no evidence of “wage-price spirals” during the 2021-23 inflation period, but rather more of
“profit-price” inflation
, as firms maintained profits by ramping up prices, causing initial supply side shocks to energy and food to ripple through to general inflation.
Furthermore, surveys show th

- In fact, there is little evidence that the rapid rate hikes of 2022 made a significant difference to inflation.
- As shown by countries such as Spain , these types of measures were more effective in controlling inflation than was raising interest rates.

### Areas for Consideration
- Central banks, including the Bank of England, came in for a lot of criticism for raising rates too slowly during the last inflation spike caused by the Covid shutdown and the Russia-Ukraine war.

### Implications
