Brent crude pushed above $100 a barrel this week as tensions between the US and Iran escalated, and fresh US tariffs landed on more than 60 countries. Both moves have revived a familiar question for UK investors: what actually protects a portfolio when inflation risk rises.
Gold is the asset most often mentioned in that conversation. This article explains what a gold inflation hedge means in practice, what the evidence says, and what other options UK investors weigh. It is for information purposes only and is not personalised financial advice.
Oil above $100 a barrel matters because energy costs feed directly into inflation figures. London stocks were set to fall at the open on Friday 24 July 2026, as Brent crude breached that level and the US introduced fresh tariffs on more than 60 countries, according to Sharecast reporting carried by Fidelity.
The FTSE 100 was separately forecast to open around 21 points lower on the same day, weighed down by the same combination of oil prices and geopolitical tension, according to coverage from the Sunday Guardian Live.
Trading Economics reported on 24 July 2026 that gold pulled back from two week highs as escalating Middle East tensions lifted oil prices and fuelled expectations that the US Federal Reserve could raise interest rates later in the year. The same report noted Iran backed Houthi forces said they had targeted two Saudi oil tankers, raising concerns about a new chokepoint for global oil supply. Higher oil prices and a higher interest rate outlook are two separate pressures, but both can weigh on portfolios at the same time.

An inflation hedge is an asset that some investors expect to hold or increase its value in real terms when the general cost of living rises. In practice, no asset offers a guaranteed hedge. Whether a hedge works depends on the period examined, the country, and the specific inflation measure used. This is a genuinely contested area of finance research, not a settled fact.
Gold is the asset most commonly associated with inflation protection, and the evidence is mixed rather than one sided. A 2017 study published in Resources Policy found evidence that gold and the UK Retail Price Index moved together over long periods dating back centuries, concluding that gold offered some protection against inflation over the very long run.
Other research reaches a different conclusion. Erb and Harvey (2013) tested the inflation hedge claim directly and found gold unreliable as a hedge across time horizons from one to 20 years, according to analysis published by the Evidence Investor in April 2026, which draws on the 2026 UBS Global Investment Returns Yearbook.
Separate research by Bampinas and Panagiotidis, published via ScienceDirect in November 2024, found gold's inflation hedging ability was generally weaker in the UK than in the US.
Historical UK data compiled by BullionVault shows gold lost close to four fifths of its real value between 1980 and 1999, a period when UK equities continued gaining in real terms despite average inflation of around 4% a year. That data draws on the Office for National Statistics long run Retail Price Index series and Bank of England interest rate records.
Gold is not the only asset UK investors weigh when inflation risk rises. Some consider a broader spread across equities, exchange traded funds (ETFs), which are index tracking funds bought and sold like shares, or shares in companies with direct exposure to energy markets.
Diversification across asset types, rather than concentrating in a single perceived hedge, is a principle widely referenced in portfolio construction literature.

| UK equities (FTSE All Share) | Continued gaining in real terms despite ~4% average inflation | BullionVault, ONS RPI series |
| Cash savings | Real value can erode when inflation exceeds interest earned | BullionVault, Bank of England rates |

This article does not recommend buying or selling any specific asset. Some investors use gold as part of a diversified portfolio when they are concerned about inflation, while others place more weight on equities, cash, or a mix of assets, including inside a Stocks and Shares Individual Savings Account (ISA), a tax efficient wrapper for UK investors.
What suits one investor will not suit another, and decisions depend on individual circumstances, risk tolerance, and time horizon. Independent financial advice can help with decisions specific to an individual's situation.
Gold is priced in US dollars, so its value in pounds also moves with the GBP/USD exchange rate, not just with global gold demand.
Gold prices are volatile and can fall as well as rise, including during periods of high inflation, as the 1980 to 1999 UK data above illustrates. Equities carry capital loss risk and can be affected by factors unrelated to inflation, including company specific news and broader market sentiment.
Currency risk applies to any dollar denominated asset held by a UK investor, since gold is priced in US dollars. No single asset removes these risks entirely.
Is gold still a good inflation hedge in 2026?
The evidence is mixed. Some studies find gold has tracked UK inflation over very long periods, while other research, including Erb and Harvey (2013), found gold an unreliable hedge across most shorter time horizons. There is no consensus answer.
What other assets are considered inflation hedges?
Equities, index tracking funds, and shares in companies with direct commodity exposure are among the assets some investors consider alongside gold. None offers a guaranteed hedge.
How does the oil price affect the stock market?
Higher oil prices can raise costs for businesses and consumers, which can feed into inflation figures and interest rate expectations. This can weigh on broader equity market sentiment, though the effect varies by sector and company.
Can UK investors hold gold inside a Stocks and Shares ISA?
Gold exposure through certain funds and ETFs can be held inside a Stocks and Shares ISA. Tax treatment depends on individual circumstances and may be subject to change. Seek independent advice.
