Between 2022 and 2026, UK-linked billionaires whose wealth derives from energy saw their fortunes swell by 20% — four times the Rich List average. Food-production dynasties managed 15%, or three times the average. These are not abstract portfolio gains. In every case examined, wealth increases tracked increased profit margins at the businesses these families own. The mechanism is direct: crisis-driven price spikes flowed through to margins, and margins flowed through to net worth. The Perrodo family tops the list, adding roughly £3bn in four years atop their Perenco oil and gas empire. François Perrodo races at Le Mans and pitches multibillion-dollar oil investment plans to the DRC president. Perenco specialises in extracting the last drops from ageing wells — a business model that becomes spectacularly profitable when commodity prices spike. The company has simultaneously faced scandals: suing Peru's government to block an Indigenous reserve, a £6m fine for a Dorset oil spill, and accusations of failing to plug old North Sea wells. In food, Ranjit Singh Boparan — the "chicken king" who was forced out of his own company in 2018 after a food safety scandal — has tripled his family's wealth to over £2bn since 2022. His companies reportedly produce a third of all poultry eaten in the UK. The Warburton bread dynasty added £185m as bread prices climbed. Iceland founder Malcolm Walker's fortune grew by £106m. These are not tech entrepreneurs building new value; they are incumbents capturing price increases in essential goods. The numbers on the other side of the ledger are stark. UK food prices rose 38.6% between November 2020 and November 2025. Gas prices in August 2026 remained 31% above January 2020 levels. Electricity was 17% higher. Petrol roughly doubled. These are not luxury goods — they are the non-discretionary backbone of household budgets, and the people least able to absorb price shocks absorbed the most. The research, conducted by Ben Tippet at King's College London and commissioned by War on Want, compiled a sub-list of 15 Rich List families whose fortunes derive primarily from energy or food. The methodology is straightforward: cross-reference Rich List wealth movements with profit-margin trends at the underlying businesses. The correlation is tight. War on Want is using the findings to push for a £10m wealth cap, an annual wealth tax on assets above that threshold, and international coordination through the emerging UN Tax Convention. The political timing is pointed. Labour members are meeting in Liverpool with cost of living as a stated priority for Andy Burnham's government. War on Want's argument is that addressing living costs without addressing wealth concentration is treating symptoms while feeding the disease. Whether or not you buy the specific policy prescriptions — a £10m cap is radical by any standard — the underlying data pattern is clear: the same crises that squeezed household budgets turbocharged the fortunes of those who own the supply chains for essentials. The structural question is whether this is a temporary windfall that will normalise or a ratchet. Energy and food are inelastic necessities controlled by concentrated ownership. Climate shocks and geopolitical instability are not going away. If every crisis cycle transfers wealth upward through margin expansion on essentials, the pattern compounds. The billionaires keep the gains; the price relief, when it comes, never fully reverses the damage to household balance sheets.
