On 22 September Ineos idled all three plants at its Hull site - Europe's last world-scale acetyls units. Two have already stopped; the third follows within days. The kit is mothballed "until further notice". Formally this is not a closure, but the language is blunt: Ineos chairman Sir Jim Ratcliffe called the government's energy policy "economic vandalism on an industrial scale".
The cause is not demand but gas prices; Ineos uses gas as both fuel and feedstock. By the company's framing, European gas costs 12 times more than US gas, and gas-based production 8 times more than coal-based China. The benchmarks let you check it: on 23 September TTF traded near €73 per MWh, UK NBP near 181 pence per therm and US Henry Hub at $3.02 per MMBtu. In common units that is roughly $24 against $3, or about 8 times; the 12x figure appears to be the company's read of UK industrial gas including levies.

Direct employment is 245 people, but the company counts almost 4,000 highly skilled Humberside supply-chain roles. According to the BBC, Ineos is seeking a direct US LNG contract to keep production alive. The site cut 60 jobs a year ago; in March 2026 the group reported a $593m loss and suspended its dividend for a second year, with net debt of €11.7bn.
The effect of one episode will be small: three plants are a rounding error in the consumer basket. The pattern matters more. When energy-intensive production leaves a country, inflation becomes less responsive to the policy rate. The MPC held Bank Rate at 3.75% in September, but three of nine members voted to hike.

The index is cushioned by the fact that FTSE 100 revenue is mostly foreign and a weak pound inflates it. On 23 September the FTSE 100 sat near 10,720, about 1.2% below July's record. With oil retreating and rates high, UK equities are watching crude and the Bank of England more than they are watching Hull.
Sterling has the harder story. Weak growth, a trade deficit and fleeing investment are structural negatives, and August's budget deficit hit £18.3bn against a £15.5bn forecast. On 23 September GBP/USD stood at 1.328, its lowest since late July, down 2.6% on the month. It is propped up by expectations of a November hike - support that rests on the very inflation the energy shock is partly creating.

What Britain is losing
The plants make acetic acid, acetic anhydride (a feedstock for aspirin) and ethyl acetate, a solvent. From there it feeds pharmaceuticals, clothing, cosmetics, detergents, construction materials and military explosives. Ineos stresses the units were among the world's most efficient, with a carbon footprint half that of US product and one-eighth that of Chinese output.Direct employment is 245 people, but the company counts almost 4,000 highly skilled Humberside supply-chain roles.

Inflation: a supply-side hit
It is easy to get this backwards. Losing production does not lower prices; it raises them. If acetyls now come from the US and China, you add logistics, import risk and a weak pound. This is a classic supply shock, working in the same direction as expensive oil. According to the ONS, UK inflation accelerated to 3.1% in August, and the Bank of England expects above 4% in early 2027.The effect of one episode will be small: three plants are a rounding error in the consumer basket.

The stock market and the pound
There is no direct hit to the FTSE 100: Ineos is private and its shares are not in the index. But the company's bonds slipped by as much as 1.6% on the day, according to City AM, with some issues trading 18% below face value. That reflects market doubts about the group.The index is cushioned by the fact that FTSE 100 revenue is mostly foreign and a weak pound inflates it.

⚠ IMPORTANT
Shutting Europe's most efficient plant is rational for the company and toxic for the country. Ineos moves production to where gas is cheap, while Britain gets imports with a bigger carbon footprint, a more fragile supply chain and one more reason for inflation to stick. This is not really about Hull. It is about an open, energy-intensive economy whose model stopped working once energy stopped being cheap.
