Unilever has given a dire assessment of consumer sentiment in Europe and China, two of its key markets, but raised its full year sales forecast as it lifted prices to counter soaring costs.

Like the rest of the consumer goods industry, Unilever's margins have been squeezed since the start of the war in Ukraine that has pushed up costs of energy and key ingredients.

As a result, the company has raised prices sharply.

"Consumer sentiment in Europe is at an all time low," its chief financial officer Graeme Pitkethly told reporters, warning of fears of a "confluence of events" in Europe with energy prices and inflation rising and consumers' savings waning.

Shoppers around the world paid 12.5% more for Unilever products in the quarter, with sales volumes declining 1.6%. The company reported a better-than-expected increase in third-quarter sales.

"Both the premium segments of the market and the value segments of the market are actually growing quite quickly, at an equivalent rate," Pitkethly told journalists.

But inflation and the promise of austerity in some countries has prompted a cost-of-living crisis that is pushing some people towards cheaper alternative products, such as private label goods made by retailers.

"The basic needs of our European consumers are occupying a higher share of wallets - things like utilities, transportation and food - and there tends to be cut back on discretionary non-food items," the company said.

Unilever makes more than 400 brands ranging from Persil detergent to Ben & Jerry's ice cream.

In China, Unilever's third biggest market, sales grew by 1%.

"The China number, 1%, was in fact a competitive performance in a Chinese market that is still quite subdued by continued lockdowns in China," Pitkethly said.

He added that confidence in China is lower relative to historical norms and that Unilever was not as able to increase prices in the country.

The maker of Knorr stock cubes reported underlying sales growth of 10.6%. Analysts had expected growth of 8%, a company-provided consensus showed.

Unilever said it now expects underlying sales growth for the full year 2022 to be above 8%. In July, the company said it had expected to beat its previous forecast for full-year underlying sales growth of 4.5% to 6.5%.
