“It’s hugely problematic,” said Jonathan Parkman, head of agricultural sales at commodities broker Marex Group. The cost increase will likely be passed on to consumers, potentially hurting US chocolate demand and making the country’s chocolate exports less competitive, he said.
The arbitrage widened as May New York cocoa prices rallied as much as 5.8% intraday to the highest price since late February. The London contract for the same month, meanwhile, cooled as much as 4.9%.

Toblerone-maker Mondelez International Inc., which has a larger share of its business in Europe, gained as much as 4.3% on Thursday, putting it among the top gainers in the S&P 500. Shares of chocolate maker Hershey Co. rose as much as 2%. The companies didn’t immediately respond to a request for comment on the impact of tariffs.
Food company Conagra Brands Inc. mentioned cocoa as one of several commodities potentially affected by Trump’s tariffs that it is exposed to. Conagra owns hot cocoa brand Swiss Miss and Duncan Hines, which makes cake and brownie mixes.
Tariffs are likely to be mostly passed through to consumers, who have already been facing waves of price hikes amid elevated cocoa prices, said Bloomberg Intelligence analyst Ignacio Canals Polo. That means chocolate makers could see fewer sales, even as the overall hit to demand may not be big enough to curb the input costs of their raw cocoa, he said.
“You’re putting even more pressure on US chocolate consumers, so that only fuels the negative volume outlook for some of these companies,” he said. “The situation is quite bad, and it’s just adding more fuel to a fire that’s already quite big.”
Cocoa grows in tropical weather areas in Africa, Asia and South America, which means US chocolate companies depend on imports. The crop grows mostly on small-size farms, in regions where farmers constantly struggle with low income.
“I find it hard to believe that they will not reconsider the cocoa example because it is not possible to grow cocoa in the US,” said Nicko Debenham, a sustainability adviser specialized in cocoa. “This is very punitive to poverty-stricken smallholder farmers.”
