It is more the world lost faith in you, since you're basicly out and no one knows what that means for you yet, investors move money out/stops investing. Your money becomes less worth, import prices goes up. A bit more than 50% of the UK price increase is directly due to brexit (funny thing is, that drop for only an year, costs you as much as 30 years of EU membership). Now you could say your products become cheaper worldwide, but unless the raw material is from the UK, you have to import those too.
