Bank of England (BoE) speeches are too hard for most people to read - and the central bank should learn from American children's author Dr Seuss, a BoE staff member wrote on Tuesday.
Dr Seuss - best known for books such as The Cat in the Hat and Green Eggs and Ham - used a vocabulary of as few as 50 words per book to help children learn to read.
While the BoE need not go quite that far, it should still try harder to make its publications understandable to the British public, BoE researcher Jonathan Fullwood said.
"Those writing in the financial industry tend to use long words. They put those long words in long sentences. And those long sentences in long paragraphs," Mr Fullwood wrote in a blog for BoE staff.
Arguments that the BoE's work is inherently complex - trying to pin down concepts like quantitative easing (QE) or a 'non-accelerating inflation rate of unemployment' (NAIRU) - cut little ice with Mr Fullwood.
Nobel Prize-winning physicist Richard Feynmann's lectures on quantum mechanics and novels by Charles Dickens and F Scott Fitzgerald were less linguistically complex than the BoE's typical output, Mr Fullwood said.
Based on estimates of average reading ability, 80 percent of the public would struggle with an average BoE publication. Reports published by financial analysts in the private sector were only slightly clearer.
"The world of finance still has some work to make its writing truly accessible," Mr Fullwood said.
BoE chief economist Andy Haldane said earlier this year that the financial sector needed to communicate more clearly to rebuild trust with the public, and suggested banks should publish simplified annual reports for customers.
Newspaper articles were accessible to about half the population, while a typical political speech only required a basic-to-intermediate degree of literacy to understand.
The conclusions on readability were based on measures previously developed by academics which take into account sentence length and the average number of syllables per word.
