Politics and news often influence economic performance. Here's what was happening at the time:

- George Washington, delivers his first State of the Union address as president.
- The Swedish navy capture a third of the Russian fleet in the Second Battle of Svensksund.
- Columbia Rediviva, returns to Boston, having become the first American ship to circumnavigate the world.
- Turkish fortress of Izmail, thought to be impenetrable, is captured by the Russians under the command of Suvorov.

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
