5 instruments denominated in GBP, of which 3 publish a yield. The highest we cannot rule out is 4.17%, in Spiko Amundi Overnight Swap Fund, GBP share class (marketed as Spiko Pound / Smart Cash GBP), though nobody publishes whether you can hold it.
The central bank policy rate is 3.75% (Bank Rate). source
Every GBP instrument that publishes a yield is silent on whether its token can be transferred, so the figure above is the best we could not rule out rather than one we can tell you to go and buy. That is a disclosure gap on the issuers, not a hedge on our part, and it is the single closeable piece of work that would most improve this page.

Known size sums only the rows where AUM was obtainable, so treat it as a floor. Yields are on different bases: some are 7-day trailing, some are 30-day, some are the issuer's own displayed number, some are a supply APR that moves every block. Each row states its basis. Comparing them without reading the basis is how people get this wrong.
