# Bank of England API
> Live official UK monetary data from the Bank of England's Interactive Database — no key, nothing cached. The bank-rate endpoint returns Bank Rate, the official interest rate the Bank of England sets to steer the UK economy (currently 3.75%), with the date it took effect and recent history. The sonia endpoint returns SONIA, the Sterling Overnight Index Average — the sterling overnight benchmark that has replaced GBP LIBOR and underpins trillions of pounds of contracts — with its recent path. The gilt-yields endpoint returns the UK government bond (gilt) nominal par-yield curve at 5, 10 and 20 years with the 20y-5y slope. Everything is the Bank of England's own published series. This is the sterling-rates layer for any fixed-income, forex, UK-markets or macro app that needs authoritative GBP rates. Live from the Bank of England, nothing stored. Distinct from the ECB, Fed, Bank of Canada and Norges Bank APIs — this is the UK's Bank Rate, the SONIA benchmark and gilt yields. 4 endpoints.
