Despite a murky outlook for Britain's economy, the Bank of England has opted to hold rates at 0.5 per cent, delivering a surprise to the markets.
Going into Thursday, traders were pricing in an 80-per-cent chance the central bank would slash rates to a new record low.
The last time traders flubbed on a major British decision? Three weeks ago, with the British referendum.
In the days preceding the vote, British stocks and the pound rallied, signalling the market's view that Britons would opt to remain in the European Union. Stocks and sterling plummeted when the opposite outcome came to fruition.
