LONDON, Oct 24 (Reuters) - The cost of insuring Britain's debt against default fell to its lowest since last month's "mini budget", according to data from S&P Global Market Intelligence on Monday, after Rishi Sunak won the race to become Britain's next prime minister.
Five-year sovereign credit default swaps (CDS) on UK government debt fell to 30 basis points, from 35 bps at Friday's close.
This was their lowest since Sept. 23, when outgoing Prime Minister Liz Truss and her then-finance minister Kwasi Kwarteng unveiled a fiscal plan that contained billions of pounds in unfunded tax cuts.
Sunak, who served as finance minster under Boris Johnson, said on Monday Britain faced serious economic challenges and needed stability and unity.
