So it begins.
EU referendum: Moody's cut UK's credit outlook to 'negative'
The UK has had its credit rating outlook downgraded to "negative" by the ratings agency Moody's after the country voted to leave the EU.
Moody's said the result would herald "a prolonged period of uncertainty".
Meanwhile, PM David Cameron is under pressure to speed up "divorce" talks with the EU after Brussels said exit negotiations should start immediately.
EU head Jean-Claude Juncker said it was "not an amicable divorce", but it was "not a tight love affair anyway".
Moody's said the referendum result would have "negative implications for the country's medium-term growth outlook", and it lowered the UK's long term issuer and debt ratings to "negative" from "stable".
It added: "In Moody's view, the negative effect from lower economic growth will outweigh the fiscal savings from the UK no longer having to contribute to the EU budget."
It also said the UK had one of the largest budget deficits among advanced economies.
Colin Ellis, chief credit officer at Moody's, told BBC Radio 4's Today programme the UK's credit rating could have an impact on UK households in the long term.
"The government borrowing rate is normally the benchmark - it is the rate at which other interest rates in the economy are set," he said.
"A lower rating would typically correspond to higher borrowing costs, and that would be felt not just by the government but by businesses and households in the longer term."
The financial assessment came after the UK voted to leave the EU, and a defeated Mr Cameron said he would step down as leader by autumn.
Pro-Leave MP Boris Johnson is tipped as favourite to replace him.
