The UK’s sovereign credit rating was placed on negative outlook by Moody’s Investors Service, which said the country’s ability to set policy has weakened in the Brexit era along with its commitment to fiscal discipline.

The rating company affirmed Britain’s Aa2 long-term issuer and senior unsecured ratings. The decision comes as the UK is in the midst of an election campaign that is likely to determine the future of Brexit.

“The increasing inertia and, at times, paralysis that has characterised the Brexit-era policymaking process has illustrated how the capability and predictability that has traditionally distinguished the UK’s institutional framework has diminished,” Moody’s said in a statement.

“The decline in institutional strength appears to Moody’s to be structural in nature and likely to survive Brexit given the deep divisions within society and the country’s political landscape,” Moody’s added.

The pound extended its losses on the announcement, slipping to $1.2774 (Dh4.691) from around $1.2784 just before.

While the election will have a big impact on Brexit, this week has seen both sides escalate their spending pledges, drawing election battle lines with plans to end a decade of UK austerity.

Chancellor of the Exchequer Sajid Javid said Thursday he’ll jettison the existing fiscal rules, allowing the Conservative government to devote an extra £20 billion ($26 billion) a year to capital projects such as railways and roads if Johnson’s party is re-elected. That commitment was immediately dwarfed by Labour’s Shadow Chancellor John McDonnell, who promised an additional £55 billion a year in the first term of a Labour government.

There hasn’t been a UK downgrade by a major rating company in over two years. It is currently rated AA, the third-highest investment grade, at S&P Global Ratings and AA- at Fitch Ratings. Both have the country on negative watch.
