Britain’s new finance minister Kwasi Kwarteng unleashed historic tax cuts and huge increases in borrowing on Friday in an economic agenda that floored financial markets, sending sterling and British government bonds into freefall.
Mr. Kwarteng scrapped the country’s top rate of income tax, canceled a planned rise in corporate taxes and for the first time put a price tag on the spending plans of Prime Minister Liz Truss, who wants to double Britain’s rate of economic growth.
Investors dumped short-dated British government bonds as fast as they could, with the cost of borrowing over five years seeing its biggest one-day rise since 1991, while the pound slumped more than 3 per cent against the dollar to levels last seen 37 years ago.
Economists and investors said Ms. Truss’s government, in power for less than three weeks, was losing financial credibility after it set out tax cuts and huge spending plans just a day after the Bank of England hiked interest rates to contain surging inflation.
U.S. bank Citi warned that sterling could sink to parity with the dollar. “Something has to give, and that something will eventually be a much lower exchange rate,” analyst Vasileios Gkionakis said in a research note.
Deutsche Bank said the central bank needed to make a big unscheduled interest rate hike as early as next week to calm markets and restore credibility.
Mr. Kwarteng’s announcement marked a step change in British financial policy, harking back to the Thatcherite and Reaganomics doctrines of the 1980s that critics have derided as a return to “trickle down” economics.
Ms. Truss, elected as prime minister earlier this month by a vote of the Conservative Party’s 170,000 members, has vowed to deregulate and prioritize economic growth, even if it favors the wealthy at a time when millions are struggling to cover basic household bills.
“That is how we will compete successfully with dynamic economies around the world,” Mr. Kwarteng said. “That is how we will turn the vicious cycle of stagnation into a virtuous cycle of growth.”
Speaking hours after he made his statement in parliament, Mr. Kwarteng declined to comment on the fall in sterling, saying he did not comment on market moves. “I think it’s a very good day for the UK because we’ve got a great plan,” he told reporters.
The so-called mini budget is designed to snap the economy out of a period of double-digit inflation driven by surging energy prices and a 15-year run of stagnant real wage growth.
Moves to subsidize energy bills will cost £60-billion ($65.3-billion) just for the next six months, Mr. Kwarteng said – part of a promise to support households for two years.
Tax cuts – including an immediate reduction in a property purchase tax – would cost a further £45-billion by 2026/27, he said, costs that could be recovered by a rise in annual economic growth of 1 percentage point over five years – a feat most economists think unlikely.
Britain also will accelerate moves to bolster the City of London’s competitiveness as a global financial center by scrapping the cap on banker bonuses ahead of an “ambitious deregulatory” package later in the year.
In total, the plans will require an extra £72-billion of government borrowing over the next six months alone.
“In 25 years of analyzing budgets this must be the most dramatic, risky and unfounded mini-budget,” said Caroline Le Jeune, head of tax at accountants Blick Rothenberg. “Truss and her new government are taking a huge gamble.”
The opposition Labour Party said the plans were a “desperate gamble” by a government that had delivered lower growth, lower investment and lower productivity.
“The only things that are going up are inflation, interest rates and bankers’ bonuses,” said Labour’s finance spokeswoman Rachel Reeves.
The Institute for Fiscal Studies said the tax cuts were the largest since the budget of 1972 – which is widely remembered as ending in disaster because of its inflationary effect.
On Thursday, the BoE said Ms. Truss’s energy price cap would limit inflation in the short term but that government stimulus was likely to boost inflation pressures further out, at a time when it is battling inflation near a 40-year high.
“We are likely to see a policy tug-of-war reminiscent of the stop-go 1970s. Investors should be prepared for a bumpy ride,” said Trevor Greetham, head of multi-asset at Royal London Asset Management.
Financial markets ramped up their expectations for interest rates to hit a peak of more than 5 per cent midway through next year.
Despite the extensive tax and spending measures, the government did not publish growth and borrowing forecasts from the Office for Budget Responsibility (OBR) government watchdog.
The National Institute of Economic and Social Research (NIESR) said the budget deficit looked set to rise to 8 per cent of gross domestic product during the current financial year.
The OBR forecast in March that Britain would have a budget deficit of 3.9 per cent of GDP. Mr. Kwarteng said the OBR would publish its full forecasts later this year.
“Fiscal responsibility is essential for economic confidence, and it is a path we remain committed to,” he said.
