What is Britain’s new economic policy?

What’s happened?

The sudden defenestration of Sajid Javid as the UK chancellor last week has offered further evidence that Boris Johnson and his adviser Dominic Cummings are determined to run the most centralised administration in decades, without the bulwark of a powerful Treasury to offset the power of No. 10.

That has cheered those Conservatives who believe that Cummings’ will to “move fast and break things” is exactly what the UK needs. But it has raised anxiety levels among others, who see a creative tension between No. 10 and No. 11 Downing Street as necessary and desirable. Some commentators saw the move as a worryingly brazen power grab.

Why is it worrying?

When a chancellor quits, we should “all feel unsettled”, argues David Smith in The Sunday Times. Javid, who never got to present a Budget, is only the second to resign in recent decades (the first was Nigel Lawson, who quit in 1989 because Margaret Thatcher refused to rein in her own economic adviser, Alan Walters). In time, Rishi Sunak may prove an inspired choice as his successor. But for now, the careless loss of Javid means that we are “even more in the dark about what the government has up its sleeve”.

The Tories have a big majority and have delivered formal Brexit, but “we are a long way from the stability” those two developments should have implied. The brute fact of British politics right now is that “this government does not yet have an economic policy”, says Charles Moore in The Daily Telegraph. It is welcome that the “appalling negativity” of Philip Hammond’s anti-Brexit stay at No 11 is over, but that does not mean this government “knows what to do next”. Far too much is still up in the air.

Won’t the Budget clarify things?

Possibly. Johnson and Javid didn’t fall out over any major policy issues that have been made public – but there was a growing sense that they were pulling in opposite directions on fiscal policy. Javid was seen as a fiscal hawk who was determined to stick to the government’s self-imposed spending rules agreed last year and written into the Conservative manifesto (to keep public-sector net investment below 3% of GDP and not borrow for day-to-day spending).

By contrast, Johnson’s instincts appear to remain essentially “cakeist”: he wants to spend big on infrastructure while also keeping taxes down. The government has signalled that the existing rules would remain the “guiding principle” behind the Budget on 11 March, but financial markets took the view that the change in chancellors means we can expect a looser fiscal policy.

What might that look like?

According to Ruth Gregory, an economist at Capital Economics, the appointment of Sunak “increases the chances that new, less restrictive fiscal rules are announced, and that government policy boosts the economy by more over the next few years than we had previously thought”. She reckons the rule that obliges the Treasury to balance current spending over three years could be extended to five, giving Sunak “more leeway to splash the cash in the next few years and put off any fiscal tightening” until after the next election (most likely in 2024).

More radically, it’s possible that Sunak will scrap the balanced-budget objective and instead put an overall cap on total public-sector net borrowing, including investment.

As long as the government “could stomach a rising debt ratio”, then it might even opt for a 4% or 5% limit, rather than the 3% level in most EU countries. Alternatively, Sunak could scrap detailed rules altogether, and simply pledge to cut debt over the course of the parliament – giving him and Johnson even more fiscal freedom.

Is the UK’s fiscal credibility at stake here?

Not necessarily. The longer the current era of ultra-low interest rates lasts, the more respectable it has become to argue that the days of bond vigilantes punishing profligate governments is over, and much looser fiscal policy and higher borrowing now make perfect sense. Indeed, the reaction of financial markets to the prospect of a more expansionary chancellor was somewhere between sanguine and positive.

Gilts and the pound both rose a bit as markets bet on greater fiscal stimulus fuelling a stronger economy and nudging up interest rates. Even so, says Jeremy Warner in The Daily Telegraph, the UK can’t afford to take risks with its fiscal credibility – and junking manifesto commitments on fiscal rules just three months after the election would be risky indeed.

Johnson’s Britain is not like Trump’s America, with the “exorbitant privilege” of controlling the global reserve currency. We are a small, open economy dependent on attracting investment from overseas. We cannot “borrow with impunity from the rest of the world”.

So taxes will have to rise?

There’s been much speculation in the press in recent weeks about whether the government is considering a range of policies, including a “mansion tax” on expensive homes, a cut in pension relief (from 40% to 20%) on people earning more than £50,000, and other raids on capital gains, inherited wealth and profits.

Some of this may well be political kite-flying, or softening wealthier voters up so that whatever Sunak does unveil doesn’t seem so bad. But in the longer term, argues The Economist, “two ineluctable forces will force him to raise taxes on the rich”.

The first is fiscal: money is needed to finance ambitious infrastructure projects such as HS2, as well as the higher medical and social-care costs of an ageing population.

The second is political: the government’s policies need to appeal to the party’s new supporters in ex-Labour heartlands, as well as in the “well-heeled shires... To hold on to those northern gains, Johnsonian Conservatism will need to be more open-handed than the Cameroonian variety.” Someone has to pay for that, sooner or later.
