Can Britain Run Out of Money?

Listen to any Budget, any leadership contest, and the same picture appears: the country is a household, the Chancellor a parent at the kitchen table, the iron duty to live within our means. Every party repeats it as if it were arithmetic. A few years ago Yanis Varoufakis put the other view to a Question Time audience — a country is not a household: when one family tightens its belt its income holds, but when a whole country does, its income falls, because one person's spending is another's income. The studio bristled. Somewhere along the way the obvious had become the heresy.¹

A country is not a household.

It is hard to find a corner of British public life not infected by the idea, and it has a back-catalogue. David Cameron warned that Labour had “maxed out the nation's credit card”; the note Liam Byrne left the Treasury in 2010 — “I'm afraid there is no money” — was brandished by the next government for a decade; Theresa May told a nurse on Question Time there was no “magic money tree.” And the press repeats it as the weather. When Andy Burnham emerged as Keir Starmer's likely successor in 2026, the New Statesman judged his win through the market's eyes — “as far as the bond market is concerned, Andy Burnham chose a good day to win” — and reported it “literally hanging on every word” he said about fiscal rules. City AM tracked his scramble “to soothe skittish investors.” Sky and Bloomberg presenters recited the binary — tax rises or spending cuts, “headroom” to be built — as plain fact. The people whose job is to scrutinise power had quietly agreed on the one thing that closes the argument before it begins.^{2,3,4,5,6,7,8,9}

There isn't a magic money tree.Theresa May, to a nurse asking about NHS pay, BBC Question Time, 2017

It is not a museum piece. The orthodoxy no longer needs defending — it gets recited. As recently as this summer, a Telegraph economist wheeled it out on live television, as plainly as May said it to the nurse:

When you’re as indebted as we are, when your debts have gone up faster than any other G7 country … eighty per cent more borrowing … then you don’t have the freedom to do what you want.Liam Halligan, on live television, July 2026

None of that was always common sense — it had to be built, and you can date the construction. It begins in 1944 with Friedrich Hayek's The Road to Serfdom, the wartime bestseller that recast economic planning as the road to tyranny and made Keynesianism the enemy. Three years later Hayek gathered a few dozen like-minded economists at Mont Pelerin in Switzerland and founded the society that would carry the creed — its early bills, and Hayek's own salary, paid by the American William Volker Fund. In 1949 he set out the long game in an essay, 'The Intellectuals and Socialism': free-market ideas would win not by persuading voters but by capturing the people who shape what voters think. For two decades it was a doctrine in the wilderness, patiently funded, waiting.^11,12,13

What turned a critique into a programme was Chicago. Hayek moved there in 1950; Milton Friedman and George Stigler built what became the second Chicago School, and Friedman gave the movement its economics. He restated the old quantity theory of money in 1956; in 1963, with Anna Schwartz, he published A Monetary History of the United States, which blamed the Great Depression not on a collapse of demand but on the Federal Reserve letting the money supply contract; and in a landmark 1967 address he revived the claim that inflation is 'always and everywhere a monetary phenomenon'. Monetarism was the respectable economics — and the cover under which the wider free-market creed could travel.^14,15,16,17

Britain had its carriers ready. From the 1950s the Institute of Economic Affairs was the lone domestic voice for free markets, turning Chicago into pamphlets for politicians and journalists. Enoch Powell made the first political foray, pressing monetarist arguments as Financial Secretary to the Treasury in the late 1950s, long before they were fashionable. And in 1974, after Edward Heath's defeat, Keith Joseph and Margaret Thatcher founded the Centre for Policy Studies expressly to import Hayek into Conservative thinking. The think-tanks were the bridge from the seminar room to the manifesto.^18,19,20

Then the orthodoxy won its deepest victory — over its own enemy. By the mid-1970s, with inflation running wild, it was a Labour government that broke. Faced with a sterling crisis and forced to the IMF in 1976, Denis Healey brought in monetary targets and cash limits, converting the party of Keynes to monetary discipline; and at that autumn's conference, in a speech written by Callaghan's adviser Peter Jay, the Prime Minister told his own party that a country could no longer simply spend its way out of recession. The decisive surrender to sound money came not from the right but from the left — which is exactly what made it look, ever after, like plain necessity rather than ideology.^18,21,22

After that, installation was a formality. The IMF humiliation helped carry Thatcher into Downing Street in 1979; across the Atlantic, Paul Volcker's Federal Reserve took monetarism global with three years of punishing interest rates, and Reagan adopted it wholesale. Thatcher supplied the mythology — a line of 'eternal verities' running from Adam Smith through Hayek, as though the doctrine were not decades but centuries old. What was left, in the end, was machinery: fiscal rules, Friedman's idea of a fixed, binding constraint that bars a government from acting counter-cyclically — the device through which sound-money ideology hardens into law. A contested theory had become the air every Chancellor breathes.^22,23,24,25

The state has no money of its own — it can only spend by taxing or borrowing.Margaret Thatcher, the household analogy made doctrine

Hold that in mind — that 'living within our means' is not a neutral description of how money works but a position, with authors and a date. Everything that follows is an attempt to ask the question the dogma forecloses: is it actually true?

How the money actually moves

Start with the plumbing. The Treasury raises money by selling bonds — gilts — at auctions run by the Debt Management Office. A gilt's coupon, its interest rate, is fixed when it is issued; the yield the government actually pays is set by what investors bid, and they bid against the Bank of England's Bank Rate. The central bank sets the anchor the whole auction prices off.²⁷

Now follow that gilt to the end of its life. It matures; the Treasury must hand back the whole sum, but it has run no surplus to do so, so it doesn't. It refinances — raising a fresh gilt at the DMO's next auction, at whatever rate the market demands that day, to roll the old one over. The national debt is a stock you forever roll, not a bill you pay down. That is what makes it rate-sensitive: when the market's price moves, the cost of every refinancing moves with it — debt interest hit fifteen-year highs in 2022, and a single percentage point on Bank Rate now adds roughly £20 billion a year. That sensitivity is why the markets can bite.^{27,28,29,30,31}

Why the markets bite

On the orthodox reading, that financing structure is exactly why discipline is real. A government that must return to the market every week to roll its debt depends utterly on investors' willingness to keep buying — and that willingness rests on confidence. Lose it, and the price of the next auction rises, the cost of the whole rolling stock climbs, and the spiral feeds itself. Viewed this way, 'living within our means' is not superstition; it is prudence about the one thing you cannot control.^32,33

September 2022 is the case for the prosecution. Liz Truss and Kwasi Kwarteng announced large, unfunded tax cuts with no OBR forecast; gilt yields spiked, a pension-fund crisis forced an emergency Bank of England intervention, and the government was gone within weeks. The market had broken a Prime Minister. To the orthodox eye this settles it: there are limits, the markets enforce them, and a Chancellor crosses them at her peril.³⁴

That lesson was learned, hard, in Downing Street. Rachel Reeves has built her entire chancellorship around never being Trussed. Two rules, declared non-negotiable: the current budget in surplus by the end of the forecast, and debt falling as a share of GDP — both judged by the same OBR that Truss had bypassed, and which Reeves made a point of vowing to respect. To justify the discipline she announced a £22 billion “black hole” left by the Conservatives — the OBR would later put the hidden costs nearer £9.5 billion — and every spending fight since has hit the same wall: there is no headroom, the rules forbid it. This is the orthodoxy at its most concrete: a Chancellor armouring an entire programme against the ghosts of 2022, and the crash of 2008 before it. Which makes the next question the sharp one — is the thing she's defending against really what the market punishes?^35,36

The other reading

The second reading is the oldest theory of money there is, and it begins with a question the household analogy never asks: where did money come from? Not from barter — from the state. A ruler names a unit of account, the pound or the livre, and then levies a tax, a fee, a fine, payable only in that unit. At a stroke an otherwise worthless token becomes something everyone must obtain, because the alternative is the dungeon. Taxes drive money — the chartalist insight, set out by Georg Friedrich Knapp in 1905 and carried into economics by Keynes. Read that way, the purpose of a tax was never to raise revenue. It was to move real resources. A king with an army to feed and an empty treasury does not tax to collect coins; he taxes to compel the baker, the smith and the soldier to work for his token. The mechanism is all over the record: medieval England ran its money as notched tally sticks, the Exchequer's own IOUs, accepted because they would be taken back in tax; colonial administrators imposed a hut tax on subsistence populations who had no use for the currency precisely to force them into wage-labour to earn it. The tax did not fund the state. It conscripted the economy.^{37,38,39,40,41,42,43}

Bring that ancient logic into the present and nothing about it has changed. The British state is still the monopoly issuer of the pound, and it still levies taxes payable only in pounds — so, exactly as with the king and his tally sticks, the pounds must be spent into existence before anyone can hand them back in tax. Spending comes before taxation; the issuer of a currency is not a user of it. Which is why Truss was never going to be unable to pay: a debt owed in pounds is always serviceable in pounds — and when the gilt market seized that September, it was the Bank of England that stepped in to buy. What moved was the price investors demanded and the value of the pound — confidence and the currency, not solvency.^44,45,46

If the state never has to obtain pounds before it spends them, it can never be forced to run out of them — it can always meet an obligation in its own currency. Even the high priests of orthodoxy concede the point. The binding constraint is what those pounds can buy: spend faster than the economy can produce, and you get inflation, and inflation, not bankruptcy, is the real ceiling. A government that ‘defaults’ on debt in its own currency has chosen to.^47,48,49

Zero probability of involuntary default.Alan Greenspan, chair of the Federal Reserve, on US Treasuries

Underneath the whole argument sits an accounting identity — and it is the part the deficit panic gets exactly backwards. Add up the financial balances of the three sectors of an economy — government, domestic private and overseas — and they must sum to zero: one sector's deficit is another's surplus, by identity. Rearranged, the private sector can only accumulate financial savings if the government runs a deficit or the country runs a trade surplus. Britain runs a trade deficit, so the arithmetic is stark — the government's deficit is, pound for pound, the private sector's surplus. The debt the orthodoxy wants gone is the public's savings. Their red ink is our black ink. Which is why a deficit is better understood as a subsidy to everyone else than a burden on them: it is the state crediting the private sector with net financial assets it gets to keep. And why balancing the budget is not the safe option it sounds. A balanced budget adds nothing to private net wealth; a surplus actively drains it, forcing households and firms to run down savings or borrow to keep spending. The clearest case is the Clinton surpluses of the late 1990s, sold as the height of responsibility: with America running a trade deficit, the federal surplus pushed the private sector into record deficit — households borrowing to stay afloat — which weakened balance sheets and was followed by recession. The responsible surplus was the private fragility.^{50,51,52,53,54,55,56,57,58}

Fiscal surpluses suck money out of the economy.Stephanie Kelton

And the theory earns its keep by predicting where it should fail — and it does. There is a control group: the countries that gave up the first premise. When Greece joined the euro it stopped issuing its own money and became a user of someone else's — exactly like a household — and in the crisis its ten-year yields rocketed from under 5 per cent to nearly 30: a real solvency panic of the kind a currency issuer cannot have. Britain, the United States and Japan, still issuers of their own currencies, suffered nothing of the kind. The household analogy turns out to be true of exactly one case — the country that stopped issuing its own money.^{59,60,61,62,63,64}

What the evidence says

If the orthodox story were the whole story, the countries with the highest debt would be in permanent crisis. They are not. The United States carries debt above the size of its entire economy and borrows in the currency the rest of the world must hold; its bonds remain the global safe asset. The constraint that is supposed to be iron simply does not bind the issuer of the reserve currency.^60,65,66

Japan is the starker proof. Its government debt is around 235% of GDP — more than double Britain's — and it pays near-zero yields. It can, because the Bank of Japan holds roughly half of that debt and pins the rate, because the debt is in yen, and because it is held overwhelmingly at home. A country at more than twice the debt ratio that is meant to spell catastrophe has not defaulted, has not faced a bond strike, has for years had the opposite problem entirely.^67,68

The view from Britain

Britain does not have to imagine any of this; its own history is the proof. The national debt has sat above 100% of GDP for much of the past three centuries, and it peaked near 250% of GDP just after the Second World War — the precise moment the country chose to build the National Health Service and the welfare state. The debt did not prevent that; it funded it. And the ratio came down afterwards not through austerity but through growth, falling steadily to a low around 24% by the early 1990s. High debt, in the British record, is not the prelude to collapse — it is the signature of a state doing something large.^69,70,71

The mechanism is visible in the most recent crisis, in real time. When the government's deficit exploded during the pandemic — borrowing on a peacetime-record scale — the household saving ratio leapt from around 6% to 27.5% in a single quarter — households stuck indoors on furlough had little they could spend it on, so the money the state paid in simply banked. The deficit did not vanish into a void; it landed in the private sector as income and savings. Some of it arrived by the most direct route imaginable: furlough, which paid 80% of the wages of 11.7 million jobs across 1.3 million employers — about £70 billion — straight into people's bank accounts. And the debt those payments created is not lost either: it is held as gilts, in the pension funds and insurers that underwrite British retirements, with the Bank of England holding roughly a fifth more. The debt is the nation's savings under another name.^{72,73,74,75,76}

How did Britain carry a debt of two and a half times its national income — and then bring it down — without the bond market ever calling the shots? Because at the peak it barely used the bond market as we now imagine it. The state set the price of its own borrowing: Bank Rate was pinned at 2%, untouched since 1932, under an avowed “cheap money” policy, and Treasury bills were issued at a fixed half a per cent — a rate the banks simply had to take, because, as Keynes observed, they were “absolutely dependent on Treasury Bills for the short-term investment of their funds.” Where the market would not lend enough, the banks were compelled to, through Treasury Deposit Receipts; where that fell short, the Treasury overdrew its account at the Bank of England. The public lent too — war bonds, National Savings — but on terms the state dictated.^77,78,79

None of those tools were abolished in 1945. The government still keeps its overdraft at the Bank of England — the “Ways and Means” facility — and reached for it as recently as April 2020, when the Treasury and the Bank quietly extended it to fund the first weeks of the pandemic (the previous high had been £19.9bn, in 2008). The Bank still sets the interest rate by choice, by paying it on reserves; through quantitative easing it still holds close to a fifth of the entire debt. So when a presenter says the markets “won’t allow” a government to spend, that is not a law of economics — it is a decision: to borrow only on the gilt market’s terms and leave the rest of the toolkit on the shelf. Britain financed its largest effort, and its proudest, by taking it down.^80,81,82

Not every wartime expedient transfers. Much of the rest was external — Lend-Lease, and debts run up to the Empire, above all India — the privilege of an imperial reserve power, now long gone.⁸³

The only limit is inflation

Which raises the obvious objection: if a currency issuer cannot run out, what stops it printing without end? Real resources. New money only raises prices when spending outruns the economy's capacity to produce. Japan is the proof of the floor: through decades of deflation and idle capacity, even enormous QE and debt produced falling prices, because the new money piled up unspent. Printing into slack does not inflate.^84,85,86

Hyperinflation is the proof of the ceiling — and it shows the limit is capacity and politics, not the printing itself. Weimar Germany is the textbook case, and it does not say what the orthodoxy thinks: Germany had been shut out of the international bond market and was leaning on its central bank to meet reparations it could only pay in foreign currency, and the inflation functioned, in the end, as a form of state bankruptcy that wiped out its internal war debt. As Niall Ferguson puts it, hyperinflation is always a political phenomenon — it arrives when a state's productive base or political order has already broken, not merely because money was created. Money chases too few goods only when there are, in fact, too few goods.^87,88,89

The case that isn't even Western

If all this still sounds like a quirk of rich Western democracies, look at the country that has taken the logic furthest in the opposite political direction. China carries total debt of around 300% of GDP — far above Britain's — and faces no bond vigilantes at all, because it borrows in its own currency from a banking system the state controls. It runs the entire wartime toolkit permanently: the Communist Party directs credit through state-owned banks, captive household savings fund them, and the bond market is subordinate — yields, in the phrase of one study of the system, more fiction than fact. Capital controls keep the renminbi sovereign. A one-party state and a market democracy obey the same monetary logic — which is the surest sign the logic is structural, not ideological.^90,91,92

This is not an argument that Britain should become China. China's constraints are real and bite hard — ghost cities, zombie firms, a property bust, the slide into deflation — but they are the real-resource limits the theory predicts, not a solvency crisis; its bad debts are rolled over and restructured in its own currency, not defaulted at the market's command. And the price of its toolkit — repression, opacity, the state alone deciding who credit serves — is a bargain no democracy should want. The point is narrower and sharper: if a state built on opposite principles still cannot be forced to run out of its own money, then Britain's fear was never about economics. It was about who the money is allowed to serve.⁹³

So both readings are right about something, and the dogma obscures it. The markets do discipline — but through inflation, the currency and confidence, not through the threat of a state running out of its own money. Britain spends its fiscal arguments litigating a solvency crisis it cannot have, while the real constraints go under-discussed. 'Living within our means' is a political choice dressed as arithmetic — with authors and a date — and the more honest argument is the one it was built to prevent us from having.
