The Treasury has clashed with No 10 over proposals to offer tax breaks on UK bonds in an effort to help fund defence spending.
In recent weeks, Varun Chandra, Sir Keir Starmer’s chief business adviser, has urged the Treasury to consider a scheme that would grant inheritance tax relief to households investing in gilts, as UK government bonds are known.
The idea has been floated as officials explore a range of options to finance the Government’s flagship defence investment plan (DIP).
Mr Chandra has been examining how Britain could potentially issue so-called “war bonds” without unsettling investors.
At a meeting between government officials and defence industry leaders, officials floated the idea of issuing £20bn of non-interest-bearing gilts that would be exempt from the 40pc inheritance tax charge on death.
Money managers have told the Government that such a bond could encourage investment in UK debt before changes due next year that will bring pension pots within the scope of death taxes.
However, the Treasury has repeatedly shut down suggestions of higher borrowing and is understood to have rejected Mr Chandra’s proposals.
“If you want to borrow, you can package it up how you like, but it’s still just more borrowing,” said a senior Treasury source. “It’s not going to happen.”
Several Whitehall and City sources have expressed frustration at the Treasury’s lack of engagement with the idea.
Instead, Rachel Reeves opened the door this week to raising taxes to fund higher defence spending. The Chancellor said: “The money has to come from somewhere, and borrowing cannot always be the answer.”
It comes as total public debt approaches £3tn, prompting warnings that only a crisis involving an IMF rescue plan may force policymakers to get debt down.
Investors have urged Ms Reeves to tap the £2tn in British households’ bank accounts through a concerted drive to encourage bond ownership.
Attracting more investors from households, often referred to as “retail investors”, has the potential to help stabilise financial markets and keep a lid on the Government’s interest rate bill.
Japan, the US and Italy all have a significantly higher proportion of government debt held by retail investors and can borrow at lower rates.
Britain pays the highest interest rate in the G7 on its benchmark 10-year debt, at 4.9pc. Borrowing costs have increased across much of the world since the war in Iran began at the end of February, but the UK’s rate has risen by more than in other major economies, amid concerns that the country is more exposed to another burst of inflation.
The idea of offering tax perks for investors in UK debt has been backed by Andy Haldane, the former chief economist of the Bank of England, and Sir Nicholas Lyons, chairman of Standard Life.
City bosses insisted gilts sold with inheritance tax perks would prove extremely popular with investors. “It would fly off the shelves,” said the chief executive of one firm in the Square Mile.
The interest earned on gilts is not usually tax-free, but the bonds do not incur capital gains tax when sold.
Simon French, chief economist at Panmure Liberum, said such a scheme had the potential to be “hugely oversubscribed” given recent changes to inheritance tax rules that bring pension pots into scope.
“They would sell like Oasis tickets,” he said. “If interest is high enough then there is the potential to sell at a significant premium to standard gilts and help lower the government’s average cost of borrowing.”
Marketing these gilts as war bonds “could add to the patriot premium”, he added.
British households moved a net £12bn into cash Isas in April, with the start of the new financial year, indicating the extent of demand for tax-efficient ways to save.
Sanjay Raja, economist at Deutsche Bank, said he had spoken with the Treasury about ways to open up access to savers’ funds.
“We have said to the Treasury – we need to build a domestic investor base,” he told an event hosted by the National Institute of Economic and Social Research.
“Culturally, there is something that needs to change for us to be incentivising households to go out and say, you know what, there is a nationalistic reason for us to buy debt, we don’t want the bond markets to be pricing our debt like this.”
The idea of a campaign evokes the “Tell Sid” adverts of the 1980s, which encouraged households to buy shares in the newly privatised British Gas.
Moyeen Islam at Barclays said: “It is actually quite difficult for people to buy gilts; there is no Treasury Direct thing,” he said, referring to the American site for purchasing US government bonds.
“It is more than three clicks on an app, so if you can simplify that process of ownership for households, maybe that would help.”
A Treasury spokesman said: “There is a range of options for retail investors who wish to own gilts. Underlying demand for the UK’s debt is strong with a well-diversified investor base.”
A government spokesman said: “DIP will deliver the best equipment and technology into the hands of our frontline forces at speed, while investing in and growing the UK economy.
“We are working across government to finalise the plan, and as the Defence Secretary said last week, the Prime Minister is determined to publish it before the Nato Summit.”
Four leading AI models discuss this article
"Treasury veto raises odds of tax-funded defence spending, pressuring UK growth more than markets currently price."
Treasury's rejection of IHT relief on £20bn war bonds underscores resistance to any borrowing increase despite £3tn debt and 4.9% 10-year yields. This forces reliance on tax rises or spending cuts for the defence plan, limiting scope for retail inflows that have lowered costs in Japan and Italy. Household cash ISAs hit £12bn in April, showing latent demand, yet without simplified access or perks the UK stays exposed to inflation-driven rate spikes post-Iran conflict. The clash risks delaying DIP rollout ahead of the NATO summit.
The Treasury may correctly judge that IHT perks would merely re-label existing debt without new net buyers, leaving yields unchanged while complicating future fiscal rules.
"War bonds with inheritance tax relief are unlikely to meaningfully lower DIP funding costs due to revenue losses, administrative hurdles, and uncertain retail demand."
The article frames a 'war bonds' concept—tax-incentivised gilts via inheritance tax relief—as a rapid fix to fund the Defence Investment Plan and widen the retail investor base. The strongest counter is that, even if approved, the revenue forgone from inheritance tax plus onboarding and admin costs could offset any borrowing-cost relief, and the Treasury’s pushback signals this isn’t a durable policy fix. UK retail uptake remains unproven, and turning debt management into a political gimmick risks mispricing, especially with DIP scope and revenue impact unclear. Without clear DIP sizing, the scheme may end up branding without meaningful improvement to debt affordability or market stability.
If designed well, the policy could unlock a large, stable retail bid and materially lower gilt yields, especially in a high-rate environment; Treasury resistance could weaken only as a negotiating stance, not a verdict. The upside, if realized, could overshadow the headline politics.
"War bonds are a fiscal distraction that obscures the urgent need for structural debt consolidation rather than creative accounting."
The Treasury is correct to reject 'war bonds' as a fiscal gimmick. This proposal is essentially a tax-expenditure shell game; by offering inheritance tax (IHT) relief to incentivize gilt purchases, the government would merely trade long-term tax receipts for short-term liquidity. With UK public debt nearing £3tn, the market needs structural fiscal discipline, not retail-focused 'patriotic' debt products that distort price discovery. While retail participation could theoretically lower borrowing costs, the 'patriot premium' is a myth that fails to address the G7-leading 4.9% cost of 10-year debt. Investors should view this as a sign of desperation in No 10, signaling that the government lacks a credible path to deficit reduction.
If retail bonds successfully capture the £2tn in stagnant household savings, the resulting 'stickier' domestic investor base could reduce the UK's vulnerability to volatile foreign capital flows during geopolitical shocks.
"The UK faces a structural fiscal gap that neither borrowing tricks nor retail schemes can close, and the government's policy paralysis (rejecting war bonds but not committing to tax rises) will eventually force a credibility test in gilt markets."
The Treasury's rejection of war bonds signals fiscal orthodoxy is winning over political expediency—a near-term positive for GBP and gilts, since it rules out gimmicky debt packaging that could spook foreign holders. But the deeper story is troubling: UK gilt yields at 4.9% (highest in G7) already price in skepticism about debt sustainability. The government is boxed in—can't borrow cheaply via gimmicks, won't raise taxes aggressively enough to close the gap, and retail investor schemes (Japan model) take years to build. This suggests either a painful fiscal consolidation ahead or a slow-motion loss of credibility with bond markets. The £3tn debt ceiling and pension tax changes create urgency, but the policy response looks reactive, not strategic.
The Treasury's hard line may actually be the right call: war bonds could trigger a 'crowding out' effect where retail savers buy gilts instead of equities or productive assets, ultimately weakening long-term growth and making debt service harder. Appearing fiscally serious might be worth more to markets than a £20bn gimmick.
"Rejecting war bonds risks higher yields from foreign reliance before NATO summit despite preserving short-term credibility."
Gemini's dismissal of retail bonds as a gimmick overlooks the £12bn April ISA inflows Grok cited, which could scale if IHT relief targets the £2tn household savings pool without new net borrowing. The real risk unmentioned is that rejecting this now forces reliance on foreign buyers amid Iran conflict volatility, pushing 4.9% yields higher before the NATO summit. Treasury's stance may preserve credibility but at the cost of missing a window to lock in domestic funding.
"Without explicit DIP sizing and governance guardrails, a targeted IHT relief for war gilts risks becoming a short-term illusion that wastes capital and fuels inflation."
Gemini’s 'patriot premium' rejection assumes retail demand is transitory and ignores that targeted IHT relief could tilt households into longer gilts with durable funding effects if the program is well-structured and costs are transparent. The real risk is design: admin costs, leakage to tax planning, and a mismatch between DIP sizing and retail uptake could waste capital and leave yields elevated. Without sizing and governance guardrails, the policy could be a short-term hinge with long-term inflation risk.
"Retail-focused war bonds risk crowding out private sector investment, harming long-term growth and debt sustainability."
Grok and ChatGPT miss the structural reality: the £2tn in household savings is already largely invested in UK equities or property. Shifting this into gilts via IHT relief isn't 'new' funding; it’s a capital reallocation that risks starving the private sector of growth capital. By incentivizing retail to park cash in government debt, the Treasury would effectively be crowding out productive investment, potentially suppressing long-term GDP growth and ultimately worsening the debt-to-GDP trajectory that already keeps yields at 4.9%.
"Crowding-out only matters if the £2tn is already working; hoarded cash in ISAs suggests it isn't."
Gemini's crowding-out thesis assumes £2tn household savings are already fully deployed—they're not. April ISA data shows cash hoarding, not equity saturation. The real question: does IHT relief on gilts pull idle cash or displace productive investment? If it's the former, Gemini's GDP suppression risk evaporates. If the latter, yields stay elevated anyway because markets price in lower growth. Treasury's silence on which scenario they fear is the actual problem.
