As the dust settles on a tumultuous week for gilts (UK government bonds) and sterling – a week that has raised serious questions about chancellor Rachel Reeves’s stewardship of the economy – the big question many people will be asking is why investor sentiment has shifted so much against the UK in the past week.
Following on from that is what Ms Reeves should try to do about it.
The first point to make – and indeed it is one the government has been making – is that there has been a broad sell-off in government bonds around the world this week. Yields, which go up as the price of a bond falls, have been rising not only in the case of gilts but also on bonds issued by the likes of the US, Japan, France and Germany.
That reflects the fact that investors are changing their assumptions about the path of inflation this year and, in turn, how central banks like the US Federal Reserve, the European Central Bank and the Bank of England respond.

Inflation is now expected to be stickier around the world due to a combination of factors, of which by far the biggest is the tariffs the incoming Trump administration is expected to introduce. Those tariffs will push up the price of goods bought by American consumers and, if America’s trading partners respond with tariffs of their own, for consumers elsewhere. US Treasuries have also been under pressure due to expectations that Mr Trump will raise US borrowing sharply.
That said, gilt yields have been rising by more than yields on their international counterparts, reflecting the fact that investors think the UK has specific issues with inflation. The increase in employer’s national insurance contributions (NICs) announced by Ms Reeves in her Halloween budget will be highly inflationary because they will push up the cost of employing people.
The chief executives of some of the UK’s biggest retailers – Lord Wolfson at Next, Ken Murphy at Tesco, Stuart Machin at Marks & Spencer and Simon Roberts at Sainsbury’s – this week repeated their warnings that these higher costs will feed through to higher prices.
Another reason why gilt yields have risen more than those of their international counterparts is the UK’s particular fiscal position and its poor growth prospects.
Yes, other countries have as poor prospects for growth as the UK or as bad a debt situation. The US national debt, for example, is 123% of US GDP while Japan has a debt to GDP ratio of 250%. The UK, with a debt to GDP ratio of just under 99%, doesn’t look so bad by comparison. However, as the market in US Treasuries is the biggest and most liquid in the world and the US dollar is the global reserve currency, investors seldom have hesitation about lending to the US government. Similarly, in the case of Japan, most of its government debt is owned by Japanese savers – encapsulated by the mythical figure of ‘Mrs Watanabe’.

The UK does not have that luxury and, accordingly, has to rely on what Mark Carney, the former governor of the Bank of England, memorably described in a 2017 speech as “the kindness of strangers” to fund its borrowing (he was talking on that occasion about the UK’s current account deficit rather than its fiscal deficit, but the point holds).
In summary, then, investors are demanding a higher premium for the added risk of holding gilts. That perceived risk – as the former prime minister Liz Truss has gleefully been pointing out – means that yields on some gilts are now even higher than they spiked following her chancellor Kwasi Kwarteng’s ill-fated mini budget in September 2022.
Investors are also sceptical about the UK economy’s ability to grow its way out of this predicament. While the government’s proposals to invest in infrastructure have been welcomed by investors, they have also noted that much of the extra borrowing being taken on by Ms Reeves in her budget was to fund big pay rises for public sector workers, which – rightly or wrongly – are not perceived to be as good a use of government money as, say, investing in improvements to roads or power grids.
So what does Ms Reeves do?
Well, as the old joke about the Irishman guiding a lost tourist puts it, she “wouldn’t start from here”. The chancellor’s big mistake was to box herself in during the general election campaign by ruling out increases in income tax, employees’ national insurance, VAT or corporation tax. She could easily, for example, have promised to unwind her predecessor Jeremy Hunt’s cut in employee’s national insurance – which was rightly recognised by most voters as a pre-election bribe.
Still, she is where she is, so the chancellor’s main job now will be to convince investors that the UK is on a stable fiscal footing. With the recent rise in gilt yields – the implied government borrowing cost – threatening to eliminate the chancellor’s headroom to meet her fiscal rules, that is likely to mean public sector spending cuts or higher taxes. The former option is more likely than the latter and not least because Ms Reeves is committed to just one ‘fiscal event’ – when taxes are raised – per year and that will be her budget this autumn.

The Bank of England is also going to have a big part to play here in reinforcing to markets its determination to bringing inflation down to its target range – which means borrowers should not expect as many interest rate cuts in 2025 as they were, say, six months ago.
The Bank may also slow the pace at which it is selling its own gilt holdings (accumulated largely during the ‘quantitative easing’ on which it embarked after the global financial crisis) which would also ease the downward pressure on gilts.
Also coming to the chancellor’s aid, in all likelihood, will be a weakening in the pound which should, all other things being equal, help make gilts more appetising to international investors.
All of this underlines though, unfortunately, that there is only so much the chancellor can do.
