Britain Gets a Mild Budget. And Welcome Clarity.

Editors’ Note: MarketMinder Europe favours no political party nor any politician. We assess developments for their economic and market implications only.

At last, after months of rumours, UK Chancellor of the Exchequer John Healey has opened his red box and released this year’s Budget. Better still, it was … boring! At least, in our opinion, and according to several headlines we saw. Reading through the relevant materials, we saw no huge changes, no major surprises. Just details and clarity on things already previewed throughout the financial news world. For markets, we think this is as fine an outcome as can be under the circumstances.

The circumstances in question are the UK’s fiscal rules, which require the projected budget deficit to be eliminated by the end of the current Parliament or within three years, whichever is further out.^[i] The arbiter is the nonpartisan Office for Budget Responsibility, which scores fiscal policy changes’ effects on revenue and spending according to its own models and assumptions. Lately, we have observed this helps stave off big tax hikes that wouldn’t generate much revenue, like wealth taxes and capital gains increases (more here shortly). But it also seems to prevent big tax cuts. Based on our reading, it isn’t fashionable today to argue broad tax cuts will stimulate growth and raise revenues.

As a result, we find the Budget is an annual exercise in tweaking fiscal policy to get projected deficits in line with forecasts. Much as we think households and businesses (and the broad economy) might benefit from big-bang tax cuts, fiscal rules generally prevent them unless spending is cut commensurately. Otherwise, they are deemed unfunded and additive to the fiscal deficit, putting finances out of balance within the allotted timeframe. Politicians know this and occasionally flirt publicly with changing the rules, but spiking bond market volatility often ends the discussion. Those market tantrums always look to us to be more about sentiment than actual debt troubles, but for politicians, we suspect that matters little. We doubt any want to be the next Liz Truss, who many observers we follow say was evicted from 10 Downing Street by bond market volatility after mere days. Thus, Budgets appear largely about adding a little austerity when forecasts require it and easing austerity a smidge when forecasts permit.

In this environment, we suspect it is impossible for any chancellor, regardless of party, to deliver a Budget everyone likes. All will probably create winners and losers—such is the nature of small tax and spending changes. Probably because everyone knows this (however subconsciously), the pre-Budget season is typically a frenzy of rumours and speculation. We see headlines warning just about every type of business or household will lose out at some point, which makes for a rather gloomy environment. We find this can weigh on stocks and discourage investment until people get clarity. Meanwhile, we think the constant leaks and rumours help markets pre-price the changes.  

Once the Budget arrives, we think markets don’t much care about whether people broadly see it as good or bad. Rather, our research finds two items tend to influence returns. One, do people finally have clarity? Two, does the Budget create surprise losers … or does it prove milder than all the rumours warned?

This Budget looks likely to grant both clarity and a mild flavour. We think clarity started trickling in this month, when the government ruled out capital gains tax hikes.^[ii] Wealth tax chatter seemingly simmered down when Treasury insiders leaked that bank tax hikes would be the main revenue raiser.^[iii] Now we have clarity in full, and the details look milder than commentators we follow warned of. Markets seemingly weren’t bothered. UK stocks were basically flat on the day, whilst bond yields were mixed.^[iv] Both are about as ho-hum a reaction as you can get. It seems a boring Budget bored markets that had long since priced rumours.

Take the bank tax. In August, several outlets reported Healey was considering a windfall profits tax (citing high interest rates as a windfall) or raising the bank corporate tax surcharge. Last month, Treasury leaks zeroed in on the surcharge, telling The Guardian a reversal of 2023’s cut was on the table.^[v] That would have taken the rate from 3% to 8%. But Wednesday, Healey announced it will rise to just 6% and be “time-limited” to 15 months from January 2027.^[vi] We think this is a negative for banks, but it is smaller than earlier reporting projected. For stocks, that seems to us like a positive surprise. 

We think relief applies across the board. Consider the broad highlights, which we pull from the Budget itself and the many supporting documents, all of which you may find at Gov.uk’s Budget hub. Taxes on rental property and savings interest income will rise another two percentage points (ppts) (on top of the two ppt hike former Chancellor Rachel Reeves already slotted) next April, but dividend taxes aren’t changing. Painful, but not as much as some commentators we follow warned was likely earlier this year. The capital gains tax exemption for selling a business will drop from £1 million to £500,000, but it gets replaced by a blanket 10% rate on lifetime gains up to £10 million for company founders. We think that is a net win for entrepreneurs. State pension payments will remain income tax-free for those living off them alone even as inflation lifts them past the £13,000 tax allowance. Another warning of trouble for households that didn’t come true.

On the savings front, not much appears to be changing. The total annual individual savings account (Isa) contribution limit stays at £20,000. But there are some tweaks. Last year, Reeves cut the cash Isa limit to £12,000 to nudge more funds into stocks-and-shares Isas and get more people to reap stock returns. But loopholes letting people hold cash tax-free in a stocks-and-shares Isa seemingly gutted the change, and Healey unwound it Tuesday. Elsewhere, the lifetime Isa, primarily intended for first-time homebuyers, will be replaced with an actual first-time buyer Isa. Contribution limits stay at £4,000 annually, and the government still offers a 25% match (with a lifetime maximum of £20,000). But the match will now be paid at withdrawal, not contribution. This prevents people from investing the government’s contribution, which many may find disappointing. But early withdrawal penalties are going away.

Business tax tweaks look mostly beneficial to us. Small businesses get more relief from business rates. Expensing allowance changes will let businesses deduct the full cost of new plants and machinery in year one, theoretically incentivising investment. Some red tape is going away, as are tariffs on over 100 food items. That likely gives supermarkets more wiggle room as the minimum wage rises 3.9%. And online marketplace platforms will now have to collect value-added tax (VAT) on behalf of sellers who use them, which adds compliance costs but helps curb avoidance and levels the playing field for brick-and-mortar shops. Again, we see winners and losers.

Elsewhere, there was very, very modest tax and energy bill relief for some households, which OBR forecasts imply rising living costs will eat up.^[vii] Prime Minister Andy Burnham’s plans to spur regional and municipal investment so far amount to letting mayoral authorities keep local business rates revenue and access federal investment loans. We see no word on how this helps towns that don’t have mayoralties, but perhaps this is just the start. Additionally, welfare and social care, two other items high on Burnham’s agenda, got punted pending further study in next year’s Spending Review.

In short , we see a raft of tweaks, newfound clarity and no major surprises. And best of all, we haven’t seen any articles cheering it. We surveyed coverage across the political spectrum. Left-leaning and right-leaning publications alike mostly panned it, as did the business leaders and economic analysts quoted in the many articles we read. Most commentators we follow deem Britain’s tax burden too high, debt too big and economic growth too slow for modest tweaks to do anything.

We think that gloom is fine for stocks. It keeps expectations low, extending the UK’s proverbial wall of worry. In this scenario, we think the UK doesn’t need rip-roaring economic growth to boost stocks. Continued modest growth would be a positive surprise, judging from headlines and forecasts. We think Budget clarity will likely be one more tailwind enabling this.
