Is the FTSE 100 at a record high in 2026? Yes, repeatedly. The UK’s blue-chip index broke through the 10,000-point threshold for the first time in its history on January 2, 2026, touching an intraday peak of 10,046.25 points, and has gone on to set a string of further records through the year — reaching roughly 10,846.70 by late February and approaching 10,908 by late July, according to tracking from Trading Economics and Hargreaves Lansdown.

That run extends a strong 2025, when the index posted an annual gain of more than 20% — a performance that had already reset expectations for what UK equities could deliver after years of being treated as a laggard relative to U.S. markets.

What’s Driving the Rally

Featured Snippet Target: The FTSE 100’s 2026 rally has been driven by a combination of earnings resilience across globally diversified blue-chip companies, attractive valuations relative to international peers, expectations of further Bank of England interest rate cuts as UK inflation eases, and a weaker sterling that boosts overseas earnings for the index’s many exporter-heavy constituents.

UK inflation has been the single biggest tailwind. By mid-February, inflation had slowed to 3% — its lowest level since March 2025 — driven by falling petrol, airfare, food, and education costs, which strengthened market expectations for continued Bank of England rate cuts, according to Trading Economics. That combination of falling inflation and rate-cut expectations has repeatedly been cited as the catalyst behind individual record-high sessions throughout the year — including a session in which the index breached 8,300 points as traders returned from a long weekend pricing in additional Bank of England easing ahead of a policy meeting, per Reuters coverage carried by Yahoo Finance.

Sector leadership has rotated through the year rather than concentrating in one theme the way U.S. markets have around AI. Early-year gains were led by companies with global earnings exposure — Shell, HSBC Holdings, and AstraZeneca all posted record highs during a rally that saw the index climb 8.5% in the first two months of 2026 alone, a bounce that followed a sharp April 2025 selloff tied to that year’s “Liberation Day” tariff turmoil, according to analysis from interactive investor. Defence stocks were a standout theme later in the rally, with BAE Systems gaining roughly 4% on stronger revenue, orders, and profit, alongside gains for Babcock and Rolls-Royce, while mining names including Glencore, Antofagasta, and Fresnillo advanced as metals and precious-metals prices climbed.

The Global Comparison Matters

For context on what a 20%+ annual gain actually represents globally: the FTSE 100’s roughly 8.5% year-to-date gain by late February was only bettered among major global indices by a near-14% jump in Japan’s Nikkei 225, which was itself boosted by fiscal stimulus expectations following a change in Japanese political leadership. That places UK equities firmly in the upper tier of global index performance for 2026 — a notable reversal from the index’s reputation in prior years as an unloved, undervalued market overshadowed by U.S. technology stocks.

Individual stock winners have varied by theme. Takeover targets Beazley and Schroders posted the largest single gains among FTSE 100 constituents earlier in the year, while the mining quartet of Antofagasta, Endeavour Mining, Glencore, and Fresnillo posted gains between 27% and 33% on the back of rising metals prices. More than 40 constituent stocks registered double-digit gains through the first two months of the year alone, spanning sectors from consumer staples (Diageo) to telecoms (BT Group) to retail (Tesco).

Not Every Sector Is Winning

The rally has not lifted every FTSE 100 name. Data and information-services companies including RELX, Experian, and Sage Group have lagged the broader index — RELX shares fell by more than a fifth through the early part of the year — as investors reassessed the competitive threat AI-driven tools pose to traditional data and legal-services businesses. That divergence mirrors, on a smaller scale, the AI-driven winner-loser split playing out across U.S. markets, where AI infrastructure spenders have vastly outperformed companies whose core business AI threatens to disintermediate.

Risks to the Rally

Analysts tracking the FTSE 100’s record run through 2026 have consistently flagged the same set of risks even as the index kept climbing: heightened geopolitical tensions (particularly any escalation of the Middle East conflict affecting oil prices, which spiked to $110 a barrel at one point during the year), an unexpected resurgence in UK inflation that could stall Bank of England rate cuts, a sharper-than-expected slowdown in global growth, or an earnings-delivery breakdown among the index’s largest constituents that could unsettle broader sentiment. None of these risks had materialized meaningfully enough to derail the rally as of late summer 2026, but each remains a live catalyst that could reverse the index’s momentum.

The Bottom Line

The FTSE 100’s 2026 performance represents one of the most significant re-ratings of UK equities in years, driven by a genuine combination of falling inflation, rate-cut expectations, resilient blue-chip earnings, and a weaker pound that flatters the index’s globally-earning exporters. But the rally is not uniform — data and information-services stocks facing AI disruption have been left behind, and the same geopolitical and inflation risks that have periodically rattled global markets all year remain squarely in play for UK equities too.

Next step: Investors tracking UK equities should watch Bank of England policy meetings and UK inflation prints as the clearest near-term signal for whether the FTSE 100’s rate-cut-driven rally has further room to run.

A new Reuters poll shows 90% of economists expect the BoE to hold rates at 3.75% for the rest of 2026 — up from 83% last month. Here’s why the consensus hardened.

The Bank of England looks set to sit tight for the rest of 2026, and the consensus behind that view is getting stronger, not weaker. Per Investing.com’s coverage of the Reuters poll, the Bank will leave rates unchanged at 3.75% for the rest of the year according to a strong majority of economists, who have held that view since the war began in late February. Nearly 90% — 56 of 64 respondents — now expect no change through year-end, up from 83% last month, with six expecting a hike and two a cut; no one in the poll, conducted August 13–18, expects a September move.

Key Takeaways

• A Reuters poll of 64 economists (Aug 13–18) shows 56 now expect the BoE to hold Bank Rate at 3.75% through year-end — 90%, up from 83% last month.
• No economist in the poll expects a rate change at the September MPC meeting.
• The consensus has held since the US-Israeli war on Iran began in late February, with little evidence yet of energy-price spillover into the broader economy.
• Markets remain slightly more hawkish than economists, still pricing some chance of a rise by year-end.
• The BoE’s own guidance flags rising Q3/Q4 inflation risk tied specifically to Middle East energy prices.

The consensus is driven less by domestic demand and more by an external variable the Bank has flagged repeatedly. Per the same Reuters poll coverage, the UK economy has stayed mostly resilient since the war began, with little evidence of energy-price spillover into the broader economy — giving the Bank room to stay on the sidelines.

That resilience is fragile by the Bank’s own admission. According to an August 2026 review from Hanbury Wealth, the MPC voted six-to-three at its July 30 meeting to hold at 3.75%, with policymakers signaling rates could rise if Middle East-linked inflationary pressure intensifies; Governor Andrew Bailey said inflation had fallen faster than expected, but the conflict continues to mean high and volatile energy prices that will push inflation back up later in the year. The Bank’s own trajectory reflects this: per the House of Commons Library’s inflation briefing, based on mid-June energy pricing, the Bank projected CPI at “a little under 3%” in Q3 2026 and “a little over 3¼%” in Q4 — a downgrade from its April forecast.

There’s a genuine two-sided risk the poll’s headline framing tends to flatten. On the downside for inflation, the same House of Commons briefing notes that if Middle East energy disruption proves short-lived and oil and gas prices decline, inflation could instead fall from a September 2026 peak toward the Bank’s 2% target by Q2 2027. On the upside risk, HSBC UK economist Elizabeth Martins told Reuters (via Investing.com) that “a big rebound in energy prices would certainly change things.”

Markets aren’t as settled as the economist consensus: per the same poll coverage, financial markets are still pricing in one quarter-point rate rise by year-end — a genuine gap between what economists expect and what traders are hedging against, reported by outlets as two separate data points rather than connected explicitly.

Underlying data support a “resilient but fragile” framing. A KPMG-cited economic overview from Opus Business Advisory Group shows GDP grew 0.7% in the three months to May, slightly down from 0.8% in April, while core inflation fell more than expected in the twelve months to June, reaching its lowest rate since March 2025 — evidence the disinflation trend independent of energy hasn’t reversed. Separately, the House of Commons Library data shows food price inflation eased to 1.7% in June, its lowest since August 2024, reinforcing that the risk is concentrated in energy rather than broad-based prices.

Why It Matters

For borrowers, a prolonged hold at 3.75% keeps mortgage costs elevated relative to sharper-cut scenarios floated earlier in the year. For savers, it sustains relatively attractive cash returns. For the government, Opus’s review notes Prime Minister Andy Burnham has pledged a £2 bus-fare cap and removal of VAT from household electricity bills from October while maintaining existing fiscal rules and avoiding tax rises — a combination that gets harder to fund if borrowing costs stay elevated through year-end.

Data and Evidence

• Bank Rate: held at 3.75% since the July 30 MPC vote (6-3)
• Reuters poll: 56 of 64 economists (90%) expect no change through year-end, up from 83% last month
• BoE inflation forecast: ~3% Q3 2026, ~3.25%+ Q4 2026
• GDP growth: 0.7% in the three months to May 2026
• Food inflation: 1.7% in June 2026, lowest since August 2024

Global Impact

A UK central bank holding firm against energy-driven inflation risk is a data point other energy-importing economies — including Pakistan and much of South and Southeast Asia — are watching as a template for treating Middle East-linked price shocks as transitory.

What Happens Next

The next live decision point is the September MPC meeting, where the poll shows unanimous expectation of no change. The Q3/Q4 inflation prints will show whether the Bank’s own ~3.25% forecast materializes — and whether the hold consensus survives contact with that data.

Frequently Asked Questions

What is the UK’s current interest rate?

3.75%, unchanged since July 30, 2026.

Concern that Middle East-driven energy prices could push inflation back up in H2 2026.

Will UK mortgage rates change soon?

Based on the current poll, no near-term move is expected.

What would change the outlook?

A significant rebound — or further de-escalation — in Middle East energy prices.

Do markets agree with economists?

Not entirely — traders still price some chance of a year-end rate rise.

Four major UK forecasters — the OBR, the Bank of England-adjacent IFS, NIESR, and RSM UK — are converging on a similar diagnosis for 2026: an economy that’s avoiding outright recession but also not meaningfully growing, squeezed between resilient inflation and cautious business investment.

The Growth Numbers Are Converging Downward

RSM UK’s latest forecast puts 2026 GDP growth at just 1.0%, down from 1.4% in 2025, describing the pattern explicitly as “stagflation-lite” for a second consecutive year, with a modest recovery only expected in 2027 as inflation fades and rate cuts continue, according to RSM’s economic outlook. NIESR’s central forecast is slightly more optimistic at 1.4% GDP growth for 2026, describing the economy as beginning the year “closer to normal than at any other point this decade” despite heightened geopolitical stress, per NIESR’s winter 2026 outlook.

The Institute for Fiscal Studies frames the constraint more directly: consumption and business investment will likely stay muted as elevated uncertainty, still-restrictive monetary policy, and continued household saving all weigh on activity, with businesses “dissuaded from investing by squeezed margins and high financing costs,” according to IFS’s economic outlook.

Inflation Is Heading Back Up, Not Down

The most consequential shared theme across forecasters: inflation, which briefly dipped below 3% in early 2026, is expected to climb back toward 3.5% by year-end. RSM attributes this to a 13% rise in the energy price cap in July, higher motor fuel costs, and pass-through effects into food and goods prices, forecasting inflation to average 3.1% for 2026 overall, per RSM’s analysis. Notably, the report flags that the IMF has revised its UK inflation and growth forecasts more sharply than for any other developed economy, given Britain’s outsized reliance on gas for electricity pricing.

Bank of England Rate Path

Despite the inflation uptick, both NIESR and IFS still expect further Bank of England rate cuts through 2026. NIESR forecasts two further 25-basis-point cuts bringing Bank Rate to 3.25% by year-end — its estimate of the long-run neutral rate — following a cut to 3.75% in December 2025. IFS’s own forecast assumes Bank Rate reaches 3.5% in the first half of 2026. The divergence between continued rate cuts and rising inflation is the core tension defining UK monetary policy through the rest of the year.

Fiscal Headroom Is Nearly Gone

The Office for Budget Responsibility’s March 2026 outlook flags the tax-to-GDP ratio rising to a post-war high of 38% by 2030-31, with the November 2025 Budget having raised taxes by roughly £26 billion annually against OBR-assessed fiscal headroom of just £22 billion, according to NIESR’s reading of the same data. NIESR’s own forecast is notably more pessimistic than the OBR’s, projecting the current budget stays close to balance by 2029-30 with effectively no headroom at all — meaning public debt continues climbing toward 100% of GDP by decade’s end, sharply limiting the government’s room to respond to any future shock. RSM adds a domestic political risk on top: a Labour leadership contest raising the prospect of higher borrowing and renewed gilt yield pressure, with a short recession “not ruled out” if that risk materializes alongside global headwinds.

For UK-based investors, Deloitte notes the practical fallout includes a reduced cash ISA allowance for under-65s (down from £20,000 to £12,000) and a 2027 increase in tax on landlord property income — both tightening the traditional wealth-preservation toolkit just as broader growth conditions stay subdued, according to Deloitte’s TaxScape 2026 briefing.
