Executive summary

The Office for Budget Responsibility (OBR) has revised UK labour market and inflation forecasts in its spring interim update. The central projection now sees unemployment rising to a peak of 5.3% in 2026 (from 4.75% in 2025), with a return to 4.9% in 2027 and a gradual fall to 4.1% by 2030. CPI inflation is now forecast to fall to 2.3% in 2026, with inflation settling at 2.0% per year from 2027.

OBR headline forecasts and key numbers

Unemployment: 4.75% in 2025 → peak 5.3% in 2026 → 4.9% in 2027 → 4.1% by 2030.
CPI inflation: revised to 2.3% in 2026 (previously 2.5% in November); 2.0% per year from 2027.
GDP growth: averages 1.5% per year from next year in the interim projection.
Public sector net borrowing: 4.3% of GDP this year → 3.6% next year → 2.9% → 2.5% → 1.8% in 2029–30.
Debt and fiscal headroom: debt lower in every year of the forecast versus the autumn; headroom against the stability rule increased from £21.7bn to £23.6bn; headroom against the investment rule £27.1bn.

These figures reflect the OBR’s central scenario and flag significant upside and downside risks tied to geopolitical and energy-price developments.

Labour market outlook: why unemployment is rising

The forecast increase in the unemployment rate is driven primarily by weaker hiring demand and difficulties for entrants to the labour force to find work. The OBR notes subdued hiring as output falls further below the economy’s supply potential.

Implications for markets and investors:

Higher unemployment can slow wage growth and reduce household consumption, pressuring GDP and corporate earnings (relevant to FTSE-listed companies).
Sectors sensitive to consumer demand (retail, leisure, autos) may face weaker revenues; defensive sectors and high-quality dividend payers could outperform in the near term.

Inflation and energy risks

The OBR trimmed its near-term inflation forecast to 2.3% in 2026, citing falling energy and food price inflation and a loosening labour market as disinflationary forces. The forecast was finalised before recent escalations in the Middle East, meaning the path for energy prices and CPI may already be materially changed.

Market signals to watch:

Brent crude and UK gas prices: renewed strength would push CPI higher and could prompt faster Bank of England (BoE) reaction.
UK bond yields: increases in yields can raise government debt servicing costs and compress equity valuations.

Public finances and fiscal stance

The interim forecasts show a meaningful reduction in borrowing across the forecast profile. Public sector net borrowing is projected to decline from 4.3% of GDP in the current year to roughly 1.8% by 2029–30. Debt is forecast to be lower in each year compared with the autumn projection, while fiscal headroom against the government’s rules has increased.

Policy signals highlighted by the chancellor (Rachel Reeves):

A commitment to maintain fiscal rules and avoid a return to large-scale fiscal loosening.
The government characterises its approach as protecting household finances while preserving market confidence.

For institutional investors, the combination of falling structural borrowing and elevated near-term geopolitical risk suggests a focus on duration management, liquidity risk, and counterparty exposures.

Chancellor response and political context

The chancellor framed the forecasts as validation of the government’s fiscal strategy, declaring the plan "the right one" and warning against "temptation of easy answers and reckless borrowing." Opposition figures criticised the administration’s tax and growth approach, while the chancellor highlighted expected improvements in GDP per person (5.6% growth over the course of the parliament) and proposed policy priorities: deeper trade relationships, investment in innovation and AI, and regional economic rebalancing.

Political and policy watchpoints:

Any major policy reversals or new fiscal measures ahead of the next spending round would alter the OBR baseline and market expectations.
The government’s emphasis on AI, trade deals, and infrastructure could support productivity and long-run GDP, but benefits are likely to accrue unevenly across sectors and regions.

Short-term market impact and trading considerations

Equities (FTSE): elevated energy prices and weaker consumption could weigh on cyclicals; defensive sectors likely to outperform in a slowing-growth environment.
Fixed income: falling borrowing in the medium term should be supportive for gilt issuance plans, but near-term inflation and geopolitical risk could keep yields volatile.
FX: large fiscal and macro shifts historically influence sterling; renewed market stress could increase volatility against USD and EUR.

Positioning advice for professional traders and portfolio managers:

Scenario plan for a downside shock from energy-price spikes or a faster-than-expected global slowdown.
Consider tactical duration and credit quality adjustments while keeping liquidity buffers.
Re-evaluate sector exposures in FTSE and supply-chain linked equities in light of slower consumer demand.

What to watch next

1. OBR updates or revisions if energy-market pressures persist.

2. UK CPI prints and wage growth data for signs of sticky inflation.

3. Bank of England guidance on policy rates and any shift in their path.

4. Geopolitical developments in the Middle East and their impact on commodity prices.

5. Government policy announcements at the Mais Lecture and subsequent fiscal statements.

Bottom line

The OBR’s spring interim update signals a modest deterioration in the near-term labour market with unemployment now expected to peak at 5.3% in 2026, alongside lower projected inflation by 2026 but elevated near-term geopolitical risk. For professional traders and institutional investors, the update underscores the need for active scenario planning across fixed income, equity sectors, and FX as markets price the interaction between fiscal consolidation, growth, and commodity-driven inflation risks.
