The Bank of England’s (BoE) latest Interest Rate Decision on September 18, 2025, maintained the policy rate at 4.00%, unchanged from August and in line with the Sigmanomics database consensus. This steady stance follows a series of hikes earlier in the year, peaking at 4.50% in February and March before gradual easing to the current level. The decision reflects a cautious approach amid moderating inflation and mixed economic signals.

Drivers this month

• Headline inflation eased to 5.10% YoY in August, down from 5.60% in July.
• Core inflation remains elevated at 4.30% YoY, indicating persistent price pressures.
• GDP growth slowed to 0.20% QoQ in Q2 2025, signaling softening demand.
• Unemployment steady at 3.80%, near historic lows.
• Energy prices stabilized, reducing cost-push inflation risks.

Policy pulse

The 4.00% rate holds the BoE’s benchmark above the pre-pandemic norm of 0.75%, reflecting a tighter monetary stance aimed at anchoring inflation expectations. The rate is still above the estimated neutral rate (~3.50%), suggesting a mildly restrictive policy. The pause signals the BoE’s intent to assess lagged effects of prior hikes before further moves.

Market lens

Immediate reaction: GBP/USD rose 0.30% within the first hour post-announcement, reflecting relief at the steady rate. UK 2-year gilt yields dipped slightly by 5 basis points, while 5-year breakeven inflation rates edged down to 3.20%, indicating tempered inflation expectations.

Core macroeconomic indicators underpinning the BoE’s decision show a mixed but cautiously optimistic picture. Inflation, while declining from mid-year peaks, remains above the 2% target, driven by sticky services prices and wage growth. Economic growth is sluggish, with consumer spending restrained by cost-of-living pressures and tighter credit conditions.

Inflation and growth trends

• Consumer Price Index (CPI) at 5.10% YoY in August, down from 5.60% in July and well below the 9.00% peak in late 2024.
• Services inflation steady at 4.80% YoY, indicating persistent underlying pressures.
• GDP growth slowed to 0.20% QoQ in Q2 2025, compared to 0.50% in Q1 and a 12-month average of 0.30%.
• Labour market remains tight, with wage growth at 4.50% YoY, above productivity gains.

Fiscal policy & government budget

Fiscal policy remains moderately expansionary, with the government running a deficit of 3.80% of GDP in FY 2024-25, slightly wider than the 3.50% forecast. Public investment programs continue, supporting infrastructure and green initiatives, but concerns persist over debt sustainability amid rising borrowing costs.

External shocks & geopolitical risks

Global uncertainties, including ongoing trade tensions and energy market volatility, continue to weigh on UK economic prospects. The recent stabilization in energy prices has eased inflationary pressures but geopolitical risks in Eastern Europe and Asia-Pacific remain potential disruptors.

What This Chart Tells Us

Market lens

Immediate reaction: UK gilts yields softened slightly post-decision, with 2-year yields down 5 bps, reflecting market confidence in the pause. GBP strengthened modestly, indicating investor relief at the absence of further hikes.

Looking ahead, the BoE faces a complex environment. Inflation is expected to continue its gradual descent but may remain above target into 2026. Growth prospects are subdued, with downside risks from global shocks and fiscal constraints. The central bank’s forward guidance suggests a data-dependent approach, with rate adjustments contingent on inflation and growth trajectories.

Bullish scenario (20% probability)

• Inflation falls rapidly below 3% by Q1 2026.
• GDP growth rebounds to 0.40% QoQ by Q2 2026.
• BoE begins rate cuts in H2 2026 to support expansion.

Base scenario (60% probability)

• Inflation declines slowly, reaching 2.50% by end-2026.
• Growth remains modest, averaging 0.20% QoQ.
• Rates held steady through 2026, with possible hikes if inflation surprises.

Bearish scenario (20% probability)

• Inflation remains sticky above 4% into 2026.
• Growth stalls or contracts, risking recession.
• BoE forced to hike rates further to combat inflation.

The September 2025 Interest Rate Decision underscores the Bank of England’s cautious stance amid a complex macroeconomic backdrop. The steady 4.00% rate reflects confidence that prior tightening is working, but vigilance remains essential given persistent inflation and external risks. Fiscal policy and geopolitical developments will be key to shaping the outlook. Market participants should prepare for a data-driven BoE, balancing inflation control with growth support.
