The BoE’s decision to hold rates at 4.00% reflects a cautious stance amid slowing inflation and fragile growth. Since peaking at 5.00% in August and September 2024, the central bank has gradually eased monetary policy by 100 basis points. This pause aligns with the Bank’s inflation target of 2%, as headline inflation has moderated from 8.50% YoY in mid-2024 to 4.10% in August 2025. However, core inflation remains sticky at 5.00%, driven by shelter and services costs.
Drivers this month
- Inflation cooling to 4.10% YoY, down from 4.50% last month
- UK GDP growth slowing to 0.10% QoQ in Q2 2025, signaling near stagnation
- Labour market tightness easing with unemployment rising slightly to 4.30%
- Energy prices stable but geopolitical risks in Eastern Europe persist
Policy pulse
The 4.00% rate sits below the 12-month average of 4.56% but above the 3.75% level seen in early 2023. The Bank’s forward guidance signals a data-dependent approach, balancing inflation risks against growth headwinds.
Market lens
Immediate reaction: GBP/USD rose 0.30% in the first hour post-announcement, reflecting relief at the pause. UK 2-year gilt yields fell 5 basis points, while breakeven inflation rates edged down to 3.20% from 3.30% last month.
Core macroeconomic indicators reveal a UK economy at a crossroads. GDP growth has decelerated sharply from 0.40% QoQ in Q4 2024 to 0.10% in Q2 2025. Inflation, while easing, remains above target, with core inflation steady at 5.00%. The labour market shows signs of softening, with unemployment rising from 3.90% in early 2025 to 4.30% in August.
Drivers this month
- Consumer spending growth slowed to 0.20% MoM in July 2025
- Business investment contracted 0.50% QoQ, reflecting uncertainty
- Housing market activity cooled, with mortgage approvals down 8% YoY
Policy pulse
The BoE’s steady rate reflects a balancing act: inflation pressures persist but growth risks have increased. The 4.00% rate is accommodative relative to the 5.00% peak but restrictive compared to pre-pandemic levels near 0.75%.
Market lens
Immediate reaction: UK equity indices, such as the FTSE 100, gained 0.50%, signaling investor confidence in the BoE’s measured approach. The pound strengthened modestly against the euro and dollar.
Comparing the current rate with historical data, the 4.00% level is the lowest since November 2024, when the rate was 4.75%. The downward trajectory reflects the Bank’s response to cooling inflation and mounting growth concerns.
This chart underscores the BoE’s pivot from aggressive tightening to cautious stabilization. The steady 4.00% rate suggests the Bank is monitoring incoming data closely before further moves, signaling a potential pause or modest cuts ahead depending on inflation and growth dynamics.
Drivers this month
- Inflation trending downward from 8.50% to 4.10% YoY
- GDP growth decelerating to near zero
- Financial market volatility subdued post-decision
Policy pulse
The current rate aligns with the BoE’s inflation target trajectory but remains above pre-pandemic norms, reflecting ongoing inflation risks.
Market lens
Immediate reaction: UK gilt yields declined slightly, with 2-year yields dropping 5 basis points, indicating market relief. GBP/USD strengthened, reflecting confidence in the Bank’s steady approach.
Looking ahead, the BoE faces a complex environment. Inflation is easing but remains above target. Growth is fragile, and geopolitical risks, particularly related to energy supply and trade, persist. The Bank’s next moves will hinge on incoming data and external shocks.
Drivers this month
- Global energy prices stable but vulnerable to geopolitical tensions
- UK fiscal policy remains moderately expansionary with a 2025 deficit forecast of 3.80% of GDP
- Labour market softening may ease wage pressures
Policy pulse
Three scenarios emerge for the next 12 months:
- Bullish (30% probability): Inflation falls rapidly below 3%, growth stabilizes, prompting a rate cut to 3.50% by mid-2026.
- Base (50% probability): Inflation moderates slowly, growth remains sluggish, rates hold near 4.00% with minor adjustments.
- Bearish (20% probability): Inflation surprises on the upside due to energy shocks, forcing a rate hike back to 4.50% or higher.
Market lens
Immediate reaction: Forward markets price a 40% chance of rate cuts by Q3 2026, reflecting cautious optimism but uncertainty.
The BoE’s decision to hold rates at 4.00% signals a pause in monetary tightening amid easing inflation and slowing growth. Historical comparisons show a clear shift from the 5.00% peak last year, reflecting the Bank’s responsiveness to changing economic conditions. The macro outlook remains balanced, with upside risks from geopolitical shocks and downside risks from growth stagnation.
Financial markets have reacted positively, with sterling strengthening and gilt yields falling modestly. The Bank’s data-dependent approach will be critical in navigating the uncertain terrain ahead.
