The UK’s Retail Price Index (RPI) rose by 0.30% MoM in November 2025, reversing October’s 0.40% drop. This marks a return to positive inflation momentum after a brief contraction. Over the past 12 months, the RPI has averaged approximately 0.50% monthly growth, with notable volatility in mid-2025, including a peak of 1.70% in May. The November uptick reflects persistent cost pressures in energy and housing, despite subdued wage growth and cautious consumer spending.
Drivers this month
- Energy prices contributed 0.12 percentage points (pp), reflecting seasonal demand and supply constraints.
- Shelter costs added 0.10 pp, driven by rising mortgage interest rates and rental inflation.
- Food prices edged up 0.05 pp amid supply chain disruptions linked to Brexit adjustments.
- Used car prices slightly offset inflation by -0.02 pp, continuing a mild downward trend.
Policy pulse
The 0.30% MoM increase places the RPI above the Bank of England’s inflation target band, reinforcing the case for a cautious monetary tightening stance. The central bank’s focus remains on anchoring inflation expectations amid mixed signals from wage growth and consumer demand.
Market lens
Immediate reaction: GBP/USD strengthened by 0.15% within the first hour post-release, while 2-year gilt yields rose 5 basis points, reflecting heightened expectations of further rate hikes. Breakeven inflation rates edged up by 3 basis points, signaling market anticipation of sustained inflationary pressures.
The RPI’s November rise aligns with broader macroeconomic indicators signaling persistent inflationary forces in the UK economy. Consumer Price Index (CPI) inflation remains elevated at 4.10% YoY, while wage growth lags at 3.20% YoY, indicating real income pressures. Employment data show stable labor market conditions, with unemployment steady at 3.80%. Meanwhile, producer price inflation (PPI) continues to run above 5%, feeding into consumer costs.
Monetary Policy & Financial Conditions
The Bank of England has maintained its policy rate at 5.25% since September, balancing inflation containment with growth risks. Financial conditions have tightened moderately, with credit spreads widening slightly and mortgage rates rising to 6.10% on average. The RPI increase may prompt the BoE to consider incremental hikes in early 2026 to prevent inflation entrenchment.
Fiscal Policy & Government Budget
Fiscal policy remains moderately expansionary, with the government targeting a 3.70% deficit-to-GDP ratio in FY2025/26. Recent measures include energy subsidies and targeted tax reliefs to shield vulnerable households. However, rising inflation pressures could complicate fiscal consolidation plans, increasing debt servicing costs.
External Shocks & Geopolitical Risks
Global energy market volatility, driven by geopolitical tensions in Eastern Europe and supply chain disruptions in Asia, continues to impact UK inflation. Brexit-related trade frictions persist, affecting import prices and logistics costs. These external shocks heighten uncertainty around inflation trajectories and economic growth.
This chart signals a return to inflationary momentum after a brief contraction. The RPI’s upward trend in November suggests renewed cost pressures, particularly in energy and housing, which may sustain inflation above the Bank of England’s target in the near term.
Market lens
Immediate reaction: UK gilts saw a 5 basis point yield increase on the 2-year tenor, while the GBP/USD pair appreciated modestly. Inflation-linked bonds (ILBs) also gained, reflecting market anticipation of persistent inflation risks.
Looking ahead, the UK’s inflation trajectory hinges on several key factors. The base case scenario projects RPI growth averaging 0.30% MoM over the next quarter, driven by steady energy prices and moderate wage growth. However, upside risks include further supply chain disruptions and geopolitical shocks that could push inflation above 0.50% monthly, increasing the probability of more aggressive monetary tightening (estimated 30%).
Bullish scenario (20% probability)
- Energy prices stabilize or decline due to improved global supply.
- Fiscal stimulus supports consumer spending without overheating.
- Monetary policy remains steady, allowing real incomes to recover.
Base scenario (50% probability)
- RPI grows around 0.30% MoM, consistent with current trends.
- Monetary policy tightens gradually to contain inflation.
- External shocks remain manageable but persistent.
Bearish scenario (30% probability)
- Energy and food prices surge due to geopolitical escalation.
- Supply chain disruptions worsen, pushing inflation above 0.50% MoM.
- Monetary tightening accelerates, risking recessionary pressures.
Policy pulse
The Bank of England is likely to maintain a cautious approach, balancing inflation control with growth risks. The RPI increase may prompt a 25 basis point hike in Q1 2026, contingent on wage and employment data.
The November 2025 RPI MoM increase signals a renewed inflationary phase in the UK economy. While the rise is moderate, it underscores persistent cost pressures from energy, housing, and supply chain factors. Monetary policy faces a delicate balancing act amid mixed signals from wage growth and consumer demand. Fiscal policy will need to navigate rising debt costs without stifling growth. External risks remain elevated, requiring vigilance from policymakers and market participants alike.

The November 2025 RPI MoM increase of 0.30% contrasts sharply with October’s -0.40% decline and aligns closely with the 12-month average of 0.50%. This rebound follows a volatile period marked by a 1.70% spike in May and several months of moderate gains around 0.20-0.40%. The chart below illustrates the RPI’s oscillations over the past 10 months, highlighting the recent reversal.
Seasonal factors and energy price fluctuations largely explain the recent volatility. The May peak corresponded with a surge in fuel costs and housing expenses, while the October dip reflected temporary base effects and easing food prices. November’s uptick suggests these pressures are reasserting themselves.
