The latest UK new car sales YoY figure for November 2025, sourced from the Sigmanomics database, registered a modest 0.50% increase. This is a stark deceleration from October’s 13.70% and well below the 13.00% market estimate. Over the past 12 months, the average growth rate has hovered around 2.50%, reflecting a volatile recovery trajectory since early 2025.

Drivers this month

• Rising interest rates have increased financing costs for consumers.
• Supply chain constraints persist, limiting inventory availability.
• Consumer confidence weakened amid inflationary pressures and geopolitical uncertainties.

Policy pulse

The reading sits significantly below the Bank of England’s inflation target-driven growth expectations, suggesting subdued consumer spending power and cautious lending behavior.

Market lens

Following the release, sterling (GBP/USD) depreciated by 0.30%, reflecting investor concerns over domestic demand softness. UK 2-year gilt yields rose 5 basis points, signaling expectations of continued monetary tightening.

New car sales are a bellwether for consumer spending and broader economic health. The 0.50% YoY growth contrasts with core macroeconomic indicators showing mixed signals. UK GDP growth slowed to 0.40% QoQ in Q3 2025, while CPI inflation remains elevated at 5.10% YoY. Unemployment stands steady at 4.20%, but wage growth lags behind inflation, eroding real incomes.

Monetary Policy & Financial Conditions

The Bank of England has raised interest rates to 5.25% to combat inflation, tightening credit conditions. Higher borrowing costs have dampened auto loans, a key driver of new car sales.

Fiscal Policy & Government Budget

Fiscal consolidation measures, including reduced subsidies for electric vehicles, have also constrained demand. The government’s budget deficit narrowed to 3.80% of GDP, limiting fiscal stimulus capacity.

External Shocks & Geopolitical Risks

Ongoing Brexit-related trade frictions and global supply chain disruptions continue to impact vehicle imports and production costs, adding uncertainty to the sector.

Seasonal factors and supply constraints have contributed to this uneven pattern. The October spike was partly driven by pent-up demand and promotional activity, which appears to have faded. The November print suggests a normalization or potential slowdown in consumer appetite.

Market lens

Immediate reaction: GBP/USD fell 0.30%, UK 2-year gilt yields rose 5 basis points, and FTSE 100 futures dipped 0.40% within the first hour post-release. This reflects investor caution on UK consumer demand and growth prospects.

Looking ahead, UK new car sales face a complex interplay of factors. The base case scenario forecasts modest growth of 1-2% YoY over the next six months, assuming gradual easing of supply bottlenecks and stable financial conditions.

Bullish scenario (20% probability)

• Supply chains improve rapidly.
• Consumer confidence rebounds with easing inflation.
• Government introduces targeted incentives for electric vehicles.
• New car sales grow 5-7% YoY by mid-2026.

Base scenario (60% probability)

• Supply constraints persist but moderate.
• Monetary policy remains tight but predictable.
• Consumer demand stabilizes with slow income growth.
• Sales growth remains subdued at 1-2% YoY.

Bearish scenario (20% probability)

• Geopolitical tensions escalate, disrupting trade.
• Inflation spikes further, eroding real incomes.
• Credit conditions tighten sharply.
• Sales contract by 3-5% YoY.

Risks remain skewed to the downside given global uncertainties and domestic cost pressures. However, structural trends such as the shift to electric vehicles and digital retailing offer long-term growth potential.

The November 2025 UK new car sales YoY growth of 0.50% signals a marked slowdown from recent highs. This reflects tightening monetary policy, fiscal restraint, and external shocks weighing on consumer demand. Historical volatility underscores the sector’s sensitivity to macroeconomic shifts and supply disruptions.

Policymakers face a delicate balance between controlling inflation and supporting growth. The auto sector’s performance will be a key barometer of consumer health and economic resilience in the coming quarters.

Investors and market watchers should track upcoming sales data alongside credit conditions, inflation trends, and geopolitical developments to gauge the trajectory of UK consumer demand.
