Policy pulse
The current reading sits well below the European Central Bank’s inflation target zone, reflecting subdued consumer demand and tighter financial conditions. The ECB’s recent rate hikes have increased borrowing costs, dampening auto loans and leasing activity.
Market lens
Immediate reaction: The EUR/USD currency pair weakened by 0.30% within the first hour post-release, reflecting concerns over Belgium’s domestic demand. The 2-year German bund yield rose 5 basis points, signaling increased risk premia in the region.
New car registrations serve as a proxy for consumer confidence and durable goods spending. Belgium’s GDP growth slowed to 0.20% QoQ in Q3 2025, down from 0.50% in Q2, while inflation remains elevated at 4.10% YoY. Unemployment held steady at 6.50%, but wage growth has failed to keep pace with rising prices, squeezing household budgets.
Monetary Policy & Financial Conditions
The ECB’s key interest rate stands at 4.25%, up from 3.75% six months ago. Higher rates have increased auto loan costs by approximately 0.50 percentage points, reducing affordability. Credit growth to households slowed to 2.10% YoY, the weakest since 2022.
Fiscal Policy & Government Budget
Belgium’s fiscal stance remains moderately expansionary, with a 2025 budget deficit forecast of 3.10% of GDP. However, targeted subsidies for electric vehicles have been scaled back, limiting incentives for new car purchases, especially in the green vehicle segment.
External Shocks & Geopolitical Risks
Ongoing supply chain disruptions linked to Eastern European conflicts and global semiconductor shortages continue to constrain vehicle availability. Energy price volatility, driven by geopolitical tensions, further depresses consumer spending power.
Historically, Belgium’s new car registrations have correlated strongly with GDP growth and consumer confidence indices. The current -11.80% contrasts with the -4.70% recorded in May 2025 and the -10.90% in September, indicating a pattern of fluctuating demand amid macroeconomic headwinds.
This chart signals a clear downward trend in new car demand, reversing the modest recovery seen in late summer. The sector faces headwinds from rising financing costs and supply shortages, suggesting further downside risk in the near term.

Looking ahead, Belgium’s new car registrations face a complex outlook shaped by monetary tightening, fiscal adjustments, and external risks. We outline three scenarios:
Bullish scenario (20% probability)
- Supply chain normalizes by Q2 2026, easing vehicle availability.
- ECB signals pause or cut in rates by mid-2026, lowering financing costs.
- Renewed fiscal incentives for electric vehicles boost demand.
- Result: registrations improve to -2% YoY by mid-2026.
Base scenario (55% probability)
- Supply constraints persist but gradually ease.
- ECB maintains current rates through 2026.
- Modest fiscal support continues without expansion.
- Result: registrations stabilize around -7% YoY through 2026.
Bearish scenario (25% probability)
- Geopolitical tensions escalate, worsening supply chains.
- ECB further tightens monetary policy amid inflation concerns.
- Fiscal austerity reduces subsidies and consumer support.
- Result: registrations deepen decline to -15% YoY or worse.
Policy pulse
Monetary policy remains the key lever influencing consumer financing. Any shift in ECB stance will materially affect auto demand. Fiscal policy adjustments, especially in green incentives, will also be critical.
Belgium’s new car registrations YoY data for December 2025 underscores the fragility of consumer durable goods demand amid tightening financial conditions and external shocks.
