Luxembourg’s current account surplus for Q3 2025 registered €725 million, according to the latest data from the Sigmanomics database released on September 23, 2025. This figure fell short of the €-120 million estimate and declined from the previous quarter’s €883 million. The current account remains positive but shows a marked slowdown compared to the €3.68 billion peak in Q1 2025. This contraction signals a moderation in net exports and income flows, influenced by global trade dynamics and financial market conditions.

Drivers this month

• Export growth slowed amid weaker demand from key eurozone partners.
• Import volumes increased, reflecting higher energy prices and intermediate goods.
• Net primary income inflows declined, impacted by lower returns on foreign investments.

Policy pulse

The current account remains comfortably positive, supporting Luxembourg’s external balance. However, the narrowing surplus may pressure the European Central Bank’s (ECB) stance, as external vulnerabilities rise amid tightening monetary policy.

Market lens

Immediate reaction: The EUR/LU currency pair showed mild depreciation of 0.15% post-release, reflecting market caution on external balance deterioration. Sovereign bond yields edged higher, signaling increased risk premiums.

Examining core macroeconomic indicators alongside the current account reveals a complex interplay shaping Luxembourg’s external position. GDP growth moderated to 1.20% YoY in Q3 2025, down from 2.10% in Q2, dampening export momentum. Inflation remains elevated at 3.40%, driven by energy and services costs, affecting import prices and trade balances.

Monetary Policy & Financial Conditions

The ECB’s recent rate hikes have tightened financial conditions, with the main refinancing rate rising to 4.25%. This has increased borrowing costs and weighed on investment returns abroad, contributing to the decline in net primary income. Credit spreads in Luxembourg’s banking sector widened slightly, reflecting cautious sentiment.

Fiscal Policy & Government Budget

Luxembourg’s fiscal stance remains prudent, with a budget surplus of 1.80% of GDP in mid-2025. Government spending focused on infrastructure and innovation supports medium-term competitiveness, but limited fiscal stimulus constrains domestic demand growth, indirectly influencing the current account.

External Shocks & Geopolitical Risks

Heightened geopolitical tensions in Eastern Europe and supply chain disruptions have increased uncertainty. Energy price volatility, partly due to sanctions and conflict-related supply constraints, has raised import costs, pressuring the trade balance and current account surplus.

Historical comparisons highlight the volatility of Luxembourg’s current account. The €725 million surplus is well below the €2.50 billion recorded in Q3 2024 and the €2.20 billion in Q4 2024, underscoring a reversal from the elevated post-pandemic recovery phase. The current trajectory suggests normalization but also exposes vulnerabilities to external shocks.

Market lens

Immediate reaction: Following the release, Luxembourg’s sovereign bond yields rose by 5 basis points, while the EUR/LU currency pair weakened slightly. Equity markets showed muted response, reflecting anticipation of further ECB tightening and geopolitical risks.

Looking ahead, Luxembourg’s current account trajectory will hinge on several factors, including global demand, energy prices, and monetary policy developments. The base case anticipates a gradual recovery of the surplus to around €1 billion by Q1 2026, assuming stable trade conditions and moderate inflation.

Bullish Scenario (20% probability)

• Strong eurozone growth boosts exports.
• Energy prices stabilize or decline, reducing import costs.
• Improved investment income from foreign assets.

Base Scenario (55% probability)

• Moderate GDP growth with persistent inflation.
• Current account surplus stabilizes near €1 billion.
• ECB maintains cautious monetary tightening.

Bearish Scenario (25% probability)

• Geopolitical tensions escalate, disrupting trade.
• Energy prices spike further, worsening trade deficit.
• Financial market volatility depresses investment income.

Structural & Long-Run Trends

Luxembourg’s external balance is influenced by its status as a financial hub and export-oriented economy. Long-run trends suggest a gradual normalization of current account surpluses after pandemic-related distortions. Continued diversification and innovation will be critical to sustaining external resilience.

In summary, Luxembourg’s current account surplus contracted sharply in Q3 2025, reflecting a complex mix of cyclical and structural factors. While the surplus remains positive, the downward trend highlights vulnerabilities from external shocks and tighter financial conditions. Policymakers should monitor these developments closely, balancing monetary policy with fiscal prudence to support sustainable growth and external stability.
