Portugal’s December 2025 budget balance data, sourced from the Sigmanomics database, reveals a sharp fiscal deficit of -€4.30 billion. This figure is a significant deterioration from November’s -€1.30 billion and exceeds the market estimate of -€3.60 billion. The deficit level matches the June 2025 reading, indicating a return to elevated fiscal shortfalls after a brief improvement in autumn. Over the past 12 months, Portugal’s budget balance has fluctuated between -€1.30 billion and -€4.70 billion, reflecting ongoing volatility in public finances.

Drivers this month

• Increased public spending on social programs and energy subsidies.
• Lower-than-expected tax revenue amid slowing economic growth.
• Rising interest payments on government debt due to higher yields.

Policy pulse

The current deficit overshoots Portugal’s fiscal targets and EU Stability and Growth Pact guidelines. The government faces pressure to rein in spending or boost revenues to avoid further debt accumulation. Monetary tightening by the European Central Bank (ECB) raises borrowing costs, complicating fiscal management.

Market lens

Immediate reaction: The EUR/PT currency pair weakened 0.30% within the first hour post-release, reflecting investor concerns over fiscal sustainability. Portuguese 2-year bond yields rose 15 basis points, signaling increased risk premia.

Portugal’s budget balance is a critical macroeconomic indicator reflecting government fiscal health. The latest -€4.30 billion deficit corresponds to approximately 2.10% of GDP, a notable increase from the 0.60% deficit in November. This deterioration occurs amid slowing GDP growth, estimated at 0.80% YoY for Q4 2025, down from 1.20% in Q3. Inflation remains elevated at 4.50% YoY, pressuring real incomes and tax receipts.

Monetary Policy & Financial Conditions

The ECB’s recent rate hikes to 4.50% have increased Portugal’s debt servicing costs. Portuguese government bond yields have risen by 40 basis points since September, tightening financial conditions. This environment constrains fiscal flexibility and raises refinancing risks.

Fiscal Policy & Government Budget

Fiscal policy remains expansionary, with increased spending on energy subsidies and social welfare to cushion households from inflation. However, revenue growth has slowed due to weaker consumption and corporate profits. The government’s structural deficit remains above 2%, complicating compliance with EU fiscal rules.

Drivers this month

• Energy subsidy costs increased by 0.80 pp of GDP.
• Tax revenue underperformance contributed -0.50 pp.
• Debt interest payments rose by 0.30 pp due to higher yields.

Market lens

Immediate reaction: Portuguese sovereign spreads widened by 12 basis points versus German bunds, reflecting heightened risk aversion. The EUR/PT currency pair depreciated 0.30%, while short-term interest rate futures adjusted upward, pricing in further ECB tightening.

Looking ahead, Portugal’s fiscal trajectory faces multiple risks. The baseline scenario assumes moderate GDP growth of 1.00% in 2026, stable inflation near 3.50%, and gradual fiscal consolidation, resulting in a deficit narrowing to -1.80% of GDP by year-end (probability 50%).

Bullish scenario (20% probability)

• Stronger-than-expected economic growth (1.80%+), boosting tax revenues.
• Energy prices stabilize, reducing subsidy burdens.
• Fiscal reforms accelerate, improving structural balance.

Bearish scenario (30% probability)

• Economic slowdown to below 0.50% growth, depressing revenues.
• Prolonged energy price shocks increase spending.
• ECB rate hikes continue, raising debt servicing costs.

Policy pulse

Fiscal authorities face a delicate balancing act. Accelerated consolidation risks stifling growth, while inaction could erode market confidence. Coordination with ECB monetary policy will be critical to managing debt dynamics.

Portugal’s December 2025 budget balance print underscores the fragility of its fiscal position amid a complex macroeconomic environment. The sharp deficit reversal highlights the challenges posed by external shocks, monetary tightening, and structural fiscal rigidities. While short-term risks dominate, a credible medium-term fiscal strategy remains essential to restore investor confidence and ensure sustainable growth.

Continued monitoring of core indicators and market sentiment will be vital. Portugal’s ability to navigate these headwinds will influence its borrowing costs, currency stability, and broader economic outlook.
