Bank of Portugal Downgrades 2026 Economic Growth Forecast to 1.8 Percent as Iran War and Storm Damage Take Their Toll

Portugal's central bank delivered a sobering economic update this week, slashing its 2026 GDP growth forecast from 2.3 percent to just 1.8 percent — a dramatic downgrade driven by the ongoing Iran war, rising energy prices, and the lingering effects of January and February's devastating storms.

Speaking at a press conference Wednesday to present the Bank of Portugal's March Economic Bulletin, Governor Álvaro Santos Pereira warned that even the revised 1.8 percent figure might be optimistic. In an adverse scenario — one the central bank now considers increasingly plausible — Portugal's economy could grow by less than 1.5 percent this year, while inflation accelerates past 4 percent.

Why the Downgrade?

The Bank of Portugal's December 2025 forecast assumed a relatively stable global economic environment. That assumption collapsed in early 2026.

The escalating conflict in Iran has sent oil prices soaring, disrupting global supply chains and fueling inflationary pressure across Europe. Portugal, like the rest of the eurozone, is particularly vulnerable: the country imports virtually all of its energy, and higher fuel costs ripple through the economy — from transport to food to manufacturing.

Domestically, the picture is equally bleak. The winter storms that battered Portugal's central regions in January and February caused widespread damage to infrastructure, agriculture, and small businesses. The Bank of Portugal estimates the economic toll rivals or exceeds the 2017 wildfires — but the full scale of the damage remains unclear, with "limited information" about losses and the impact of government support measures.

The central bank now projects Portugal's economy stagnated in the first quarter of 2026, with zero percent growth compared to the previous quarter. That's a sharp deceleration from the 0.9 percent quarterly expansion recorded in Q4 2025.

The Adverse Scenario: Below 1.5 Percent Growth, Inflation Over 4 Percent

What makes this forecast particularly concerning for expats is the Bank of Portugal's explicit acknowledgment that its "baseline scenario" — the 1.8 percent growth figure — may already be outdated.

The European Central Bank (ECB) released its own forecasts last week, projecting 0.9 percent growth for the eurozone in 2026 and 2.6 percent inflation. But the ECB also modeled two darker scenarios: an "adverse scenario" with 3.5 percent inflation, and a "severe scenario" with 4.4 percent inflation and just 0.5 percent growth — potentially tipping the eurozone into a summer recession.

Sources inside the ECB told Bloomberg and Reuters that even the baseline scenario was considered "outdated" by policymakers, because it relied on data available only through March 11 — before the latest escalation in the Middle East.

The Bank of Portugal's forecast suffers from the same time lag. Governor Santos Pereira confirmed the Portuguese bulletin used data through March 13 — meaning it, too, is already behind the curve.

When pressed by journalists to quantify the adverse scenario for Portugal, Santos Pereira said the downside risks would be "proportional" to those outlined by the ECB. Applying the ECB's adverse scenario adjustments — a 0.4 percentage point reduction in growth and a 1.8 percentage point increase in inflation — Portugal's economy could expand by just 1.4 percent in 2026, while inflation climbs to 4.6 percent or higher.

What This Means for Expats

For expats living in Portugal or considering a move, the revised forecasts carry several important implications:

1. Higher Interest Rates Are Back on the Table

The ECB had been expected to continue cutting interest rates through 2026 to stimulate growth. Those plans are now in question. ECB President Christine Lagarde said last week the central bank may need to raise rates again — potentially as soon as April or June — if inflation remains elevated, even if the spike proves temporary.

Governor Santos Pereira urged caution, noting that today's economic environment is "very different" from 2022, when inflation was already at 5 percent before Russia invaded Ukraine. Today, inflation sits at 2 percent — the ECB's target. But he acknowledged the ECB must be "ready to react to any eventuality."

Translation: If you're carrying a variable-rate mortgage or considering buying property in Portugal, budget for the possibility of higher monthly payments by mid-year. Fixed-rate mortgages, if available, may be worth exploring.

2. Cost of Living Pressures Will Intensify

Even in the baseline scenario, the Bank of Portugal expects inflation to accelerate from 2 percent to 2.8 percent in 2026. In an adverse scenario, it could exceed 4 percent.

That means expats — particularly retirees on fixed incomes — will face continued erosion of purchasing power. Food, fuel, and utilities are likely to see the sharpest increases, as energy price shocks filter through the economy.

3. Government Support May Be Targeted, Not Broad

Governor Santos Pereira also pushed back against calls for blanket cost-of-living relief measures, such as reintroducing the "IVA Zero" (zero VAT) policy on essential goods that Portugal implemented during the 2022 energy crisis.

He argued that such policies are "easy" politically but economically inefficient, because they help everyone — including those who don't need it — while potentially fueling further inflation. Instead, he urged the government to adopt "targeted and temporary" support measures focused on the most vulnerable households.

Expats should not expect a return to broad VAT cuts or fuel subsidies. If you're financially secure, you'll likely be paying full price.

4. Job Market and Wage Growth May Soften

Slower economic growth typically means fewer job opportunities and weaker wage growth. For expats working in Portugal or seeking employment, the revised forecasts suggest a more competitive labor market ahead — particularly in sectors tied to tourism, construction, or export industries.

On the flip side, Portugal's chronic labor shortages in tech, healthcare, and hospitality may provide some insulation. But don't expect the aggressive salary increases or signing bonuses that characterized 2024 and 2025.

The Bigger Picture: Europe's Economic Crossroads

Portugal's downgrade is part of a broader European story. The eurozone entered 2026 cautiously optimistic, with the ECB planning gradual rate cuts to support a modest recovery. The Iran war has upended those assumptions.

Now, central bankers face a painful dilemma: raise rates to fight inflation (and risk choking off growth), or hold rates steady and hope the energy shock proves temporary (risking a return to the inflation spiral of 2021-2023).

For Portugal, the stakes are particularly high. The country has only recently emerged from years of economic stagnation following the 2008 financial crisis and the 2020 pandemic. A prolonged period of low growth and high inflation — the dreaded "stagflation" — could derail the progress made over the past five years.

What to Watch Next

The Bank of Portugal will release its next quarterly economic bulletin in June. Between now and then, several key developments will determine whether Portugal's economy tilts toward the baseline or adverse scenario:

• Middle East developments: Any resolution — or further escalation — of the Iran conflict will directly impact energy prices and inflation expectations.
• ECB decisions: Watch the April and June ECB meetings closely. If the central bank raises rates, Portugal's mortgage and borrowing costs will rise in lockstep.
• Storm damage assessments: As spring progresses, clearer data on agricultural losses, infrastructure repair costs, and business disruptions will emerge. This will determine whether Q2 sees a rebound or continued stagnation.
• Government policy response: Will Lisbon resist blanket subsidies and focus on targeted relief, as the Bank of Portugal recommends? Or will political pressure force broader — and potentially inflationary — measures?

Planning in Uncertainty

For expats, the revised forecasts underscore the importance of financial flexibility. Here are a few practical steps to consider:

• Review your mortgage: If you're on a variable rate, model what a 0.5-1.0 percentage point rate increase would do to your monthly payment. Can you absorb it? If not, explore fixed-rate options.
• Build cash reserves: Higher inflation and slower growth mean unexpected expenses (car repairs, medical bills, home maintenance) will hit harder. A six-month emergency fund is prudent.
• Diversify income streams: If you're reliant on a single employer or client, now is the time to build backup options. Freelance gigs, remote work opportunities, or rental income can provide cushioning.
• Monitor cost-of-living trends: Track your household spending month-to-month. Identify where inflation is hitting you hardest, and adjust accordingly. Bulk buying non-perishables, carpooling, or shifting to cheaper grocery brands may sound small, but they add up.

The Bank of Portugal's downgrade is a reminder that Portugal, for all its sunshine and charm, is not immune to global economic headwinds. The country remains a fantastic place to live — but 2026 will test the resilience of households, businesses, and policymakers alike.

Expats who plan ahead, stay informed, and maintain financial discipline will weather the storm. Those caught off-guard may find the year ahead considerably more challenging. (Background: see our piece on the IMF Article IV mission to Portugal in May 2026.)
