Iberian services barriers exceed 100 percent tariff equivalent
Services trade barriers between Spain and Portugal exceed a 100 percent tariff equivalent, joint Bank of Spain and Bank of Portugal research presented on October 22, 2026 finds. Goods trade and electricity markets are more integrated.
Goods advance while services lag
Bilateral goods trade rose from 0.27 percent of combined GDP in 1980 to 2.81 percent in 2024, outpacing integration gains in other European Union country pairs.
Services trade increased from 0.35 percent in 2005 to 0.55 percent in 2024 but remained comparatively limited, particularly outside travel.
Implicit barriers averaged around a 20 percent tariff equivalent for manufacturing and above 100 percent for services over 2013–2022.
The researchers find that halving barriers would raise bilateral trade and GDP.
Electricity prices differed by no more than €1/MWh in 95 percent of hours over 2015–2025.
Portuguese pumped storage absorbs Spanish midday solar production; Portugal exports electricity back during mornings and nights.
Limited mobility meets asymmetric finance
Bilateral immigrant shares were 0.19 percent in Spain and 0.22 percent in Portugal in 2025.
Movers concentrate in cities but account for larger employment shares near the border.
Spanish wages remained 49 percent higher in 2024, a gap not explained by sector, age or gender composition.
Foreign direct investment and portfolio links lag comparable country pairs; banking links are stronger.
Spain is Portugal's leading direct investment partner.
At Q4 2025, Spain accounted for 24.1 percent of Portugal's euro-area financial assets and 23.1 percent of its liabilities.
Integration has distinct limits
Electricity market integration contrasts with persistent barriers in services and limited labor mobility.
Strong banking links coexist with weaker direct investment and portfolio positions.
