Portugal

Start with the euro. Portugal does not set an independent policy rate, so domestic credit, mortgage costs, bank margins, and public-debt service move through the Eurosystem rather than through a national central-bank reaction function ^S4,S7.

Then separate the real economy from the fiscal story. GDP growth slowed to 1.9 percent in 2025, but the public accounts still showed a surplus. That combination matters because Portugal's post-sovereign-debt-cycle credibility now rests on growth that can survive debt reduction, EU-funded investment, and higher housing costs ^S1,S6,S9.

Finally, watch tourism, services exports, manufacturing niches, and residential real estate. These sectors pull in foreign demand and capital, but they also raise questions about labor supply, rents, regional congestion, and whether investment raises productivity outside Lisbon, Porto, the Algarve, and the main coastal corridors ^S1,S8,S10.
