Economist João Rodrigues de Santos warns that a public guarantee scheme is encouraging young people to take on mortgages with high repayments and minimal financial headroom, just as Portugal faces major international uncertainty. With wages among the third‑worst in the EU, the end of pandemic-era supports and the prospect of rising interest rates, many borrowers — including first-time buyers and expats — are exposed to rapid financial distress. The combination of weak income growth, a heated property market and policy incentives to lend underestimates downside risks; the commentator argues for tighter underwriting, better safety nets and targeted borrower support to reduce systemic vulnerability.

Update: The economist reiterated in a CNN Portugal piece that the public guarantee is actively pushing young buyers into mortgages with high repayments and little buffer amid heightened international uncertainty. He highlighted that the withdrawal of pandemic-era supports and the prospect of rising interest rates mean many borrowers — notably first-time buyers and expatriates — could rapidly fall into financial distress, strengthening his call for stricter underwriting standards and targeted safety nets to contain systemic risk.
