Greek sovereign debt regained investment grade in 2023 from S&P and has since been confirmed by Moody's and Fitch. The slower-moving but more consequential change has been at the bank level. Alpha, Eurobank, NBG and Piraeus — the Big Four — have systematically reduced non-performing exposures to single-digit ratios, restored profitability, and are now returning capital. The last leg of what was once the canonical eurozone periphery-crisis trade has effectively closed.
Key takeaways
- Greek sovereign debt is now investment grade across all three major agencies.
- NPE ratios at the Big Four are single-digit and continuing to decline.
- Bank profitability and capital return is at post-crisis highs.
- The historical "periphery crisis trade" no longer has a Greek leg.
How the bank cleanup actually finished
A combination of HAPS (Hercules Asset Protection Scheme) securitizations, secondary NPE sales, and organic improvement in underlying credit performance produced the reduction. The pace surprised even Greek regulators — total NPE stock fell faster than scheduled in several years.
- HAPS. Government guarantee program enabled large structured sales.
- Secondary sales. Specialist NPE investors absorbed the residual.
- Underlying credit. Greek macro recovery removed marginal stress.
What it implies for the equity case
Greek banks now trade closer to European peers on price-to-book and trade above some on profitability. The deep-value periphery thesis is largely played. The current case is one of normalized European bank, not crisis recovery trade.
Why this matters for the eurozone
The political problem of the periphery has receded substantially. The systemic risk channel is no longer Greece.
Where the next periphery question is
It is not Greece. It is, increasingly, Belgium and France on debt sustainability terms.
Headline metrics
The cleanup has been comprehensive.
| Metric | 2017 | 2026 |
|---|---|---|
| Sovereign rating | CCC | BBB |
| Big Four NPE ratio | ~45% | ~4% |
| Sector ROE | negative | ~13% |
The last canonical periphery-crisis trade is closed.
Frequently asked questions
Are Greek banks fully repriced?
Largely — they trade in line with European peers now.
What is the next leg of return?
Capital return and Greek macro participation rather than crisis-recovery.
Where is the eurozone weak spot now?
It is in core debt sustainability — France in particular.
The bottom line
Greece's bank cleanup and sovereign re-rating closes the chapter that defined a decade of eurozone trading. The new periphery question is elsewhere.
