The European Sovereign Debt Crisis: When "Safe" Government Bonds Weren't
Greece, and later other eurozone countries, came close to defaulting on sovereign debt that investors had long treated as essentially risk-free — forcing a reassessment of what "safe" actually means in a currency union without a shared fiscal backstop.

What happened
Government bonds from developed economies are typically treated by markets as close to risk-free — a benchmark other assets are priced against. Starting in 2009, it became clear that Greece's government debt and deficits were far larger than previously reported, and the market began questioning whether Greece could repay what it owed.
Because Greece shared a currency with the rest of the eurozone, it could not simply devalue its own currency to ease the burden the way a country with an independent currency might. Yields on Greek bonds — the interest rate the market demanded to hold them — rose dramatically as the perceived risk of default increased, at one point exceeding 30% on 10-year debt.
The crisis spread as investors began questioning other eurozone countries with high debt loads, including Ireland, Portugal, Spain and Italy. Multiple rounds of bailouts, restructuring and, in Greece's case, an eventual default on part of its debt, unfolded over several years before the situation stabilized, with the European Central Bank's later commitment to do "whatever it takes" to preserve the currency union widely credited with calming markets.
Why it still matters
The crisis is a reminder that "safe asset" is a relative label, not an absolute one — government debt carries real credit risk that can reprice sharply when fiscal conditions deteriorate, even for developed economies.
It also illustrates correlation risk at the level of an entire currency union: eurozone assets that seemed unrelated to Greece specifically still moved together as the crisis spread, because participants realized the currency union itself connected their fates in ways that were easy to overlook during calmer periods.
