Here's a quick recap of important indicators of financial market health, which all register substantial improvement, especially in the Eurozone. Even though a Greek default is a virtual certainty (Greek 2-yr yields today are 180%), these indicators suggest that the risk of contagion to other countries has dropped significantly, and the Eurozone financial system is not destined to collapse any time soon.
2-yr swap spreads are an excellent indicator of financial market liquidity and systemic risk. Spreads are down meaningfully in the Eurozone, albeit still quite elevated. U.S. spreads are now back to a level that is consistent with "normal" conditions.
Euro basis swaps reflect the difficulty that Eurozone banks are having in obtaining dollar liquidity. Funding pressures have eased significantly in the past month, leading the way to reduced swap spreads, also a measure of counterparty risk. Eurozone financial markets are exiting the danger zone when liquidity dries up and trading freezes.
2-yr yields on sovereign debt are a good measure of the market's estimation of default probabilities. Greek yields have soared, but all other countries have seen meaningful declines in the past few months. Italian 2-yr yields have fallen by half since their peak in late November. This is rather impressive.
The decline in systemic risk in the Eurozone is one reason that the U.S. equity market has been able to move higher in recent weeks, and the implied volatility of equity options has dropped to a 5 1/2 month low. As risk declines, risky asset prices rise.
