What Happens If Europe Crushes the Swap Market?

An interesting piece here by John Carney: What Happens if Europe Crushes the Swap Market?

An excerpt:

Many European politicians probably wouldn't mind killing the CDS market. From their point of view, the CDS market has been an unmitigated evil, allowing speculators to profit from the debt burdens of Europe's peoples. Even worse, because the bond market appears to react to widening credit spreads by pushing down the value of sovereign bonds, it appears to make government borrowing more expensive.

Some of Europe's leaders believe the CDS market is manipulated by hedge funds.

But the European leaders misunderstand the CDS market and its relationship to the bond market. The CDS market serves two important purposes: It's both a hedge for investors and an indicator of how risky the market thinks certain bonds are. Many investors are able to buy more of a country's bonds because they can reduce their risk by purchasing swaps that pay off in a default. And the price of the swaps is an indicator—albeit not always a reliable one—of the riskiness of the underlying bonds. In short, the CDS market provides liquidity and transparency to the bond market.

Take away that liquidity and transparency and governments will likely find that lenders are less likely to extend credit. With fewer opportunities to hedge, and prices based on less information, fewer investors will be willing to buy. That would mean selling bonds that have already been issued and staying out of new issues, which would ultimately push up the cost of government borrowing.
