Something troubling has occurred in the market for default protection on the debt of the world's biggest borrower.
As the folks at Standard Poor's Valuation and Risk Strategies division noted in a research note Monday, the difference between the spread on U.S. sovereign credit default swaps and an equivalent benchmark for AAA-rated euro-zone sovereigns flipped into positive territory March 12. As U.S. CDS spreads expanded to their widest levels in two years, that cross-region gap blew out to 5.7 basis points last Friday before narrowing to 4.7 Tuesday.
Wider CDS spreads indicate that sellers of insurance against a particular issuer's default are charging more for it. In effect, the positive U.S.-versus-euro zone spread means investors think the risk of a U.S. default--however remote--is greater than that on euro-denominated sovereign debt.
