Markets start pricing an American default
Technical default priced in 1Y contracts
The United States sovereign credit default swap (CDS) market was long regarded as an academic backwater, an illiquid instrument traded by a handful of quantitative desks to hedge bizarre structural edge cases. In late April, however, that quiet market began flashing bright red. The spread on one-year US sovereign CDS surged past 100 basis points, eclipsing the distressed debt levels of Greece and Mexico and reaching the highest level ever recorded. While headline equity markets hovered placidly near cyclical highs, derivative markets began actively pricing a non-zero probability that the United States government will commit a technical default on its sovereign debt obligations.
The dramatic blowout in one-year CDS spreads reflects an unhedged institutional insurance panic. Institutional investors holding massive portfolios of short-dated Treasuries are buying CDS protection not because they believe the US government is permanently insolvent, but because they must hedge the mechanical risk of a payment freeze.
Pricing Technical Default
Under International Swaps and Derivatives Association (ISDA) definitions, a Failure to Pay credit event is triggered if the Treasury fails to honour a maturing coupon or principal payment within a prescribed grace period.
If political gridlock pushes the government past the X-date and Janet Yellen is forced to halt debt service, sovereign CDS contracts will trigger settlement, forcing protection sellers to deliver billions in cash compensation. The CDS market is pricing the probability of operational paralysis, not sovereign bankruptcy.
The Inversion of Trust
The supreme irony of the CDS surge is that the very instrument used to hedge a US default is itself denominated in US dollars and cleared through institutions whose solvency depends on the US Treasury benchmark.
If the world’s risk-free benchmark fails, the entire derivative clearing apparatus will be thrown into legal and operational chaos. The surge in US sovereign CDS past 100 basis points is an astonishing institutional milestone; even if Washington resolves its debt ceiling at the eleventh hour, the mere fact that markets priced an American default damages the structural premium of the world's reserve currency.
