The Federal Shutdown as Sideshow to the Debt Problem
Niall Ferguson correctly states that "The Shutdown Is a Sideshow—Debt Is the Threat" (op-ed, Oct. 5). Financial markets teach us that over time there is a reversion to the mean or average for interest rates. As the U.S. government debt clock strikes $17 trillion, the current financing cost of the $12.6 trillion portion of interest-bearing debt is about 1.98%, or $246 billion annually. The long-term average yield on two-year and five-year Treasurys is about 5.98% and 6.25% respectively. So a simple reversion to that average would more than triple U.S. debt service costs to $750 billion annually. Since Washington seems unable to cut spending in any significant way, the additional half-trillion-dollar debt-service costs from interest rate normalization likely would be financed by borrowing.
But when markets digest that the U.S. borrows not only to offset deficits but also to cover a large portion of its outstanding debt-service costs, there could be a rude awakening and a breach in confidence in the creditworthiness of the U.S. Such a crisis would likely cause federal debt-service costs to skyrocket well above historic norms—triggering a downward-spiraling liquidity crisis ending with the U.S. government unable to finance its obligations.
