Is the primary deficit, not interest costs, the bigger fiscal problem?
Core argument: The US primary (ex-interest) deficit is much larger than its historical norm, and it is occurring at a point in the business cycle when deficits would normally be smaller than usual.
The greater challenge facing US fiscal policy is not new: the US is running a primary (ex-interest) deficit much larger than has been the case historically, and it is happening at a point in the business cycle when the deficit would normally be smaller than usual. When interest expense rose sharply in the 1980s, fiscal policymakers reacted by shrinking the primary (ex-interest) deficit. The largest fiscal adjustment from that period, enacted in 1993, would be sufficient if enacted now to offset the additional interest expense we project (relative to 2021) after 5 years. The average interest rate on federal debt is likely to remain at or below the rate of nominal GDP growth for the next decade, and this relationship is likely to be more benign than the historical average over the next five years.
