Definition

What this measures

Interest expense on the public debt outstanding for the calendar month, from the Treasury Fiscal Data dataset Interest Expense on the Public Debt Outstanding, field month_expense_amt. The dataset publishes one line per security category (accrued interest, amortized discount and premium, savings bonds, government account series); the value stored here is the sum of every line the Treasury publishes for the month, which is the total the Treasury itself reports. Monthly, US dollars.
