Four charts tracking the fiscal trajectory of the United States
Net interest payments as % of federal revenue - the credit-analyst view of debt sustainability
Government debt/GDP vs interest burden - where the US sits among peers. Bubble size = fiscal deficit.
Interest expense vs primary deficit (ex-interest) as % of GDP - separating structural from debt-service costs
Treasury securities outstanding by holder - quarterly, Fed Z.1 data
