I have a proportion of the overall revenues that interest on debt represents. It's about seven-point-something per cent. I don't have the exact number in front of me. It will be rising to about 10% over the next few years. That's been increasing.
Before the pandemic, it was slightly above 6%, but in my lifetime it's certainly reached levels that were much higher than that. It was above 30% in the early 1990s.
Interest on the debt as a share of federal revenues used to be much, much higher. It's much lower than it used to be at its peak, but it's increased compared with the record lows it reached just before or during the pandemic.
