US Goverment Deficit Forecast

The CBO has raised the US government's deficit forecast for Fiscal Year 2024 from $1.5 trillion to $1.9 trillion, or 6.7% of GDP.
This would be the highest deficit since 2021 when the deficit hit $2.8 trillion in response to pandemic lockdowns.
By 2034, the deficit is expected to reach $2.9 trillion or 6.9% of GDP, totaling a whopping $22.1 trillion over the 2025-2034 period.
The CBO projection also assumes that net interest will reflect over 50% of the budget deficit over the next decade.
These numbers all assume no recessions and lower interest rates.
What happens if rate cuts are delayed and a recession hits?
