What organization would oversee the execution of a US federal government debt default, and what authorization would they be given to deal with the situation? No suggestions are offered when its scale is numerically mind numbing since the US has used debt as its drug of choice to overdose on fiscal reality.
Some outcomes will be a lowered federal bond rating by the three private bond rating agencies, where the reality of higher interest rates being offered on newly issued federal debt cannot be ignored. Federal government spending cuts in some form will be required by the realities of economic law, which includes reducing the number of federal employees, abolishing federal agencies, reducing and reforming military budgets, selling federal government property, delegating federal programs to the states, and reforming the federal entitlement programs of Medicaid, Medicare, and Social Security. Federal government tax revenue to repay the known debt with interest will rise as a percentage of each year’s future federal budget.
One real impact from a federal government debt default would be that the US dollar would no longer be the global reserve currency, with dollars in many national reserve banks coming back to the US. Holding dollars will be like holding a hot potato. Nations holding federal debt paper—like China ($859 billion), Great Britain ($668 billion), Japan ($1.11 trillion), and others as of the January 2023 numbers published by the US Treasury—as well as many mutual funds and others will see their holdings reduced in value leading to a selling off of a magnitude one cannot imagine in scale and timing. Many mutual fund holders like retirees, city and state retirement systems, and 401(k) account holders will be impacted by this unfolding event.
