Instead of an explicit default, governments often employ 'financial repression.' This strategy, a 'soft default,' involves policies that lead to inflation, steadily eroding the purchasing power of citizens' savings and effectively stealing their economic value to manage national debt.

Instead of a transparent default, the U.S. government's strategy is to devalue its debt by keeping interest rates below inflation. This policy, known as 'financial repression,' erodes the real value of the dollar, effectively transferring wealth from savers and bondholders to the government to pay down its massive debt.

The endgame for unsustainable government debt is not austerity but monetization. Albert Edwards argues that political weakness and fiscal incontinence will eventually force central banks to print money to cover debts. This 'fiscal dominance' will mark a return to the double-digit inflation levels of the 1970s.

Instead of officially defaulting on unpayable promises like Social Security, governments opt for massive inflation. This devalues the currency so severely that while citizens receive their checks, the money's purchasing power is destroyed, rendering the benefits worthless without an explicit, unpopular cut.

Investor Ray Dalio explains that national debt reaches a crisis point not because of its size, but when two things happen: debt payments squeeze out essential spending, and low demand for new debt forces central banks to print money to buy it, thus devaluing the currency.

Unlike other countries, the U.S. can't truly become insolvent because, as the world's reserve currency, it can always print more dollars to pay its debts. The actual danger is that the government will devalue the currency through inflation, effectively stealing purchasing power from everyone.

The massive volume of global debt means creditors will lose value one way or another. They will either receive "haircuts" through defaults or be repaid with money that has been devalued by government printing to cover the obligations.

The underlying math of U.S. debt is unsustainable, but the system holds together on pure confidence. The final collapse won't be a slow leak but a sudden 'pop'—an overnight freeze when investors collectively stop believing the government can honor its debts, a point which cannot be timed.

Unlike emerging markets, a debt crisis in a country that prints its own currency (like the U.S. or U.K.) would not be a currency collapse. Instead, it would appear as a severe credit crunch and financial crisis, with soaring borrowing costs causing a slump in investment and economic dynamism.
