Faced with massive debt, governments have five options: austerity, default, high growth, hyperinflation, or financial repression. Napier argues repression—keeping inflation above interest rates to erode debt—is the most politically acceptable path, just as it was post-WWII.

Financial repression isn't just about forcing institutions to buy government bonds. A key, subtle mechanism is making other asset classes less appealing. For example, implementing rent controls can remove the inflation-hedging quality of property, while high transaction taxes can deter equity investing, thus herding capital into government debt.
When national debt grows too large, an economy enters "fiscal dominance." The central bank loses its ability to manage the economy, as raising rates causes hyperinflation to cover debt payments while lowering them creates massive asset bubbles, leaving no good options.
According to hedge fund manager Ray Dalio, the only historical path out of a terminal national debt cycle is a "beautiful deleveraging." This requires a painful but precisely balanced mix of austerity, debt forgiveness, wealth taxes, and printing money to avoid societal collapse.
Global governments are actively pursuing policies (running economies hot, suppressing energy costs, managing rates down) to create a period of artificial prosperity. This is a deliberate strategy to push a massive debt sustainability crisis further into the future, which will feel great until it doesn't.
In a democracy with massive debt, reckless government spending becomes inevitable. The electorate will consistently vote for short-term relief (money printing, free programs) over the long-term pain of austerity, making fiscal irresponsibility a predictable outcome of human nature.
The central strategy in macroeconomics is to stifle volatility in foundational markets like bonds and foreign exchange. This engineered stability allows nominal GDP to outpace debt, effectively devaluing it over time. This delicate balance is most vulnerable to unpredictable geopolitical shocks that can shatter the low-volatility regime.
Tyler Cowen predicts the US will eventually resort to several years of ~7% inflation to manage its national debt. This strategy, while damaging to living standards, is politically more palatable than raising taxes or cutting spending. Rapid, AI-driven productivity growth is the only plausible alternative to this outcome.
In periods of 'fiscal dominance,' where government debt and deficits are high, a central bank's independence inevitably erodes. Its primary function shifts from controlling inflation to ensuring the government can finance its spending, often through financial repression like yield curve control.
No political leader, whether in a democracy or autocracy, will accept the short-term blame for an economic contraction. The path of least resistance is always to print money and hand out checks, even though it exacerbates the long-term problem.
High debt and deficits limit policymakers' options. Central banks may face pressure to absorb government debt issuance, which conflicts with the goal of raising interest rates to curb inflation, leading to a new era of "fiscal dominance."
