In a world of high debt and low organic growth (from demographics and productivity), the only viable path for governments is to ensure nominal GDP grows. This will likely be achieved through inflationary policies, making official low-inflation forecasts unreliable over the long term.

Traditional analysis links real GDP growth to corporate profits. However, in an inflationary period, strong nominal growth can flow directly to revenues and boost profits even if real output contracts, especially if wage growth lags. This makes nominal figures a better indicator for equity markets.
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.
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.
Due to massive government debt, the Fed's tools work paradoxically. Raising rates increases the deficit via higher interest payments, which is stimulative. Cutting rates is also inherently stimulative. The Fed is no longer controlling inflation but merely choosing the path through which it occurs.
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.
Governments with massive debt cannot afford to keep interest rates high, as refinancing becomes prohibitively expensive. This forces central banks to lower rates and print money, even when it fuels asset bubbles. The only exits are an unprecedented productivity boom (like from AI) or a devastating economic collapse.
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.
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."
The Fed is cutting rates despite strong growth and inflation, signaling a new policy goal: generating nominal GDP growth to de-lever the government's massive, wartime-level debt. This prioritizes servicing government debt over traditional inflation and employment mandates, effectively creating a third mandate.
