From Central Bank to Treasury: The Rise of Fiscal Dominance

Macro Observations · Part 6. We've covered liquidity, interest rates, the dollar, and inflation. This one unpacks a deep current flowing underneath them all, one that's increasingly becoming the protagonist: fiscal policy. When government debt grows large enough to dominate the macro environment, we enter a new world called fiscal dominance.

011. The Changing of the Guard: From Central Bank to Treasury

For the past forty years, the star of macro has been the central bank.

Starting in the 1980s, when Volcker tamed inflation with brutal rate hikes, monetary policy (the central bank's interest rates and balance sheet) became the main tool for managing the economy. Every investor's gaze was fixed on the Fed—every FOMC meeting, every word from the chair, moved global markets. This was an era of monetary dominance: the central bank was the visible hand, and fiscal policy (government revenue and spending) played a supporting role.

But that structure is undergoing a profound shift—the protagonist is quietly switching from the central bank that prints money to the Treasury that borrows it. This new regime has a name: fiscal dominance.

Fiscal dominance means that when government debt and deficits become large enough, monetary policy loses its freedom—it gets 'kidnapped' by fiscal needs. The central bank must consider: 'Will raising rates make the government's debt burden unsustainable?' In other words: It is no longer the central bank that calls the shots; instead, the massive pile of government debt puts a straitjacket on the central bank. This is a fundamental transfer of power, and it is quietly rewriting all the rules of the macro game.

To understand how this happens, let's look at the state of U.S. debt.

022. The State of Debt: A Structural, Peacetime Deficit

The U.S. fiscal picture has several notable structural features (I'll use directional descriptions, not get bogged down in shifting numbers):

First, debt is at historically high levels. The U.S. government debt-to-GDP ratio is at levels not seen since WWII. That alone is not news, but the following points make it more serious.

Second, the deficit is 'structural', not 'cyclical'. In the past, large fiscal deficits typically appeared during crises or recessions (government spending to rescue the economy) and then narrowed once the crisis passed. But the current pattern is that even in good times—when the economy is strong and there is no crisis—the deficit remains large. This means the deficit is no longer a temporary emergency measure; it is baked into the fiscal structure. This is a qualitative shift: borrowing has gone from 'rescue' to 'routine'.

Third, interest payments are becoming one of the largest expense items. This is the most dangerous part. When interest rates rise (remember the regime change from the interest rates piece), the interest the government must pay on its massive debt explodes, becoming one of the biggest items in the federal budget. And this plants the seed for a terrifying debt doom loop: high rates → exploding interest payments → wider deficit → more borrowing → debt grows further. Once this loop self-reinforces, the fiscal position becomes increasingly passive.

Combine these three—high debt + structural deficit + ballooning interest payments—and you understand why 'fiscal dominance' is not alarmist: when debt is this large and self-expanding in this way, monetary policy can no longer ignore it. When the central bank raises rates to fight inflation, it must weigh: 'Will this push the government's interest burden to unsustainable levels?' The fiscal tail begins to wag the monetary dog.

033. How Fiscal Dominance Changes the Rules: Inflation, Not Default

The deepest implication of fiscal dominance is that it changes the answer to the question, 'What happens when the debt becomes unpayable?' And that answer reshapes interest rates, inflation, and asset prices.

Imagine government debt so large that it can barely be 'paid back normally'. Historically, there are usually three ways out:

1. Default: Simply refuse to pay. But for a sovereign that can print its own money and whose debt is denominated in its own currency (especially the U.S.), outright default is almost unthinkable—it would destroy the entire system's credit. So this path is essentially ruled out.
2. Austerity (tighten belts): Dramatically cut spending and raise taxes to pay down the debt. But this is politically extremely painful and hard to sustain.
3. Inflating it away: This is the historically most common path—allow inflation to be moderately and persistently higher than interest rates, using 'shrinking money' to dilute the real value of the debt. The nominal amount of debt stays the same, but because of inflation, its real purchasing power is quietly eroded. This is an implicit 'inflation tax' levied on all holders of money.

History repeatedly shows that when debt becomes too large to repay, sovereigns most often take the third path—using inflation to dilute the debt. This leads to a key change in the rules under fiscal dominance: it creates a structural bias toward 'tolerating or even needing inflation'.

Specifically, under fiscal dominance, policy tends to favor financial repression—artificially keeping interest rates below inflation, producing negative real interest rates. Under negative real rates, holders of cash and bonds see their purchasing power slowly eroded, while the government's debt burden is gradually relieved. This is a quiet wealth transfer: from savers (those holding cash and bonds) to debtors (the biggest debtor being the government itself).

This fits neatly with previous pieces: fiscal dominance provides the deep engine for a higher inflation center (the previous piece); and it constrains interest rates to be 'managed' at some level (real rates suppressed, i.e., financial repression). Fiscal policy is the hand beneath interest rates and inflation.

044. How This Deep Current Supports Hard Assets

Once you understand fiscal dominance and its tendency toward 'inflation resolution + financial repression', you grasp a key asset logic of this era—why gold and real/hard assets have a structural, underlying support.

The logic is straightforward: if policy is structurally biased toward 'slowly devaluing money to dilute debt' (financial repression, negative real rates), then holding money that will be diluted (cash, long-term bonds) is a losing proposition over the long run; while holding scarce hard assets that cannot be printed is a hedge against that devaluation.

This is the core of the debasement trade:

• Gold: Its entire value lies in the fact that no government can print it or dilute it. In an era when governments are inclined to use inflation to erode debt, gold serves as 'the ultimate hedge against the loss of trust in the monetary and fiscal system' (remember my gold piece—gold hedges not inflation itself, but the erosion of confidence in the whole monetary system).
• Real assets, quality equities with pricing power: They also preserve value during currency debasement, because their value is anchored in real things (assets, cash flows), not in money that will be diluted.

So the deep current of fiscal dominance surfaces in a clear asset tilt: Over the long term, it favors things that are 'scarce and can't be printed', and disfavors things that 'will be slowly diluted' (pure cash, long-term nominal bonds). This is not a short-term trading signal; it is a structural framework for understanding 'why gold and hard assets have underlying support in this era'.

055. But Don't Bet on the Timing of a Debt Crisis

After all this talk about fiscal severity, I must give the most important discipline—recognize the structure of fiscal dominance, but never bet on the precise timing of a debt crisis.

This is a trap where countless smart people have fallen. 'U.S. debt is unsustainable; a crisis is coming'—this argument has been made for decades. And over those decades, almost everyone who bet on a U.S. Treasury crash has lost badly. Why? Because the U.S. has a huge buffer that no other country has—the reserve currency status of the dollar (remember the 'exorbitant privilege' from the dollar piece). It can borrow in its own currency, which the whole world needs, giving it a 'runway' far longer than any normal country's. Debt can persist in a 'seemingly unsustainable' state for far longer than anyone imagines.

That is the dual lesson from This Time Is Different (Reinhart and Rogoff, who studied sovereign debt crises):

• On one hand, don't naively assume 'the U.S. will be fine'—history shows that many former hegemons declined due to debt and currency abuse, and no one has permanent immunity. The structural risk is real.
• On the other hand, be even more wary of the temptation that 'a crisis is imminent'—the timing of a debt crisis is extremely hard to predict; it may continue to operate smoothly for another decade or two after you predict it. Betting on the timing of a crisis is a game that loses far more often than it wins.

So my attitude toward fiscal dominance is consistent with the entire series—position, not predict. I use it to understand the structural tendencies of this era (financial repression, inflation resolution, underlying support for hard assets), and adjust my long-term allocation accordingly (give a place to gold/hard assets; don't hold large long-term positions in assets that will be diluted). But I never use it to bet on 'which year the debt crisis will break out', never short Treasuries betting on a crash. Understand the structure, enjoy the long-term allocation insights it provides; but give up on predicting crisis timing—because that is where even the smartest people repeatedly trip up.

066. Final Thoughts

Fiscal dominance is the deepest and most easily overlooked macro current of this era.

It marks a changing of the guard—from the printing-press hand of the central bank, which everyone watches, to the quieter but more powerful borrowing hand of the Treasury. When government debt becomes large enough to kidnap monetary policy in return, the rules of the game are silently rewritten: interest rates are suppressed by financial repression, inflation is tolerated or even needed, and the purchasing power of savers is quietly transferred to dilute government debt.

This deep current explains many seemingly disconnected phenomena of this era—why real rates are suppressed, why the inflation center is higher, why gold and hard assets have underlying bids. It is the hand beneath interest rates, inflation, and the dollar.

But it is also the variable that most tests discipline. Because it most easily tempts people to do one stupid thing: bet that 'a debt crisis is about to erupt.' And history shows again and again that, on the long runway of a reserve currency, such bets often ruin you even while being 'right'. So for this, I stick to the iron rule of the entire series: Recognize the structure, tilt long-term allocation accordingly; but give up on predicting crisis timing, and leave that humility to those who are smarter than me yet still repeatedly get the timing wrong on debt.

If only one sentence remains—

The macro protagonist is shifting from the central bank that prints money to the Treasury that borrows it. This deep current tends to resolve debt via inflation and suppress interest rates via financial repression—providing underlying support for gold and hard assets. Understand this structure, but never bet on the timing of a debt crisis: on a reserve currency's runway, 'unsustainable' can last far longer than anyone imagines.

Next up, the finale of this macro series—we combine the five coordinates (liquidity, interest rates, the dollar, inflation, fiscal) to do what the preface promised: not predict the future, but make a complete assessment of 'where I stand right now'.
