The Gravity

The Federal Reserve has cut interest rates 175 basis points since September 2024. From 5.25% to 3.50%. The most aggressive easing cycle since the pandemic.

The 30-year Treasury yield has risen 31 basis points over the same period.

+31bp

30-year yield change during 175bp of Fed rate cuts

The Fed controls the overnight rate. It does not control the 30-year rate. And the 30-year rate is what prices your mortgage, your corporate bond, your pension obligation. The gap between what the Fed can do and what the market does is called fiscal dominance — the point at which government borrowing overwhelms monetary policy.

We have arrived.

I. The Yield Curve Split

Maturity	Current	1 Year Ago	Change	Follows Fed?
3-Month (^IRX)	3.60%	4.19%	-59bp	Yes — tracks Fed cuts
5-Year (^FVX)	3.87%	4.10%	-22bp	Partially
10-Year (^TNX)	4.29%	4.31%	-2bp	Barely
30-Year (^TYX)	4.91%	4.60%	+31bp	No — defies Fed entirely

The yield curve has split in half. The front end (3mo) dutifully followed the Fed down by 59bp. The long end (30Y) went the opposite direction, rising 31bp. The spread between 3mo and 30Y has widened from +41bp to +131bp — a 90bp steepening in one year.

Translation: The market trusts the Fed to set the overnight rate. It does NOT trust the Fed to solve the fiscal problem. The long end is repricing for a world where the government borrows $1.9 trillion per year, every year, into a market that no longer has a $2.5 trillion RRP buffer to absorb the supply.

II. The $1 Trillion Interest Bill

Interest Payments (FY2026)

$1.0T

+7% from FY2025

National Defense

$1.4T

Interest nearly equals defense

Interest as % GDP

3.3%

New all-time record (beats 1991)

In Q1 FY2026 alone (October-December), the government spent $270.3 billion on interest — exceeding the pace of defense spending. For the full fiscal year, interest payments are projected at $1.0 trillion. Over the next decade, they'll double to $2.1 trillion per year. Total interest over the next 10 years: $16.2 trillion.

Interest payments are now the fastest-growing budget category. Not Social Security. Not Medicare. Not defense. Interest.

The arithmetic trap:

National debt: $38.5 trillion

Average interest rate on outstanding debt: ~2.6% (weighted average of old cheap debt + new expensive debt)

As old 1-2% debt matures and rolls into 4-5% debt, the average rate rises mechanically.

Every 100bp increase in average rate = $385 billion/year in additional interest.

At the current rolling rate, even WITHOUT new borrowing, interest payments grow by $50-80B/year just from maturing cheap debt being replaced by expensive debt. The debt is repricing itself higher regardless of what the Fed does.

III. The Feedback Loop

  Higher Yields
  
↓
  
Higher Interest Costs ($1T+)
  
↓
  
Larger Deficit ($1.9T/year)
  
↓
  
More Treasury Issuance ($574B in Q1 alone)
  
↓
  
More Supply Overwhelms Demand
  
↓
  
Higher Yields
  
  This loop is self-reinforcing. Each cycle raises the floor for interest costs, which widens the deficit, which requires more issuance, which pushes yields higher. The loop has no natural exit.

The CBO projects the deficit at $1.9 trillion (5.8% of GDP) for FY2026. This is a peacetime, non-recession deficit. In 2007, the deficit was 1.1% of GDP. In 2019, it was 4.6%. We're running a deficit wider than anything outside of COVID and the GFC — and the economy isn't in crisis (officially).

IV. DOGE: The Card That Wasn't

The Department of Government Efficiency was supposed to be Trump's fiscal card. $2 trillion in cuts. A lean government. The deficit solved.

DOGE Target (Original)

$2.0T

Musk, November 2024

DOGE Target (Revised)

$150B

Musk, March 2026

Actual Impact

+$150B

Spending INCREASED (WSJ)

The inversion: DOGE was the government's optionality card — the promise that spending could be cut without touching Social Security or Medicare (64% of the budget). The card has been played and produced negative results. Government spending has increased by approximately $150 billion since Trump returned to office, according to the Wall Street Journal. DOGE's cuts may have cost $135 billion in paid leave and lost productivity (CBS/analysis).

The original $2T target → revised to $1T → revised to $500B → revised to $150B → actual impact: spending went UP. This is card depletion at its most visible. The fiscal optionality has been consumed. There is no next card.

64% of spending is Social Security, Medicare, and health programs. Trump vowed not to touch them. Defense is 13% and politically untouchable with oil at $99 and an ongoing military operation. That leaves 23% of the budget for "everything else" — and DOGE already ransacked that slice.

V. The Bessent Strategy: Shift to Bills

Treasury Secretary Scott Bessent adopted a strategy: keep long-term auction sizes unchanged "for several quarters" and fund the deficit with short-term bills instead. This relieves long-end supply pressure temporarily.

Recent Auction	Date	Yield	Bid/Cover	Indirect	Direct
30-Year Bond	Mar 12	4.871%	2.45x	63.3%	27.2%
10-Year Note	Mar 11	4.217%	2.45x	74.3%	12.8%
3-Year Note	Mar 10	3.579%	2.55x	59.6%	20.6%

The 30Y auction shows the strain: indirect bidders (foreign CBs) at 63.3% vs 74.3% on the 10Y. The voluntary buyers are stepping back from duration. Direct bid at 27.2% is strong — but that's domestic buyers stepping in to fill the foreign gap. Eventually, the domestic balance sheet runs out too.

The Bessent trade-off:

Shifting issuance to bills (short-term) shortens the average maturity of the federal debt. This means MORE of the $38.5T debt reprices at current rates faster. If rates stay high or rise, the interest bill grows faster than it would with long-term lock-in.

It's the same mistake homeowners made in 2006: choosing the adjustable-rate mortgage because the monthly payment was lower TODAY. When rates moved, the payment exploded.

Bill supply: B/C ratios of 2.77-3.19 suggest strong demand now. But this is partly because the Fed is buying $40B/month in bills (RMPs from Report #91). When RMPs end in April, who replaces the Fed as the marginal bill buyer?

VI. The Long Bond Massacre

ETF	Exposure	1mo	3mo	6mo	1yr
SHY	1-3 Year	-0.4%	-0.4%	-0.5%	+0.1%
IEF	7-10 Year	-0.7%	-0.6%	-1.4%	+0.8%
TLT	20+ Year	-1.7%	-0.9%	-3.8%	-4.5%
ZROZ	25+ Year Zero-Coupon	-2.0%	-2.0%	-7.1%	-11.0%
TMF	3x Long 20+ Year	-5.0%	-3.5%	-12.6%	-17.5%
TBT	2x Short 20+ Year	+3.4%	+0.7%	+5.3%	+3.9%

Duration is death. Every duration bucket has lost money over 6 months. The only winning bond trade was SHORTING long bonds (TBT +5.3% in 6mo). The further out you go on the curve, the worse the carnage: ZROZ (zero-coupon 25+ year) lost 11% in a year. TMF (3x leveraged) lost 17.5%.

This is the market's verdict on fiscal dominance: nobody wants to lock in long-term rates when the government's borrowing trajectory makes rate normalization impossible.

VII. The Spec Position: $3 Trillion Short

Date	5Y Treasury Spec Net	Weekly Change	Open Interest
Mar 10	-3,085,919	+18,024	6,756,942
Mar 3	-3,103,943	-56,381	6,769,879
Feb 24	-3,047,562	+63,480	7,376,192
Feb 17	-3,111,042	+8,710	7,431,251

Specs are short 3.1 million contracts on the 5-year Treasury. At $100K notional per contract, that's $310 billion in short bets against intermediate-duration Treasuries. The position has barely moved in a month — the shorts aren't covering because the fiscal arithmetic supports their thesis.

Combined with the 10Y position from Report #89 (-1.88M contracts), the speculative community has over $500 billion in notional shorts against government bonds. This is not a trading position. It's a structural thesis: the government can't fund itself without pushing yields higher.

VIII. The Rate Cut Paradox

The deepest inversion in this entire series:

The Fed cut rates 175bp to ease financial conditions. This achieved three things:

1. Enabled cheaper Treasury bill issuance — the government shifted to bills, saving short-term interest costs.

2. Created fiscal space for continued deficit spending — lower bill rates meant the $1.9T deficit was "affordable" in the short term.

3. Pushed long-term yields HIGHER — because the market realized that cheaper short-term funding + continued deficits = MORE issuance over time = more supply at the long end = higher long-term yields.

The rate cuts funded the borrowing that raised the yields that the rate cuts were supposed to lower.

This is fiscal dominance. The Fed can set the price of overnight money. But the long end of the curve — the rate that matters for mortgages, corporate bonds, and pension discounting — is set by the government's insatiable appetite for debt. The tail (Treasury supply) is wagging the dog (the yield curve).

IX. What Would Fix This?

Five paths out of fiscal dominance. None are easy:

Path	Probability	Consequence
Reduce deficit to <3% GDP	Very low	Requires $700B+ in cuts or tax hikes. Political suicide.
Inflate the debt away	Moderate	5%+ inflation for years. Erodes purchasing power. Already partially happening.
Financial repression	Moderate	Force institutions to buy Treasuries (pension mandates, bank regs). Suppresses long yields artificially.
GDP growth exceeds debt growth	Low in current environment	Need sustained 3%+ real growth. GDP revised to 0.7%.
Foreign buyers return in force	Low	Requires dollar confidence + geopolitical stability. Oil at $99 and Hormuz closed.

The most likely path is a combination of inflation and financial repression — the government slowly forces buyers to accept negative real returns (yield minus inflation) while maintaining the nominal facade of "4% bonds." This is already happening: 30Y at 4.91% with inflation at 3.0% = real yield of 1.91%. In the 1970s, real yields went negative for a decade. The market is pricing a path toward that outcome.

X. Implications for Wednesday

FOMC March 18 is 72 hours away. The dot plot is the mechanism through which the Fed communicates its rate path. But fiscal dominance means the dot plot is increasingly irrelevant for long-term yields.

The Powell paradox:

If Powell signals MORE cuts (dovish): short-term rates fall → Treasury shifts MORE issuance to bills → long-end supply pressure temporarily eases → but deficit grows → more issuance needed → long end eventually rises anyway.

If Powell signals FEWER cuts (hawkish): short-term rates stay high → Treasury bill funding costs rise → deficit grows from BOTH higher rates AND structural spending → long end rises.

If Powell signals EMERGENCY action: Fed restarts QE to absorb Treasury supply → temporarily suppresses long yields → but oil at $99 means inflation reignites → credibility destroyed → long yields spike on inflation expectations.

All three paths lead to higher long-term yields. The Fed has no good option because the fiscal problem is upstream of monetary policy. You can't solve a spending problem with an interest rate tool.

"The market trusted the Fed when the Fed was the biggest buyer of bonds. The Fed stopped buying. The Treasury didn't stop selling. The arithmetic is doing the rest."
