T-Bills - The OG Stablecoin Farm

9 min read8 min read

U.S. Treasury Bills are DeFi's grandfather—the original risk-free yield farm that every stablecoin desperately tries to replicate. With $26 trillion in total Treasury debt outstanding (that's 173x larger than all stablecoin market caps combined), T-Bills are the collateral that backs the entire global financial system. They're USDC if USDC was actually decentralized, liquid, and accepted everywhere as money.

The Treasury Market: Bigger Than Crypto Will Ever Be

The U.S. Treasury market is the deepest, most liquid market in human history:

  • Daily Volume: $650 billion (vs. all crypto: $100 billion)
  • Outstanding Debt: $26 trillion (vs. all crypto mcap: $2.5 trillion)
  • Number of Holders: Every central bank, commercial bank, pension fund, and boomer's 401(k)
  • Yield: Currently 5.0-5.5% (better than 90% of DeFi farms)

The Product Line: Duration-Based Yield Curves

Treasury Type Duration Current Yield DeFi Equivalent
T-Bills 4-52 weeks 5.25-5.40% Fixed-term staking
T-Notes 2-10 years 4.20-4.60% Bonding curves
T-Bonds 20-30 years 4.40-4.70% Perpetual vaults
TIPS 5-30 years 2.20% + inflation Inflation-protected pools
FRNs 2 years Floating rate Variable APY vaults

The Primary Dealers: Permissioned Market Makers

Only 24 banks have the privilege of buying directly from the Treasury—the Primary Dealers. They're like having exclusive access to token launches before they hit Uniswap:

The Cartel Members

  • JPMorgan: Also owns Chase, also too big to fail
  • Goldman Sachs: The vampire squid of Treasury trading
  • Citadel Securities: Yes, that Citadel (Ken Griffin's money printer)
  • Deutsche Bank: Somehow still a primary dealer despite everything

These dealers MUST bid at every Treasury auction, providing guaranteed liquidity. In exchange, they get:

  • First access to new issuance (like whitelist minting)
  • Direct repo access with the Fed (infinite leverage glitch)
  • Information advantage from flow (legal front-running)

The Auction Mechanism: Dutch Auctions Before They Were Cool

Treasury auctions are the OG token launches, happening on a predictable schedule:

  1. Announcement: Treasury says "we're minting $50 billion in 3-month bills"
  2. Bidding: Primary dealers submit competitive bids (price and quantity)
  3. Allocation: Highest bidders win, everyone pays the same clearing price
  4. Settlement: T+1 (yes, it takes a day to send numbers to accounts)

It's like a Fair Launch Auction (FLA) except:

  • You need a banking license to participate
  • Minimum bid is $100 million
  • Retail gets whatever crumbs are left

The Yield: Where "Risk-Free Rate" Comes From

T-Bills are considered "risk-free" because the U.S. has the money printer and nuclear weapons. This creates the baseline for all other yields:

The Pecking Order of Yields

T-Bills (5.25%) 
    ↓ +10 bps
Fed Funds (5.35%)
    ↓ +15 bps  
SOFR (5.30%)
    ↓ +50 bps
Investment Grade Corporate (5.80%)
    ↓ +200 bps
High Yield / Junk (7.50%)
    ↓ +500 bps
DeFi Stablecoin Yields (10%+)

Every yield in TradFi is "T-Bills + risk premium." It's the Universal Basic Yield that everything else builds on.

The Repo Market: Leveraging T-Bills for Infinite Money

The repurchase agreement (repo) market lets you stake T-Bills for cash, creating leverage out of thin air:

How Repo Actually Works

  1. You own: $100 million in T-Bills
  2. You need: Cash for trading
  3. The trade:
    • Sell T-Bills for $100M cash today
    • Agree to buy back tomorrow for $100.014M
    • Overnight rate: 5.3% annualized
  4. The leverage: Use the $100M to buy more T-Bills, repo those, repeat

This is how hedge funds achieve 10:1 leverage on "risk-free" assets. It's recursive borrowing using the same collateral—exactly like Abracadabra's degenbox strategy, except blessed by regulators.

The 2019 Repo Crisis: When the Stablecoin Depegged

In September 2019, repo rates spiked to 10% (from 2%) overnight. The plumbing of global finance broke because:

  • Banks hoarded reserves for quarter-end reporting
  • Treasury issued too many T-Bills
  • Corporate tax payments drained liquidity

The Fed had to emergency inject $75 billion daily to prevent systemwide collapse. Imagine if USDC depegged to $0.90 because Circle forgot to have enough cash on hand. That's what happened, but with the entire financial system.

STRIPS: Composable Yield Farming Before DeFi

Treasury STRIPS (Separate Trading of Registered Interest and Principal Securities) are DeFi composability in 1985:

The Mechanism

Take a 10-year Treasury paying 4.5% annually:

  1. Strip the coupons: Separate each interest payment
  2. Sell components:
    • 20 semi-annual coupon payments (each a zero-coupon bond)
    • 1 principal payment at maturity
  3. Create products: Package different strips for different yields

It's like splitting an LP position into separate principal and yield tokens. Pendle didn't invent yield tokenization—Treasury dealers did it 40 years ago.

The Debt Ceiling: Congress's Infinite Mint Governance Attack

The debt ceiling is Congress's ability to turn off the Treasury's mint function, holding the global economy hostage for political points:

The Recurring Drama

  1. Treasury approaches limit: "We need to mint more tokens"
  2. Congress grandstands: "No more printing!" (they will print more)
  3. X-Date approaches: Treasury runs out of money in T-30 days
  4. Market panic: T-Bill yields spike, stocks dump
  5. Last-minute deal: Congress raises ceiling, nothing changes
  6. Repeat: Every 1-2 years since 1917

Extraordinary Measures: The Treasury's Flashloan Hacks

When hitting the debt ceiling, Treasury uses "extraordinary measures":

  • Suspend reinvestment: Stop rolling G Fund (government pension)
  • Raid trust funds: "Borrow" from Social Security
  • Accounting gimmicks: Reclassify expenses as "investments"
  • Mint the coin: Theoretical $1 trillion platinum coin deposit at Fed

Yes, the "mint the coin" thing is real—it's a legal loophole where Treasury could mint a $1 trillion coin, deposit it at the Fed, and bypass the debt ceiling entirely. It's the ultimate infinite mint exploit that's technically legal but would probably crash the dollar.

Foreign Holdings: The International Bag Holders

Foreign central banks hold $8 trillion in Treasuries—they're exit liquidity for America's deficit spending:

The Biggest Bag Holders

Country Holdings Why They Hold
Japan $1.1 trillion Weaken yen, export competitiveness
China $770 billion Dollar reserves, trade surplus recycling
UK $690 billion London eurodollar banking
Luxembourg $370 billion Tax haven flow through
Switzerland $290 billion SNB currency manipulation

China dumping Treasuries is the TradFi equivalent of a whale market-selling their entire position. It would spike yields, crash bond prices, and potentially end dollar hegemony. That's why it's the "nuclear option" in financial warfare.

The TreasuryDirect Scam: Retail's Fake DeFi Access

TreasuryDirect is the government's hilariously bad attempt at retail access:

  • UI/UX: Designed in 1995, never updated
  • Authentication: Requires physical keyboard (virtual keyboards disabled)
  • Limits: $10 million per auction (whales need not apply)
  • Settlement: Bank account only (no crypto)
  • Customer Service: Phone only, 9-5 Eastern

It's like if Uniswap required KYC, had a $10M trade limit, and only worked on Internet Explorer.

The Inverted Yield Curve: The Recession Speedrun Timer

When short-term yields exceed long-term yields, the yield curve inverts—the bond market's recession prediction that's been right 8 out of 8 times:

Current Inversion (2024)

  • 3-month: 5.40%
  • 10-year: 4.30%
  • Spread: -110 bps (deeply inverted)

This means the market expects rates to drop (recession incoming). It's like when funding rates go deeply negative—someone knows something.

Why Inversions Predict Recessions

  1. Banks stop lending: Can't profit from borrowing short, lending long
  2. Credit contracts: Loan creation slows
  3. Economy slows: Less credit = less growth
  4. Fed cuts rates: Tries to restart lending
  5. Recession: Usually within 12-18 months of inversion

Operation Twist: The Original Yield Curve Control

The Fed doesn't just buy Treasuries—they manipulate specific parts of the curve:

Historical Yield Curve Manipulations

  • Operation Twist (1961): Sell short-term, buy long-term (flatten curve)
  • Operation Twist 2.0 (2011): Same thing, bigger size
  • Yield Curve Control (2020): Considered capping 10-year at 0.5%
  • QE Maturity Extension: Buy longest duration for maximum impact

It's like Curve Wars but for government bonds. The Fed literally votes with printed money to set the interest rate curve shape.

T-Bills as Collateral: The Real Stablecoin Backing

T-Bills back everything in TradFi:

  • Stablecoins: USDC/USDT hold mostly T-Bills
  • Money Market Funds: 80% T-Bills and repo
  • Bank Reserves: Can be swapped for T-Bills at Fed
  • Derivatives Margin: CME accepts T-Bills as collateral
  • International Trade: T-Bills used for settlement

The Collateral Multiplier Effect

One T-Bill can be:

  1. Owned by a pension fund
  2. Lent to a hedge fund via repo
  3. Re-lent to a bank via repo
  4. Posted as derivative margin
  5. Counted as regulatory capital

The same T-Bill is simultaneously collateral in 5+ places. It's rehypothecation that makes DeFi flash loans look conservative.

The QE Trade: Front-Running the Fed

When the Fed does QE, they announce exactly what they're buying. Hedge funds front-run by:

  1. Buy bonds the Fed will buy
  2. Wait for Fed bid to push prices up
  3. Sell to Fed at inflated prices
  4. Profit: Risk-free gains from front-running

It's like if Ethereum Foundation announced "we're buying $1B of UNI next week." Every MEV bot would buy first. Except in TradFi, it's legal and called "market making."

T-Bill ETFs: Liquidity Pools for Boomers

ETFs like SHY and SGOV are basically T-Bill liquidity pools:

  • AUM: $50+ billion each
  • Fees: 0.05-0.15% annually
  • Liquidity: Trade like stocks, settle T+2
  • Yield: T-Bill rate minus fees

It's wrapping T-Bills in an ERC-20 token, charging fees, and calling it innovation. BlackRock makes billions from this 0.05% fee on money that would earn the same yield directly.

The Petrodollar System: Forced Protocol Adoption

The petrodollar system forces oil-exporting countries to:

  1. Price oil in dollars (protocol requirement)
  2. Accumulate dollar reserves (from oil sales)
  3. Buy T-Bills (recycle dollars back to U.S.)
  4. Depend on dollar system (locked in)

It's like requiring all DeFi transactions to use USDC, then making USDC only backed by your protocol's governance token. Saudi Arabia alone holds $140 billion in T-Bills because they have no choice.

Conclusion: The Stablecoin That Rules Them All

T-Bills are the ultimate stablecoin—backed by the full faith, credit, and military of the United States. They're:

  • Infinitely mintable (debt ceiling theater aside)
  • Globally accepted (reserve currency status)
  • "Risk-free" (nuclear weapons ensure repayment)
  • Yield-bearing (5%+ for doing nothing)
  • Composable (repo, STRIPS, ETFs)

Every stablecoin is just a wrapped T-Bill with extra steps. USDC? It's 80% T-Bills. USDT? Mostly T-Bills and repo. DAI? Increasingly backed by USDC (which is T-Bills).

The entire stablecoin industry is just repackaging T-Bills with blockchain settlement. It's the biggest TVL farm in history, and the U.S. Treasury is the yield farmer, extracting value from the entire planet through "risk-free" debt that everyone needs as collateral.

The joke is that DeFi is trying to disintermediate finance, but ends up holding the same T-Bills as collateral, just with more steps and higher fees. We haven't escaped TradFi—we've just built a more expensive wrapper around it.
