When to roll a Treasury ladder.
A T-bill ladder is the safest cash strategy in retail finance. It is not the most thoughtful one. The roll decision is where the yield is won or lost.
A free yield decision most retail leaves on the table.
The standard retail approach to a Treasury ladder is to roll every maturity into the same tenor. In a flat or inverted curve, that costs 50 to 120 basis points relative to a curve-aware roll. The Fed publishes the inputs needed to make the decision daily; most retail simply does not look.
The nine indicators
The nine macro indicators behind every roll.
Each is updated by the Fed, Treasury, or futures market on a known schedule. The discipline is to consult them before the roll, not after.
10y minus 3m yield-curve slope
Sign and magnitude
An inverted curve (negative slope) rewards short tenors. A normal curve rewards extension. The slope tells you which side of the trade is paying.
Fed funds futures implied path 6 months out
Bps of implied moves
If the futures curve prices 75 bps of cuts in 6 months, locking in 6-month bills now beats rolling 4-week paper through the cuts. The futures market is the consensus.
FOMC dot plot median for the next two meetings
Dots vs current rate
The dot plot is committee guidance. Compare the median dot to current spot funds. The gap is the directional bias for short tenors.
5y5y forward inflation breakeven
Threshold: trend up vs down
Trending-up breakevens favor TIPS over nominal bills. Trending-down breakevens favor nominal. The breakeven is the inflation premium baked into the curve.
MOVE index level vs 90-day average
Threshold: > 1 std dev
High MOVE means high implied rate volatility. In high-volatility regimes, the term premium widens and longer tenors become cheaper relative to expected path.
Treasury auction tail or stop-through pattern
Pattern: 3 of last 5 auctions
Persistent auction tails (yield above the when-issued) signal weak demand and rising new-issue yields. The trend predicts the next auction's outcome.
Treasury issuance calendar — net coupon supply
Threshold: > $100B/quarter
Heavy net coupon issuance pressures the long end. When the calendar is heavy, short bills are relatively favored.
Repo rate vs IORB
Spread direction
Persistent repo-IORB spread compression signals plumbing stress. Short bills remain anchored; longer tenors get cheaper as plumbing risk rises.
DXY (dollar index) trend
Direction over 90 days
A weakening dollar tends to attract foreign demand for Treasuries. A strengthening dollar reduces foreign bid. The marginal flow shows up in the 5–10y belly.
Why the roll is the most important decision in a ladder
A Treasury bill ladder built once and rolled mechanically is a default cash strategy. It outperforms a savings account by 100 to 300 basis points in most rate regimes, and it is intrinsically safe. The decision that distinguishes a good ladder from a great one is the roll: when a 4-week bill matures, does the cash go back into another 4-week, into a 13-week, into a 26-week, or into a 52-week note? The answer depends on the curve shape and the implied path, and it changes from quarter to quarter.
Most retail platforms default to rolling into the same tenor. This is convenient and almost always wrong. In an inverted curve, the highest-yielding cash is the shortest tenor; in a normal curve, modest extension out to 13–26 weeks captures meaningful additional yield without taking material duration risk.
The curve shape is the first signal, not the last
The 10-year minus 3-month spread is the single most-watched curve summary statistic. When it is positive and rising, the curve is normalizing — extension out the curve is paying. When it is inverted, the front end is paying. The signal is direct and updated daily on the Fed's H.15 release.
The discipline is to look. Most retail rolls do not look. A ladder rolled mechanically through a curve normalization captures the same yield as a savings account; a ladder rolled with attention to the slope captures 75–150 bps more on average.
Fed funds futures — the consensus path
The Fed funds futures curve prices the market's expectation of the path of the federal funds rate. If the futures curve prices 50 basis points of cuts over the next six months, locking in a 6-month bill at the current yield captures the existing rate before it falls. If the futures curve prices 25 bps of hikes, rolling short and waiting for the higher rates to arrive is the better choice.
The CME FedWatch tool publishes the implied probabilities for free. Reading it takes one minute. Acting on it captures 30–80 bps of additional yield per year in regimes with directional rate movements.
When inflation breakevens flip — TIPS vs nominal
TIPS pay the real yield plus realized CPI. Nominals pay a fixed nominal yield. The choice between them is determined by future inflation: if inflation runs above the breakeven, TIPS win; below, nominals win. The 5y5y forward breakeven is the cleanest summary of long-run expectations.
For a cash ladder, the relevant tenors are 5-year and shorter. Short TIPS (1–3y) carry the same inflation indexation but with less duration. When 2y breakevens trend up persistently, short TIPS deserve a place in the ladder alongside nominal bills.
MOVE — the rate volatility regime
The MOVE index is the bond market's VIX. High MOVE — above one standard deviation of the trailing 90-day average — signals an unstable rate regime. In those regimes, the term premium widens; longer tenors become cheaper relative to the expected path because the market demands compensation for uncertainty. A patient ladder roller can capture that premium by extending modestly into the 13–26 week range.
Low MOVE means the term premium is compressed. In low-MOVE regimes, extension out the curve pays less, and the case for short bills is stronger.
Building and maintaining the ladder
The mechanics are simple. Open an account at TreasuryDirect, Fidelity, or Schwab. Buy 4-week, 8-week, 13-week, 26-week, and 52-week bills in equal amounts. As each matures, run the nine-indicator screen and choose the next tenor based on the regime. The expected effort is approximately 15 minutes per month; the expected yield improvement over a mechanical ladder is 50–120 basis points per year.
The strategy is self-correcting. The nine indicators move together in regimes; the screen tends to favor the same tenor across multiple maturities in a stable regime and to rotate the entire ladder when the regime shifts.

Common questions
Questions.
What's the best platform for a T-bill ladder?
TreasuryDirect (no fees, government-direct) for purists, Fidelity or Schwab (auto-roll, no commission, slightly better liquidity for selling early) for most retail. The choice is operational, not financial; yields are identical.
Should I prefer T-bills or money-market funds?
Direct T-bills generally win on after-tax basis (state tax exemption) and on counterparty risk. Money-market funds win on liquidity and convenience. For balances above $25,000, the after-tax case for direct bills is usually decisive.
How long should the ladder be?
Three to six months for an emergency fund. Six to eighteen months for working cash. Above eighteen months, the cash should be deployed elsewhere — the ladder is no longer the highest-and-best use.
What about brokered CDs?
Brokered CDs typically yield 10–30 bps less than T-bills of equivalent tenor and carry FDIC limits. The case for brokered CDs is weak unless the investor is at the edge of the FDIC limit on the bank side.
Are TIPS worth it for a short ladder?
Sometimes. Short TIPS carry inflation protection at a real-yield cost. When 2-year breakevens are above 2.5% and trending up, short TIPS deserve a slice of the ladder. Otherwise, nominal bills are simpler.
How do I buy at auction?
TreasuryDirect places non-competitive bids automatically at the auction yield. Brokerage platforms aggregate retail bids and submit on the participant's behalf. Both result in the same yield; the auction calendar publishes dates monthly.
