The Ladder Math

Start with the number that should be getting more attention than it is.

The thirty year Treasury is yielding better than five percent. The ten year sits near four and two thirds, the two year around four and a quarter, and the Fed funds target has been parked at three and a half to three and three quarters since last year.

Now hold that next to what the Fed did on July 29. It held, nine to three, with three regional presidents dissenting because they wanted to raise rates. The June projections penciled in one quarter point increase before year end. Inflation has run above the two percent target for more than five years, and July came in around three and a half.

Put those together and you get a situation most investors under fifty have never operated in. The long end is paying a real yield that is genuinely positive. The curve has a normal upward slope again. And the risk everyone is positioned for, another cut, is not the risk the committee is actually debating.

For fifteen years the fixed income side of a portfolio was a place you parked money and apologized for. That is over, and most people have not updated the machinery. They still own one bond fund, bought in a different decade, for reasons they could not fully articulate if pressed.

Today we fix that with a ladder. The case for it is not that the yield is better, because it usually is not. The case is structural, and once you see it you cannot unsee it.

A bond fund never matures. A bond does.

That sentence is the entire deep dive. The rest is arithmetic around it.

When you buy an individual Treasury and hold it to maturity, two things are fixed on the day you buy: the interest you will collect, and the date you get your principal back at par. Rates can do whatever they like in between. Your outcome does not change. Price moves are noise on a statement, not events in your life, because you have a contractual claim on a specific number on a specific date.

A bond fund has no such date. It holds a rolling basket, sells positions as they age out of the mandate, and buys new ones. There is no day on which the fund pays you par. There is only the net asset value, which is whatever the market says the basket is worth this morning.

Which means when you need your money, you sell at whatever price exists that day. If rates rose, you sell at a loss. The loss is real, permanent, and realized, not a paper wobble you can wait out, because there is nothing to wait for.

Ask anyone who owned an intermediate bond fund in 2022. The math worked exactly as designed and it still hurt, because duration risk in a fund is not something you can hold your way through. You can hold an individual bond through it. That is the whole difference.

I am not going to pretend a ladder is free. You are trading price risk for reinvestment risk, and that is a real trade rather than a free lunch.

With a fund, your risk is that rates rise and the value drops. With a ladder, your risk is that rates fall and each maturing rung reinvests at a worse yield than the one it replaced. You cannot escape both. You are choosing which one you would rather own.

Here is why the ladder side looks better from where we sit. Reinvestment risk arrives slowly and in pieces, one rung at a time, on a schedule you can see coming. Price risk arrives all at once, on the day you happen to need the money, which is exactly the day you have the least flexibility.

And there is a second asymmetry. A ladder built now locks a real yield across multiple maturities. If the committee actually delivers the increase it has penciled in, your near rungs mature into higher rates and you reinvest upward. If instead the economy rolls over and rates fall, your long rungs are already locked at today's yields and you look brilliant. The structure participates in both directions rather than betting on one.

That is not clever positioning. It is just what happens when you own claims on many different dates instead of one blended average.

A ladder is a set of bonds maturing at regular intervals. Five choices define yours.

One: how long. The length of the ladder should match what the money is actually for. Money you need inside two years does not belong in a ladder at all. Money with no defined date, meaning long term reserves, can run five to ten years. Ten rungs at one year spacing is a reasonable default and covers most situations.

Two: how far apart. Annual spacing is standard and simple. Semiannual gives you liquidity events twice as often at the cost of more positions to manage. Below a hundred thousand dollars, annual. Above it, either works.

Three: how much per rung. Equal weight is the default and it is the right default. Every rung the same size means every year you get the same amount back, which makes the thing predictable, which is the entire point. Resist the urge to overweight the maturity that currently yields most. That is a rate forecast wearing a ladder costume.

Four: what to fill it with. Treasuries for the core, for two reasons I will come back to. Certificates of deposit are fine at short maturities if the yield beats Treasuries after tax. Investment grade corporates add yield and credit risk, and if you use them, ladder across many issuers rather than concentrating, because a default does not care that you had a plan.

Five: where to buy. TreasuryDirect works and costs nothing, but it is government software and a walled garden. A brokerage account is better for most people. The bonds sit alongside everything else, the secondary market gives you every maturity date rather than only auction dates, and most brokers have an auto roll setting that reinvests a maturing bond at the same tenor. That setting is what turns a ladder into a machine instead of a chore.

Here is why I said Treasuries for the core.

Interest on Treasury securities is exempt from state and local income tax. Corporate bond interest, CD interest, and most money market interest is not.

This is not a rounding error if you live somewhere with real state income tax. In a state with a nine or ten percent rate, a Treasury yielding four and a half percent is delivering roughly the same after tax result as a corporate bond yielding close to five, with none of the credit risk. Anyone comparing headline yields across those two without adjusting is comparing the wrong numbers.

The placement rule follows. Taxable bond interest is ordinary income, taxed at your top rate every year whether you spend it or not. If you hold both taxable and tax deferred accounts, the ladder generally belongs in the tax deferred one. Getting the location wrong can cost more than the entire yield difference you spent a weekend optimizing.

One addition worth making, given the specific moment.

Inflation has run above target for more than five years. Three separate Fed presidents dissented last month because they think it is still not handled. Whatever your view, the possibility that inflation stays sticky is not remote, and a nominal ladder has no defense against it. You locked a fixed number. If prices run hotter than expected, that fixed number buys less.

Treasury inflation protected securities solve that directly. The principal adjusts with the consumer price index, so the yield you are quoted is a real yield, on top of whatever inflation does.

Two things before you use them. Buy TIPS individually rather than through a fund if you want the protection to actually work, because the same maturity problem applies and a TIPS fund can lose value in real terms. And hold them in a tax deferred account where possible, because the inflation adjustment to principal is taxable in the year it happens even though you do not get the cash until maturity. That is phantom income, and it is genuinely annoying in a taxable account.

A reasonable structure is a nominal ladder for the near rungs, where inflation surprise has little time to compound, and TIPS for the rungs beyond five years, where it has plenty.

Three things, because misuse is more common than misconstruction.

Your emergency fund does not go in a ladder. Emergencies do not check maturity dates. That money stays liquid even though liquid pays less, and the yield you give up is the price of the option, not a mistake.

Money for a known expense inside twelve months does not go in a ladder either. Buy the single instrument that matures the week you need it. That is not a ladder, it is a matched liability, and it is the cleanest trade in finance.

And money that should be in equities does not belong here. A ladder is for capital you want to preserve with a real return on top. It is not a growth engine, and a five percent nominal yield against a three and a half percent inflation rate is a modest real return, not a windfall. Size it as the ballast it is.

The failure mode of a ladder is not construction. It is neglect. A rung matures, the cash lands in a settlement account, nobody notices for four months, and the money that was carefully earning five percent sits earning nothing.

Turn on auto roll at the broker if it is available, for every rung. That solves most of it mechanically.

For the rest, I run a scenario in Make.com off a simple sheet holding each rung with its maturity date, par amount, and coupon. Thirty days before any rung matures it emails me the amount coming due, what the current yield is at the tenor I would be rolling into, and what the rung I am replacing was earning. Three numbers, side by side, at a moment when I can still act deliberately rather than discovering idle cash in December.

The same sheet gives me total ladder yield, average maturity, and how much cash arrives in each of the next ten calendar years. That last column is what makes the strategy feel real. You can look at 2031 and see exactly what shows up.

For comparing instruments, I lean on Galaxy.ai. Bond offering pages and fund documents are dense in a way that hides the things that matter. I paste in what I am considering and ask the narrow questions: is this callable, and if so on what schedule. Is the yield quoted to maturity or to worst. What is the actual coupon frequency. For funds, what is the effective duration and average credit quality. Callable is the one that catches people. A callable bond hands you the worst of both structures, because it gets called away exactly when rates fall and you would have most liked to keep it.

Take 300,000 dollars of long term reserves, currently sitting in an intermediate bond fund.

Ten equal rungs of 30,000 dollars, one to ten years, in Treasuries at today's curve, blends out to something in the range of four and a half percent, call it 13,500 dollars a year. That is roughly comparable to what the fund yields, and if you live in a high tax state the Treasury exemption puts the ladder meaningfully ahead after tax.

But the yield is not the point. What you bought is certainty. Thirty thousand dollars comes back at par every year for ten years, on dates you know today, regardless of what the ten year does in between. You will never be forced to sell into a bad print, and you will never look at a statement in a rising rate year and have to decide whether to hold or fold, because there is no decision to make. The bond matures. You get paid.

That certainty is what the fund cannot sell you at any price. And in a moment where the committee is arguing about a hike while everyone else is positioned for a cut, being structurally indifferent to which way that argument resolves is worth considerably more than a few basis points.

I built the ladder construction sheet I actually use. You put in the total amount, the number of rungs, and the spacing, and it lays out every rung with its target maturity date and par amount. There is a live blended yield calculation, an after tax comparison that takes your state rate and shows Treasuries against corporates and CDs properly, a cash flow column showing what arrives in each of the next ten years, and a maturity tracker built to plug straight into a Make scenario if you want the alerts.

The paid community is open, and fixed income is one of the areas where a room genuinely beats an article.

Ladders are personal in a way most strategies are not. The right length depends on your liabilities, the right instrument on your state, the right account on what else you hold. Right now the room has people comparing broker auto roll implementations, which vary more than you would expect, and people in high tax states running the after tax comparison for the first time and finding they have been buying the wrong thing for years.

Inside you get my live positioning notes ahead of things like the September Fed meeting, the build sessions where we wire up Make scenarios together instead of you fighting the interface alone at midnight, and a room of people who think in systems rather than vibes.

Membership runs 29 dollars a month. The first 100 founding members can lock a lifetime seat for a one time 499 dollars, which means every system we ever build, forever, with no monthly bill again. Those seats do not come back. Reply with the word GRID and I will send you the founding member door.

For most of two decades, the correct amount of thought to give fixed income was almost none. Yields were low, the choice barely mattered, the money was made elsewhere.

No longer true, and the tell is that the committee is arguing about raising rates while the long end pays better than five percent. Conditions changed. Most portfolios did not.

You do not need a forecast to act on this. That is the nicest thing about a ladder. It does not require you to know where rates go, which is fortunate, because neither does anyone else, including the three people who dissented last month.

It just requires you to decide what dates you want your money back on.

Sunday we go quiet, and I want to pull on the thread running underneath all three of this week's pieces. Monday was about when you pay. Wednesday was about when you claim. Today was about when you get paid. That is not a coincidence, and I think it is the most underrated idea in personal finance.
