THE COST
~7.5%
the 30-year mortgage in the US
The 30-year Treasury is the benchmark for long mortgages. With the long end stretched above 5%, the average mortgage sits near 7.5%, far from the 3% of 2021. That is the channel through which high rates actually slow the economy.

~7.5%
▲ almost double the ~3% of 2021
On a $300,000 mortgage, going from 3% to 7.5% means hundreds of dollars more each month, in interest alone.
Every point of mortgage rate adds hundreds of dollars a month to the average payment. At 7.5%, buying a home costs twice the interest it did in 2021.
- PAYMENT
- — The monthly mortgage bill: principal plus interest.
- INTEREST
- — What the bank charges to lend you the money.
READ
EDITORIALThe long rate is the economy's handbrake
“The Fed sets the short rates; the market sets the long ones. And it's the long one that charges your mortgage.”
The Fed sets the short rate, but it's the long bond that drives mortgages and long-term credit. That's where the braking shows up.
- SHORT RATE
- — Set by the Fed, for very short maturities.
- LONG RATE
- — The 10- and 30-year bond rate, set by the market.
COMPARISON
BOND TO PAYMENTHow the cost climbs with maturity
From 4.3% on savings to 7.5% on the mortgage: same money, very different price by maturity.
Short savings pay well, but the long bond drags the mortgage into painful territory.
- BILLS
- — Very short-term Treasury debt (months).
- MATURITY
- — The time until a loan or bond comes due.
DECISION
BUY OR WAITTwo paths when money is expensive
WAIT FOR LOWER RATES
The patient bet
- If rates fall, the future payment is much smaller.
- Meanwhile, short savings pay around 4.3% with no risk.
- Risk: if they don't fall, home prices can rise and eat the savings.
BUY AT 7.5%
The decisive bet
- You lock in the home today, without having to guess rates.
- You can refinance later if rates come down.
- Risk: you pay twice the 2021 interest from the very first month.
There's no free option: buying at 7.5% hurts today; waiting has its own cost if rates don't fall.
- REFINANCE
- — Swapping your mortgage for one with a better rate later.
- NO RISK
- — A near-certain return, like short-term Treasury bills.

Required with a mortgage
Vary by area
In the early years you pay mostly interest. A 7.5% rate makes that slice huge.
Early in a mortgage, almost all of it is interest. That's why the rate matters so much at the start.
- PRINCIPAL
- — The part of the payment that cuts what you owe.
- PAY DOWN
- — Gradually reducing the debt over time.
WATCHLIST
6 KEY ETFsThe assets that move with the long rate
| TLT | 88.20 | ▼ -1.8% | US 20+ year bonds. They fall when long rates rise: a direct mirror. |
| VNQ | 78.40 | ▼ -1.2% | Listed real estate. It suffers because mortgages track the 30-year. |
| ITB | 105.10 | ▼ -2.0% | Homebuilders. Sales stall with mortgages at 7.5%. |
| XLF | 47.05 | ▲ +0.4% | Banks. They gain margin when the curve steepens: the other side of the coin. |
| SHY | 82.10 | → +0.02% | US 1-3 year bonds. Barely sensitive to the long end: a calm refuge. |
| MBB | 92.80 | ▼ -0.7% | Mortgage bonds. They track the 30-year closely: the passthrough channel. |
When the 30-year rises, these six react. Each tells a part of the story.
- ETF
- — A listed basket that tracks an index or sector.
- CURVE
- — The map of yields by maturity. It steepens when the long end rises more.
