With Treasury Yields Near 4.5%, One Couple Rethinks When to Claim Social Security.
Quick Read
-
Delaying the higher earner’s Social Security to 70 permanently lifts the survivor benefit from $3,000 to $3,720 monthly, which is something bonds cannot replicate.
-
High yields ease funding the income bridge to 70, but interest income can trigger IRMAA Medicare surcharges and make more Social Security benefits taxable.
-
Using pre-Social Security years for Roth conversions typically delivers more long-term value than chasing an extra half point on a CD ladder.

Picture a married couple in their mid-60s, both healthy, staring at a brokerage statement that finally looks generous again. Their money market fund pays close to what a decent bond used to pay. A five-year Treasury clips about 4.2%, and the 10-year sits near 4.5%. For the first time in years, safe income feels real. So they are asking a fair question: if bonds pay this well, should the higher earner still wait until 70 to claim Social Security, or claim now and let the portfolio keep compounding?
This is a real thread in retirement forums right now. One version reads almost like a script: husband and wife, both 66, want to hold off claiming until 70, but they are watching CD offers and wondering if delaying is still the smart move when guaranteed yields look this good.
The interest rate backdrop is what makes the question new. Fed Chair Kevin Warsh has been public about not being comfortable with inflation above 2%, most recently indicating that inflation expectations had cooled, while the funds rate has held at 3.75% since December. Higher for longer has become a planning assumption.

The one number that settles most of the debate
For a married couple, the decision that matters most is when the higher earner claims. The reason is what happens to the survivor.
Social Security pays roughly 8% more for every year the higher earner waits past full retirement age (FRA), up to 70. Those delayed credits are baked into the survivor benefit for whichever spouse outlives the other. If the higher earner’s benefit at a FRA of 67 would be $3,000 a month, waiting until 70 pushes it closer to $3,720. When the first spouse dies, the survivor steps up to that larger amount for the rest of their life.
That is the piece high yields cannot replicate. A 4% or 5% Treasury pays until it matures. A larger Social Security check pays until the second spouse dies, adjusts for inflation every year, and cannot be outlived. For a couple where one spouse earned meaningfully more, delaying the higher earner is essentially cheap longevity insurance for the survivor.
The lower earner is a different story. Their delay mostly benefits them personally, and if their spouse’s record is bigger, survivor mechanics will eventually overwrite their own benefit anyway. Claiming earlier for the lower earner is often defensible.
How the bridge actually gets paid for
Here is where today’s yields do change the calculus, just not in the direction people assume. High rates make the bridge to 70 easier to fund. A couple who needs, say, $60,000 a year from savings to cover the gap can get a meaningful chunk of that from interest alone when short T-bills yield nearly 3.8% at 13 weeks and close to 4% at a year. I-bonds are currently paying a 4.3% composite rate with inflation protection built in.
The wrinkle: that same interest income counts toward provisional income. Pull $40,000 out of taxable bonds and CDs while collecting Social Security, and a larger share of the benefit becomes taxable. The same income can also push a couple across an IRMAA threshold (the income-based surcharge that raises Medicare Part B and D premiums) two years later. It is worth modeling before assuming the bridge is free.
What to think through before deciding
High yields changed the bridge. They did not change the case for the higher earner waiting.
-
Frame the higher earner’s claim age around the survivor. Yields move. A locked-in benefit for the longer-living spouse does not.
-
Use the bridge years to manage taxes alongside funding spending. Roth conversions in low-income years before Social Security starts often matter more than squeezing an extra half point out of a CD ladder.
Every couple’s picture is different. Health, the size of the earnings gap between spouses, pensions, and how much guaranteed income already covers the essentials all shift the answer. The math above is the frame. The details are where a careful afternoon with a spreadsheet, or a fee-only planner, tends to pay for itself many times over.
