Treasury Yields Are at Their Highest Since 2007. Here Are the 4 Retirement Numbers That Just Got Better and the 3 That Got Worse.

The 30-year Treasury yield traded between 5.32% and 5.33% on August 18. The last time it closed at or above 5.32% was June 12, 2007, when it finished at 5.35%. That is a span of 19 years and 2 months.

It did not happen in a day. The long bond has climbed all year: 5.18% on May 19, 5.27% on July 31, and a run of 5.24% to 5.31% from August 10 to August 17 that produced the highest close of 2026. This week extended the move rather than starting it.

The causes are structural, not political. Government spending is surging, the Treasury is issuing an unusual volume of long-dated debt, inflation has run above target five years running, corporations are borrowing heavily for the AI buildout, and traditional long-bond buyers have stepped back. Foreign holdings fell in June, with the United Kingdom, China and Japan all cutting. The latest 30-year auction cleared at its highest yield since 2001, and five of the previous seven 20-year auctions tailed.

It is not only an American story. Canada’s 30-year yield is at its highest since 2010, Germany’s is back to 2011 levels, and Japan’s is near a record.

The One Question That Decides Whether This Helps You

Every number below moved for the same reason. Which direction it moved for you depends on one question: are you buying future income, or cashing out a claim on it?

If you are buying, a higher yield is a discount. The same dollar buys a larger stream of future payments. If you are cashing out, the arithmetic runs backward. A lump sum is the present value of a future stream, and a higher discount rate makes that stream worth less today. Same rates, opposite result.

Better No. 1: Annuity Payouts Are Up 36%

This is the largest verified move here. In an August 5, 2026 survey of immediate annuity quotes, a $100,000 premium at age 65 on a life-only basis paid a man $679 a month at the best carrier, an 8.15% payout rate, and $630 on average, or 7.56%. For a woman, the best quote was $649 (7.79%) and the average $602 (7.22%).

In January 2021, the average quote for a 65-year-old man was $463 a month, a 5.56% payout rate. The average payout is up 36% in five and a half years.

Payouts rise less than yields do, and the reason matters. An immediate annuity check has three parts: interest, return of your own principal, and mortality credits from buyers who die earlier. Only the interest part moves with rates. Researcher Wade Pfau estimates a 1-point rise in rates lifts payout rates roughly 0.6 to 0.65 points, close to what happened here. Moody’s Aaa long corporate yield is up 3.31 points since January 2021 while payout rates rose 2.0 points, a ratio of 0.60.

Note which rate matters. Annuities are priced off long high-grade corporate yields, not the Fed’s policy rate. Moody’s Aaa 20-year-plus index was 5.76% in July 2026, its highest since November 2008.

Better No. 2: The Safe Withdrawal Rate Moved Up

Morningstar’s 2026 base case for a starting withdrawal rate is 3.9%, up from 3.7% in 2025, assuming 30% to 50% stocks and a 90% success rate over 30 years. With flexible “guardrails” spending, cutting in bad years and raising in good ones, the supported rate goes to 5.7%.

Read 3.9% carefully. It is higher than last year but still below 4%, so it is not a vindication of the 4% rule. That evidence comes from Bill Bengen, who created the rule in 1994 and has since raised his own number to 4.7% from 4.1% on a 55/40/5 portfolio. He calls 5.5% “more practical.”

Better No. 3: Cash and Short Treasuries Still Pay

Treasury bills, CDs and money market funds are the least complicated beneficiaries. They carry no duration risk, and you see the yield before you commit. For a sense of how far the curve has repriced, even the 20-plus-year Treasury ETF TLT carried a 30-day SEC yield of 5.18% on August 14, 2026.

Better No. 4: Social Security’s Trust Fund Earns More

The trust fund holds special-issue Treasury securities whose rate is set by formula: the average market yield on marketable interest-bearing federal securities not due or callable until after four years, rounded to the nearest one-eighth of a point. That rate is determined on the last business day of a month and applies to securities issued the following month, so the rate set August 31 governs September’s new issues.

One caveat: the fund is in drawdown. A higher rate on new issues helps at the margin and does not move the depletion date.

Worse No. 1: Pension Lump Sums Fell 20% to 30%

This is the highest-stakes item for anyone holding a buyout offer, and it has a clock on it. Lump sums are calculated under the IRS minimum present value segment rates in Section 417(e), published monthly and derived from corporate bond yields. Higher rates produce a lower present value, which produces a smaller lump sum for the exact same monthly pension benefit. Across 2022 through 2024, as rates climbed, corporate pension lump sums fell 20% to 30%.

Nothing about your pension changed. The price of buying it out did.

Worse No. 2: Long Bond Funds Are Down 42.8% From Their Peak

From its August 2020 peak through August 17, 2026, TLT has a total return of −42.8%. That is after reinvested distributions, which makes it what an investor actually lost, not a price chart.

The cause is duration. TLT’s effective duration is 14.81 years, a measure of how sharply price falls when long yields rise. Its net asset value was $81.35 on August 17, and it holds $45.4 billion. This was never one fund’s problem. In 2022 alone, TLT returned −31.2%, Vanguard’s VGLT −29.4% and the extended-duration EDV −39.2%. TLT is down 4.16% so far in 2026.

Worse No. 3: Reverse Mortgage Proceeds Are Down About $100,000

A HECM reverse mortgage does not price off the 30-year. It prices off the expected rate, which is built from the 10-year Constant Maturity Treasury plus the lender’s margin. The 10-year sits at 4.68%, and precision matters here: that is not a multi-decade high. The 10-year reached 4.98% in October 2023.

The effect is still large, because the principal limit factor that sets how much you can draw falls as the expected rate rises. On a $500,000 home, comparing the 3% floor that applied around 2021 with an expected rate near 7% today:

Those are gross figures, before the 2% upfront mortgage insurance premium and closing costs. The 2026 HECM lending limit is $1,249,125.

What to Recalculate This Month

• If you hold long bond funds, check total return since the 2020 peak. A one-year figure changes sign depending on the date you pull it.
• If you have a pension buyout offer, ask which month’s segment rates priced it. They reset monthly, and offers expire.
• If you are considering a reverse mortgage, ask for the expected-rate quote, not just the note rate. The expected rate sets your principal limit.
• If you are buying income, quote at least three carriers. In the August 5 survey, best versus average was $49 a month for life on the same $100,000.
