A retiree in their 60s planning a 15/85 equity-to-fixed-income split can reduce market swings, but advisers say the fixed-income sleeve still needs inflation protection to preserve purchasing power over a 30-year retirement.

A 15/85 portfolio cuts risk but needs an inflation hedge
A retiree in their 60s who caps equities at 15 percent can cut market swings, yet advisers warn the fixed-income 85 percent must still outpace inflation across a retirement that could last three decades.
"You saved enough, and you want to sleep at night, so we build you a paycheck, not a portfolio to babysit," said Stoy Hall, a certified financial planner and founder at Black Mammoth.
The reader, retiring in March 2027, wants minimal stock exposure after building savings. Advisers point to investment-grade and Treasury bond funds, Treasury ladders with one-, two- and three-year rungs, municipal bonds, high-yield money market funds near 3.5 percent, Treasury bills around 3.7 percent, CD ladders, TIPS and I-bonds.
Over a retirement that could span 30 years, a 15 percent equity allocation leaves the portfolio exposed to inflation, so the fixed-income portion must keep pace with the cost of living.
Bonds and ladders anchor the income side
Bonds fit retirees because they deliver predictable income without the stock market's swings. Paul L. Gaudio, a certified financial planner and director and wealth planner at Crestwood Advisors, said a broad investment-grade bond fund or a pure Treasury fund can offer competitive yields without the work of tracking individual maturity dates. For retirees with specific spending needs coming up, a Treasury ladder may work better, he said, splitting money across one-, two- and three-year Treasuries so a rung matures each year and frees principal for spending or reinvestment at prevailing rates.
Municipal bonds deserve a look for retirees in high tax brackets, Gaudio said, because their interest is exempt from federal tax and home-state bonds usually avoid state tax too. The trade-off is lower headline yields and thinner liquidity than Treasuries, so they work best as part of the mix. Bond interest still counts toward modified adjusted gross income, which can trigger Medicare Part B premium surcharges known as IRMAAs that add hundreds of dollars a month.
Inflation is the quiet threat to a 'safe' portfolio
Hall cautioned that over a 30-year retirement, a 15 percent equity allocation exposes the portfolio to inflation risk. TIPS adjust a bond's principal for inflation, while I-bonds adjust their interest rate, though I-bonds carry an annual investment limit of $10,000 per individual. "With most of your money in fixed-rate assets, this is your hedge against the one force that quietly shrinks a 'safe' retirement," he said.
Liquidity matters too. Hall recommends keeping one to two years of living costs in high-yield money market funds paying near 3.5 percent or Treasury bills around 3.7 percent, and building a CD ladder for mid-term cash so money lands on a schedule and nothing is sold at a bad time.
For the most risk-averse, Gaudio said an immediate annuity funded with a portion of wealth can guarantee income for life, but principal is locked up, fees can be heavy and inflation protection is often absent. "It works best for money the client won't need for flexibility or legacy purposes," he said.
Gaudio said a 15 percent equity allocation makes most sense for clients spending the money within five years or those with spending needs well below the portfolio's long-term potential. The right mix depends on income needs, spending patterns and tax situation, he said, adding that "that's where working with a planner earns its keep."
