Got cash? Why Altruist paying 3.5% is still a bad home for yours
| 5 min | By Heath J. Harris
Altruist is paying about 3.5% on cash, but that is not the best home for a lump sum. Here is where we would rather put it and how direct indexing cuts your tax bill.
Summary
- Altruist high-yield cash pays around 3.5% APY as of late 2025, and rates change without notice.
- High-yield savings accounts have paid up to 5% in 2026, and Treasuries can beat the cash sweep too.
- A lump sum sitting idle in a cash sweep is a decision you have not made yet, not a strategy.
- Direct indexing with daily tax loss harvesting can capture roughly 1% to 2% in after-tax alpha for the right portfolios.
- Mid year is the time to check your gains and losses, not December when everyone is scrambling.
Yes, Altruist got cash: its High-Yield Cash account was paying about 3.45% APY as of late October 2025, and its own rate page has bounced between 3.16% and 3.45% since (Altruist, altruist.com/legal/interest-rate). That is a fine number for money that is passing through. It is a bad number for money that is standing still, and we will show you why.
There is a pile of cash sitting in a lot of retirement accounts right now, earning a rate someone picked for you, and most people treat it like a savings decision when it is really a decision they have not made yet. A cash sweep is a waiting room, not a plan.
Why 3.5% is not the win it looks like
Start with the competition. As of May 2026, high-yield savings accounts were advertising up to 5.00% APY (Fortune, May 22, 2026). NerdWallet flagged a promotional rate up to 4.1% at Forbright Bank as of July 17, 2026. The FDIC national average for savings was a miserable 0.38% (US News, June 15, 2026), so anything above 3% beats the herd. But beating the herd is a low bar. If a plain savings account is paying 4.25% to 5% and your custodian sweep is paying 3.45%, you are leaving real money on the table on a large balance.
Then there are Treasuries. Short government bonds can yield more than a cash sweep, and the interest is exempt from state tax (US News, savings guide). For a retiree in a high-tax state with a seven-figure balance, that state exemption alone can move the needle. The Fed left the federal funds rate at a target range of 3.50% to 3.75% on June 17, 2026, with the next meeting set for July 29 (NerdWallet), so cash yields are not collapsing tomorrow. That is exactly why it is worth shopping now instead of shrugging.
One more thing on the Altruist cash account specifically. It is not FDIC insured until the money actually lands at the partner program banks (Altruist, altruist.com/cash). And your advisor can charge their own fee on top (Altruist, cash-clients page). Read the fine print before you assume the 3.45% is what you keep.
What we would actually do with a lump sum
The hardest part of a lump sum is not the rate. It is not knowing what to do with it. You sold a house, took a buyout, or rolled over a 401k, and now there is a number sitting in cash that feels too big to move and too idle to leave.
We split it into buckets. Money you need in the next year goes somewhere safe and liquid, which is where a high-yield savings account or a short Treasury ladder earns its keep. Money with a longer horizon goes to work in the market on a schedule, not on a hunch. And here is the part most people miss: the way you invest that longer-horizon money can cut your tax bill for years.
Direct indexing and daily tax loss harvesting
Instead of buying an index fund, direct indexing buys the individual stocks inside the index. That sounds like a technicality until tax season. When you own the individual names, a computer can scan every day for a stock that is down, sell it to bank the loss, and buy something close enough to keep your allocation intact. A fund cannot do that at the security level (Altruist, personalized-indexing).
Altruist added a daily tax loss harvesting scan, capital gains budgeting, and gain and loss summaries to its tools in 2025 (Altruist, tax-management-upgrades). Daily matters. Losses are fleeting. If you only rebalance when the portfolio drifts, you miss the dip that showed up on a Tuesday and was gone by Friday (Altruist). Vanguard and Altruist both cite research pointing to roughly 1% to 2% in after-tax alpha per year for portfolios that regularly realize large gains (Vanguard advisors; Altruist tax-management). That is not a promise. It depends on your tax bracket, your gains, and market conditions. But on a large taxable balance it can dwarf the difference between a 3.5% and a 5% cash rate.
The rules matter. You can deduct up to 3,000 dollars of net capital loss against ordinary income per year for 2026, and losses above that carry forward to future years (ourtaxpartner.com, 2026 guide). You cannot buy a substantially identical security within 30 days before or after the sale, or the wash sale rule kills the loss (IRS, per filetax.com). And harvesting inside an IRA or Roth does nothing, because those accounts are already sheltered (filetax.com), which is why tax location matters more than asset allocation.
Why mid year is the moment
Most firms call November and December tax loss harvesting season (Greenbush Financial). We think that is backwards. By July you can already see the gains and losses that showed up in the first half of the year, including the ones you did not see coming. You have months to offset them instead of days. And remember settlement: with T plus one, a sale generally needs to be executed before the last business day so it settles by December 31 to count for the current tax year (filetax.com). Waiting until late December turns a strategy into a fire drill.
So, got cash? Good. Now stop letting the sweep account make your decisions for you. Match the money to the timeline, pick the vehicle that pays and shelters the most, and put your taxable dollars in a structure that harvests losses all year instead of once in a panic.

High-yield savings accounts have paid up to 5% APY in 2026, and short Treasuries can also beat a cash sweep. The right choice depends on your tax bracket and how soon you need the money.
What is daily tax loss harvesting through direct indexing?
Direct indexing holds the individual stocks of an index instead of a fund, so a daily scan can sell specific losers and bank the loss while keeping your allocation intact. Altruist added a daily tax loss harvesting scan to its tools in 2025.
Why do tax planning halfway through the year?
By mid year you can see gains and losses that showed up earlier in the year and start offsetting them, instead of scrambling in December. It gives you months to work rather than days.
