Moving to whichever account tops this month's rate list resembles chasing last year's best-performing fund — the top spot rarely stays fixed.
Many promotional rates last a limited window before reverting to a lower standing rate, which the chase often misses.
The durable, non-promotional rate is what you'll actually earn most of the time you hold the account.
The Household That Switched Banks Four Times in a Year
For example, consider a household that moved $30,000 between four different banks over twelve months, chasing each one's newest promotional rate, spending roughly six hours total on account openings, transfers, and closures. Their average effective rate across the year, once each promotional window reverted to its standing rate, came out close to 3.6%. A single account at a steady, competitive standing rate of 4.1% would have earned more, with a fraction of the effort and none of the account-closure friction.
John Bogle's published writing repeatedly warned against a closely related behavior in investing: chasing whichever fund had the best recent performance, a pattern he argued cost investors more in fees and mistimed moves than it ever gained. As of July 2026, this is especially important if you find yourself moving cash every time a new promotional rate tops the list, rather than checking whether your current rate is still reasonably competitive.
Why the Top Spot Rarely Stays Fixed
Per Bogleheads' summary of Bogle's published writing, performance-chasing is described as one of the most reliable ways savers reduce their own long-run outcomes, precisely because whatever looks best recently is rarely the best choice going forward. According to Vanguard's own corporate history, the firm's entire premise was built around resisting exactly this kind of short-term chasing.
The national average savings rate sits at 0.38% APY, while the best available standing rates run near 4.20% APY. A promotional rate that briefly exceeds even that top standing rate, then reverts after a few months, rarely beats a steady account at the standing top rate over a full year, once the reversion and switching friction are counted.
| Behavior | What it usually costs | Next check |
|---|---|---|
| Chasing each new promo rate | Reverted rates plus repeated switching friction | Compare the standing (non-promo) rate before moving |
| Staying at one competitive standing rate | Minimal friction, consistent yield | Recheck once or twice a year, not every promo cycle |
| Ignoring rate comparisons entirely | A large, uncorrected gap versus the best available | Compare against the national average and best available at least annually |
| Switching for a durable, meaningful gap | One-time effort, lasting benefit | Confirm the new rate has held steady for several months, not just a launch promo |
Comparing rates periodically has clear benefits: it catches a genuinely stale, uncompetitive account. The risk of chasing every promotional rate, as the four-bank household shows, is real switching friction for a rate that reverts before it's fully realized. However, that said, it depends on the size and durability of the gap, compared to a one-time promotional bump: a standing rate that's meaningfully and durably higher is worth switching for, while a short-lived teaser usually isn't. If you're deciding whether to switch, choose to move if the new account's standing rate has held steady and beats your current one by a meaningful margin; choose to stay if the advantage is mostly a temporary promotional window. This matters most for anyone who's switched more than once in the past year chasing a rate list. Both the account you're leaving and the one you're considering are FDIC-insured to the same standard limits, and Truth in Lending Act-style deposit disclosures make the standing rate directly comparable across institutions, so the decision is purely about durable yield versus switching effort, not safety.
The rate you'll earn most of the time is the durable, non-promotional one, not the launch-window teaser.
Account openings, transfers, and closures all cost time — a genuinely large, durable gap should clear that bar.
Checking once or twice a year catches real drift without turning into a full-time hobby.
Whatever looks best this month rarely stays best, in savings rates or in fund performance.
When This May Not Apply
If your current account's rate has genuinely fallen far behind the market for an extended period, switching once to a durably better standing rate is exactly the right move, not chasing. This is especially important if you haven't compared your rate in over a year, since that gap is a real, structural problem rather than promotional noise.
What to Do Next, in 20 Minutes
- Check your current account's standing rate, not any promotional rate you originally opened it for.
- Compare it to the best available standing rates, filtering out promotional-only offers.
- Calculate the durable gap, not the promotional headline.
- Decide once, not repeatedly — see when patience beats switching for the fuller version of this decision, will high-yield savings rates drop in 2026 for context on how durable today's top rates are likely to be, and the loyalty tax for the opposite failure mode: staying too long at a genuinely stale rate.
