A high-yield savings account is a savings account — same FDIC coverage, same mechanics, same legal structure — that pays a much higher interest rate. Online banks pay 4.00-4.50% because they have no branch overhead. Big brick-and-mortar banks pay 0.01-0.05% because they don't need to compete for deposits. On a $100K balance the difference is roughly $4,200/year. The label 'HYSA' is marketing, not a product class.
A HYSA and a "regular" savings account are the same product type — the only difference is the interest rate the bank chooses to pay. Both are FDIC-insured bank deposits up to $250K per depositor per ownership category. Both let you deposit and withdraw cash. Both report interest on a 1099-INT.
The pricing gap exists because online banks (Marcus, Ally, Discover, Synchrony, SoFi, CIT) have no physical branches and need to attract deposits with rate. Big brick-and-mortar banks (Chase, BofA, Wells, Citi) have captive checking customers and don't need to pay competitive savings rates.
The interest rate difference is enormous. A 4.25% HYSA pays roughly 425 times more interest than a 0.01% Chase savings account on the same balance. On $100K, that's $4,250/year vs. $10/year. Over 10 years, $42,500 vs. $100. Same FDIC backing, same safety, same liquidity — wildly different outcomes.
The people leaving money at 0.01% are mostly doing so by inertia, not analysis. The big banks know this and rely on it.
Same $50,000 balance, three bank choices:
| Bank | APY (mid-2026) | Year-1 interest | 10-year interest (compounded) |
|---|---|---|---|
| Chase Savings | 0.01% | $5 | $50 |
| Bank of America Savings | 0.01% | $5 | $50 |
| Wells Fargo Way2Save | 0.01% | $5 | $50 |
| Marcus by Goldman Sachs HYSA | 4.20% | $2,100 | $25,950 |
| Ally Online Savings | 4.20% | $2,100 | $25,950 |
| Synchrony HYSA | 4.25% | $2,125 | $26,330 |
Sitting at Chase for 10 years on $50K costs you roughly $25,900 in foregone interest. That's a real money decision being made by default.
| Feature | Traditional savings | HYSA |
|---|---|---|
| APY | 0.01-0.10% | 4.00-4.50% |
| FDIC insurance | Yes, $250K/category | Yes, $250K/category |
| Minimum balance | Often $0-$300 | Often $0-$100 |
| Monthly fees | Often $5-12 (waivable) | Usually $0 |
| Branch access | Yes | No (online-only) |
| ATM card | Often included | Usually no |
| Linked checking required | Often yes | No |
| Mobile app | Yes | Yes |
| ACH transfer speed | 1-3 days | 1-3 days |
| Withdrawal limits | Historically 6/month (Reg D, now relaxed) | Same |
HYSAs are the right baseline for liquid cash. For amounts above your 6-12 month emergency buffer that you won't touch for 1+ years, a CD or MYGA can pay more and lock the rate. The decision isn't "HYSA OR CD/MYGA" — it's "what portion of cash in each."
