| Best APY right now: | Capital One 360 -- 4.10% APY, $0 minimum, branch access |
| Best for full banking ecosystem: | Ally Bank -- 3.00% APY + Savings Buckets + checking integration |
| Best for simplicity: | American Express HYSA -- 3.10% APY, single-purpose savings, Amex login |
All rates verified June 29, 2026. Capital One 360 leads by 100 to 110 basis points above the other two. On $10,000, that is $110/year extra. On $50,000, it is $550/year.
High-yield savings account rankings shift whenever banks reprice. In June 2026, Capital One 360 Performance Savings has pulled decisively ahead of two common alternatives, Ally Bank HYSA and American Express High Yield Savings, by a full 100 to 110 basis points. Whether that gap justifies switching depends on what else you want from your savings account. Here is the full comparison.
Capital One 360 Performance Savings: 4.10% APY
Capital One 360 Performance Savings pays 4.10% APY on all balances as of June 2026 with no minimum deposit and no monthly fee. It is the only account in this comparison with physical locations: Capital One Cafes in major metros and traditional branches. Interest compounds daily and credits monthly. FDIC insured up to $250,000.
Verdict: Best for savers who want the highest available APY among major online banks right now, with the option to walk into a branch when needed.
Best for: Anyone with $10,000 or more in savings who wants to maximize annual yield. At $25,000, Capital One earns $275/year more than Ally. At $50,000, it earns $550/year more.
What we like: 4.10% APY is the highest of the three in this comparison as of June 29, 2026 (verified against Capital One's published rates page). AutoSave feature automatically moves surplus cash from 360 Checking to savings. The Capital One mobile app is consistently rated highly for UX. Linked 360 Checking available.
Watch-outs: Capital One has historically cut its HYSA rate faster than Ally during Federal Reserve rate-reduction cycles. During the 2024 Fed cuts, Capital One moved sooner than Ally, meaning Ally's lower rate today may be more stable going forward if the Fed cuts again. Capital One does not offer a Savings Buckets equivalent for goal-based savings organization.

Ally Bank's High-Yield Savings Account pays 3.00% APY as of June 2026, 110 basis points below Capital One. The rate gap is real money -- but Ally offers one feature neither Capital One nor Amex replicates: Savings Buckets, which let you divide one savings account into up to 30 labeled buckets (emergency fund, vacation, car repair) with individual targets and progress tracking. For goal-based savers, this avoids the clutter of maintaining multiple accounts.
Verdict: Best for savers who want a complete online banking ecosystem -- checking, savings, CDs, and investment accounts -- under one app, and who value savings goal organization over maximum APY.
Best for: People who want to automate savings goals and who use or plan to use Ally's Interest Checking account. The combination of Savings Buckets and a linked checking account is Ally's core differentiation.
What we like: Savings Buckets are genuinely useful for tracking multiple financial goals within a single account. Ally's customer service has earned strong marks historically. Automatic savings rules and round-up transfers available. No fees, no minimums.
Watch-outs: At 3.00% APY, Ally is 110 basis points below Capital One. On a $25,000 balance, that is $275/year forgone. Ally has no physical branches. If your primary concern is APY maximization and you do not need Savings Buckets, Ally is the weakest pure-rate option of the three in June 2026.
Compare All HYSA Rates NowAmerican Express HYSA: 3.10% APY, Simple
American Express High Yield Savings Account pays 3.10% APY as of June 2026, splitting the difference between Ally (3.00%) and Capital One (4.10%). It is a deliberately minimal product: no checking account, no savings buckets, no investment integration. For Amex credit cardholders who want to park cash in a trusted brand without establishing a new banking relationship, the simplicity is the value proposition.
Verdict: Best for existing Amex customers who want a single-purpose savings account at a meaningful rate without switching primary banking institutions.
Best for: People who already use American Express for credit cards and want to hold emergency fund savings within the same app ecosystem. Acceptable rate, minimal friction, trusted brand.
What we like: No monthly fee. No minimum balance. FDIC insured (American Express National Bank, member FDIC). The Amex brand carries broad consumer trust. 3.10% is meaningfully above the national savings average, which remains below 0.5%.
Watch-outs: At 3.10% APY, Amex is 100 basis points below Capital One. On $25,000, that is $250/year less than Capital One earns. There is no linked checking account, no Savings Buckets, no branching ecosystem. Transfer times to external banks are 1 to 3 business days. This is a single-purpose savings product -- if you want any banking feature beyond storing and earning interest, you need accounts elsewhere.

Compare HYSA Rates NowFrequently Asked Questions
Is Capital One 360 Performance Savings FDIC insured?
Yes. Capital One Bank (USA), N.A. is a member FDIC institution. The 360 Performance Savings Account is insured up to $250,000 per depositor per ownership category. For balances above $250,000, consider spreading across multiple FDIC-member institutions or using different ownership categories (individual vs. joint) to extend coverage.
Will Capital One 360 cut its rate if the Federal Reserve cuts rates?
Yes. Capital One 360's 4.10% APY is variable and will adjust with the federal funds rate. Historical data shows Capital One cut its HYSA rate faster than Ally during the 2024 Federal Reserve rate-cut cycle. If rate stability matters more than current yield, consider putting a portion of your savings in a CD to lock in today's rate, while keeping the remainder in a variable HYSA.
What is the difference between Capital One 360 AutoSave and Ally Savings Buckets?
Capital One AutoSave automatically transfers a set dollar amount or percentage from your 360 Checking to savings on a schedule you define -- it is a recurring transfer tool, not a goal-tracking tool. Ally Savings Buckets divide your existing savings account balance into up to 30 named virtual buckets with individual targets, progress bars, and labels (vacation, emergency fund, car repair). The mechanics are different: AutoSave is about getting money into savings automatically; Buckets is about organizing and tracking savings goals you have already accumulated. Ally's Buckets are more powerful for goal visualization. Capital One's AutoSave is simpler.
Can I hold both a Capital One 360 account and an Ally account at the same time?
Yes. There is no legal restriction on holding HYSA accounts at multiple banks simultaneously. Many savers use Capital One 360 as their primary HYSA for the 4.10% yield and Ally for goal-tracking with Savings Buckets. Both accounts are separately FDIC-insured, so together they can hold up to $500,000 in insured deposits.
Is American Express High Yield Savings safe?
Yes. American Express National Bank is a member FDIC institution. The High Yield Savings Account is insured up to $250,000 per depositor per ownership category. American Express Bank is one of the most well-capitalized banking institutions in the United States. The primary risk with any HYSA is APY variability, not institution safety.
Why did Capital One 360 Performance Savings jump to 4.10% APY?
Capital One raised its 360 Performance Savings rate to 4.10% APY effective June 25, 2026, according to multiple bank-rate aggregators and Capital One's published rates page verified on June 29, 2026. The specific driver of this particular rate increase is not publicly disclosed -- Capital One adjusts its HYSA APY based on competitive positioning, funding costs, and the federal funds rate environment. At 4.10%, it is now one of the highest rates among widely-known national banks without an introductory-rate expiration date.
