The yield-and-card bundle with Brex Yield sweep above 4.5 percent on Essentials, paired with the Brex Card and bill pay.

PlanMonthlyWhat you get
EssentialsFreeFree Brex with banking, the Brex Card with rewards, expense management, bill pay, and Yield Treasury yielding above 4.5 percent
Premium$12.00/moAdds live chat, multi-entity support, custom approvals, and the Brex Travel platform; cheapest paid tier in the lineup
EnterpriseCustomCustom-quoted with ERP integration, dedicated success manager, and procurement workflows for scaling teams

Brex is the right pick when treasury sweep yield matters and you want banking, corporate card, expense management, and bill pay bundled. Brex Inc. founded 2017 in San Francisco by Henrique Dubugras and Pedro Franceschi. The wedge here is the highest treasury sweep rate in the lineup at 4.5 percent or above, paired with the Brex Card as the primary surface.

Essentials at $0 monthly covers the business account, Brex Card with rewards, expense management, bill pay, and Brex Yield treasury sweep yielding above 4.5 percent on idle balances. The operating checking pays zero APY; the yield lives in the sweep vehicle. Premium at $12 adds multi-entity support and the Brex Travel platform. FDIC sweep coverage scales to $6M via partner banks, the highest in the lineup. Brex Yield routes balances into government money-market funds.

The trade-off is audience filter and insurance posture. Brex retired its consumer-startup tier in 2022 and declines pre-revenue startups more often; bootstrap founders face signup friction. Brex Yield balances sit in SIPC-insured money-market positions, not FDIC-insured checking. The Brex Card requires daily auto-pay, not a 30-day float.

Pros

  • Brex Yield treasury sweep yields above 4.5 percent (highest in lineup)
  • $6M FDIC sweep coverage on operating side via partner banks
  • Banking plus Brex Card plus bill pay bundled at $0 Essentials
  • Premium $12 typical adds multi-entity support and Travel platform
  • Yield sweep into government money-market funds with daily liquidity

Cons

  • Brex Yield not FDIC-insured (SIPC instead); declines pre-revenue SMBs more often
  • Operating checking pays zero APY; Brex Card requires daily auto-pay not float
Essentials $0 + Yield 4.5%+Premium $12 typical$6M FDIC sweep on sideFree tier; no time limit

Best for: VC-backed startups, scale-ups wanting the highest treasury sweep yield with a corporate card bundled, and any team valuing integrated finance ops with yield.

Best treasury sweep yield for startups above the FDIC cap

Try MercurySee Mercury alternatives

The treasury sweep pick for startups, with idle balances yielding above 4 percent through partner money-market funds.

PlanMonthlyWhat you get
Mercury (free)FreeFree Mercury covering checking, savings, free domestic wires, USD international wires, the IO debit card, and Treasury sweep yielding above 4 percent
Mercury Plus$35.00/moAdds recurring invoicing, bill pay automation, custom roles and approvals, and priority support; the realistic upgrade once accounting load justifies the spend
Mercury Pro$350.00/moHigher card limits, full Treasury tier access for venture-backed runways, and a dedicated success manager

Mercury is the right pick when treasury sweep yield matters and the operating balance sits above the FDIC cap regularly. Mercury Technologies founded 2017 in San Francisco by Immad Akhund, Max Tagher, and Jason Zhang. The wedge here is sweep depth: balances above the FDIC-insured operating account auto-route into a partner money-market fund yielding above 4 percent.

Free at $0 monthly covers checking plus Treasury sweep yielding above 4 percent on idle balances through partner money-market funds. The operating checking pays zero APY; the yield lives in the sweep vehicle. Mercury Pro at $350 unlocks higher Treasury tiers and a dedicated success manager for VC-backed runways. FDIC coverage scales to $5M via Choice Financial Group and Evolve Bank partner sweep.

The trade-off is the insurance posture. Treasury sweep balances are not FDIC-insured because they sit in money-market fund positions; SIPC coverage applies up to $500K per account, but the funds themselves carry money-market NAV risk (the 2008 Reserve Primary Fund break is the textbook case). For SMBs wanting FDIC-insured yield instead, Bluevine wins.

Pros

  • Treasury sweep yields above 4 percent on idle balances at $0 monthly
  • $5M FDIC sweep coverage on the operating side via partner banks
  • Y Combinator-favored startup-banking default with brand recognition
  • Free domestic wires plus USD international wires on the free tier
  • Mercury Pro $350 unlocks higher Treasury tiers for venture-backed runways

Cons

  • Treasury sweep not FDIC-insured (SIPC instead); money-market NAV risk applies
  • Operating checking itself pays zero APY; yield lives only in sweep vehicle
Free + treasury 4%+ APY$5M FDIC sweepPro $350 unlocks higher tierFree tier; no time limit

Best for: Tech startups, venture-backed companies, and any SMB with operating reserves regularly above $250K wanting treasury sweep yield through a partner money-market.

Best direct APY business checking up to 4.25 percent

Try BluevineSee Bluevine alternatives

The direct-on-checking APY pick paying 2.0 percent Standard, 3.7 percent Plus, and 4.25 percent Premier.

PlanMonthlyWhat you get
StandardFreeFree Bluevine paying 2.0 percent APY on balances up to $250K, free unlimited transactions, and cash deposits at retailers
Plus$30.00/moRaises APY to 3.7 percent on $3M, adds sub-accounts, two free wires per month, and priority support
Premier$95.00/moLifts APY to 4.25 percent on $3M (highest in the lineup), removes wire limits, and adds a dedicated customer success manager

Bluevine is the right pick when FDIC-insured direct yield on the operating balance matters more than treasury-sweep depth. Bluevine Inc. founded 2013 in Jersey City by Eyal Lifshitz; banking via Coastal Community Bank. The wedge here is direct APY on the checking balance: the operating account itself yields with no separate sweep.

Standard at $0 monthly pays 2.0 percent APY up to $250K, the highest free-tier yield in the catalog. Plus at $30 raises APY to 3.7 percent up to $3M and adds sub-accounts. Premier at $95 lifts APY to 4.25 percent up to $3M. A cash-heavy SMB on a $500K balance earns roughly $5,000 a year on Standard, $18,500 on Plus, or $21,250 on Premier, all on FDIC-insured cash with full partner-bank sweep coverage to $3M.

The trade-off is the APY caps. Cash above $3M earns nothing on Plus or Premier, which matters for SMBs sitting on larger reserves. Bluevine has no native corporate card and retired its lending product line, so SMBs needing a credit-line product need an external pairing.

Pros

  • 2.0 percent APY on Standard up to $250K at $0 monthly fee
  • 3.7 percent APY on Plus up to $3M (raised from 3.0 percent in 2025)
  • 4.25 percent APY on Premier up to $3M (highest direct yield in lineup)
  • Yield paid on FDIC-insured balances with full pass-through to $3M
  • Cash deposits at retailers and mobile check deposit on every tier

Cons

  • APY caps apply: $250K Standard, $3M Plus and Premier; cash above earns zero
  • No native corporate card; Bluevine retired its lending product line
Standard $0 + 2.0% APYPlus $30 + 3.7% APYPremier $95 + 4.25% APYFree tier; no time limit

Best for: Cash-heavy SMBs and agencies on reserves $50K to $3M and businesses prioritizing FDIC-insured direct yield on checking.

How we picked

Each pick gets a transparent composite score from price, features, free-tier availability, and editor fit. Pricing flows from our live database, so when a vendor changes prices the score updates here too.

Composite weights: price 40%, features 30%, free tier 15%, fit 15%. Three picks ship a documented yield product, either as direct on-checking APY (Bluevine) or as treasury sweep into a partner money-market fund (Mercury, Brex). See parent /best/business-banking for non-yield picks.

We don't claim "30,000 hours of testing." Our methodology is the formula above plus the editor's published verdict for each pick. Verifiable, auditable, and updated when the underlying data changes.

How to choose your High-Yield Business Checking

Direct APY on checking vs treasury sweep into a money-market fund

The two yield models split sharply on insurance posture, tax handling, and liquidity. Direct APY on checking (Bluevine) pays interest on the operating balance itself: the cash sits in FDIC-insured checking with partner-bank sweep coverage to $3M, and interest is paid as ordinary income on a 1099-INT. The mental model is simple: checking earns interest like a high-yield personal account. Treasury sweep (Mercury, Brex) is different. Balances above the FDIC-insured operating threshold move into a partner money-market fund holding short-term Treasury or government-backed securities. The swept balances yield above 4 to 4.5 percent but sit in SIPC-insured money-market positions, not FDIC-insured checking. Yield reports as 1099-DIV. Liquidity is daily on both. The right pick depends on whether you prioritize FDIC coverage on the yielding balance (Bluevine) or the higher rate via sweep (Mercury, Brex).

Yield math for a $500K operating balance

Cash-heavy SMBs on a $500K operating balance see different annual yield depending on the pick. Bluevine Standard at $0 monthly pays 2.0 percent on the first $250K and 0 on the remainder, totaling $5,000 a year. Bluevine Plus at $30 pays 3.7 percent on $500K, netting $18,140 after fees. Bluevine Premier at $95 pays 4.25 percent on $500K, netting $20,110. Mercury Free pays 0 on operating and ~4 percent on the swept Treasury balance (assume $250K sweeps), totaling $10,000. Brex Essentials pays 0 on operating and ~4.5 percent on the swept Yield balance, totaling $11,250. Bluevine Plus and Premier win on direct yield above $250K; Mercury and Brex win on raw sweep rate but the FDIC-insured operating balance pays zero. Model the bill against your specific balance distribution.

FDIC partner-bank sweep is the load-bearing safety wedge

Standard FDIC insurance covers $250K per depositor per bank. All three picks ship partner-bank sweep networks that scale FDIC coverage on the operating side: Bluevine to $3M via Coastal Community Bank, Mercury to $5M via Choice Financial Group and Evolve Bank, Brex to $6M via partner network. The treasury-sweep balances on Mercury and Brex sit outside FDIC coverage in SIPC-insured money-market funds. The 2023 SVB collapse made the sweep-network exposure real: SVB customers with balances above $250K saw uninsured exposure until the FDIC announced a special intervention. Bluevine's direct-on-checking model pays yield within the FDIC-insured operating balance with full FDIC pass-through. For SMBs worried about the SIPC-vs-FDIC distinction on swept balances, Bluevine wins on insurance posture even at a slightly lower rate than Brex Yield.

When to graduate or pair across multiple banks (cross-link to parent)

Three triggers signal the need to pair multiple yield products. First, when reserves cross $3M, Bluevine's APY cap kicks in; pair Bluevine for the FDIC-insured first $3M with Mercury or Brex Yield treasury sweep above. Second, when the SMB needs banking plus corp card plus expense management bundled, Brex covers all three and Yield handles the sweep; Bluevine plus an external card means two vendor relationships. Third, when the business has multi-revenue streams needing operational segregation alongside yield, Relay Pro at 3 percent on the savings pocket pairs with Bluevine for operating yield. For non-yield picks across the catalog (Relay sub-accounts, Found Schedule C tracking, Novo, Wise Business multi-currency), see [our /best/business-banking guide](/best/business-banking).

Frequently asked questions

Is direct APY on checking better than a treasury sweep?

Depends on your priority. Direct APY (Bluevine) is paid on FDIC-insured checking balances with pass-through to $3M; the cash never leaves the operating account. Treasury sweep (Mercury, Brex) yields slightly higher (4 to 4.5 percent vs Bluevine 2.0 to 4.25 percent) but the swept balance sits in SIPC-insured money-market positions. For FDIC coverage on yielding cash, Bluevine wins. For the highest rate via partner fund, Mercury or Brex wins.

Are treasury sweep balances FDIC-insured?

No. Treasury sweep balances on Mercury and Brex sit in partner money-market funds, SIPC-insured to $500K but not FDIC-insured. The funds hold short-term US Treasury or government-backed securities, so credit risk is low, but technically the balance is a fund position. Bluevine direct-on-checking APY is different: yield is paid on FDIC-insured balances with partner-bank sweep coverage to $3M. For yield only on FDIC-insured cash, Bluevine is the only option here.

What is the highest-yield free business checking in 2026?

Bluevine Standard at $0 monthly pays 2.0 percent APY directly on the operating balance up to $250K, the highest direct on-checking APY in the free-tier set. Mercury Free at $0 ships treasury sweep yielding above 4 percent through a partner money-market fund (higher rate but SIPC instead of FDIC). Brex Essentials at $0 ships Yield treasury sweep at above 4.5 percent (highest sweep rate in the lineup). For free direct on-checking APY, Bluevine wins; for free treasury sweep yield, Brex Yield wins.

How does the APY math work for a $1M operating balance?

Bluevine Plus at $30 monthly pays 3.7 percent on $1M, netting $36,640 after fees. Bluevine Premier at $95 pays 4.25 percent on $1M, netting $41,360. Mercury Free pays 0 on operating; assume $750K sweeps to Treasury at 4 percent, totaling $30,000. Brex Essentials assumes $750K to Yield at 4.5 percent, totaling $33,750. Bluevine wins raw yield at $1M; the trade-off is FDIC-vs-SIPC insurance posture.

Do I need to pay tax on treasury sweep yield?

Yes. Both direct APY and treasury sweep yield are taxable as ordinary income federally. Direct APY (Bluevine) reports on a 1099-INT. Treasury sweep yield (Mercury, Brex) reports on a 1099-DIV as ordinary dividend income. Both flow to Schedule B on the personal return for sole proprietors. Some treasury money-market funds hold government securities exempt from state tax in some states, a small advantage for Mercury and Brex sweep for high-state-tax filers.

Can I switch banks without losing the APY rate?

Yes, but new APY starts when the new account funds. ACH or wire transfer takes 1 to 3 business days; APY accrues from deposit forward. For a $500K balance switching from 0 percent traditional to Bluevine Standard at 2.0 percent, math wins day one. Card-on-file across SaaS vendors take 30-plus minutes each. Plan a full quarter parallel-running both banks if switching from a long-standing incumbent.

What about Relay Pro 3 percent APY savings?

Relay Pro at $30 adds 3 percent APY on the Pro savings pocket only, not on operating checking. The wedge for Relay is Profit First sub-accounts (20 individual checking accounts on one login), not high-yield checking. We cover Relay on the parent [/best/business-banking guide](/best/business-banking) under the sub-accounts wedge. For high-yield checking specifically, the 3 picks here ship deeper yield products.

Should I keep operating cash and treasury cash at the same bank?

Optional. Many cash-heavy SMBs run single-bank (Bluevine Plus or Premier covers operating and yield; Brex Essentials covers operating and Yield treasury). Others run two-bank: operating at one bank plus a separate yield product at another for the bulk of reserves. The two-bank setup adds reconciliation overhead but optimizes each leg. For SMBs above $1M, pairing Bluevine Premier for direct yield up to $3M plus Mercury Treasury sweep above is a common pattern.

Does Subrupt earn a commission on these yield picks?

On all three. We disclose this on every /best page and structure composite to weight price 40, features 30, free tier 15, fit 15. None tuned by affiliate rate. Affiliate revenue flows on conversions to paid tiers (Bluevine Plus or Premier, Mercury Plus or Pro, Brex Premium). The free tiers earn nothing for us if you never upgrade. We pin Bluevine at the top because of FDIC-insured direct yield depth, not commission. The math behind every yield claim sources from the catalog and citations block.

How often is this guide updated?

Pricing and feature flags refresh from our catalog when a vendor updates a yield product. Editorial prose is reviewed quarterly. Bluevine raised Plus APY from 3.0 to 3.7 percent and Premier from 4.0 to 4.25 percent in 2025; Mercury Treasury yields shifted with Federal Reserve moves through 2025; Brex Yield held above 4.5 percent. We cross-check Bluevine, Mercury, and Brex APY rates monthly.
