Other than a brief spike in 2018, it’s been 15 years since short-term rates were high enough for most small-to-medium-size businesses (SMB) to worry about chasing yield on their parked cash. But that’s changed dramatically in the past 6 months. With “risk-free” rates pushing 5%, even a business with $50k in reserve (throwing off $200/mo) has the incentive to sweep that out of a non-interest checking account.

Are we about to see a rush of fintech startups serving the interest-sensitive small business market? Maybe, maybe not. It depends on whether VCs believe we’ll have a long-term run of rates higher than 3%. But what we will surely see is challenger banks dusting off their sweep features and emphasizing them in their marketing and branding.

Case in point: Just days after the Feds took over SVB, Mercury was in the market with Mercury Vault, offering $5 million in FDIC insurance by distributing balances across 20 insured banks. And we’ve also seen the launch of uniquely named and QED backed, Meow, with an FDIC-deposit-aggregation service Max Checking Account featuring $50 million of FDIC insurance.

Notes:
* The FAB score, Fintech Attention Barometer, is a proxy for the overall size of a private company since they typically do not release traditional metrics (# customers, deposits, AUM, etc). The score is based on VC funding, website traffic, mobile downloads, and the number of employees. It’s a work in progress, so expect changes in the formula.
**APY: Rate advertised at the time of publishing. May require a minimum deposit as listed in the next column.
***Funding: Includes equity and debt funding per Crunchbase.
****Meow offers an FDIC-insured product (rate on right) or direct investment in T-bills (rate on left)
*****Lili increased rate from 2.0 to 4.15% in September 2023
