Interest Bearing (Savings) Accounts



Interest Bearing Accounts (<<account_interestBearingUS>> or <<subAccount_interestBearingUS>>) (also referred to as savings accounts) are depository accounts that pay interest but don't enjoy the full capabilities of standard deposit accounts (DEPOSIT-US)(also referred to as checking accounts). Interest Bearing Accounts are FDIC insured up to $250,000 and can be opened for both individuals and businesses. Regulation limits these account types to six withdrawals per month, after this point it is not possible to generate additional withdrawals.

Types of Interest Bearing Accounts Offered

  • Interest Bearing Deposit Accounts (<<account_interestBearingUS>>): FDIC insured interest bearing depository accounts held in the end user's name at Synapse's bank partners.

  • Interest Bearing Sub-Accounts (<<subAccount_interestBearingUS>>): Sub-Accounts held on the end user's behalf within a platform's FBO account. These accounts are held within the platform’s FBO account, so they require less KYC from users. Sub-Accounts are eligible for FDIC insurance with the appropriate disclosures and account setup (click here for more info). Interest accrued on the FBO account as a whole will be distributed among Sub-Accounts as "rewards" (rather than interest).

Common Use Case

Interest Bearing Accounts are equivalent to a traditional bank's savings account and are commonly used to emulate them.
