Invest in a Community Development Bank

Are you a socially responsible investor interested in supporting Community Development Banks? You can help by depositing money in a local Community Development Bank, providing capital to make new loans in communities left out of the economic mainstream. Your investment will help build affordable housing, establish community facilities, create jobs and revitalize low income neighborhoods.

Banking on Communities

The Banking on Communities Initiative is a joint effort by CDBA and Promontory Interfinancial Network, LLC to help investors secure large deposits in CDBA member banks. By making a deposit with a member bank through the Banking on Communities Initiative, you can provide capital for our banks to lend more money to projects in underserved communities. Through the Banking on Communities initiative you can access multi-million dollar FDIC insurance through a single bank relationship even if your deposits exceed the $250,000 FDIC insurance maximum (limits apply). As an added bonus, Promontory Interfinancial Network makes a charitable contribution to CDBA that we use to build the capacity of the community development banking sector. Since 2004, the Banking on Communities Initiative has helped CDBA membersraise billions of dollars in deposits.

How Does it Work?

Banking on Communities is built on the Certificate of Deposit Account Registry Service®, or CDARS®, and Insured Cash Sweep®, or ICS®, services provided by Promontory Interfinancial Network. With ICS and CDARS, investors can enjoy the protection provided by access to multi-million-dollar FDIC insurance and earn a return. When you place a large deposit with your bank using ICS or CDARS, that deposit is divided into amounts under $250,000 and is placed in deposit accounts at other Promontory Network member banks. Funds are placed into demand deposit accounts (using the ICS demand option), money market deposit accounts (using the ICS savings option), or into CDs using CDARS. By placing your funds in increments below $250,000, both principal and interest are eligible for FDIC insurance. When deposits are swapped on a dollar-for-dollar basis, the full amount of your original deposit comes back to your bank and the full amount of your deposit can go to work in your community through your CDBA bank. See how a CDBA member bank is using socially responsible, Insured Cash Sweep and CDARS deposits to make a meaningful difference in one local community.


Investing in a Community Development Bank with ICS and/or CDARS is simple. When placing a deposit through a CDBA bank with ICS and CDARS, you work directly with only one bank.

  • Your multi-million dollar deposits are eligible for FDIC insurance.
  • You earn one interest rate per CD term with CDARS
  • You receive one account statement per service.
  • Your account information is protected.

When deposited funds are exchanged on a dollar-for-dollar basis with other banks in the ICS or CDARS Network, a participating institution can use the full amount of a deposit placed through ICS or CDARS for local lending, satisfying some depositors’ local investment goals or mandates. Alternatively, with a depositor’s consent to certain types of ICS and/or CDARS transactions, the bank may choose to receive fee income instead of deposits from other banks. Under these circumstances, deposited funds would not be available for local lending. Placement of funds through the ICS or CDARS service is subject to the terms, conditions, and disclosures in the service agreements, including the Deposit Placement Agreement (“DPA”). Limits apply and customer eligibility criteria may apply. In the ICS savings option, program withdrawals are limited to six per month. Although funds are placed at destination banks in amounts that do not exceed the FDIC standard maximum deposit insurance amount (“SMDIA”), a depositor’s balances at the relationship institution that places the funds may exceed the SMDIA (e.g., before ICS or CDARS settlement for a deposit or after ICS or CDARS settlement for a withdrawal) or be ineligible for FDIC insurance (if the relationship institution is not a bank). As stated in the DPA, the depositor is responsible for making any necessary arrangements to protect such balances consistent with applicable law. If the depositor is subject to restrictions on placement of its funds, the depositor is responsible for determining whether its use of ICS or CDARS satisfies those restrictions. ICS, Insured Cash Sweep, and CDARS are registered service marks of Promontory Interfinancial Network, LLC.
