Credit unions vs banks: how to choose

7 min read · Before you start: Lesson 18 on deposit protection · Updated 2 November 2026

Key terms in this lesson: credit union · dividend · fixed deposit (all defined in the glossary)

Banks and credit unions both take your savings and lend to you, and from the counter they can look alike. Underneath they work differently: who owns them, how your money earns, how safe it is and how you borrow. This lesson compares the two so you can use each where it fits.

Who owns the institution

A bank is owned by shareholders, and customers deposit and borrow. A credit union is a co-operative owned by its members. Each member has one vote at the annual general meeting regardless of how much they hold, and the board is usually made up of elected members. Many are built around a common bond such as a workplace, profession, church or community. A January 2024 industry report put the sector in Trinidad and Tobago at 129 credit unions and roughly three-quarters of a million members, so they are a large part of everyday finance here.

How your money is held and what it earns

• At a bank, a savings or fixed deposit is a deposit that earns a stated rate of interest.
• At a credit union, members hold shares and may also keep savings. Instead of interest on shares, the members may receive a dividend, which is declared at the annual general meeting and is not guaranteed in advance.
• Access can differ. Many credit unions have rules about when and how you can withdraw shares, so ask before you assume the money is as reachable as a bank savings account.

Protection: the big difference

The Trinidad and Tobago Deposit Insurance Corporation insures deposits at member institutions: commercial banks, finance houses, and trust and merchant banks. According to the Central Bank’s public education material, the limit rose to TT$200,000 per depositor, per institution, from 1 October 2024. The same material states that deposits in other institutions, such as credit unions, are not covered by this arrangement.

Credit unions have historically been supervised under the co-operative framework. For years there have been proposals to move supervision to the Central Bank under a dedicated Credit Union Act, and a January 2024 report said reforms, including deposit insurance, were still under consideration. Laws change, so check the current position with the Central Bank and the co-operative authorities. Lesson 18 covers deposit insurance in detail.

Borrowing

Credit unions often lend to members against their savings or shares, and many arrange repayment by deduction at source from salary. Banks usually assess your income and credit record. Neither is automatically cheaper. Rates and fees vary by institution, so compare actual offers rather than assuming. Ask whether the rate is quoted flat or on a reducing balance (see Reading a loan offer), what fees apply, and whether your shares are held as security while the loan runs.

Questions to ask before depositing

• Is it properly registered, and who supervises it?
• Does it publish audited financial statements, and are they recent?
• How is the dividend decided, and what was it in recent years?
• When and how can I withdraw my shares or savings?
• Is there any member protection fund, and exactly what does it cover?
• How are loans approved, and what happens to my shares if I borrow?

Using both

One way households approach it: keep the emergency fund and any large balance at an institution where deposit insurance applies, and use a credit union for share savings and for loans you have compared. That is an illustration, not a recommendation. The right mix depends on your goals, how soon you need the money and how comfortable you are with the protection each offers.
