Falling interest rates & term deposits

As interest rates decrease and many Kiwi wonder what to do with their Term Deposits, Deposits Product Manager Jeremy Smit and Kiwibank Economist Sabrina Delgado have teamed up to share their insights on how to make your Term Deposits work for you.

    Understand how & why interest rates change

    Our experts agree that it's important to understand how and why interest rates change when deciding the length of your Term Deposit. "When economic growth slows, interest rates are slashed to stimulate growth. As a result, all Term Deposit rates move into a lower range.

    "On the other hand, when the economy is heating up, interest rates are lifted to cool the economy down and tame inflation. And in this case, Term Deposit rates move into a higher range," says Sabrina Delgado.

    We don't need to look back far to see this in action and Sabrina shares some recent interest rates highs and lows:

    • Historic lows: We saw interest rates hit historic lows during the COVID-19 pandemic. Interest rates were slashed to boost economic growth and Term Deposit rates fell below 1%.
    • Aggressive hikes: From late 2021 interest rates were hiked aggressively by the Reserve Bank of New Zealand - Te PÅ«tea Matua (RBNZ) which, in turn, caused banks to increase interest rates and savers enjoyed Term Deposit rates above 5%.
    • A downward shift: In 2024, the RBNZ commenced its Official Cash Rate (OCR) rate-cutting cycle, marking a decrease in interest rates, including Term Deposit rates. This downward trend has continued into 2025 with further cuts to the OCR.

    Locking in for longer

    The length of time you can commit your money to a Term Deposit will depend on your savings goals and your need to have cash on hand for emergencies and unexpected purchases, says Jeremy Smit.

    "Historically, we’ve generally seen short Term Deposits offer lower interest rates, but provide greater flexibility in getting your money back sooner. While longer Term Deposits may offer higher rates, the trade-off is that your funds aren't accessible for longer," he says.

    When rates change, it's a balancing act of maximising your returns while managing the risk of interest rates changing while your money is locked away, says Jeremy. "In a decreasing rates environment like we’re in now, short Term Deposits may offer higher rates, however, locking in your Term Deposits for longer periods at current rates can help manage the risk of earning lower returns if rates decline in the future," he says.

    Get Kiwibank's latest interest rate forecast

    Once you've got a sense of your goals and budget, you can look to our Economists' interest rates commentary and forecasts to help you make an informed decision about the term length of your deposit.

    Our Kiwibank Economists forecast that the RBNZ will deliver further cuts to take the cash rate to 2.5% by the end of 2025. "Inflation has stabilised within the RBNZ's 1-3% target band. We're now more concerned about the emerging global growth risks amid tariff trade wars. The change in environment demands lower interest rates," says Sabrina.

Locking in your Term Deposits for longer periods at current rates can help manage the risk of earning lower returns if rates decline in the future."
