How Global Events and Market Volatility Can Impact Your KiwiSaver — And Why Staying Steady Matters

Written by Booster | March 2, 2026

 

How Global Events Can Impact KiwiSaver (Market Update)

Periods of heightened global tension can create short-term volatility in financial markets. When uncertainty increases, investors often see movement in:

  • Global share markets
  • Oil and commodity prices
  • Currency markets
  • Inflation expectations

Because KiwiSaver funds invest both in New Zealand and internationally, short-term market fluctuations can occur during these periods.

Market Volatility Is Not New

Global markets have historically experienced volatility during:

  • Geopolitical tensions
  • Economic slowdowns
  • Interest rate cycles
  • Commodity price shocks

"While headlines can create uncertainty, markets have historically recovered over the long term as economies adapt and stabilise. It can be difficult to see your balance lower at times like this, but making rushed decisions in response to the headlines can sometimes lock in losses."

- Simon O'Grady, Booster Chief Investment Officer

It’s important to stay the course so you benefit when markets recover.

If you have a long time to go before you need to access your KiwiSaver savings, you have time on your side. The current ups and downs shouldn’t be of concern. 

If you are planning on accessing your KiwiSaver savings in the next couple of years, say for a first home or when you retire, you are likely to already be in a more conservative fund which tends not to be as heavily impacted. 

As uncomfortable as it might be watching the markets go down, the best thing you can do is hang tight and wait for the upside.

Our investment team continually assesses global and local developments and manages our funds with the aim of building strong results in the longer term. 

Frequently Asked Questions:

Does global conflict affect KiwiSaver?

Global events can cause short-term market volatility. Because KiwiSaver funds invest in international markets, global developments may temporarily affect returns. However, KiwiSaver is designed as a long-term investment.

Should I switch my KiwiSaver fund during market volatility?

Changing funds during periods of volatility may lock in losses. It’s important to choose a fund based on your long-term goals, timeframe and comfort with risk — not short-term market movements.
