The Reserve Bank’s decision to raise the Official Cash Rate (OCR) to 2.5% signals a shift in the economic landscape, forcing investors to reconsider traditional definitions of financial safety. While bank accounts are often viewed as the default “safe” harbor, rising inflation and a weakening New Zealand dollar mean that cash holdings may lose purchasing power over time.
Defining ‘Now Money’ Versus ‘Later Money’
Financial strategy relies on the distinction between “now money” and “later money.” Money required for immediate expenses or short-term goals—typically within a one-year horizon—is best kept in liquid assets like savings accounts or term deposits.
Conversely, funds earmarked for five to ten years in the future are classified as “later money.” For these assets, the risk profile shifts. According to historical market data dating back to 1928, cash has provided an average annual return of 3.3%, while the sharemarket has delivered an average of 10%. Over long periods, the risk of inflation eroding the value of cash in a savings account often outweighs the short-term volatility of equities.
Did you know?
Historical data since 1928 indicates that while the sharemarket experiences periodic downturns, it has outperformed cash assets over the long term, largely because businesses have the capacity to adjust prices and innovate in response to economic shifts.
The Impact of Inflation and Currency Fluctuations
Inflation acts as a silent tax on cash reserves. As the cost of living rises—driven by factors such as global conflicts and supply chain pressures—money sitting in a stagnant account loses its real-world purchasing power. While the Reserve Bank utilizes OCR hikes to temper this inflation, these measures also increase the cost of debt, impacting mortgage holders and businesses.

The recent decline in the New Zealand dollar further complicates this dynamic. A weaker currency increases the cost of imported goods, such as fuel and food, directly affecting household budgets. However, this environment creates a divergent reality for exporters, who may see increased revenue when foreign sales are converted back into New Zealand dollars. Investing in businesses that can navigate these currency swings offers a potential hedge against the rising cost of living that cash savings cannot provide.
Pro Tips for Managing Inflation Risk
- Assess your timeline: Only keep money in high-interest savings if you need it within 12 months.
- Consider business ownership: For long-term goals, consider exposure to the sharemarket, where companies can raise prices to offset inflation.
- Monitor currency impact: Understand that imported goods will likely remain expensive, and adjust your budget or investment strategy accordingly.
Frequently Asked Questions
Why is the sharemarket considered safer for long-term money?
The sharemarket allows investors to own a portion of businesses that can adapt to economic changes by raising prices or innovating. Over decades, this adaptability has historically allowed shares to outperform the inflation-eroded returns of cash.
What is the risk of keeping all my money in a savings account?
How does the OCR hike affect my financial planning?
An increase in the Official Cash Rate makes borrowing more expensive, which is designed to slow the economy. For savers, it may lead to higher interest rates on deposits, but these often struggle to keep pace with the broader cost of living increases.
