Nominal Rate - Inflation
A Three-Decade Journey: Rates vs. Inflation
The RBA Cash Rate and annual inflation have had a dynamic relationship, with policy rates reacting to economic cycles, global crises, and inflationary pressures.
This chart visualizes the reactive nature of monetary policy. High cash rates in the early 90s and 2022-23 were direct responses to curb high inflation. Conversely, rates were slashed during the GFC and COVID-19 pandemic to stimulate the economy.
The Silent Tax: Unpacking Real Returns
Nominal returns are only half the story. Real return, which accounts for inflation, reveals the true change in your purchasing power. Often, even with positive interest, your money buys less over time.
1-Year Term Deposit: Nominal vs. Real Returns
The chart starkly contrasts the rate you see (nominal) with the rate you feel (real). In high-inflation years like 2022, despite attractive deposit rates, the real return was deeply negative, meaning purchasing power was lost.

The Recent Inflationary Surge: Impact on Your Term Deposits
From 2021 onwards, global and domestic factors triggered a significant inflationary burst. This period dramatically highlights the challenge for term deposits to maintain purchasing power despite rising nominal rates.
This chart specifically focuses on the 1-year term deposit real returns during the recent inflationary period. Notice the sharp decline into negative territory, indicating a loss of purchasing power, before a forecasted recovery in 2024 and 2025 as inflation eases.
How RBA Policy Reaches Your Bank Account
The RBA Cash Rate is the first domino. Its change triggers a chain reaction, but the transmission to retail term deposit rates isn't always perfect or immediate.
1. RBA Sets Cash Rate
Primary tool for managing inflation and economic growth.
2. Bank Funding Costs Change
Interbank lending rates shift, affecting banks' operational costs.
3. Market & Competition
Banks assess funding needs, competitor rates, and future expectations.
4. Retail Term Deposit Rates Set
The final rates offered to you, the saver, are determined.
This process highlights why the rate you get can differ from the RBA's headline changes. Factors like bank liquidity and competition create a "sticky" and imperfect transmission, which can be a timing challenge for savers.
Key Investor Takeaways
❶ Inflation is a Constant Threat
High nominal returns can be deceptive. Always calculate your real return (Nominal Rate - Inflation) to understand if your wealth is actually growing.
❷ Term Deposits are for Preservation, Not Growth
Historically, term deposits have often failed to beat inflation, making them tools for capital preservation and liquidity, not significant long-term wealth creation.
❸ Diversification is Paramount
To achieve real returns that consistently outpace inflation, a diversified portfolio including growth assets like equities or real estate is essential.
