📈 Why do interest rates rise when inflation is high?
It's a question I hear regularly from clients.
Most people know the Reserve Bank raises interest rates to help reduce inflation. What many don't realise is that inflation affects much more than just the RBA's cash rate decisions.
When inflation rises, it can influence:
✅ Bond yields
✅ Bank funding costs
✅ Mortgage rates
✅ Business lending
✅ The Australian dollar
✅ Investment decisions across the economy
In fact, financial markets often start pricing inflation risk long before borrowers notice changes in lending rates.
I've put together a deeper look at the economics behind inflation, interest rates and borrowing costs, drawing on research from the RBA, IMF and leading economic texts.
If you've ever wondered why interest rates can remain high even when inflation appears to be easing, this may help explain what's happening behind the headlines.

💬 I'm interested in your view:
Do you think most Australians understand the connection between inflation, bond yields and mortgage rates, or do we focus too much on the RBA's cash rate alone?
