Westpac has increased its fixed home loan rates for terms ranging from one to three years, effective Tuesday.

The bank also raised rates on select term deposits.

Management attributed the move to escalating tensions in the Middle East, signaling that geopolitical risk is now directly influencing retail lending pricing in New Zealand.

This adjustment follows a recent 25 basis point increase in Westpac’s floating interest rates, which was implemented in line with the Reserve Bank of New Zealand’s latest monetary policy tightening.

The combination of central bank policy transmission and geopolitical risk premiums is compressing margins for borrowers and increasing the cost of capital for households.

The bank’s decision highlights how external shocks are being priced into domestic financial products.
