The Reserve Bank of Australia's (RBA) current inflation forecast is largely based on the assumption that oil prices will fall relatively quickly. Its August Monetary Policy Statement assumed that Brent crude would return to the low-to-mid-$70 per barrel range within a relatively short period, and that inflation would revert to the target level as energy and transportation cost pressures from the Middle East conflict gradually subside.
However, the market has not fully accepted this assumption. Entering September, oil prices remained high, and the situation in the Middle East showed no significant easing. If energy prices fall more slowly than the RBA expects, related costs may continue to be passed on to transportation, goods, and services prices, making inflation more sticky and implying that monetary policy will need to remain restrictive for a longer period.
In this environment, long-duration fixed-rate bonds are more vulnerable to yield increases, while floating-rate notes (FRNs), whose coupon rates are repriced with benchmark rates such as the BBSW and have a shorter duration, are less reliant on a single interest rate direction and are more defensive during periods of uncertainty regarding the duration of high interest rates. FRNs issued by Australian banks and financial institutions are likely to attract more investment.
If high interest rates persist for longer, companies will face increased refinancing pressures, potentially widening credit spreads on Australian corporate bonds, particularly for highly leveraged real estate and consumer companies. In a high-interest-rate environment, banks may benefit from lower net interest margins, but this will be offset by slower credit demand and increased bad debt risk.
