The case for the RBA resuming interest rate cuts this year has been fairly clear: commodity prices have fallen more than expected; the $A has remained relatively high; while residential construction and consumer spending are okay the outlook for business investment has deteriorated pointing to overall growth remaining sub-par; and inflation is low. This has seen the cash rate fall to 2.25%. While the RBA left rates on hold at its April meeting, it retains an easing bias pointing to further cuts ahead.

However, the main argument against further rate cuts has been that the housing market is too hot and further rate cuts risk pushing home prices to more unsustainable levels resulting in a more damaging eventual collapse. But how real is this concern?
