The bank's monetary policy committee on Thursday voted 6-3 to keep the rate at 3.75 per cent, in line with the expectations of most economists. Policymakers have kept the rate at that level since December after four rate cuts in 2025. While the drop was bigger than economists expected, inflation remained above the bank's two per cent target for a 21st month in a row. Brent crude, the benchmark for world oil prices, jumped to more than $US100 a barrel on July 23 from less than $US71 three weeks earlier as the ceasefire between the US and Iran broke down. Brent crude traded for about $US92 a barrel on Thursday.
