The RBA unanimously raised the cash rate by 25 bps to 4.60%, citing the materialisation of some upside risks to inflation and the need for further tightening in financial conditions. However, the statement contained a subtle dovish shift in its forward guidance. The Bank removed its previous reference to inflation returning to the midpoint of the target range in late 2027, instead saying that further tightening is warranted to bring inflation back to target within a “reasonable period.” It also changed its guidance on future hikes from raising rates if upside risks materialise to doing so “if needed,” suggesting a higher hurdle for additional tightening.Governor Bullock reinforced that message in her press conference. She said the RBA considered only holding rates or hiking by 25 bps at this meeting, while acknowledging that inflationary pressures are likely to last longer than previously expected. At the same time, she stressed that monetary policy works with a 12–18 month lag and that the full impact of the hikes already delivered has yet to pass through the economy. She also said that if inflation continues to fall, no further hikes may be needed, while a recession is not the central case. This suggests the RBA increasingly prefers to wait and assess the effect of existing tightening rather than automatically respond to every strong inflation reading.The Bank is therefore keeping another hike on the table, but without committing to one. Tomorrow's August CPI will remain important, but Bullock explicitly cautioned against placing too much weight on a single monthly reading. Overall, the RBA's message is becoming less inclined toward further tightening but still prepared to act if inflation pressures persist.In the markets, we've been seeing some tentatively optimistic price action, with oil prices falling steadily throughout the session on hopes of some kind of deal from the ongoing US-Iran talks. As a reminder, the Iranian Foreign Minister Araghchi said he expected a formal answer today to Tehran's proposal to reopen the Strait of Hormuz. Diplomatic sources to Al Hadath said that mediators are working on a US-Iranian understanding that paves the way for reviving the Islamabad MoU. However, Washington And Tehran feel "frustration over the results of the current negotiations". This article was written by Giuseppe Dellamotta at investinglive.com.
