In truth both of these factors, and others besides, have contributed to the rebound in inflation and interest rates that Australia has experienced this year.<\/p>\n
Oil prices have rebounded from just over US$70 a barrel in late June, when it briefly appeared that the Middle East conflict might be over, to more than US$100 a barrel in recent weeks, now that there seems little prospect of an imminent end to that conflict.<\/p>\n
Less well recognised, but no less important, the \u201ccrack spreads\u201d between crude oil prices and prices of refined petroleum products such as gasoline and diesel, have remained at elevated levels since the conflict began, and seem unlikely to come down given the damage that has been done to refining capacity in the Middle East and in Russia.<\/p>\n
Additionally, the US (the world\u2019s biggest oil producer) and China (the world\u2019s biggest oil importer) appear to have run down their reserves as far as they deem prudent, and so are now exporting less and importing more oil, respectively, than they had been doing in the early months of the conflict.<\/p>\n

Since then, this measure of underlying inflation has risen to 3.6% over the year to July.<\/p>\n So most of the increase in inflation which prompted the Reserve Bank to raise interest rates three times between February and May this year cannot be attributed to the conflict in the Middle East.<\/p>\n double quotation markThe rebound in Australian inflation began well before Donald Trump and Benjamin Netanyahu started the conflict in the Middle East<\/p>\n Rather, it reflects the persistent imbalance between \u201caggregate demand\u201d \u2013 the sum total of spending on goods and services by Australian households, businesses and governments \u2013 and \u201caggregate supply\u201d \u2013 the sum total of what is produced by businesses and governments, less what is exported to foreign countries, plus what is imported from abroad.<\/p>\n The growth of aggregate supply has been held down by our abysmal productivity performance<\/a> during this decade, which effectively sets a \u201cspeed limit\u201d on how fast our economy can grow, once we\u2019ve attained \u201cfull employment\u201d (which we have done since 2022), without generating inflationary pressure.<\/p>\n Growth in aggregate demand has been driven by both public and private spending.<\/p>\n Growth in public spending as measured in the GDP statistics has slowed \u2013 from more than 4% a year in real terms in 2023-24 and 2024-25 to 2% in 2025-26. But the national accounts measures of public spending only include direct spending by governments and government-owned enterprises on goods and services. They don\u2019t include other forms of government spending \u2013 in particular, cash payments to households and cost-of-living relief measures which the federal government and, of no less importance, state and territory governments have handed out in recent years.<\/p>\n skip past newsletter promotion<\/a>Free newsletter |When needed<\/p>\n Sign up to Breaking News Australia<\/p>\n Get the most important news as it breaks<\/p>\n after newsletter promotion<\/p>\n Thus the final budget outcome<\/a> document released on Monday showed that total expenses by the federal government rose by 5.1% in real terms in 2025-26, only marginally less than the 5.6% figure for 2024-25, and that both of those figures were higher than in all but five of the past 25 years.<\/p>\n And although most of the states and territories are yet to publish their equivalent documents, based on the estimates presented in their 2026-27 budgets it is likely that spending by state and territory governments and their instrumentalities rose by about 6% in real terms in 2025-26 \u2013 the largest increase since 2019-20.<\/p>\n Most of the cost-of-living relief given by the federal and state and territory governments, whether by way of cash handouts or tax cuts (such as the temporary halving of fuel excise), has been untargeted \u2013 that is, it has been given to households which might not need it as well as those which undoubtedly do. And most households appear to have spent it. That shows up in the national accounts as private sector spending \u2013 but it has really been facilitated by government policy.<\/p>\n In circumstances where inflation is running persistently above the Reserve Bank\u2019s target because aggregate demand is running persistently in excess of aggregate supply, what governments give by way of cost-of-living relief or tax cuts, the Reserve Bank takes away in the form of higher interest rates. Except that the burden of higher interest rates falls primarily on a smaller group of households \u2013 those with big mortgages \u2013 than those who received the cost-of-living relief and tax cuts.<\/p>\n The Reserve Bank itself has to accept some of the blame for the rebound in inflation, and hence in interest rates. That\u2019s because \u2013 with the benefit of hindsight \u2013 it cut interest rates prematurely last year. Its belief that inflation had sustainably returned to the 2% to 3% target band turned out to be wrong.<\/p>\n The RBA was of course under considerable pressure from the government to cut rates \u2013 recall, for example, Chalmers\u2019 unjustified assertion in August 2024 that the Reserve Bank had \u201csmashed the economy\u201d<\/a> (if it had, inflation wouldn\u2019t have rebounded in the way that it subsequently did). But \u2013 again, with the benefit of hindsight \u2013 the RBA should have resisted that pressure.<\/p>\n![\"\"](\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2026\/09\/1790736973_612_2998.jpg\")
