Petrol prices near 12-month highs
Weekly petrol prices

Petrol prices: According to the Australian Institute of Petroleum, the national average price of unleaded petrol rose by 9.0 cents a litre last week to a near 12-month high of 154.1 cents a litre (highest since week to November 4 2018). The lift in prices was influenced by sharp price increases of 19-22 cents a litre in Sydney, Melbourne and Brisbane, reflecting the end of discounting cycles.

Highs & Lows: Tennant Creek in the Northern Territory has the dearest petrol (192.7 cents a litre); Gunnedah in NSW has the cheapest (138.6 cents). Encouragingly, a number of NSW and Queensland towns that are significantly affected by drought, currently have relatively low petrol prices.

Movements in the petrol price can affect consumer spending, and in turn, prospects for retailers.

What does it all mean?

• Filling up the car with petrol is the single biggest weekly purchase for most families. Abstracting from discounting cycles, underlying pump prices are likely to be little-changed in the short-term. The problem is that it is hard to abstract from discounting cycles in East Coast and Southern mainland capital cities. In short, the cycles make no sense and don’t reflect the realities of global oil markets. The city that best reflects what is truly going on in global oil markets is Perth, the city with a discrete weekly pricing cycle. The Perth pump price fell 1.3 cents last week to 144.6 cents a litre.

• Petrol prices may seem high, but in actual fact, a year ago pump prices were even higher than now. The good news is that prices are slowly easing in Sydney, Melbourne and Brisbane.

• The US Nymex oil price stands at a 1-month high of US$56.66 a barrel. But at home the wholesale (or terminal gate) price actually stands at a 6-week low of 132.6 cents a litre. If you add in a 12 cent gross retail margin, the pump price should be around 145 cents a litre – as is the case in Perth.

• The big picture story on oil prices is mixed. The OPEC+ grouping of oil producing nations (OPEC, plus producers like Russia) are focussed on restricting production to support oil prices. But on the other side of the equation, the global economy has softened, reducing demand for oil. There is also uncertainty on issues like the US-China trade negotiations and Brexit and that uncertainty is keeping a cap on oil prices.

What is the importance of the economic data?

• Weekly figures on petrol prices are compiled by ORIMA Research on behalf of the Australian Institute of Petroleum (AIP). National average retail prices are calculated as the weighted average of each State/Territory metropolitan and non-metropolitan retail petrol prices, with the weights based on the number of registered petrol vehicles in each of these regions. AIP data for retail petrol prices is based on available market data supplied by MotorMouth.

What are the implications for interest rates and investors?

• Fuel prices fell by around 2.3 per cent in the September quarter after a 10.2 per cent lift in the June quarter, keeping a lid on headline inflation. The Consumer Price Index is out on Wednesday and we expect that headline inflation rose by 0.5 per cent in the September quarter to be up 1.7 per cent on the year.

• Commonwealth Bank Group economists expect another interest rate cut in February 2020.
