Diesel and gasoline price forecast

by Neven Valev, updated August 1, 2017

Looking at recent history, Brent crude oil prices seem to fluctuate within the 45 - 55 USD per barrel range. When oil prices decline to about 45 USD per barrel, demand picks up and some production facilities are no longer profitable. These factors stop the decline in oil prices and start to push them higher. When oil prices reach about 55 USD per barrel, fracking in the U.S. becomes more profitable and the added supply pushes oil prices down. It seems that this pattern will continue for some time.

Implications for fuel prices

You could look at the current oil prices and anticipate a move up or down depending where we currently are in the 45-55 USD per barrel range. Then, draw conclusions about the implications for fuel prices. Note that every 10 percent change in oil prices, for example from 50 to 55 USD per barrel, leads to about 3 percent change in fuel prices in Europe and about 7 percent change in the U.S. In principle, the higher the fuel taxes, the smaller the change in fuel prices for a given change in oil prices. These numbers are the same for gasoline and diesel.

So, if you are in a country with high fuel prices (see the global rankings for gasoline and diesel), an increase/decrease in oil prices from 45 to 55 USD per barrel would lead to about 5-6 percent increase/decrease in fuel prices. If you are in a country with about average fuel prices, the change would be double - about 10-12 percent. If you are in a country with low fuel prices, that usually means that the government regulates or subsidizes prices. Then, oil prices have less direct impact.

Exchange rates and other factors

Besides oil prices, the value of the USD affects significantly fuel prices because crude oil is traded in USD. For example, when the euro appreciates against the USD, it becomes cheaper to buy crude oil with euro and, hence, fuel prices in Europe decline. This is important because currencies could be just as volatile as crude oil prices. Currency values are influenced by various factors across countries that cannot be summarized here. Be mindful, however, that fuel prices can change because of changing currency values even if crude oil prices are stable. For example, as the ruble depreciated, gasoline prices in Russia increased in 2014 despite the drop in oil prices.

Crude oil prices and exchange rates explain about 90 percent of the fuel price changes in countries with free fuel markets. Seasonal factors also play a role as fuel prices are higher in the summer due to greater demand. Also, in most countries we observe a slight but persistent trend up in fuel prices even if oil prices and exchange rates stay the same as inflation pushes up the marketing and distribution cost. Moreover, fuel taxes tend to increase over time. However, all of those additional factors are less important in most countries. It is currency values and, globally, oil prices that make the big difference.

Long-term oil price outlook

I’ll wrap up with a note on the longer-term outlook for oil prices. Basically, I don’t see much scope for significantly higher prices. There is growing demand for oil products from the emerging markets but this is countered by the declining demand from developed countries where environmental standards are getting tougher and electric vehicles are spreading. Also, demand in the emerging markets would probably taper off as cleaner technologies become cheaper and more accessible. On the supply side, fracking is becoming ever more efficient allowing pumping at lower prices. There also seem to be abundant proven reserves of oil for decades to come.

These factors may not be enough to press crude oil prices much lower than their current levels because on a global level incomes are growing and, so far, this generates additional demand for oil. However, they put an upward limit on crude oil prices. There may be occasional spikes due to supply disruptions but they would be temporary. As economic growth around the world picks up, crude oil prices may drift up on a more sustained basis but probably not above a 60-65 USD per barrel level in the next few years.
