At least 145 countries have reported increases in petrol prices since the attacks on Iran by the US and Israel began on February 28.

Since the United States and Israel launched their war on Iran six months ago, petrol prices have risen in at least 145 countries, adding to the burden on consumers worldwide.

The figures are based on data from GlobalPetrolPrices, which tracks fuel prices in 170 countries and territories. Petrol prices in Myanmar rose the most, increasing by 56 percent from $0.77 per litre of 95-octane fuel on February 23 to $1.20 on August 17. Bhutan recorded the next-largest increase at 55 percent, followed by Cuba at 51 percent, the UAE at 50 percent and 48 percent in Nigeria.

In 25 other countries, most of them oil producers with heavily subsidised fuel, prices have either remained unchanged or fallen by single digits.

The table below lists the 145 countries where petrol prices at the pump increased over the past six months.

How higher fuel costs shrink your driving range

Before the war, the US national average for a gallon [3.78 litres] of regular petrol was $2.94. It now costs $4.09, an increase of 39 percent, according to AAA Fuel Prices, which tracks retail fuel prices for the American Automobile Association (AAA).

The extra cost directly affects how far people can travel. Before the war, $50 worth of fuel in the US could take a family sedan roughly 718 km (446 miles). Today, the same amount takes you about 536 km (333 miles) – 183 km less, a 25 percent reduction in driving distance.

That gap varies depending on where you live.

How high oil costs drive up the price of food

Oil prices and food prices move in lockstep, with energy prices affecting every stage of the food supply chain, from the fertilisers used in the fields to the trucks that carry food from field to supermarket shelf.

Rising oil prices also directly impact shipping and the cost of transport.

“The lifeblood of the global economy is transport,” economist David McWilliams told Al Jazeera. “It’s getting stuff from A to B – it’s a logistics problem, a supply chain problem and ultimately transportation is the energy of the global economy.”

In lower-income countries, where populations spend a far greater share of their earnings on food and import large quantities of grain and fertiliser, rising oil prices could rapidly translate into food shortages.

What products are made from oil and gas?

Oil and gas are used for far more than just fuel. They are raw materials for thousands of everyday products.

Plastics, including water bottles, food packaging, phone casings and medical syringes, are all derived from crude oil.

Crude oil is also the hidden ingredient in synthetic fabrics, such as polyester, nylon and acrylic, which are used to make everything from sportswear to carpets. It also underpins the cosmetics industry, as it is used to make products such as petroleum jelly (Vaseline), lipsticks and concealers.

Household items also rely on oil-based ingredients, with laundry detergents, dishwashing liquids and paints all derived from petroleum products.

The global food supply is essentially built on natural gas in the form of fertilisers, used to enhance crop yields and ensure that food production can meet demand.
