Berliner Tageszeitung - World Bank chief economist warns of hunger risk from war in Iran

"You have about 300 million people who suffer from acute food insecurity already," Indermit Gill said. "That'll go up by about 20 percent very, very quickly," as knock-on effects grow.

Gill spoke on the sidelines of the International Monetary Fund-World Bank Spring Meetings in Washington.

The blocking of the Strait of Hormuz, a key oil supply route, has sent fertilizer prices soaring since they rely on oil-based inputs.

Higher prices for fertilizers, which are used in agriculture, may entice countries to halt food exports and hoard more food for themselves, further driving up food prices.

"Those export bans scare us massively," Gill told AFP.

Most exposed are people in countries that are at war or have fragile governments.

If the situation isn't resolved soon, "hunger will start to stalk these countries massively."

Currently, the shortage of petrochemicals and their economic effects are being most felt in Asia, Gill explained, but "as the crisis gets longer, it's very rapidly going to spread first to Africa."

"The food that's in the market right now has already been grown," Gill said, but the real effects could be felt in a few months.

- Lower growth, higher inflation, more expensive debt –

Low-income people across the world tend to spend a larger share of their earnings on basic needs like food and fuel.

"If you get inflation in, especially in the kind of things that the poor consume relatively more often, that inflation is going to hurt massively," Gill went on.

Gill also warned that inflation – not just in food prices – could rise from about 3 percent globally to as much as 4.7 percent this year, in the most extreme scenario where the conflict stretches to August.

At the same time, global growth could be cut by as much as 40 percent on a yearly basis, if the crisis drags on.

Higher inflation mixed with lower growth would be a "double whammy" for the debt sustainability of poor countries, further hindering their ability to deal with this and future crises.

Gill warned that many headline figures for regional growth may appear too rosy, as the massive US, Chinese, and Indian economies, which are generally more insulated from external shocks, tend to drag up estimates.

When you remove them from the estimates, "you start to see a lot more vulnerabilities," Gill said.

"And by the way, that extreme scenario, with every passing day, is not that extreme of a scenario -- because we're getting closer and closer to August."
