The ongoing military escalation in the Middle East could inflict economic losses of up to $299 billion across Asia and the Pacific, as higher fuel, freight and input costs ripple through regional economies, UNDP's latest assessment report release Tuesday showed.

The report said the shock is weakening household purchasing power, increasing food insecurity, straining public budgets and undermining livelihoods, particularly in countries heavily reliant on imported energy and food, as well as those exposed to Gulf trade routes, labor markets and remittance flows.

It estimated that under a 28-day disruption scenario, regional output losses could range between $97 billion and $299 billion, equivalent to 0.3% to 0.8% of GDP, with South Asia facing the most pronounced impact.

Around 8.8 million people across 14 countries could fall into poverty, including more than 5 million in Iran, where the poverty rate may rise from 36% to 41.5%, according to the simulations.

The report, prepared as of April 9, draws on inputs from 22 UNDP country offices covering 36 countries, alongside modelling and external data. It noted that outcomes will depend heavily on the duration and intensity of the conflict, with risks rising further if disruptions persist.
