Sri Lanka has declared every Wednesday a public holiday to conserve fuel as the island nation grapples with possible shortages in the wake of the US and Israel's war with Iran.
We must prepare for the worst, but hope for the best, President Anura Kumara Dissanayake said at an emergency meeting with senior officials.
This is the latest in a series of belt-tightening measures undertaken by Asian countries since the war hoked off the Strait of Hormuz, which used to carry millions of barrels of oil from the Gulf into the region.
Nearly 90% of all the oil and gas flowing through the strait last year was bound for Asia, which is the world's largest oil-importing region.
What are other Asian countries doing?
Elsewhere in Asia, authorities have resorted to a variety of austerity measures. In Thailand, for example, the government is urging people to swap suits for short-sleeved tees to reduce reliance on air conditioning, while in Myanmar, private vehicles are allowed only to operate on alternate days depending on their license plate numbers.
Bangladesh has brought forward Ramadan holidays in universities and introduced planned blackouts across the nation to conserve energy.
In the Philippines, some government offices have mandated that staff work from home at least one day a week, while President Ferdinand Marcos Jr has banned non-essential travel in the public sector.
And Vietnam is strongly encouraging citizens to stay at home more to conserve fuel, calling on people to ride bicycles, carpool, use public transport, and restrict personal vehicle use when unnecessary.
What else is Sri Lanka doing?
Sri Lanka's new four-day week will also apply to schools and universities, but it will not affect state institutions providing essential services, such as the health and immigration authorities.
Authorities chose Wednesday instead of Friday as the additional off day to avoid closing government offices for three consecutive days.
Motorists are now required to register for a National Fuel Pass which rations the amount of fuel people can purchase. This has sparked some dissatisfaction among citizens who feel the fuel quotas—15 litres for private cars and five litres for motorcycles—are too low.
The rationing mechanism was first implemented in 2022 during the country's worst economic crisis which saw it run out of foreign reserves and unable to import essential items and secure adequate fuel supplies.
Oil prices have soared since the US and Israel started bombarding Iran late last month, currently hovering at around $100 a barrel.
