Hong Kong(CNN Business) A series of deadly attacks could deal a body blow to one of Asia's fragile economies.
Bombs ripped through churches and luxury hotels in Sri Lanka on Easter Sunday, killing at least 250 people and injuring hundreds. Targets included the upmarket Shangri-La hotel in the capital, Colombo.
Four days after the coordinated attacks, the Sri Lankan Health Ministry revised the death toll, saying 253 people had died. That toll is significantly lower than the 359 initially reported to CNN by a Colombo police spokesman this week.
At least 39 of those killed in the explosions were identified as tourists from countries including the United Kingdom, Denmark, Australia and India.
On top of the heavy loss of human life, the attacks could cause serious damage to Sri Lanka's economy, which depends on tourism.
The island nation in the Indian ocean welcomes about 2.5 million visitors a year from around the world. Data from the World Travel and Tourism Council show that the industry is one of the biggest contributors to the country's economy, supporting about 1 million jobs. It is also the third largest source of foreign currencies, according to research firm Capital Economics.
Tourism's importance has grown rapidly in the last 10 years, after the Sri Lankan government defeated the rebel Tamil Tigers organization to end nearly three decades of civil war.
"Tourism has been a big success story for Sri Lanka over the last decade," said Alex Holmes, Asia economist at Capital Economics.
No group has yet claimed responsibility for the attacks and the police investigation is ongoing. But international tourists are now likely to stay away.
The Sri Lankan government has declared a state of emergency starting midnight Monday. The US State Department has urged travelers to exercise increased caution, warning that "terrorist groups continue plotting possible attacks."
"The violence is likely to hit the tourism industry hard, at least in the short term," Holmes added.
One business feeling the impact immediately is Sri Lankan Airlines, the national carrier. CEO Vipula Gunatilleka told CNN Business that hundreds of passengers have canceled bookings since Sunday's attacks. The airline is allowing passengers to delay or change flights without paying a fee.
"Since the hotels were attacked and all that, you'd expect more and more [cancellations], especially the foreign bookings and all of that to come down," he said. "That's the reality."
Gunatilleka, whose airline carries about one-third of people flying into Sri Lanka, said it was too early to speculate on how long the damage to tourism will last. "We are looking at [the] immediate impact and how to handle that," he added.
India is one of the biggest sources of foreign visitors. One tour group said it had not yet seen any cancellations.
"At the current time we are yet to receive any cancellation requests and it is early days yet to assess impact to the destination," Mahesh Iyer, executive director of Thomas Cook India, said in a statement.
The US dollars, Chinese yuan and other currencies tourists spend in Sri Lanka are vital to the economy.
Sri Lanka needs a constant flow of currency to keep up payments on its foreign debt. The debt owed by the Sri Lankan government amounts to about 80% of the country's annual economic output, statistics show, and it is rising.
Much of this debt is owed to countries in currencies other than the Sri Lankan rupee, analysts point out. In 2018, Moody's and Fitch both downgraded the Sri Lankan government's credit rating, citing questions over its ability to repay its debts.
Like other emerging markets, Sri Lanka has also seen foreign investors yank funds out of the country amid sustained US dollar strength.
If investors lose confidence in Sri Lanka's capability to repay its debts, that could prompt the nation's currency to weaken further. "This will further weigh on the economy," Capital Economics' Holmes said.
