The Southeast Asian region is in the brisk for rising debt bills as a result of the region’s currencies slump.

The amount that the area’s companies, banks and governments must repay on US dollar-denominated bonds would rise 8 pct next year to $19.7 billion, just as a slide in Asia’s currencies to the weakest this decade threatens to push up servicing costs on that debt.

Here is a list of the ten non-financial firms in Southeast Asia with the most dollar bonds due in the next 12 months, according to data compiled by Bloomberg. Companies with income in the greenback and currency hedges would be cushioned:

Singapore Telecommunications Ltd., PT Bumi Resources, Olam International Ltd., BOC Aviation Ltd., Alliance Global Group Inc., Perusahaan Listrik Negara, Berau Coal Energy Tbk, SM Investments Corp., Travellers International Hotel Group Inc., Carmen Copper Corp.

A few of the above companies have their say about the currency depreciation in Asian province, and their hedged and unhedged effects of their FX exposures.

In some cases, we noticed the dollar debt has been entirely hedged. The slump in domestic currencies does not affect the debt service of our foreign currency debts. There will be no increase in the debt service cost because our foreign currency debts are fully hedged including the interest cost.

BOC Aviation for an instance, we have a massive warchest both to support our CapEx and to refinance our existing commitments," said Timothy Ross, head of investor relations and corporate communications at the aircraft leasing company based in Singapore.

“There is no issue with regards to refinancing any of the debt as and when it comes due. All of our assets are in U.S. dollars. Our revenues are all in U.S. dollars and 92 pct of our costs are in U.S. dollars. We’re a pure U.S. dollar play which I guess if anything should make us more attractive given the strength of the U.S. dollar.”
