he biggest rally in the Thai baht in eight years is driving down inflation and helping the country's bonds outperform all other investment-grade emerging market debt in Asia.
Almost a decade after the 1997 devaluation of the baht triggered an economic crisis in Asia, Thailand's debt is posting the biggest gain among seven Asian countries included in indexes compiled by JPMorgan Chase & Co. Investors have reaped total returns of 3.6 percent this year, according to JPMorgan.
``We are bullish on the bond market because interest rates have peaked and inflation is slowing,'' said Jessada Sookdhis, who helps run the equivalent of $524 million in debt at Ayudhya JF Asset Management in Bangkok.
Central bank Governor Pridiyathorn Devakula said on Aug. 7 he would stop raising interest rates. Since the Bank of Thailand's last increase on June 7, the baht has gained 2.2 percent. Ten-year bond yields have fallen by a quarter percentage point in the past seven weeks.
Thailand will benefit from the lower yields when the central bank this week auctions 4 billion baht ($106.8 million) of 5.4 percent securities due in 2016. The 0.10 percentage point drop in yields since the previous sale on July 26 suggests the government will save an annual 4 million baht in interest. The bonds now yield about 5.47 percent.
The baht has climbed 9.5 percent this year, more than the Indonesian rupiah, Singapore dollar and 12 other Asian currencies. The last time the baht gained more was in 1998, when the currency surged 28 percent as it rebounded from the devaluation a year earlier.
Asian Crisis
Interest costs for Thailand have plunged in the past eight years. The government sold 10-year bonds in December 1998 at a yield of 8.50 percent. The country's local-currency debt rating was lifted one step since then, to A by Standard & Poor's. Debt rated BBB- and higher is investment grade.
Thailand has posted the biggest gains among the seven emerging-market borrowers in Asia with investment-grade ratings tracked by JPMorgan. Thailand has outpaced a 2.7 percent return by Hong Kong and 2.69 percent gain for South Korea. The group also includes China, Taiwan, Malaysia and Singapore.
The yield on 10-year securities may fall to 5.32 percent by Dec. 31, said Pongtharin Sapayanon, who helps oversee $1.6 billion including Thai bonds at Aberdeen Asset Management in Bangkok. That would hand investors a 3.1 percent return, including reinvested interest.
Investors at the Aug. 23 sale may bid for twice the amount of 10-year bonds the government plans to sell, said Pongtharin. At last month's auction, investors submitted offers for 2.44 times the amount issued.
The government also plans to sell 10 billion baht of 5.5 percent bonds maturing in 2008 tomorrow. Two-year note yields have fallen 22 basis points in the past seven weeks, the steepest decline since April.
Political Stalemate
Some investors may be reluctant to bid until after an Oct. 15 election, said Lee Boon Keng, a bond strategist at DBS Bank Ltd. in Singapore, Southeast Asia's biggest lender.
Prime Minister Thaksin Shinawatra, who dissolved parliament in February, called elections following demands he resign after his family sold a stake in Shin Corp., Thailand's biggest mobile- phone company, for $1.9 billion.
``You're not going to rush into the market now,'' said Lee, the DBS strategist. ``There's an absence of political clarity.'' Bonds may rally after the vote, bringing the 10-year yield down to 5 percent by Dec. 31, he said.
Slower Growth
Thailand's growth is weakening as a 16 percent increase in oil prices this year and the looming election damp consumer and government spending. The $169 billion economy may slow to a 3 percent pace in the last six months of the year, half the rate in the first quarter, Pridiyathorn said this month.
The central bank boosted its benchmark interest rate 13 times to rein in inflation, which slowed to 4.4 percent in July, the lowest rate since June 2005. Consumer prices in May climbed by 6.2 percent, matching the highest since September 1998.
The median forecast of economists surveyed by Bloomberg at the start of the month is for gross domestic product to increase 4.2 percent this year, the least since 2001.
``The economy's going to get weaker and that's going to provide some support for bonds,'' said Joel Kim, who helps oversee $8.5 billion of emerging-market debt at ING Investment Management Asia Pacific in Hong Kong. Kim bought 10-year Thai securities about a month ago.
