Jan. 9 (Bloomberg) -- The bond market is telling Li Ka-shing, Asia's richest man, he's sitting on a Chinese property bubble that's bigger than the one deflating in the U.S.

Bonds of China's Agile Property Holdings Ltd. yield 7.17 percentage points more than U.S. Treasuries, double the premium in July and 1.79 percentage points more than the debt of Los Angeles-based KB Home, which has the same credit ratings. Agile, a housing developer in the southern province of Guangdong, and Country Garden Holdings Co., China's most-profitable builder, canceled debt sales in November when borrowing costs climbed.

As China's government attempts to cool property prices with limits on lending, developers are in a land grab. Li, who made his fortune in Hong Kong real estate, Chinese billionaire XuRongmao, who owns Shimao Property Holdings Ltd., and hundreds of local developers boosted investment 29 percent in the first eight months of 2007, the National Bureau of Statistics said.

``If the government decides to impose further restrictions, most if not all of the developers will go bankrupt, depending on the severity of the restrictions,'' said Eugene Kim, chief investment officer of Hong Kong-based Tribridge Investment Partners Ltd., a $200 million hedge fund. ``That makes us very selective in terms of which bonds we buy and the spreads we require to compensate for risk.''

Kim said he has trades set up that would profit from a decline in prices. New York-based Merrill Lynch & Co., the world's biggest brokerage, rates China property companies ``underweight,'' meaning investors should own a smaller percentage of the debt than contained in benchmark indexes.

Home Prices

Home prices in Shenzhen, a city north of Hong Kong, were 18.6 percent higher in November than a year earlier, according to a National Development and Reform Commission survey. They rose 14.9 percent in the capital city of Beijing and 16.4 percent in Beihai, in Guangxi province.

The People's Bank of China last month raised its benchmark one-year lending rate to a nine-year high and increased reserve requirements to the most since at least 1998. The government increased the minimum down payments on apartments to 40 percent from 30 percent in September.

Signs of a shift are already emerging. The nation's largest publicly traded developer, Shenzhen-based China Vanke Co., sold property worth 4.23 billion yuan ($582 million) in November, 18 percent less than in October.

Most Vulnerable

Chinese developers are among the most vulnerable of any group in Asia to downgrades because a slowdown in home sales would deplete cash, said Clara Lau, an analyst at Moody's Investors Service in Hong Kong.

``They have been growing aggressively, with the view that if they don't buy now, it will be more expensive for them later'' to acquire land, Lau said.

Standard & Poor's cut the credit ratings of Greentown China Holdings Ltd., the largest builder in Zhejiang province, one level to BB- on Dec. 3 due to ``increasingly aggressive land acquisitions.'' Its $400 million of 9 percent bonds yield 11.2 percent, up from 9.6 percent in November.

The risk of Shimao and Agile defaulting on their debt rose to a record today, credit-default swaps show. The cost of protecting the bonds of Shimao and Agile against default increased by as much as 80 basis points, the contracts' biggest rise, to 560 basis points and 650 basis points, respectively, at 5:13 p.m. in Hong Kong, according to BNP Paribas SA.

Higher Cost

Each basis point, or 0.01 percentage point, on a contract protecting $10 million of debt from default for five years adds $1,000 to the annual cost.

Credit-default swaps are financial instruments based on bonds and loans that are used to speculate on a company's ability to repay debt. They pay the buyer face value in exchange for the underlying securities or the cash equivalent should a borrower fail to adhere to its debt agreements.

Bond sales by developers rated at least BB, or one to three levels below investment grade, may rise 10-fold to more than $15 billion, Todd Schubert, a Singapore-based credit analyst at Deutsche Bank AG, said in a Dec. 7 report. Developers issued $1.4 billion of dollar-denominated debt in 2007, compared with about $5.5 billion from their U.S. counterparts, according to data compiled by Bloomberg.

`Window of Opportunity'

``Each company knows that the window of opportunity is small and they want to be the one to fit through the window,'' Schubert said in the report.

Agile pulled a $400 million debt sale in November after its borrowing costs surged to a record. The spread on the company's $400 million of 9 percent debentures due September 2013 widened to 7.17 percentage points from 3.23 percentage points on July 2. That caused the value of the bonds to fall 10 percent.

The premium on $250 million of 5.75 percent notes maturing February 2014 by KB Home, the fifth-largest U.S. homebuilder, rose to 5.38 percentage points from 2.41 percentage points, representing a loss of 5.9 percent. Agile and KB are rated BB by S&P.

After reaching a peak of 1.389 million in July 2005, sales of new homes in the U.S. fell to an annual pace of 647,000 in November, a 12-year low, as discounts failed to lure buyers and mounting foreclosures swelled the glut of unsold properties, according to the Commerce Department.

Higher borrowing costs haven't stopped developers betting China's economy, which expanded 11.5 percent in the quarter ended September from a year earlier, will continue to support the housing market.

`Huge' Demand

``Demand in China is huge,'' said Met Luk, a deputy general manager of Agile. ``Together with improvement in the economy, a lot of people are looking for a better living environment.''

Agile said it will add at least 2 million square meters (21.5 million square feet) of land this year. Country Garden Holdings Co., based in Foshan, Guangdong, tripled its land for development to 51.9 million square meters between April and August, according to an Oct. 29 Moody's report.

Cheung Kong Holdings Ltd., the property company controlled by Li, added at least 3 million square meters in the first half of last year, more than triple the acquisitions in all of 2006, its annual report shows. Li hasn't relied on debt to fund purchases in China.

`Good Year'

``2008 will be a good year for investing in the property market in China,'' Justin Chiu, executive director of Cheung Kong, Hong Kong's second-biggest developer by market value, said in an e-mail.

China real estate investments by Cheung Kong and Hutchison Whampoa Ltd., Li's largest company, were at a ``historic high'' of more than HK$10 billion ($1.3 billion), and ``would rise,'' Li said in 2006. His net worth is estimated at $23 billion by Forbes magazine.

The 79-year-old has a history of overcoming long odds to succeed. Li closed an unprofitable U.K. mobile phone operator called Rabbit in 1993. He returned a year later to start Orange Plc, which he sold in 1999 at a $15 billion profit.

Developers such as Cheung Kong and Sun Hung Kai Properties Ltd., Hong Kong's biggest, ``have been relatively prudent,'' said Hugh Young, a managing director at Aberdeen Asset Management Asia Ltd. in Singapore who oversees $50 billion. ``I don't think they just close their eyes and plunge all their money in China.''

Too Optimistic

Bondholders, wary that developers are too optimistic, say what happened in the U.S. last year and Japan in the 1990s may be repeated in China.

More than 100 U.S. mortgage lenders were shuttered, scaled back or sold in 2007 as the rate of foreclosures rose to the highest on record and home sales tumbled, according to data compiled by Bloomberg. In 1998, the Japanese government had to put 13.4 trillion yen ($122 billion) into public works as the fallout from a real estate slump lingered.

In China, a housing slump may trigger more defaults because banking laws are still being written and a consumer credit rating system doesn't exist, said Yi Xianrong, a finance specialist at the government-backed Chinese Academy of Social Sciences research institute in Beijing.

China's National Audit Office said in June it uncovered irregularities involving 15.6 billion yuan of loans in the 2005 results of three of the nation's largest banks.

``We will not know how big this problem is as long as property prices continue to rise,'' Yi said.
