Malaysia's debt to GDP ratio increased to 242% in mid-2012 from 192% in 2008 according to McKinsey. As export growth has slowed the Malaysian government is relying on credit expansion to consumers and large capital projects such as the planned subway project in Kuala Lumpur to sustain growth. Similiar credit expansion is seen in other Asian countries- Thailand, Vietnam, Singapore, Hong Kong. The period 2008 to 2013 has seen a rapid acceleration in credit expansion in these countries and especially in China. China's debt to GDP ratio increased to 183% in mid 2012 from 153% in 2008, according to McKinsey. Nomura Holding's economist Zhiwei Zhang, and other economists say it is above 200% when government data on "shadow banking" lending institutions such as trust companies is included. IMF economist Giovanni Dell'Ariccia has studied of debt expansion and credit booms since the 1970's. He and other economists at the IMF have found that credit booms- the rapid increase in credit to GDP ratios- end up in crises one third of the time, result in below par growth in another third of the time, and only in one third of the time does growth continue at the high pace. Alex Frangos talks to government officials in Kuala Lumpur who do not take seriously the high vacancy rate for office buildings in the capital of about 20% even as new office towers are being built. Bob Davis gives the example of government owned Hunan Expressway company in China which has a huge road building program and doubled its 2009 debt levels. Another state owned company in shipping China Cosco Holdings increased total debt from 85 billion yuan in 2009 to 123 billion yuan in 2012. As export growth slowed in China in 2009 credit expansion is driving growth. The normal restraints of the market are absent in China's state owned companies. Charlene Chu, senior director of Fitch Ratings Inc in Beijing, says 2012 demonstrated that the Chinese government cannot slow credit growth without risking a decline in growth. China's GDP growth in the 1st quarter of 2013 slowed to 7.7% from 7.9% in the 4th quarter of 2012. This poses a serious problem for China. China has never experienced the kinds of problems seen in Asia after the 1997 banking crisis, in the eurozone today, and in the U.S. following the financial crisis of 2008, making government officials prone to complacency about the risks....
