The IMF report notes:
- A resurgent economy, which has buoyed incomes.
- Low interest rates. Real mortgage rates have been very low or negative for the past two years, leading to high housing credit growth rates.
- Supply constraints. Housing supply has not kept pace with population growth, which has been driven up by strong immigration.
- Demand by nonresidents. A booming economy and prospects of currency appreciation, along with Singapore’s strong investment climate, have lured foreign interest in the housing market.
Staff analysis suggests that the measures undertaken by the authorities through January 2011 have helped contain prices and transaction volumes in the housing market, both of which are now moderating. Along with slower domestic growth, an uncertain outlook, and a significant supply pipeline of public and private housing projects (although residential construction activity is slowing), the housing market was already likely to cool further. The latest measures in December 2011 took markets by surprise and shifted the balance of risks further downward. Because these measures are residency˗based and focus on the housing market, they also carry some risk of pushing foreign demand over to commercial and industrial property markets (which are also experiencing price increases) or to other countries."
