BEIJING/HONG KONG, Nov 18 (Reuters) - A slew of recent supportive measures will bring China's cash-strapped property developers much needed relief, but a full recovery of the sector will be hobbled by increasingly elusive buyers, say bankers, developers and analysts. "These policies will have little lasting effect and the property prices will not go up significantly," said Jack Yang, an engineer in Beijing, noting "future income" had become a key concern for homebuyers. Despite the recent liquidity-boosting measures, some bankers say developers continue to face credit risks given the uncertain outlook. According to UBS, Chinese banks have roughly 88 trillion yuan ($12.43 trillion) worth of exposure to the property sector. It estimates the property sector downturn will cost the banking system up to 1.4-1.5 trillion yuan in the next few years, mainly from potential losses in banks' unsecured property development loans, bonds, and non-standard assets.
