Survey: Vietnam Has One of Highest Rates of Consumer Savings VOA News Vietnamese savings are reaching new highs, but observers disagree about whether saving so much is a good sign. Market research company Nielsen found in a survey last month that Vietnam has one of the world's highest rates of consumer savings, with 69% of Vietnamese surveyed saying they put spare cash into savings, compared with 68% in Hong Kong, 66% in China, and 62% in Indonesia. As a developing nation, Vietnam is becoming increasingly wealthy, and citizens are saving more, joining a global trend of increased savings. Although saving seems good for individuals, observers, from Deutsche Bank strategist Binky Chadha to former U.S. Federal Reserve chair Ben S. Bernanke, have worried there is a surplus in savings in the world economy, which can distort the broader investment environment and lead to negative interest rates-- meaning retirees must pay to keep their savings in a bank. 'An asset bubble' In the U.S. for instance, the excess savings have pushed the stock market to record highs, which analysts say is approaching a bubble. In Vietnam, the excess savings has also fed an asset bubble, particularly in real estate. Vietnam's economy is growing quickly but experts disagree on how to interpret the wealth that it is generating. On the one hand, there may not be enough productive investments available, so savers are investing in luxury real estate that is feeding a bubble, according to a research note by Oxford Analytica. On the other hand, being able to set aside so much money is a positive sign from consumers, according to Nielsen Vietnam. "As more and more people feel confident about their future, despite better job security, they are putting away more for a rainy day rather than spending today," Louise Hawley, managing director at Nielsen Vietnam, said. "This also suggests optimism in what tomorrow will bring." A sign of anxiety? However the high savings rate could also be interpreted as a sign of anxiety, as people worry they will need the money for retirement. "One of the main reasons why Vietnamese people have to save is because there is no social security network," a commenter wrote in the local newspaper Thanh Nien. This means Vietnam is part of a global trend identified by Chadha. He noticed that savings rates are going up, even though interest rates are going down, sometimes to negative rates, so people are not saving money to earn interest. Instead Chadha sees this as a sign that people are saving because they fear they will not have enough funds in the future. Vietnam's savings rate is not an isolated issue. Bernanke argued that Asia, particularly China, has earned so much from exports that the money has contributed to a "global savings glut." More recently Vietnam has also become one of the developing Asia nations with high exports and, therefore, a current account surplus. .
