NEW YORK – Recent market volatility – in emerging and developed economies alike – is showing once again how badly ratings agencies and investors can err in assessing countries’ economic and financial vulnerabilities. Ratings agencies wait too long to spot risks and downgrade countries, while investors behave like herds, often ignoring the build-up of risk for too long, before shifting gears abruptly and causing exaggerated market swings.
纽约—最近的市场波动——新兴市场和发达经济体都一样——再一次证明，评级机构和投资者在评估各国经济和金融脆弱性时会犯下极其严重的错误。评级机构需要太长的时间认识风险、调降国家评级，而投资者的行为就像是羊群，常常在太长的时间里忽视风险的累积，然后突然转变方向，导致市场波动放大。
