Published by Zeb BhamForex traders looking to assess the market's attitude to risk need look no further than the Australian dollar, Forex Blog claims.The site's market analyst Adam Kritzer noted that over the last year, the Aussie has traded in "almost perfect unison" with the S&P 500, climbing on bullish trends in stocks and falling as risk aversion returns to equity markets."Since the S&P 500 is a pretty good proxy for risk it can be said that the Australian Dollar is a manifestation of investor risk appetite," he claimed.Mr Kritzer added that the fluctuations the currency has seen in recent months also offer a fairly accurate indicator of both national and international economic conditions, and the Aussie is becoming increasingly popular as traders realise this.According to the recent Bank for International Settlements' (BIS) triennial central bank survey, the Aussie is now the fifth most actively traded currency in the world, overtaking the Swiss franc.In its eagerly awaited report, the BIS also noted that the global forex trading market continued to grow over the last three years, with average daily turnover volumes standing at $4 trillion in April 2010, against $3.3 trillion three years earlier.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site.
