Robert Prior-Wandesforde, head-India Economics, Credit Suisse, says it was hard to imagine an orderly exit of Greece from the euro zone. Spain has emerged as another worrying sign for the market, he says. He says the macroeconomic damage due to the Greek exit would impact the trade-dependent economies in Asia, such as Singapore, Hong Kong, Malaysia, etc. China and India, which have a bigger domestic base, will be slightly better off.
