The rupee, alongside other emerging market currencies, has had a few turbulent days. Following an extraordinary attack by Turkey’s president, Recep Tayyip Erdogan, on the US and global financial markets, the Turkish currency, the lira, took a special battering. Its fall has been the highest since 2001; in just a few months it has gone from about four lira to the dollar to around seven. Mr Erdogan’s open defiance of the financial markets came at a time when the US appeared unwilling to provide stability, with US President Donald Trump announcing on Twitter that tariffs on Turkish steel would, in fact, be increased. As a consequence, concern rippled through emerging markets — sending the rupee, in particular, to its lowest value against the dollar. It is now perilously close to 70 to the dollar. It is important to note that this development is not without its advantages. As long as there is no excess volatility in the foreign exchange market — an outcome which is the Reserve Bank of India’s (RBI’s) job to ensure through timely intervention — a certain weakness of the rupee is the need of the hour.
