The rupee weakened in the second half of the trading session to close flat at 55.53 as domestic markets weakened.
The local unit opened stronger at 55.43. On Friday, the rupee had closed at 55.53.
The rupee took positive cues from the US Federal Reserve Chief’s assurance that it will do all that is possible to support the US economy. A similar assurance by several Euro Zone members has also strengthened the euro against the dollar.

A depreciating currency is considered detrimental to an import dependent country like India, because the country has to pay more rupees for each dollar of product (like oil) imported.
