"The amount of notes issued may not exceed the equivalent of 50 tonnes of gold in the first year, and the lower limit for the nominal interest rate may be 2%," the gov- ernment said Imports of the metal climbed 10.5% in May from a year earlier to $2.42 billion. The rupee, down about 1% this year, weakened 0.1% to 63.8187 a dollar as of 1.34 p.m. in Mumbai. The record low in 2013 was 68.845.
