The Indian rupee crashed by 73 paise to close at two-month low of 62.66 against the US currency on on strong dollar buying by banks and importers.
Forex dealers said weakness in local equities cast a shadow on the rupee. Dollar losing in overseas markets didn't impact the fall of the local currency, they added.
