The growth rate of currency in circulation slowed down to 3.7% for the week ended February 9, compared to 8.2% a year earlier, due to the Reserve Bank of India's decision to withdraw Rs 2,000 banknotes. Currency in circulation includes all notes and coins in circulation, excluding cash held by banks. Commercial banks also saw double-digit growth in deposits in January, which can be linked to the withdrawal of Rs 2,000 notes.
