New notes are issued by the Reserve Bank of India (RBI)’s department of currency management.
It gets the notes from four presses. The Security Printing and Minting Corporation of India (SPMCIL) has presses at Nashik in Maharashtra and Dewas in Madhya Pradesh. The other two are owned by RBI, through a subsidiary, Bharatiya Reserve Bank Note Mudran (BRBNML), at Mysuru, Karnataka, and Salboni in Bengal.
Printing cost varies. That for a Rs 1,000 note at BRBNML is Rs 2.67 each; in SPMCIL, Rs 3.15. The cost of printing Rs 100 notes in these is Rs 1.20 and Rs 1.41 apiece, respectively.
Coins are made at four government-owned mints — at Mumbai, Hyderabad, Kolkata and Noida.
When the denomination of the notes rises, the cost to the face value dips. For example, it is cost-effective to print a Rs 1,000 note at Rs 3.15, instead of printing ten Rs 100 notes and incurring Rs 14.1 for the same value.
The RBI Act allows the central bank to publish notes of up to Rs 5,000 and Rs 10,000 denominations but not more. The government has to approve before those notes are introduced. The highest denomination note printed were Rs 10,000 ones, in 1938 and in 1954. These were demonetised in 1946 and again in 1978.
Notes received back from circulation are examined and those not fit for reissue are destroyed. Coins do not come back from circulation, except those which are withdrawn. RBI disposed 16.4 bn of soiled notes and issued fresh ones against these in 2015-16. It did not disclose the cost.
While a soiled bank note can be exchanged for full value, a mutilated note can be exchanged for full value or half, depending on the degree of mutilation. The cost of sorting these is not known.
RBI indicates the volume and value of banknotes to be printed each year, based on demand.
The average age of the notes are usually less than a year but depend on usage. Lower the value, higher the usage. For example, a Rs 10 note could last no more than eight to 10 months, whereas a Rs 1,000 note could remain fresh for a long time, as these tend to be stored and used carefully.
The currency paper is composed of cotton and cotton rag. The papers are now largely made in India.
