The Centre said a special window can be provided to the states, in consultation with the RBI, for borrowing at a reasonable interest rate.
economists said even though the Centre has given the states the option to borrow as much as Rs 2.35 trillion, Article 293 (3) of the Constitution imposes certain restrictions on the borrowings by state governments.
"The Article stipulates that a State may not, without the consent of the Government of India, raise any borrowings if it has any loan outstanding, which is repayable to the Government of India. Furthermore, under the Constitution, State Governments, unlike the Centre, cannot borrow externally," they said in a note.
Elaborating on their options, the economists said the option of RBI monetising the debt can be availed because the central bank is a banker to all state governments.
However, they said monetisation of state debt is not exactly possible in the current circumstances and it is better if the Centre monetises the debt and gives to states.
The RBI too will be comfortable in dealing with the Centre rather than close to 30 sub-national entities, the note said.
Debt monetisation refers to purchase of government bonds by the central bank.
On enlargement of the WMA -- a facility for both the Centre and states to borrow from the RBI -- it said this can be a short-term measure as WMA is to be liquidated within 90 days' specified period.
Taking recourse to NSSF, the third option, is akin to launching a Special Purpose Vehicle (SPV) providing an autonomous source of finance for the governments.
"It mobilises small savings through post offices and banks and used to lend against non-tradable securities issued by the States till it was discontinued in FY2017 as the special securities carried a rate of interest of 9.5 per cent that was considered too high by states," it said.
The states can be again allowed to tap NSSF
at a concessional rate of interest so that their reliance on open market borrowings is reduced, it added.
