A senior banker familiar with the developments said "letter of credit or some form of bank guarantees can be given, so that trade settlement is not hampered. We are looking into it".
The finance ministry and Reserve Bank of India did not immediately reply to requests for comment.
The government is also looking at having state-owned banks lend to exporters at reduced rates or provide funds to them directly up to the amount of pending payments from Russia and Ukraine.
The official said the decisions could be taken in a couple of weeks.
The banking source said then the central bank could follow up and "find solutions to how bilateral trades can be settled." India exported $3.33 billion worth of goods to Russia in 2021, mainly pharmaceutical products, tea and coffee, while imports totalled $6.9 billion, including defence goods, mineral resources, fertilizers, metals and precious stones.
