RBI allows banks to invest in unrated infra bonds within 10% cap

No longer current — withdrawn, no replacement on file yet

Quick answerRBI now permits banks to invest in unrated bonds of infrastructure companies, but only within the existing 10% ceiling for unlisted non-SLR securities. This aims to boost credit flow to infrastructure without relaxing overall unlisted investment limits.
The rule, in the simplest words
How it plays out — a real example

Rohan, a treasury officer at a Mumbai bank, reviews his unlisted bond holdings on March 31 and finds he has 8% of his portfolio in such securities. He decides to purchase an unrated bond from a highway‑construction company, ensuring the new purchase keeps the total under the 10% limit. This allows the bank to support a major infrastructure project while staying within RBI rules.

What changed

Earlier, banks were barred from investing in unrated non-SLR securities. This circular carves out an exception: unrated bonds issued by companies engaged in infrastructure activities are now allowed, provided they fall within the 10% limit on total investment in unlisted non-SLR securities as of March 31 of the previous year.

What it means for you

Banks can now tap into unrated infrastructure bonds to support long-term projects, but the overall unlisted non-SLR exposure remains capped. This gives lenders more flexibility to finance infrastructure without breaching prudential norms. However, credit risk assessment becomes critical since these bonds are unrated.

Historical instruction — do not use for current compliance. This is what was required at the time; it no longer reflects current RBI requirements. If no replacement rule is linked above, that only means none is recorded on our register yet — it does not prove no later applicable rule exists. Confirm on the official RBI source below.

What banks were required to do at the time

Who it affects

❓ Common questions

Does this circular remove the ban on unrated non-SLR securities entirely?

No. The ban on unrated non-SLR securities remains, except for bonds of companies engaged in infrastructure activities. Those are now permitted, but only within the existing 10% ceiling for unlisted non-SLR securities.

How is the 10% limit calculated for unlisted non-SLR securities?

The limit is 10% of the bank's total investment in non-SLR securities as on March 31 of the previous financial year. Unrated infrastructure bonds count toward this ceiling.

Are there any additional reporting or approval requirements for these investments?

The circular does not specify new reporting or approval steps beyond existing norms. However, banks must ensure compliance with the overall prudential framework for investment portfolio classification and valuation.
