Priority Sector LendingPSL
RBI's mandate to lend a set share of credit to agriculture, MSME, and other priority sectors.
Why you care
A bank doesn't get to lend wherever margins are fattest. RBI mandates that 40% of adjusted net bank credit go to priority sectors — agriculture, MSME, housing, education, weaker sections. It's a standing claim on where a big chunk of the loan book must point, whatever the bank would otherwise choose.
Run the numbers
On ₹1,00,000 cr of adjusted net bank credit, ~₹40,000 cr must be priority sector (illustrative target), with sub-targets like ~18% to agriculture. Miss it and the shortfall goes into low-yield RIDF deposits — a soft penalty that stings.
Where this goes
PSL directs a large share of credit growth and shapes the yield on advances. Some priority loans are thin-margin (farm credit), others high-yield (microfinance), so the mandate quietly moves the blended yield either way.
Why you care
Priority Sector Lending (PSL) is RBI's rule that a set share of a bank's credit must flow to sectors the state considers under-served. That list includes agriculture, micro/small/medium enterprises, affordable housing, education, renewable energy, and weaker sections. For most banks the target is 40% of Adjusted Net Bank Credit (ANBC).
This is the clearest example on the map of the regulator overriding pure profit-seeking. Left alone, a bank would lend wherever the risk-adjusted return is best. PSL says: no, a large slice must go where policy wants it, whether or not that's where the margins are. For anyone in credit or branch banking, PSL explains a lot of otherwise-puzzling behaviour — why there's a farm-loan or MSME target on your desk. It also explains why the bank scrambles at year-end to buy its way to compliance, and why some lending happens that the pure economics wouldn't justify.
The compliance details are worth knowing:
- Sub-targets: within the 40%, there are floors — roughly 18% to agriculture, with carve-outs for small and marginal farmers and weaker sections.
- PSL Certificates (PSLCs): a bank that over-lends to priority sectors can sell the excess as a tradable certificate to a bank that has fallen short. This created a real market where compliance itself is bought and sold, without the underlying loan changing hands.
- Shortfall penalty: a bank that misses the target must park the gap in low-yielding rural funds (RIDF with NABARD) — not a fine, but a drag that makes falling short genuinely costly.
Run the numbers
A bank with ₹1,00,000 cr of ANBC (illustrative):
- Priority sector requirement: 40% → ₹40,000 cr must be priority-sector loans.
- Of that, roughly 18% of ANBC (₹18,000 cr) to agriculture, with further floors inside it.
Now the yield twist. Suppose the bank would earn ~10% lending freely, but its farm-credit PSL earns only ~8.5% while its microfinance PSL earns ~20%. The mandate doesn't just cap where money goes — it reshapes the yield on advances. A bank that meets PSL through low-margin agriculture drags its blended yield down; one that meets it through high-yield microfinance can actually lift yield, but takes on more risk. So PSL is not simply a cost — it's a set of constraints a smart treasury works with, using PSLCs and product mix to hit the target at the least damage to margin.
Where this goes
PSL is a standing claim on the loan book: it steers a large share of credit growth into mandated sectors. By fixing that mix, it also moves the yield on advances up or down, depending on how the bank chooses to comply. It's the regulator's grip reaching past how much a bank lends into who it must lend to — the last of the constraints that shape the spread before it even begins.
