ICICI Bank profit up 20%, but lending margin slips

Are HDFC Bank's slow profit growth and new CEO connected?

The modest 4.7% profit growth came from a squeezed lending margin (net interest margin fell to 3.16% from 3.27% a year earlier) as HDFC Bank pulled in 11.5 billion dollars of foreign-currency deposits that it has yet to fully deploy. That margin pressure is separate from the succession issue, which saw the board submit two CEO names to the RBI (India's central bank) on September 12.

Why would a bank want foreign-currency deposits it can't lend out yet?

The RBI swap window (a central bank program letting banks hedge currency risk) let banks hedge currency risk for free, saving 280-300 basis points a year on hedging costs. That made FCNR(B) deposits (foreign-currency deposits from non-residents) cheap enough to compete with US Treasuries. But the money arrived faster than loans could absorb it, so banks paid interest on idle funds, squeezing margins until deployment catches up. The window closed September 30.

Who bears the cost if the rupee moves against the dollar?

The RBI swap covers only the deposit principal at the same exchange rate at maturity, saving banks 280-300 basis points a year in hedging costs. The bank still has to hedge the interest it pays on the deposit, adding 15-20 basis points to the effective cost. If the rupee depreciates sharply, the RBI, not the bank, absorbs the principal loss. But the bank's margin is already squeezed while funds sit idle, and the interest hedge is the bank's own bill.

What exactly caps how much the bank could offer depositors once the swap erased hedging costs?

The ceiling is the RBI's interest rate rules, not the market. For FCNR(B) deposits, fixed-rate interest is capped at the applicable LIBOR rate for the deposit's currency and maturity plus 200 or 300 basis points. The concessional swap removes the 280-300 basis point hedging expense, so banks could afford to price nearer that ceiling to attract dollars. But the rate is locked at booking, so the bank's cost is fixed even if deployment stalls.

Could banks have offered even more than the cap allowed once the swap cut hedging costs?

No. The RBI cap is a ceiling, not a target. The fixed-rate ceiling is LIBOR plus 200 or 300 basis points for the currency and tenor. Banks can price at or below that level. The swap removes 280-300 basis points of hedging cost, which improves the bank's ability to pay more, but the cap itself is not changed by the swap. So the cap sets the maximum, but market competition and deployment plans determine what banks actually offer.

Who really bears the risk if the rupee crashes before these deposits mature?

The RBI bears the principal risk through the at-par swap, returning dollars at the same rate at maturity regardless of the rupee's movement. The bank only hedges the interest component separately, at 15-20 basis points. But the swap is non-cancellable once executed, so the bank is locked into paying depositors for 3-5 years even if rupee conditions shift. Our read: the RBI's concession is a deliberate bet that stronger reserves justify the currency risk it absorbs to pull in dollars quickly.

Who actually benefits from the RBI's cheaper dollar deposits?

The RBI absorbs the principal currency risk, and banks get a cheaper, longer-term funding source. The depositor gets a rate that can now compete with US Treasuries, but the real winner may be the bank's cost of funds. This liquidity let banks cut three-month certificate of deposit rates by 130 basis points, which offsets the initial margin drag and helps them retire costlier wholesale borrowings. Our read: the scheme is a balance-of-payments tool first, and a cheap funding source for banks second.

Why would the RBI absorb currency risk instead of letting banks hedge it themselves?

The RBI needed dollars quickly and cheaply. The rupee had fallen about 7% year to date and reserves dropped from $728 billion to $682 billion, while FII outflows and West Asia crude above $100 a barrel added pressure. A 280-300 basis point hedging cost made FCNR(B) deposits uncompetitive against US Treasuries. By absorbing the principal currency risk itself, the RBI removed that cost and pulled in dollars fast. Our read: the RBI judged a stronger reserve buffer worth taking the currency risk on its own books.

What decides whether bank margins recover or stay squeezed?

The banks' own forecasts say margins bottomed last quarter and should improve from Q3 onwards. Two things decide that: whether the 25-basis-point repo hike (a central bank rate increase) lifts lending rates before year-end, and how quickly they deploy the FCNR(B) billions (foreign-currency deposits) into loans. The RBI's liquidity absorption also matters, it has already pulled back nearly $20 billion equivalent.

Why would a cheaper dollar deposit still squeeze margins?

Because the swap covers only the principal, not the interest the bank must pay on the deposit. Banks hedge that interest separately, adding 15-20 basis points to the effective cost. And the deposit is not instantly deployed into loans; while it sits idle, the bank pays out interest at the depositor rate without earning a lending yield, dragging the net interest margin down until the funds are matched to loans.

Why did HDFC Bank profit grow slower than lending income?

HDFC Bank's profit grew only 4.7% because its net interest margin, the spread between what it earns on loans and pays on deposits, narrowed to 3.16% from 3.27% a year earlier. The bank earned more from lending overall, but less on each rupee lent, so profit rose slower.

Why does the bank expect margins to recover after Q3?

Margins recover because the funds stop being idle and start earning. The FCNR(B) deposits arrived faster than they could be lent out, so banks paid interest on unproductive cash, dragging down NIMs. Over the next two quarters, the money gets deployed into loans, and the RBI's 25-basis-point repo hike lifts lending yields. "Our read: the recovery is arithmetic, not a bet on demand; the question is whether loan growth absorbs the surplus fast enough."

What would make the bank's arithmetic margin recovery stall?

The recovery depends on two things: deploying the FCNR(B) money and repricing loans. The RBI has already absorbed nearly $20 billion equivalent of the extra liquidity, which shrinks what banks can lend out. If loan growth cannot absorb the surplus fast enough, the money sits in low-yielding assets and the drag continues. Hedge costs on the interest component add 15 to 20 basis points on top. Our read: the risk is a slower deployment, not a rates reversal.

Who loses if the bank's deployment plan fails?

The banks themselves carry the loss, but the mechanism is shared. ICICI raised $17.88 billion in FCNR(B) deposits; HDFC raised $11.5 billion. If those funds sit idle, the banks pay interest on unproductive cash, which is the drag on NIM. The RBI also loses some control, since it has already absorbed nearly $20 billion of liquidity to manage the surplus. Depositors are protected by fixed rates locked at booking. Our read: shareholders absorb the cost through lower returns, not depositors or the RBI.

Why does the RBI's swap expose banks to interest-rate risk?

The RBI's concessional swap covers only the deposit principal, not the interest the bank must pay the depositor. Banks have to hedge that interest liability separately, adding 15 to 20 basis points to the effective cost of FCNR(B) deposits, as Macquarie noted. The hedge cost is set at booking and cannot change, so if interest rates move, the bank absorbs the gap. Our read: the RBI shifted currency risk to itself but left rate risk with the banks, which is why the rate cycle matters.

What protects depositors if a bank that took FCNR(B) money fails?

The RBI's swap window does not guarantee deposits; it only eliminates the bank's currency hedging cost on the principal. FCNR(B) deposits are ordinary bank liabilities, protected by the same deposit insurance framework as domestic deposits, which covers up to ₹5 lakh per depositor per bank. The one-year lock-in and fixed rates at booking protect the depositor from market moves, not from bank failure. Our read: the RBI's exposure is currency risk and system liquidity, not credit risk on individual banks.

What happens if the RBI keeps absorbing the liquidity the deposits brought in?

The RBI has already pulled nearly $20 billion equivalent of rupee liquidity out of the system through forex operations, bond sales and reverse repos, which shrinks what banks can lend from the FCNR(B) surplus. That lowers the amount available for deployment, so the margin drag from idle funds lasts longer than banks hope. Banks like ICICI, which raised $17.88 billion, and HDFC, with $11.5 billion, must find loan demand for a smaller deployable pool. Our read: the RBI is mopping up precisely to cap the surplus, so banks cannot count on the full inflow earning loan yields anytime soon.

Why did HDFC Bank's interest spread narrow?

HDFC Bank's net interest margin (NIM), the spread between what it earns on loans and pays on deposits, narrowed to 3.16% in the September quarter, from about 3.27% a year earlier. The squeeze came from the Reserve Bank of India's special window (a temporary program) that pulled in $11.5 billion of FCNR(B) deposits (foreign-currency deposits from non-residents), which banks hadn't yet deployed into loans.

What happens to the money the banks can't lend out yet?

The RBI has already started absorbing the surplus. By September 29, its operations had removed nearly $20 billion equivalent of rupee liquidity from the system, cutting into the amount available for deployment. Banks have also used part of the funds to repay expensive wholesale deposits, which helped three-month certificate of deposit rates fall from 7.16% to 5.86%. The rest sits in low-yielding securities until loans catch up, which is why margins stay squeezed for now.

What stops banks from lending the FCNR money faster?

Banks cannot speed up deployment because the RBI has been pulling liquidity back out of the system. By September 29, RBI operations had removed nearly $20 billion equivalent of rupees, which funds loans. ICICI Bank has also already extended $9 billion in overseas loans against its $17.88 billion haul and issued $3.63 billion in standby letters of credit, using the funds to replace costlier deposits instead of aggressive new lending. The remaining cash sits in low-yielding securities until credit demand and a higher repo rate make lending more profitable. Our read: the cap is credit demand, not willingness; banks deploy as fast as borrowers appear.

What happens to the FCNR money after the swap window closes?

The window closed September 30, but the deposits are locked in for three to five years. ICICI Bank has already used $9 billion of its $17.88 billion to fund overseas loans and issued $3.63 billion in standby letters of credit, with the rest to be deployed over the next two quarters. Because the principal is swapped at par, the bank's currency risk is zero until maturity. Our read: the real risk is the bank having to hedge the interest it pays on these deposits, at 15 to 20 basis points, which eats into the margin benefit.

What happens when these three-year deposits start maturing?

The deposits are locked in for three to five years and the principal swap with the RBI cannot be cancelled. At maturity, the bank must return dollars to depositors, and since the swap covers only the principal at the original spot rate, the bank's currency exposure on the principal is zero. However, the interest paid on these deposits, which the bank has to hedge separately at 15 to 20 basis points, remains a cost through the deposit's life. When the deposits mature, banks will need to either roll them over at prevailing rates or replace them with other funding, likely at higher costs if the rate cycle has turned. Our read: the maturity wall is manageable because banks have three to five years to plan, but the interest hedging cost is a permanent drag on the margin benefit these deposits were meant to deliver.

What happens to the banks' profit if the margin never recovers?

The margin drag is a finite cost, not a permanent loss. Banks brought in the FCNR(B) money to replace costlier wholesale funding; three-month certificate of deposit rates fell from 7.16% to 5.86%, so the funding-cost saving offsets the initial margin squeeze. Management says margins bottomed in Q2 and should improve from Q3, helped by the 25-basis-point repo hike lifting lending rates. Our read: the profit risk is not the margin itself, but how much of the idle cash earns while it waits to be deployed into loans.

Can a bank lend more than the foreign deposit it holds?

Yes, and it can lend a multiple of it. The RBI has clarified that banks can extend loans or issue standby letters of credit against FCNR(B) deposits, and can even grant loans to the depositor against a lien on the deposit. Banks are offering leverage of up to eight or nine times the deposit amount, meaning for every $100 deposited, about $80 could be a bank loan. These loans are priced at thin margins of 80-90 basis points, which is why aggressive leverage is part of the pressure on profitability. Our read: this leverage is how banks turn a deposit-raising exercise into a lending business, but it caps the margin they can earn on the money.

Who ultimately pays for the margin squeeze?

The banks themselves absorb it in the short term, but they have a cushion. The FCNR(B) funds replaced costlier short-term wholesale funding, so three-month certificate of deposit rates dropped from 7.16% to 5.86% by early September. ICICI Bank used part of its $17.88 billion haul to repay existing deposits, and Axis Bank retired high-cost non-retail term deposits. That saving offsets some of the drag on what banks earn on loans, before the funds are fully deployed in the next two quarters.
