Kotak Bank profit up 26%, but margin worry looms

Why did Kotak Mahindra Bank's stock fall despite 26% profit growth?

Kotak's stock fell on Friday, October 23, before results were out, closing 1.49% lower at Rs 430.50. Markets price expectations, not past numbers. Traders already knew costly foreign-currency deposits from the RBI's (Reserve Bank of India) FCNR(B) swap window were squeezing margins. They wanted to see if that pressure was temporary, not just a strong headline.

Why did every big private bank's margin fall this quarter?

All four large private banks (HDFC, ICICI, Axis and Kotak) saw margins shrink because they raised costly FCNR(B) foreign-currency deposits through an RBI swap window. These deposits cost more than savings accounts, inflating deposit growth while diluting net interest margins. Nomura expects the squeeze to hit every bank, though the pain varies: Kotak loses 5 basis points, Axis 7, ICICI 10.

How much margin pressure can the bank absorb before it really hurts?

Nomura expects Kotak's net interest margin to fall 5 basis points in Q2FY27, roughly Rs 400 crore of net interest income at current asset levels. But profit still grew because loan growth held at 21% and the bank cut one-to-three-year deposit rates by 15-25 basis points, lowering its own funding costs. Credit costs stay benign at 40-65 basis points for large private banks. Our read: the margin hit is a rounding error next to loan growth and lower deposit costs, unless loan demand weakens, which nothing in the evidence suggests.

Why does a mere ratio problem still make the stock fall?

The stock fell before results because investors fear the FCNR(B) squeeze is not over. The RBI raised the repo rate to 5.50% on October 7, which affects margins from Q3, meaning the pressure could continue beyond this quarter. Also, Nomura says return on assets will decline 3-8 basis points as assets expand faster than profits, so earnings growth slows even if profit stays positive. Our read: the market is pricing the next quarter, not this one, and the rate hike makes the margin story look structural, not temporary.

What would it take for the margin pressure to actually hurt earnings?

The margin squeeze becomes an earnings problem only if loan growth stalls, since the 5-basis-point NIM hit equals roughly Rs 400 crore at current assets, a fraction of the Rs 5,645 crore profit. Nomura expects loans excluding FCNR(B) to still rise 14-23% year on year and credit costs to stay at 40-65 basis points. Our read: the bank has room to absorb this, so the real risk is a slowdown in credit demand, not the margin itself.

What would make the margin squeeze spill into actual losses?

The squeeze only becomes an earnings problem if credit costs spike or loan growth collapses. Nomura expects credit costs to stay benign at 40-65 basis points for large private banks, cushions like Kotak's 22.4% capital adequacy ratio and Rs 1,94,706 crore net worth provide ample buffer. A Republic of India rate hike to 5.50% raises funding costs but the bank has already cut term-deposit rates. Our read: only a sharp economic downturn or a jump in defaults, both absent from the evidence, could turn this ratio squeeze into real losses for Kotak.

If the margin squeeze is absorbed, what actually limits the bank's growth?

That limit is capital, and Kotak has plenty. Its capital adequacy ratio stands at 22.4% and its common equity tier-1 ratio at 22.1%, well above regulatory minimums, against a net worth of Rs 1,94,706 crore. With return on assets at 2.10%, the bank can keep lending without raising fresh equity. Our read: the binding constraint is not capital but loan demand, and nothing in the evidence shows that weakening.

Can Kotak keep growing even as margins shrink?

Nomura, a research firm, thinks yes. Excluding FCNR(B)-linked loans, large private banks' loan growth should still rise 14-23% year on year, and Kotak has cut 15-25 basis points off one-to-three-year term deposit rates. FCNR(B) deposits run 3-10% of private bank deposits, and banks used the liquidity to retire high-cost deposits. Our read: margin pressure is a ratio problem, not an earnings problem, if loan demand holds.

What is FCNR(B) and why did it squeeze Kotak's margins?

FCNR(B) deposits are foreign-currency deposits from non-resident Indians. In Q2, the RBI (Reserve Bank of India) offered a swap window that encouraged banks to raise them. These deposits cost banks more than savings accounts, so they inflated deposit growth but squeezed net interest margins. Kotak's margin is expected to shrink by 5 basis points quarter on quarter.

What happens when the FCNR(B) deposits start to run off?

The foreign-currency deposits were raised through an RBI swap window in Q2, and they now account for 3-10% of private bank deposits. Banks used that liquidity to retire high-cost bulk deposits and certificates of deposit, so the funding mix is cleaner going into the second half. Nomura calls this a cost-of-funds tailwind, meaning the run-off itself is not the risk. The RBI also raised the repo rate to 5.50% on October 7, and that affects margins from Q3 onward. Our read: the real test is whether cheap domestic deposits replace the FCNR(B) money without pushing rates back up, not the run-off itself.

What would make the market change its mind on the stock?

The market is pricing in slower growth because margins are squeezed and analyst targets were set before results. Kotak's capital position is strong, with a Common Equity Tier 1 ratio of 22.1% and a liquidity coverage ratio of 137.4%, leaving room to lend. Nomura expects credit costs to stay benign at 40-65 basis points for large private banks. Our read: the stock moves when quarterly results show margins stabilising and loan growth staying in the high teens, likely from Q3 when the FCNR(B) overhang fades and repo hike effects are absorbed.

How much growth would the bank have to give up to protect its margin?

The trade-off is visible in the numbers. Nomura expects return on assets to fall 3-8 basis points quarter on quarter at Kotak because assets expand faster than profits, even as loan growth holds at 14-23% excluding FCNR(B) loans. Kotak's consolidated ROA is 2.10%, so it is starting from a strong base. The bank has already cut one-to-three-year deposit rates by 15-25 basis points, which feeds margins with a lag. Our read: the bank can absorb the margin dilution because credit costs stay benign at 40-65 basis points, so protecting the ratio matters less than keeping loan momentum.

What stops the bank from letting margins fall further to chase growth?

The constraint is return on equity, not capital. Kotak's annualised ROE for Q2FY27 stood at 11.70%, while its consolidated capital adequacy is 22.4%, far above regulatory minimums. Nomura expects ROA to fall 3-8 basis points quarter on quarter as assets grow faster than profits, and credit costs are expected to stay benign at 40-65 basis points. If margins keep eroding while loans grow, ROE falls, which pressures the stock's valuation multiple. Our read: Kotak is near the edge where the growth-for-margin trade stops paying for shareholders.

What would force the bank to choose margin over growth?

Nomura expects credit costs to stay benign at 40-65 basis points for large private banks, and Kotak's gross NPA is the lowest among peers at 1.04%. If credit costs stayed at those levels while loan growth holds at 14-23%, the growth-for-margin trade remains viable. A rise in defaults, a reversal in deposit rate cuts, or a bigger repo rate pass-through would change that arithmetic by pushing ROA down faster than the 3-8 basis points currently expected. Our read: the trigger would be deteriorating asset quality, not margin dilution itself, because that is the one variable that feeds straight into earnings.

What is the one number that sets the floor for how far margins can fall?

The floor is return on equity. Kotak's annualised ROE for Q2FY27 is 11.70%, while its capital adequacy of 22.4% is nearly three times the regulatory minimum. If margins keep eroding, ROE drops, and the stock's price-to-earnings multiple of 26.69 compresses further. Nomura expects credit costs to stay benign at 40-65 basis points, which is the only reason the trade still works. Our read: ROE below 10% would break the investment case, not a specific margin number.

Why is a 26% profit jump not moving the stock?

Kotak's shares closed at Rs 430.50 on October 23, down 1.49%, and the stock is down 2.94% for the year. Analyst targets, set before results, range from Rs 509 to Rs 520, with a consensus near Rs 476. The market is pricing in the margin squeeze that follows the FCNR(B) deposit wave, and the RBI's October 7 repo hike to 5.50% will press margins further from Q3. Every large private bank saw its margin fall this quarter, so the profit beat is read as partly borrowed from future quarters. Our read: the stock market is looking past this quarter's earnings to the slower growth the margin pressure implies.

Can Kotak keep lending aggressively without hurting returns?

Kotak's capital adequacy is 22.4% and its liquidity coverage ratio is 137.4%, so it can lend without raising equity capital. However, Nomura expects return on assets to decline 3-8 basis points quarter on quarter as assets expand faster than profits. Loan growth of 14-23% year on year at large private banks is tied to FCNR(B)-linked loans that dilute margins. Our read: the bank is choosing growth over margin, and that trade-off is sustainable as long as credit costs stay benign and deposit rates fall further.

Is 5 basis points of margin compression a lot?

Not in absolute terms. A basis point is one-hundredth of a percentage point, so 5 basis points is tiny. What matters is the direction: Nomura expects Kotak's net interest margin, the spread between what it pays for deposits and earns on loans, to shrink by that amount this quarter because of costly FCNR(B) foreign-currency deposits. And the RBI's (Reserve Bank of India) October 7 repo rate hike to 5.50% will press margins further next quarter.
