Z-category banks are staring at a Tk1.63 lakh crore provisioning hole, with several lenders carrying classified loans worth more than half of their entire loan books, exposing deep cracks in their balance sheets and raising the risk of further erosion of earnings and capital.
The latest figures show Islami Bank Bangladesh, National Bank and IFIC Bank alone have combined provisioning shortfalls of nearly Tk1.28 lakh crore, while their classified loans account for 52.1 per cent, 65.7 per cent and 63.4 per cent of their respective loan books.
Islami Bank Bangladesh is facing the biggest absolute gap. Of its Tk1.90 lakh crore outstanding loans, Tk98,915 crore, or 52.1 per cent, is classified. Against a required provision of Tk89,488 crore, the bank has maintained only Tk7,154 crore, leaving an Tk82,334 crore shortfall.
National Bank is in an even worse position in terms of loan quality. Tk28,277 crore, or 65.7 per cent, of its Tk43,014 crore loan book is classified. Its required provision is Tk25,224 crore against only Tk1,898 crore maintained, leaving a Tk23,326 crore gap.
IFIC Bank has Tk28,520 crore in classified loans, or 63.4 per cent of its Tk45,000 crore portfolio. Against a required provision of Tk22,887 crore, it has set aside just Tk993 crore, resulting in a Tk21,894 crore shortfall.
The figures indicate that the problem goes far beyond a high volume of bad loans. The banks have limited loss-absorption capacity if recoveries fail to improve or fresh defaults pile up.
Premier Bank has Tk11,754 crore in classified loans, equivalent to 35 per cent of its portfolio, with a Tk11,971 crore provisioning gap. Rupali Bank has Tk19,791 crore classified loans, or 41.3 per cent of its loans, and a Tk10,754 crore shortfall.
United Commercial Bank (UCB) has Tk10,649 crore in classified loans and a Tk5,005 crore gap, while Standard Islami Bank has Tk4,929 crore classified loans against a Tk2,595 crore shortfall.
Mercantile Bank has Tk4,377 crore in classified loans and a Tk2,095 crore gap, while NRBC Bank has Tk3,219 crore classified loans against a Tk820 crore shortfall.
For the 10 Z-category banks for which explicit provisioning figures are available, the combined shortfall is at least Tk1.63 lakh crore. The actual gap could be higher as comparable shortfall figures are not separately available for every Z-category lender.
The concentration of classified loans is particularly stark at ICB Islamic Bank, where Tk528 crore of Tk619 crore in outstanding loans-85.2 per cent-is classified.
AB Bank follows with a 56 per cent classified-loan ratio, while National Bank and IFIC Bank have ratios of 65.7 per cent and 63.4 per cent respectively.
Another pressure point is interest suspense, which represents interest linked to troubled loans that cannot be recognised as normal cash earnings.
Islami Bank has Tk12,162 crore in interest suspense, followed by Rupali Bank with Tk6,642 crore, National Bank Tk5,658 crore, AB Bank Tk5,025 crore and IFIC Bank Tk4,190 crore.
However, not all Z-category banks are in the same position. AB Bank, despite its 56 per cent classified-loan ratio, has reported its required provision as fully met. Al-Arafah Islami Bank has Tk9,990 crore in classified loans, or 19.2 per cent of its portfolio, and has also reported full provisioning.
ICB Islamic Bank has reported a Tk17 crore provision surplus despite its exceptionally high classified-loan ratio. ONE Bank and SBAC Bank have also reported their provisions as met.
Senior officials of two affected banks said their provisioning positions are being managed under Bangladesh Bank's deferred-provisioning arrangement and that they are making provisions according to approved schedules.
One senior bank official said the arrangement is scheduled to continue until December, while another said the bank is following Bangladesh Bank instructions and working to strengthen its provision position before the deferral period ends.
But deferred provisioning does not erase bad loans-it merely spreads the financial pain over time.
Once the deferral period ends, banks with weak recoveries and large provisioning gaps could face renewed pressure on earnings and capital unless they can accelerate recoveries, generate sufficient profits or raise fresh capital.
The danger is that a new wave of defaults could simultaneously inflate classified loans, increase provisioning requirements and squeeze earnings, leaving already vulnerable banks with little room to absorb further shocks.
The wider banking sector also offers a warning. Janata Bank, although not among the 15 Z-category stocks, has Tk75,729 crore in classified loans, or 75 per cent of its loan book, and a Tk50,160 crore provisioning shortfall.
Agrani Bank has a Tk12,338 crore provisioning gap, while BASIC Bank faces a Tk5,047 crore shortfall.
The Z-category label is therefore only the visible warning. The deeper red flags are toxic-loan concentration, huge provisioning holes, weak recoveries, trapped interest income and the growing risk of capital erosion.
For the weakest lenders, the decisive test now is whether loan recoveries can accelerate fast enough to prevent today's provisioning burden from becoming tomorrow's capital crisis.
