Bank's Net NPA rose marginally to 0.33% in the quarter from 0.32% from the preceding three-month period. \u201cWhile in absolute terms, provisions have gone up by INR 546 Cr, almost half of the incremental provisions can be attributed to the general growth in loan book and standard asset provisions there on,\u201d Siddharth Purohit, Senior Equity Research Analyst \u2013 Banking, Angel Broking, had said in a note after HDFC Bank Q4 results were announced. Meanwhile, the parent company Housing Development Finance Corp Ltd has been gaining traction on optimism that the government\u2019s interest subsidy scheme will boost affordable housing, as reported by PTI. HDFC Ltd has already disbursed about Rs 400 crore under the plan and sees a huge growth potential going ahead. \u201cThe Credit Linked Subsidy Scheme (CLSS) to boost demand for affordable housing can be a game changer and help revive the real estate sector, which is facing a multi-year slowdown and other related industries,\u201d HDFC MD Renu Sud Karnad had said earlier last week.
