Banks' overall capital increased 3.62 percent in the last quarter of 2015 as asset quality of most banks improved.

The banks' capital stood at Tk 75,352 crore on December 31, which was 10.84 percent of their total risk-weighted assets. The amount was Tk 72,720 crore on September 30.

In line with international standards, banks have to maintain a capital adequacy ratio of 10 percent against their risk-weighted assets.

Anwarul Islam, a spokesperson for the central bank, said despite economic slowdown globally, banks' capital base in Bangladesh is gradually getting stronger. It will strengthen further in future, he added.

In the last quarter of 2015, no bank saw a capital shortfall, he said.

According to central bank statistics, the overall capital shortfall in the banking sector in September last year was Tk 44 crore; but in December, capital surplus was Tk 2,396 crore.
