Banking arbitrage strategy undermines Bangladesh's capital market development

Bangladesh's capital market faces a persistent challenge as banks capitalize on favorable interest rate spreads, creating a structural trap that diverts savings away from equity investments toward deposit products. The interest rate differential between bank deposits and capital market returns has incentivized financial institutions to attract deposits aggressively, reducing the flow of retail and institutional capital into shares and bonds that could fuel broader market development.

This banking arbitrage dynamic reflects a fundamental market distortion. Banks can offer competitive returns on deposits while simultaneously maintaining large spreads, creating little motivation for savers to take on the risks associated with equity market participation. The resulting capital shortage stunts the growth of Bangladesh's capital market, limiting its capacity to finance productive investments and constraining economic diversification.

The structural imbalance has implications beyond market participants. A shallow capital market restricts access to alternative financing for mid-sized enterprises and reduces the efficiency of capital allocation across the broader economy. Small and medium enterprises in particular struggle to access non-bank funding, remaining dependent on bank credit and limiting their growth potential.

Market observers note that addressing this challenge requires a multifaceted approach, including regulatory measures to encourage broader participation in capital markets and structural reforms that enhance the competitiveness and transparency of the equity market. Without intervention, Bangladesh risks maintaining a banking-centric financial system that inefficiently allocates capital and constrains the nation's economic development trajectory.
