Restoring trust in Bangladesh’s capital market: how blockchain and AI can end IPO fraud

The capital market in Bangladesh faces persistent problems with trust. IPO fraud and manipulation continue despite reforms, undermining investor confidence and impeding economic growth. Long-term stability and national development are at stake.

The nation has learned painful lessons. An estimated $27 billion in market value—roughly 22 percent of GDP at the time—was destroyed by the crashes of 1996 and, more catastrophically, 2010–2011. Millions of investors suffered losses, leaving social repercussions that still shape public perception of the stock market. The same structural flaws remain more than a decade later.

Recent enforcement data highlight the severity. The Bangladesh Securities and Exchange Commission (BSEC) fined individuals nearly Tk 1,488 crore in the past 18 months for manipulation and misconduct. Yet only a fraction has been recovered due to lengthy legal battles. This gap between punishment and accountability sends the wrong signal: wrongdoing is costly on paper but not in practice.

Systemic weaknesses drive these failures—coordinated trading through omnibus accounts, abuse of placement shares, diversion of IPO proceeds, and lack of real-time surveillance. Bangladesh’s market capitalization remains low, around 6 percent of GDP in mid-2025, compared to over 100 percent in deeper, better-run markets. This underdevelopment hampers financing for infrastructure, SMEs, and industrial growth—key to Vision 2041 and the “Smart Bangladesh” agenda.

Globally, fraud persists but is increasingly managed with technology. Scandals like Enron and Madoff spurred regulators to adopt AI for real-time surveillance. Exchanges are also testing blockchain-based settlement systems that are faster, cheaper, and more transparent. Emerging economies such as India and Brazil have embraced digital reforms, strengthening disclosure, monitoring, and enforcement.

Bangladesh, however, still relies on manual oversight and fragmented data. In an era of cyber-enabled scams, this is insufficient. For a small, fragile market, each crisis inflicts disproportionate damage and deters investors. Modern technology offers a transformative opportunity.

Blockchain can fundamentally change IPOs and securities transactions. In a permissioned blockchain, every transaction is permanently recorded, time-stamped, and visible to authorized participants. Smart contracts can automate IPO rules—ensuring funds are released only when verified conditions are met, allocations follow transparent logic, and lock-up periods cannot be bypassed. Immutable records eliminate manipulation.

AI complements this as a real-time watchdog. It can analyze trading patterns, detect unusual movements, and identify coordinated networks far faster than traditional monitoring. Leading exchanges report fewer false alarms and quicker enforcement after adopting AI-driven systems.

Together, blockchain and AI create a powerful regulatory architecture: blockchain ensures data integrity, AI provides intelligence and early warning. Such systems could flag suspicious IPO activity, trigger halts during abnormal behaviour, and deliver regulators immediate, evidence-based alerts. Privacy-preserving technologies safeguard data.

For Bangladesh, implementation can be phased. Pilot IPOs integrated with the central securities depository would allow testing and scaling. International experience shows such reforms reduce fraud risk, shorten settlement cycles, improve liquidity, and restore confidence.

A regulatory sandbox led by BSEC, with Bangladesh Bank, could test blockchain-based e-IPO systems and AI surveillance. Capacity building is vital—training regulators, auditors, and intermediaries to oversee data-driven systems. Collaboration among exchanges, the depository, banks, and technology providers will be essential.

Implementation should begin with targeted pilots: blockchain-enabled IPOs and AI surveillance in the secondary market, before scaling. This gradual approach limits disruption while signaling decisive reform.

Bangladesh is well-positioned to leapfrog. High mobile penetration, a young tech-savvy population, and strong policy backing under the Smart Bangladesh Master Plan provide a solid foundation. While advanced economies refined systems over decades, late adopters can now deploy mature technologies quickly.

The cost of inaction is clear: repeated scandals will cap growth, deter foreign investment, and push savings into informal channels. The benefits of action are equally clear: a transparent market that channels savings into productive investment, lowers risk premiums, and supports sustainable transformation.

Fraud is not inevitable—it is a governance problem that can be solved. By adopting blockchain and AI as core regulatory tools now, Bangladesh can protect investors, strengthen institutions, and become a regional leader in financial innovation. Decisive reform today will yield economic, social, and strategic dividends for decades.
