PB Fintech, the owner of Policybazaar, saw its market capitalization plummet by about $3.76 billion (₹31,400 crore) in two trading sessions, marking a nearly 39% decline in its share price. This sharp drop was triggered by the Insurance Regulatory and Development Authority of India's (IRDAI) proposed changes to insurance distribution commissions and expense limits, which could significantly impact the profitability of online insurance platforms. The company's shares fell 36% on Thursday, their worst single-day performance since their 2021 listing, and an additional 3.68% on Friday.

The regulatory proposals, issued late Wednesday, suggest tighter limits on insurers' management expenses and substantial cuts to commissions, potentially by as much as one-half to two-thirds in health, term, and motor insurance. This move is aimed at reducing distribution costs and fostering greater industry discipline. Analysts from Jefferies noted that a 10% cut in new-business commission rates could translate into a 10-12% fall in earnings for companies like PB Fintech. Motilal Oswal Financial Services estimated that the proposed rules could reduce PB Fintech’s core online insurance revenue by approximately 30% in fiscal year 2028, potentially leading to a 46% decline in earnings if not offset by cost cuts or new revenue streams.

The drastic share price movement created significant opportunities for option traders, particularly with deeply out-of-the-money put options. For instance, a POLICYBZR 29 September ₹1,500 Put option, purchased at a low of ₹0.30, could have yielded returns of nearly 87,366.7% in a single day, turning an investment of ₹105 into approximately ₹91,840. The lack of a fixed price band for F&O-listed companies like PB Fintech amplified these potential returns, allowing for substantial intraday price swings based on market sentiment and demand. Mutual funds also faced significant losses, with their holdings in PB Fintech declining by nearly $1.32 billion (₹11,000 crore) over the two-day period.
