On October 5, the Securities Board of Nepal put its advance-notice rule into force: any substantial shareholder of a listed company intending to sell 5 percent or more of their holding had to notify the company in writing 15 days before the sale, with the notice published through NEPSE. The market heard a sell signal. The index fell 20.48 points that Monday to close at 2,566.76, on turnover of Rs 3.27 billion that was thinner than Friday's Rs 3.89 billion. Of the 359 companies traded, 242 saw their prices fall and only 32 rose. This blog walked through the mechanism: each published notice was a scheduled supply event, and buyers responded by waiting.

The pushback came from two directions at once. Market participants told the press the measure had weakened investor confidence, with investors bracing for heavier founder selling after lock-in periods expire, according to The Farsight Nepal. And the House of Representatives' Finance Committee, the parliamentary body overseeing the market, directed SEBON to reconsider the provision as part of its capital-market package. A regulator whose flagship transparency measure is publicly questioned by its own overseers within days has a problem that no concept paper can fix.

The rewrite arrived within the week. According to Banking News, which reported the Board's Regulation Department letter addressed to all listed companies, the rule now works like this: substantial shareholders must inform the company five trading days in advance, and only when they plan to sell 15 percent or more of the shares they own. The letter cites Section 48, Sub-section (1) of the Securities Act, 2063 as the authority. The mechanics of disclosure stay the same: a shareholder who announces an intended sale and then sells less, or nothing, must inform the company again after the deal, and the company must make the outcome public through NEPSE.

Put the two versions side by side and the retreat is visible in the numbers. The trigger tripled, from 5 percent of a holding to 15 percent. The window shrank from 15 days to five trading days, which in Nepal's trading week is roughly one calendar week. A concrete case shows what that means. Take a promoter who owns 10 percent of a listed company and wants to sell a tenth of that stake, about 1 percent of the company. Under the old rule the sale had to be pre-announced. Under the new rule it moves with no advance notice at all, because the sale is below the 15 percent bar. Only disposals large enough to reshape the seller's own position still have to be declared early, and even then the market gets a week of warning instead of two.

The original version failed for a reason worth naming, because the reason has not gone away. An advance notice of a sale does not just inform the market. It gives every buyer a reason to postpone, which presses the price down before a single share changes hands. In the weeks after the rule took effect, Banking News counted 33 shareholders notifying the sale of 75 lakh shares, published one after another on NEPSE. Each notice was transparent. Each notice was also a warning that supply was coming. The warning became the overhang, and the market priced the overhang in. Shortening the window from two weeks to one reduces the damage, but it does not remove the mechanism. A five-day warning still warns.

There is also the question of who the rule covers. The notice obligation applies only to sellers, while large buyers can keep accumulating in silence, an asymmetry that market commentators flagged from the start. South Korea, which faced the same debate, chose a different shape for its rule: shareholders with 10 percent or more must pre-disclose sales of more than 1 percent of a company's issued shares, 30 to 90 days before the trade, and its revision covers both buying and selling, according to KED Global. Korea's trigger is far lower than Nepal's new one, but it applies on both sides of the order book and it has lasted. Nepal's original rule sat between Korea's strictness and nothing. The rewritten one sits much closer to nothing for mid-size sales, and it keeps the one-sided design.

A few limits are worth stating plainly. The amendment reached the market as a regulator-to-company letter, not a public circular on SEBON's notices board, and every figure about the new terms traces to Banking News's reporting of that letter. There is also no track record to judge either version by. The original rule lived about a week, which means neither its costs nor its benefits have had time to show in data. A single week's market move never proves a rule wrong: the October 5 fall mixed dividend-season price adjustments with the rule's debut, and the week ended higher at 2,591.81. What the evidence does show is speed. A rule announced, defended in a concept paper, challenged by Parliament, and rewritten within days is a rule the market never got a chance to believe in.

There is a genuine dilemma underneath the politics, and neither side is obviously wrong. Sudden promoter dumps have burned retail investors before, and a market where insiders sell without warning is not a fair market. But rules written at this speed become part of the noise they were meant to calm. The question hanging over the new five-day rule is not whether early warning protects investors. It is whether a regulator that rewrote its flagship transparency measure within days, by letter, can make anyone believe the next version will last long enough to matter.
