A friend doubles his portfolio in a rising market, then pledges those shares to the bank, borrows against them, and buys more. For a while, he looks like a genius. Then the market turns, the bank calls the loan, and he is selling his best stocks at the worst prices to cover it. He did not misread any single company. He misread the machine he had plugged himself into.
That machine is margin lending, and it is the least understood force on NEPSE. Most retail investors watch prices. They should be watching credit. When money borrowed against shares is cheap and plentiful, it does not just follow the market up; it pushes the market up. When that credit reverses, it does not just follow the market down; it drags the market down faster. Margin lending in Nepal is the accelerant behind the boom-bust pattern that recurs on NEPSE, and understanding it explains moves that price charts alone never will.
What margin lending actually is
Strip away the jargon, and margin lending is simple. You own shares. You pledge them to a bank or financial institution as collateral. The bank lends you a percentage of their value, and you are free to use that cash, usually to buy more shares. The loan is often called a loan against shares, a share-mortgage loan, or simply a margin loan. The mechanics are the same.
Two numbers govern it. The first is the loan-to-value ratio, the share of your collateral’s value the bank will lend. If the ratio is 70 percent and you pledge NPR 10 lakh of shares, you can borrow up to NPR 7 lakh. The second is the maintenance requirement, the minimum collateral value the bank insists you keep against the loan. Fall below it, and you get a margin call, which is a demand to add cash or shares, or to sell, until the ratio is healthy again. These two dials, set partly by the bank and partly by Nepal Rastra Bank, the central bank, decide how much leverage the whole market can carry.
The important point is not the exact number. It is that leverage turns a rupee of your own money into more than a rupee of buying power, and it does so for thousands of investors at once.
The reflexive loop that inflates a rally
Here is where mechanism becomes market-moving. Margin lending creates a feedback loop, and feedback loops do not move in straight lines.
Picture a rising market. Your shares gain value. Because the loan is a percentage of that value, your borrowing capacity rises too, without you doing anything. You draw down the new headroom and buy more shares. So do many others in the same position. That fresh buying pushes prices higher still, which lifts collateral values again, which unlocks more credit, which funds more buying. Each turn of the loop feeds the next.
This is why NEPSE rallies can feel unstoppable while they last. The rise is not only new savings entering the market. It is the same pool of shares being pledged, re-pledged, and leveraged into ever more buying power. Cheap and available credit is the fuel, and when liquidity in the banking system is loose, that fuel is abundant. The market climbs faster than earnings, dividends, or the economy would justify, because leverage has decoupled price from fundamentals for a while.
The trap is that the loop looks like skill. Investors who levered into the rally see their bets pay off and conclude they are good at picking stocks. What they are actually good at, temporarily, is being on the right side of a credit expansion.
The margin call that deflates it
Every loop that inflates on the way up deflates on the way down, and the downside runs faster than the upside.
When prices fall, collateral values fall with them. Loans that were comfortably within the limit drift toward the maintenance threshold. The bank issues margin calls. Now the investor has to find cash or sell shares fast. Many have no spare cash because they were already fully invested, so they sell. That selling pushes prices lower. Lower prices trigger more margin calls on other investors, which forces more selling. The same loop that lifted the market now pulls it down, and it does so without waiting for anyone to change their mind about any company.
This is the anatomy of a NEPSE crash that feels out of proportion to the news. A modest decline can tip leveraged accounts past their thresholds and set off a cascade of forced selling that has nothing to do with fundamentals and everything to do with mechanics. Forced sellers do not sell what they want to sell. They sell what they can, often their most liquid and highest-quality holdings, because those find buyers fastest. That is why good stocks can fall hard in a margin-driven sell-off: they are the ones being dumped to raise cash.
The cruelty of the timing is the point. Margin calls arrive precisely when prices are already falling, forcing the worst sales at the worst moments and turning a correction into something sharper.
Why NEPSE amplifies the effect
Every market with margin lending has this cycle. A few features of NEPSE make it hit harder.
The float is small. Many listed companies have a limited quantity of freely tradable shares, so it does not take enormous flows to move prices in either direction. Leveraged buying and forced selling both land with more force on a thin market. Ownership and sentiment are also concentrated and herd-driven, so a large share of investors tend to lever up together in the good times and get called together in the bad. When everyone is positioned the same way, the feedback loop has fewer shock absorbers.
There is also the concentration of collateral. When a rally is led by a handful of popular sectors or scrips, those same shares dominate the collateral pledged across the banking system. A fall in just those names can trigger disproportionate margin pressure because they are backing so many loans at once. The market’s leverage is not spread evenly; it clusters, and clusters break together.
None of this is unique in kind, only in degree. A small, concentrated, herd-prone market layered with leverage is built to overshoot in both directions.
Reading the credit cycle instead of the price
If margin lending drives the swings, then watching credit tells you more than watching price. This is the practical payoff of understanding the mechanism.
Watch liquidity and interest rates. When the banking system is flush and rates are low, margin credit is cheap and the loop can spin up. When liquidity tightens and rates rise, the fuel gets expensive, and leveraged buying fades. This is one of the channels through which NRB monetary policy moves NEPSE, and it is why the market often reacts to policy signals faster than to company results. Watch, too, for regulatory changes to the margin dials themselves. When the central bank loosens loan-to-value limits or raises per-borrower ceilings, it is adding fuel; when it tightens them, it is removing it. Those moves are leading indicators for the leverage cycle.
And watch the character of a rally. A rise on broad participation and real turnover is different from a rise driven by the same shares being pledged and re-bought on credit. The second kind is more fragile, because it depends on the loop continuing. Our guide to telling a bull market from a bear market on NEPSE leans on exactly these breadth and turnover signals.
The regulator’s dial
Margin lending is also the lever regulators reach for when a market runs hot or cold, which is why the rules keep changing.
When NEPSE is euphoric and credit-fueled, the central bank can cool it by tightening the margin dials: lowering the loan-to-value ratio, capping how much a single borrower can hold, or limiting how much of a bank’s capital can go to share loans. Each tightening removes leverage and takes some fuel out of the loop. When the market is depressed and the regulator wants to support it, it can loosen the same dials, and reporting through 2025 described exactly that direction. In mid-2025, NRB raised the ceiling on share-backed margin loans to NPR 250 million per borrower, up from NPR 150 million, and later circulars eased the limits further.
For an investor, the lesson is not to memorize the current numbers, which move. It is to understand that the regulator actively manages the market’s leverage and that a change to these rules signals where the credit cycle is headed next.
Margin lending in Nepal: a worked squeeze
Numbers make the trap concrete. Use round figures for illustration, not as advice or a forecast. Suppose you hold NPR 10 lakh of shares and pledge them at an assumed 70 percent loan-to-value ratio (the NRB and the bank set the actual ratio, and it changes). You can borrow NPR 7 lakh. You put that borrowed cash straight back into the market, so now you control NPR 17 lakh of shares on NPR 10 lakh of your own money. In a rising market this feels brilliant. A 20 percent gain on NPR 17 lakh is about NPR 3.4 lakh, a 34 percent return on your own capital. Leverage has nearly doubled your winning percentage.
Now run it the other way. The market falls 20 percent. Your NPR 17 lakh of shares are worth about NPR 13.6 lakh, but you still owe NPR 7 lakh. Your own equity has dropped from NPR 10 lakh to about NPR 6.6 lakh, a 34 percent loss, not 20. And the collateral behind your loan has shrunk, so the bank’s maintenance ratio is now under pressure. A little more downside and the margin call arrives. You either find fresh cash, which you probably do not have because you were fully invested, or you sell into the falling market to bring the loan back in line.
That forced sale is the difference between an ordinary loss and a compounded one. An unleveraged investor who simply held would be down 20 percent on paper and free to wait for a recovery. The leveraged investor is down 34 percent and, worse, has been forced to crystallize part of that loss at the bottom. Same market, same stocks, opposite outcome. The variable was the borrowed money.
What it means for you
The verdict is uncomfortable but useful. If you borrow against your shares to buy more shares, you are not just betting on the companies. You are betting on the credit cycle staying friendly, and you are handing someone else, the bank, the power to force you to sell at the worst possible time. Leverage magnifies gains in a rising market and magnifies losses in a falling one, and because margin calls compel selling into weakness, the losses tend to be the sharper of the two.
That does not make margin lending irrational for everyone. Used sparingly, with a large cushion above the maintenance threshold and cash held in reserve for calls, it is a tool. Used to the limit, in a euphoric market, by an investor with no spare cash, it is a trap that springs exactly when it hurts most. The retail investors who get hurt in every NEPSE cycle are rarely the ones who avoided leverage. They are the ones who were fully levered at the top.
Even if you never take a margin loan yourself, the cycle affects you, because it moves the whole market. The sharp, seemingly irrational sell-offs that let patient investors buy quality cheaply are often margin-driven cascades. Knowing that is an edge. When you understand that a crash is forced selling rather than a considered verdict on value, you can act on the difference between price and worth instead of being swept along by it.
Watch the credit, not just the candle. The price tells you what happened. Margin lending often tells you why and where it might go next.
