Crypto perpetual futures are derivative contracts that let you trade the price of an asset like Bitcoin, long or short, with leverage, without owning it and without an expiry date. A funding rate mechanism keeps the contract’s price anchored to the spot market.
That is the short answer. The rest of this guide unpacks every word of it, with worked examples in rupees, because perpetuals are the single most traded crypto instrument in the world and the least well explained in an Indian context.
The Problem: Spot Trading Only Lets You Win One Way
Most Indian traders meet crypto through spot trading: you pay ₹1,00,000, you receive ₹1,00,000 worth of Bitcoin, and you wait. It is simple, and that simplicity carries three structural limitations that experienced traders feel quickly.
First, the spot is one-directional. You profit only if the price rises. If you believe Bitcoin is overheated and likely to fall, spot gives you no way to act on that view except selling what you hold or sitting out entirely. Half of every market cycle is invisible to you as an opportunity.
Second, the spot is capital-inefficient. To take ₹5,00,000 of exposure, you must deploy ₹5,00,000. There is no concept of margin. For a trader managing risk across positions, locking full notional value into every idea is expensive.
Third, in India, the spot structure has a specific cost: every sale of a virtual digital asset is a taxable transfer, attracting a flat 30% tax on gains with no set-off against losses, plus 1% TDS deducted on the transaction itself. Active spot trading means meeting that regime on every round trip. (How derivative contracts differ structurally is its own topic, we cover it in detail in our guide to crypto taxation in India)
Derivatives and perpetual futures specifically exist to solve the first two problems, and they change the structure of the third. Here is how they work.
The Solution: Futures Without an Expiry Date
Start with what a futures contract is
A futures contract is an agreement to buy or sell an asset at a price agreed today. You are not exchanging the asset itself; you are trading a contract whose value moves with the asset’s price. India’s equity markets run on exactly this instrument, anyone who has traded Nifty or BankNifty futures has traded the same machinery. The contract is the product; the index is just the reference.
Traditional futures have one defining constraint: an expiry date. A monthly Nifty contract settles on its expiry Thursday, positions close or roll, and a new contract begins. Expiry creates rollover costs, calendar pressure, and an entire sub-industry of expiry-day behaviour.
The perpetual twist: remove the expiry
A perpetual future, a “perp”, is a futures contract with the expiry deleted. You can hold a position for ten minutes or ten months. There is no settlement Thursday, no rollover, no contract month to track. You open a position; it stays open until you close it or until your margin can no longer support it.
This raises an obvious question. Expiry is what forces a normal futures price to converge with the real asset’s price on settlement day, the contract must equal reality. Remove expiry, and what stops the contract price from drifting away from the actual Bitcoin price entirely?
The funding rate: the anchor that replaces expiry
The answer is the funding rate – a small periodic payment exchanged directly between traders, not paid to the exchange. The logic is a self-correcting tug of war:
- When the perpetual trades above the spot price, longs pay a small fee. Being long becomes slightly expensive, being short becomes slightly rewarding, and selling pressure pulls the perp back down toward the spot.
- When the perpetual trades below spot, the flow reverses: shorts pay longs, and buying pressure pulls the price back up.
Think of it as a deposit-and-demand mechanism: whichever side of the rope is overcrowded pays a small toll for the crowding, until the rope re-centres. Funding is typically exchanged at fixed intervals through the day, and on a calm market it is a small fraction of a percent. It matters for positions held across many funding cycles; for short-duration trades it is usually a rounding error. We break the full mechanics and costs down separately.
Margin and leverage: trading exposure, not ownership
Because you never take delivery of the asset, you do not need to fund the full position. You post margin – a fraction of the position’s value held as collateral, and the contract gives you exposure to the whole position. The ratio between the two is leverage.
The everyday parallel is token money on a property booking: a ₹5 lakh token can secure a ₹50 lakh flat, and until the deal concludes, every lakh the property’s market value moves is a full lakh of change in your position, measured against your ₹5 lakh, not the ₹50 lakh. That is 10x leverage, and it cuts both ways with complete symmetry.
On NIYAM, leverage on perpetuals is available up to 25x. The right number for any given trade is almost always far below the maximum, a point important enough that we treat it as its own subject.
Long and short: the two-directional market
A perpetual position has two doors. Going long means you profit if the price rises – the familiar direction. Going short means you open a position that profits if price falls, without ever owning or borrowing the asset. The contract simply pays the difference in the direction you chose. For traders coming from spot, this is the single biggest practical upgrade: a falling market stops being dead time and becomes a market like any other.
Mark price: the price that actually governs your position
One more concept completes the picture. Exchanges track several prices simultaneously: the last traded price (whatever the most recent trade printed at), the index price (a blend of major spot markets), and the mark price – a smoothed, manipulation-resistant fair value derived from the index. Your unrealised P&L and, critically, your liquidation are calculated on the mark price, not the last traded price. This protects you from a single thin-market wick wiping out a sound position. It also surprises every new perpetuals trader at least once, which is why it gets a full explainer of its own.
A Worked Example, in Rupees
Assume Bitcoin’s perpetual is trading at ₹50,00,000 per BTC (a hypothetical round number for clean arithmetic). You believe the price is headed up. You have ₹1,00,000 to commit and you select 5x leverage.
| Item | Value |
|---|---|
|
Margin posted |
₹1,00,000 |
|
Leverage selected |
5x |
|
Position size (exposure) |
₹5,00,000 – i.e. 0.1 BTC |
|
Direction |
Long |
Scenario one: Bitcoin rises 4% to ₹52,00,000. Your 0.1 BTC position is now worth ₹5,20,000. The ₹20,000 gain is yours in full – a 20% return on the ₹1,00,000 margin, because a 4% move travelled through 5x leverage.
Scenario two: Bitcoin falls 4% instead. The identical arithmetic runs in reverse: the position loses ₹20,000, and your margin is down 20%. Leverage has no opinion about direction. It multiplied the move both times.
Scenario three: the move keeps going against you. At 5x leverage, an adverse move approaching 20% would consume essentially all of your margin and the exchange will close the position before that point, at the liquidation price, once your remaining margin falls to the maintenance threshold. The exact level depends on the contract’s maintenance margin requirements and fees, but the principle is universal: the higher the leverage, the shorter the distance between your entry and your liquidation. At 25x, that distance is under 4%. This is why position sizing, not direction-picking, is the skill that keeps accounts alive.
If You Trade Nifty Futures, You Already Know Most of This
Margin, leverage, mark-to-market, long and short – every load-bearing concept in this article has a direct counterpart in Indian equity F&O. A BTC perpetual is, mechanically, closer to a Nifty future than to anything else in crypto: same grammar, different underlying, with two real differences – no expiry (funding replaces it) and a market that never closes. For equity derivatives traders, we have written a full side-by-side comparison of the two instruments, including what transfers directly and what needs unlearning.
Conclusion: A Contract Built for Traders, Not Holders
Perpetual futures take the futures contract India’s markets already run on, remove the expiry, and replace it with a funding mechanism that keeps the price honest. The result is an instrument that trades in both directions, around the clock, with capital efficiency that spot cannot offer – Settled, on NIYAM, entirely in rupees, in and out.
None of that makes perpetuals easy. Leverage is symmetric, liquidation is real, and the traders who last are the ones who learn the machinery before they commit capital to it. That order of operations – understand first, trade second, is the entire premise NIYAM is built on.
The fastest way to make these concepts concrete is to trade them without money on the line: open a paper trading account on NIYAM and run the worked example above yourself. For the structured version of this education, NIYAM Academy’s derivatives curriculum starts exactly where this article ends.
Frequently Asked Questions
Are perpetual futures legal to trade in India?
There is no Indian law prohibiting the trading of crypto derivatives. INR-settled perpetual contracts are offered by Indian platforms operating within the Indian banking system, and profits are taxable income that must be reported. The regulatory landscape for virtual digital assets continues to evolve, so staying informed is part of the discipline.
Do perpetual futures ever expire?
No. That is the defining feature. A position remains open until you close it or until it is liquidated. The funding rate, exchanged periodically between long and short traders, performs the price-anchoring role that expiry performs in traditional futures.
How much money do I need to start?
Because perpetuals are margin-based, the entry point is a function of position size and leverage rather than a fixed ticket. The more useful question is how much you can afford to risk per trade – a sizing question we address in our risk management guide. Starting with paper trading costs nothing at all.
How are perpetual futures taxed in India?
Derivative contracts are structured differently from spot VDA transfers, and the difference matters for how the 30% VDA tax and 1% TDS provisions apply. We cover the framework factually and in detail in our dedicated guide to crypto tax in India and on any tax question, consult a qualified tax professional for your specific situation.
