AMD Perpetual Margin Requirements: How Position Tiers Work

When you buy shares with borrowed money, the broker asks you for two things. You put down part of the price before the trade, and afterward you keep enough of your own money in the account to cover the loan. If that second amount runs short, the broker can sell your shares to protect itself.

Leveraged contracts run on the same two ideas, but the amounts move in ways that surprise new traders. The money you post depends on the leverage you pick, the floor you must stay above depends on how big the position is, and the exchange can change both while a trade is open.

Exchanges that list perpetual futures publish these rules as a position-tier table. Each band of position size has its own highest leverage and its own maintenance margin rate, so a small position and a very large one in the same market carry different requirements. Reading that table before you trade tells you how much money a position ties up and what keeps it open.

On BloFin, you can trade Advanced Micro Devices through the AMDUSDT Perpetual, which offers leverage of up to 20x (source: BloFin, AMDUSDT contract information). AMD's stock closed at a record $649.42 on Tuesday, October 6, 2026 (source: Yahoo Finance, AMD historical prices).

What are the AMD perpetual's margin requirements?

AMD perpetual margin requirements are two amounts: the initial margin you post to open a position, which is the position's value divided by your leverage, and the maintenance margin it has to hold to remain open. Up to 200 AMD, the maintenance margin rate is 2.50% of the position's value and the leverage cap is 20x.

BloFin works out the initial margin with a short formula. You multiply the contract size by the number of contracts and by the price, then divide by your leverage (source: BloFin Help Center, margin mechanism). In isolated margin the price is your average opening price. In cross margin it is the mark price, which BloFin builds from a weighted average of prices on several platforms (source: BloFin Help Center, margin mechanism).

Maintenance margin is the second number, and it works as a floor. It is the share of the position's value that your margin has to keep covering, and on AMDUSDT's first tier that share is 2.50% (source: BloFin, AMDUSDT position tiers). Liquidation starts when the margin, counting any running profit or loss, is no bigger than that maintenance amount plus the fee BloFin would charge to close the position (source: BloFin Help Center, Forced Liquidation Rules).

A single AMDUSDT contract is worth 0.01 AMD, so it takes 100 contracts to make one AMD (source: BloFin, AMDUSDT listing notice). Here is what one AMD ties up at four leverage settings, worked out from BloFin's formula at the October 6 close.

The margin above the maintenance line is the cushion that decides how long a position survives. The maintenance amount is the same at every leverage, because it depends only on the position's value. Only the cushion shrinks as leverage rises. At 20x it is about 16.24 USDT on a 649.42 USDT position, so a fall of about 2.5% in AMD's price uses it up. How liquidation works on a leveraged trade explains that trigger in general.

AMD perpetual margin vs buying AMD shares on margin

Buying AMD shares on margin at a US broker takes far more money up front. Regulation T, the Federal Reserve rule for share margin, caps what you can borrow at 50% of the price. FINRA then requires your equity to stay at 25% or more of the shares' value, and many brokers ask for 30% to 40% (source: SEC, buying stocks on margin).

Say you want to hold exposure to 10 AMD at the October 6 close, a position worth 6,494.20 USD. In a share margin account you would put down at least 3,247.10 USD and keep your equity above about 1,623.55 USD. On the AMDUSDT Perpetual at 20x, the same exposure needs about 324.71 USDT of initial margin and keeps about 162.36 USDT as maintenance margin.

The gap comes from what the money is for. A share margin account is a loan against shares you own. Futures margin is money you deposit and keep with your broker to back a contract, and it usually runs at 3% to 12% of the contract's value (source: CME Group, futures margin). The AMDUSDT Perpetual is a contract that tracks AMD's price and gives you no ownership of the shares (source: BloFin, stock futures notice).

Thin margin also puts the floor close. With half the price paid on shares, AMD would have to fall by about a third before your equity reached the 25% line, worked out from the loan balance. At 20x on the perpetual, the same kind of floor is about 2.5% away. That 2.50% rate holds only up to 200 AMD, and the tiers decide what happens past it.

On the perpetual, cross-margin figures follow the mark price, which is shown live on the AMDUSDT Perpetual page.

How the AMDUSDT position tiers work

AMDUSDT position tiers set the maintenance margin rate and the highest leverage by how many AMD you hold or have on order. There are eight tiers. They run from 2.50% and 20x on positions up to 200 AMD to 50% and 1x above 100,000 AMD, and each step up in size raises the rate and lowers the cap.

The first four tiers cover the positions most retail traders hold.

Above 10,000 AMD the rates keep climbing. They reach 12.50% at 4x, then 16.67% at 3x and 25.00% at 2x, and finally 50.00% at 1x for positions from 100,000.01 to 200,000 AMD (source: BloFin, AMDUSDT position tiers). BloFin shows the same eight rows whether you pick cross or isolated margin.

BloFin's tier table counts AMD. The note on the same page says the highest leverage depends on the number of contracts in what you hold, what you have on order and any order you are placing (source: BloFin, AMDUSDT position tiers). Both describe the same line, because 200 AMD is 20,000 contracts. Two things follow from that. A limit order waiting to fill already counts toward your tier, and the price of AMD has no effect on which tier you are in.

A pattern also runs through the tiers. At each tier's highest leverage, the initial margin is exactly twice the maintenance margin rate, worked out from BloFin's tiers: 5% against 2.50% at 20x, and 20% against 10% at 5x. So a position opened at its tier's top leverage starts with half of its margin above the maintenance line. A move against it of about the maintenance rate is enough to use that half up.

Why maximum leverage falls as an AMD position grows

The cap falls as size grows because a big position is harder to close at a fair price when it fails. Once a position reaches its liquidation price, BloFin's liquidation engine steps in and sells or buys the position back into the market. When that fill comes out worse than the liquidation price, the insurance fund covers the gap (source: BloFin Help Center, Forced Liquidation Rules).

A position of a few AMD can be closed against the first orders waiting in the order book. A position of several thousand AMD needs many more buyers or sellers, and each one further down the book trades at a worse price. A thicker layer of margin gives the engine more room to close it before a shortfall reaches the fund. A lower leverage cap does the same job from the other side, because it forces more margin in at the start.

BloFin describes its tier updates as a way to support market liquidity and manage risk (source: BloFin, May 20, 2026 tier notice). The size of the first tier also differs a great deal by market. BloFin's Bitcoin perpetual allows 150x with a 0.30% maintenance rate on positions up to 2.5 BTC (source: BloFin, Bitcoin perpetual position tiers). AMD's first tier asks for more than eight times that rate.

AMD's market also has quiet periods that a crypto market lacks. Outside the stock's regular trading hours, BloFin's listing notice warns that the underlying may move only a little and trade thinly (source: BloFin, AMDUSDT listing notice). A higher maintenance rate and a lower cap leave more margin in place for the moment trading picks up again.

Which tier a typical AMD position sits in

A typical AMD position sits well within the first tier. That tier runs to 200 AMD, worth 129,884 USDT at the October 6 close of $649.42. A trader opening a few AMD therefore gets the full 20x cap and the 2.50% maintenance rate at any leverage they choose.

Say you put 200 USDT of margin behind an AMD long at 5x. The position is worth 1,000 USDT, or about 1.54 AMD, which is under 1% of the way to the 200 AMD line. Even a long worth 20,000 USDT, a large position for most retail accounts, comes to about 30.8 AMD and is still far from the second tier.

The second tier only matters for positions worth six figures in USDT. At 20x, a position of exactly 200 AMD needs 6,494.20 USDT of margin at the October 6 price. Anything past that line falls under the 15x cap and the 3.33% rate. Because the tier is counted in AMD, its USDT value moves with the share price, so the same 200 AMD line is a smaller USDT figure when AMD is cheaper and a bigger one when AMD costs more.

One account setting changes the picture. BloFin's Multi-Position mode lets you hold several separate positions in the same contract and direction, each with its own margin, leverage and stop-loss (source: BloFin Help Center, Multi-Position FAQ). The mode has its own tier table. On AMDUSDT, a single position reaches the second tier above 20 AMD, and all your positions together share a 200 AMD limit for the first tier's terms (source: BloFin, AMDUSDT position tiers).

At the October 6 close, 20 AMD is worth about 12,988 USDT. In Multi-Position mode a mid-sized AMD position can therefore hit the 15x cap far sooner than in the standard mode. BloFin checks the combined size of all your positions and open orders in the same direction when you place an order or change leverage (source: BloFin Help Center, Multi-Position FAQ). Splitting a trade into pieces therefore does not get around the limit.

What an AMD rally does to your margin and your tier

An AMD rally never moves a position into a higher tier, because BloFin counts tiers in AMD. What a rally changes is the position's value, so the maintenance margin in USDT grows with it. A long's profit more than pays for that, while a short gets squeezed from both sides at once.

Take a long of 150 AMD. At the October 6 close of $649.42 it is worth 97,413.00 USDT, and its maintenance margin at 2.50% is about 2,435 USDT. If AMD rose 20% to 779.30 USDT, the position would be worth 116,895.60 USDT, with a maintenance margin of about 2,922 USDT. It would still sit in the first tier, because 150 AMD is under 200 AMD. Its profit of about 19,483 USDT would cover the higher floor many times over.

A short works the other way. Say you are short 5 AMD at 5x from 649.42 USDT, with 649.42 USDT of margin and a maintenance margin of about 81.18 USDT. If AMD rises 10% to about 714.36 USDT, the loss of about 324.71 USDT halves your margin. At the same time the maintenance margin rises to about 89.30 USDT, because the position you owe is now worth more. A rally against a short eats the margin and raises the floor together.

Size changes the tier only when you add to it. Say you hold 150 AMD and place a limit order for 100 more. BloFin adds the position, open orders and the new order together, so the total of 250 AMD falls in the second tier, where the cap is 15x and the rate 3.33% (source: BloFin, AMDUSDT position tiers). The most leverage available drops from 20x to 15x, and running the larger position at 15x takes more margin than running the smaller one at 20x did.

The same counting applies when you build a position in steps over several weeks. Each addition is checked against the tier table in force on the day you place it. A long that started small can end up with a lower cap and a higher maintenance rate once it passes 200 AMD.

Isolated vs cross margin for the AMDUSDT Perpetual

Isolated margin suits most AMD positions. It ties a fixed sum of margin to one position, and that sum caps what the position can cost you. Cross margin pools the free money in your futures account behind every open position, so a loss on any of them is paid from the same pot.

BloFin's margin guide sets out the difference. In isolated mode, the margin you lock in when you place the order is the position's maximum loss, and the rest of the futures account is untouched if the position is liquidated. In cross mode, all of the account's money counts as margin and the risks of every position are added up together. A major move can then take the whole account to zero (source: BloFin Help Center, margin mechanism).

Two things make the choice sharper on a stock contract. First, BloFin may accept only orders that reduce or close stock futures positions outside regular weekday trading hours, and on weekends and market holidays (source: BloFin, stock futures notice). Second, crypto perpetuals in the same account keep trading through those hours. In cross margin, an AMD position you can only cut shares its backing with positions that are still moving.

Say you have 2,000 USDT in your futures account and open a 3 AMD long at 5x, with about 389.65 USDT of margin. In isolated mode the worst outcome is losing those 389.65 USDT, and the other 1,610.35 USDT stays out of the trade. In cross mode the whole 2,000 USDT stands behind the long, so it survives a deeper fall. A fall that deep then costs more than 389.65 USDT.

Cross margin still has real uses. It suits a set of related positions that are meant to offset each other, and BloFin's risk guide names hedging as one case where cross margin makes sense. That is why some traders who hedge pick it, although BloFin's guide to hedging spot crypto with perpetuals recommends isolated margin for nearly every hedge. For a first AMD position, isolated margin keeps the worst case equal to a number you chose before you clicked, and choosing a margin mode on BloFin walks through the trade-off for any contract.

Cross margin with a Bitcoin perpetual over a weekend

Cross margin ties an AMD position to everything else in the account, and a weekend shows that most clearly. BloFin lists the running profit or loss of your other cross positions as one of the things that move a cross position's estimated liquidation price (source: BloFin Help Center, Forced Liquidation Rules).

Say your futures account holds 1,000 USDT in cross margin. You are long 2 AMD at 10x from 649.42 USDT, and you also hold a long position in a Bitcoin perpetual worth 8,000 USDT. With Bitcoin flat, BloFin's formula for two or more cross positions puts the AMD leg's estimated liquidation price at about 168 USDT, far below the market (source: BloFin Help Center, Liquidation Price Calculation).

Now say Bitcoin falls 10% on a Saturday while AMD's price barely moves. The 800 USDT loss comes out of the same balance. The AMD leg's estimated liquidation price climbs to about 577 USDT, only about 11.1% below where AMD stopped. A fall of about 11.8% in Bitcoin would take the whole account's margin ratio to 100% without AMD's price changing at all, and at that level BloFin may reduce or liquidate positions (source: BloFin Help Center, Forced Liquidation Rules). Over a weekend, BloFin may also accept only orders that cut the AMD leg.

In isolated mode the same AMD long would carry 129.88 USDT of margin and an estimated liquidation price near 599.83 USDT. That price is closer to the market, but it stays put whatever Bitcoin does, and the AMD long can lose at most its 129.88 USDT. All these figures are worked out from BloFin's formulas. The Bitcoin position uses the 0.30% rate from BloFin's first Bitcoin tier (source: BloFin, Bitcoin perpetual position tiers). The closing fee is 0.06%, BloFin's standard futures taker fee and the rate its own worked example uses (source: BloFin Help Center, Forced Liquidation Rules).

Multi-currency margin and Bitcoin as collateral

Multi-currency margin lets coins other than USDT, such as Bitcoin, back your futures positions. It is one of the account modes of BloFin's unified trading account, and it needs trading account equity of at least 10,000 USDT before you can switch it on.

In this mode BloFin values your collateral in US dollars across every asset you hold, so a Bitcoin balance can support an AMD position without being sold first. The same rule ties the two prices together. The value backing your AMD position moves with Bitcoin's price, even on a day when AMD's own price stands still.

The cost of that flexibility is spelled out in the same guide. In multi-currency mode the account can end up owing money, and if futures losses pass certain levels, BloFin may sell spot assets to cover them. You also need to close every position and cancel every open order before you change account mode, so the switch has to be planned for a moment when you hold no AMD position.

Multi-currency margin also rules out one other setting. BloFin's Multi-Position mode needs single-currency margin, so it is unavailable in multi-currency mode (source: BloFin Help Center, Multi-Position FAQ). For an AMD position that may sit in a reduce-only period over a weekend while Bitcoin keeps trading, USDT in isolated margin keeps the AMD leg's risk tied to AMD alone.

What happens to an open AMD position when BloFin changes the tiers

When BloFin changes AMD's tiers or leverage, its tier notices say positions opened before the update are not affected. New orders are checked against the updated tier table. The same notices warn that maintenance margin ratios may change and advise cutting leverage by adding margin or closing positions, so check any open AMD position after an update.

AMD has been through one such change already. When the contract listed on May 6, 2026, at 2PM UTC, its leverage range was 1-10X (source: BloFin, AMDUSDT listing notice). BloFin's notice of May 20, 2026 then replaced the AMDUSDT tiers with the table in force today (source: BloFin, May 20, 2026 tier notice). Before it, the first tier covered only 10 AMD, at a 5% maintenance rate and 10x. The second ran to 20 AMD at 10% and 5x, and positions up to 200 AMD sat in a third tier at 12.5% and 4x.

Say you held 50 AMD under the old table. That was a third-tier position, capped at 4x and keeping 12.5% of its value as maintenance margin. Under the new table the same 50 AMD can run at up to 20x with a 2.50% rate. A 5 AMD position stayed in the first tier, but its maintenance rate halved from 5% to 2.50% and its cap doubled to 20x. Both comparisons are worked out from the contract counts in the notice.

The May 20 notice carries both the protection for open positions and the risk warning, and it adds that the change covered cross and isolated positions alike (source: BloFin, May 20, 2026 tier notice).

Changes can also arrive without a notice of their own. BloFin's contract page says the platform adjusts its parameters to market conditions with no separate announcement (source: BloFin, AMDUSDT contract information). Its Parameter Adjustments page shows upcoming changes to position tiers and other settings before they take effect, and BloFin can still cancel or modify any of them (source: BloFin, Parameter Adjustments). A cut to AMD's caps would matter most to a position close to the edge of its tier. Read the tier table on the day you add to a position, since that is the table a new order is checked against.

Checking your AMD margin before an order

Before an AMD order, check five things: the initial margin at your leverage, the cushion above the 2.50% maintenance line and the tier your total in AMD falls in, open orders included. Then check your margin mode, and whether you will hold the position outside regular weekday trading hours, or over a weekend or market holiday, before you exit.

1. Initial margin is the position's value divided by your leverage. At the October 6 close that is 32.47 USDT per AMD at 20x and 129.88 USDT per AMD at 5x.

2. The cushion is your margin minus 2.50% of the position's value. At 20x it is about 2.5% of AMD's price, and at 5x about 17.5%.

3. The tier counts what you hold, your open orders and the new order, in AMD. Under 200 AMD keeps 20x and 2.50%, or under 20 AMD per position in Multi-Position mode.

4. Isolated margin limits an AMD position's worst loss to the margin behind it, and cross margin is for positions you deliberately want to share one balance.

5. Outside regular weekday trading hours, and on weekends and market holidays, BloFin may accept only orders that reduce the AMD position, so you may not be able to add to it (source: BloFin, stock futures notice).

Before you place a 2 AMD long at 10x in isolated mode, the five checks give you its numbers. It ties up 129.88 USDT and keeps about 32.47 USDT as maintenance margin. It sits in the first tier with room for 198 more AMD, and it can lose at most its 129.88 USDT of margin if a weekend move goes against it.

Frequently asked questions

How much margin does 1,000 USDT of AMD perpetual exposure need?

A 1,000 USDT position on the AMD perpetual needs 50 USDT of initial margin at 20x, 100 USDT at 10x, 200 USDT at 5x and the full 1,000 USDT at 1x. BloFin works it out by dividing the position's value by your leverage (source: BloFin Help Center, margin mechanism). Its maintenance margin is 25 USDT at the first tier's 2.50% rate. At 20x that leaves only 25 USDT between the margin you posted and the maintenance line, so a move of about 2.5% against you reaches it.

Is there a margin call on the AMD perpetual?

On the AMD perpetual, falling to the maintenance line leads straight to a partial reduction or liquidation. In exchange-traded futures, dropping below maintenance margin can bring a margin call asking you to top the account back up to the initial level, with liquidation as the fallback (source: CME Group, futures margin). On BloFin, once the mark price reaches your liquidation price, BloFin's liquidation engine takes control of the position, and it is locked against margin changes and new orders (source: BloFin Help Center, Forced Liquidation Rules). Adding margin earlier is how you move that price away.

Why does a cross-margin liquidation price move while AMD's price stands still?

In cross margin, an AMD position's estimated liquidation price depends on the whole futures account, so it moves whenever the account does. BloFin lists five causes: profit or loss on your other cross positions, opening other positions, transfers into or out of the account, trading fees, and funding payments paid or received (source: BloFin Help Center, Forced Liquidation Rules). In isolated mode only two things move it: changes to the position's own margin and its funding settlements.

Do long and short AMD positions share a liquidation price in cross margin?

A long and a short in the same pair share one estimated liquidation price in cross margin, because BloFin treats them as hedged against each other. In isolated mode each side keeps its own margin, so the long and the short each get their own estimated liquidation price (source: BloFin Help Center, Forced Liquidation Rules). If you run both sides of AMD at once, for example to protect a profit over a weekend, cross margin judges the pair as one exposure while isolated margin judges each leg on its own.

Does unrealized profit count toward margin on the AMD perpetual?

Unrealized profit and loss both count toward the AMD perpetual's margin ratio, the measure BloFin uses to decide when to liquidate. In isolated mode the ratio is the position's margin plus its profit or loss, divided by its maintenance margin plus the transaction fee. In cross mode it is the account balance plus the profit or loss of every position, divided by their total maintenance margin and fees (source: BloFin Help Center, Liquidation Price Calculation). A winning AMD long lifts its own ratio, and in cross mode it also props up every other position.

Nothing in this article constitutes financial advice, and nothing in it is a recommendation to buy, sell or hold AMD in any form. At 20x, an AMDUSDT Perpetual position opens with only about 2.5% of AMD's price between its margin and the maintenance line, and BloFin can change the tiers that set that line. In cross margin, a loss on another position can liquidate the AMD leg and take the whole futures balance. That includes a crypto loss outside regular weekday trading hours, and on weekends and market holidays, when BloFin may accept only orders that reduce an AMD position. In multi-currency mode BloFin may also sell spot assets to cover futures losses. Past performance does not indicate future results.
