What Is COPPER-USDT and How Does a Copper Perpetual Track the Metal

COPPER-USDT is a perpetual futures contract that tracks the price of COMEX copper, quoted in US dollars per pound. It never expires, you post USDT as margin, and each contract represents one unit of copper. Phemex files it under Metals, alongside gold and silver, and lets you take it at up to 100x leverage.

COPPER-USDT at a Glance

COPPER-USDT closed at 6.673 on the Friday 4 September 2026 Phemex daily bar, down 0.13% from 6.682 the session before. That figure is the price of a single pound of copper, and it is also a position the venue will margin at 100x. NVDA-USDT, trading on the same platform with the same USDT collateral, tops out at 10x. Copper gets ten times the leverage of Nvidia, and no published rationale explains why.

The per-pound quote, the index behind it and that leverage ceiling are three separate things, and each one catches traders arriving from crypto.

What Is COPPER-USDT?

COPPER-USDT is a USDT-margined perpetual futures contract priced on the .COPPERUSDT index, with a separate mark price under .MCOPPERUSDT. There is no expiry, no delivery month and no warehouse warrant behind it. You aren't buying copper. You're taking exposure to a number that follows copper, settled in stablecoin, and you can close the position at any hour of any day.

The contract listed on Friday 6 March 2026 at 10:30 UTC and has printed 183 daily bars through the Friday 4 September close. Tick size is 0.001, quantity steps in units of 0.01, and maximum open interest is capped at two million contracts. The contract description on the venue puts it plainly. Each contract is worth 1 COPPER.

That structure differs from an exchange-traded copper future in one way that matters most to your calendar. A COMEX contract has a delivery month, so a position you hold long enough forces a decision about rolling. A perpetual has no such date, so the decision never arrives and the cost of holding is carried through periodic funding instead. If the mechanism is new to you, our perpetual futures explainer covers it properly, and the TradFi futures primer covers how tokenized commodity and equity contracts differ from the crypto book.

One thing this article will not do is quote you a funding number. Read the funding schedule and the live rate on the contract page itself before you carry a copper position through more than a session, because that figure moves and a stale one is useless to you.

Why Does It Read 6.67 and Not 14,700?

Because copper has two conventions, and they produce numbers about 2,200 times apart for the identical metal.

US futures markets quote copper in dollars per pound. Most of the rest of the world quotes it in dollars per tonne. Convert the Friday 4 September Phemex close at 2,204.62 pounds to the tonne and 6.673 becomes roughly $14,711 per tonne. That is my arithmetic on our own close rather than a quote from any per-tonne market, and the two markets carry their own basis against each other. But the scale is the point. Think of it as the same tank of fuel priced by the litre after a lifetime of gallons. Nothing about the fuel changed, only the unit it was measured in.

This is where a headline and a trading screen stop agreeing. A story about copper holding above $14,000 a tonne tells you nothing you can act on if your position reads 6.673, and if you have not done the conversion you will read the two as unrelated markets. Our own guide to copper priced per pound lands on the same convention independently, and that makes it a useful cross-check when per-tonne figures start flying around.

The tick tells the same story in miniature. A 0.001 move on a 6.673 price is 0.015%, so the contract prices in tenths of a cent per pound. On a per-tonne screen the equivalent step would be about 22 cents. Same granularity, wildly different-looking numbers.

How Does the COPPER-USDT Index Track COMEX Copper?

The contract follows the .COPPERUSDT index rather than any single exchange print, and the gap between that index and the cash market is small but real. Two independent references for Friday 4 September put COMEX copper close together. Yahoo Finance has the HG=F front-month contract closing at 6.597. Trading Economics prints 6.58 on the same date, on a contract-for-difference basis. Those two feeds are 0.26% apart, which is tight enough to trust.

The Phemex daily bar closed at 6.673, roughly 1.2% to 1.4% above both. Some of that is contract basis. Some of it is timing, and the timing part is the trap.

The Phemex daily bar closes at 00:00 UTC, four hours after the US cash close. So the Phemex Friday bar and the COMEX Friday settlement cover different windows and are not interchangeable. The direction proves it. Across that same calendar Friday, the HG=F print was up 0.30% and Trading Economics was up 0.05%, while the Phemex daily bar was down 0.13%. Same day, same metal, opposite signs, purely because the clock boundaries differ.

Practically, that means two things for you. Do not read a difference between our close and a COMEX settlement as a mispricing to arbitrage, because a chunk of it is the extra four hours. And when you quote a copper level to anyone, say which close you mean.

Why Does Copper Get 100x Leverage When Nvidia Gets 10x?

This is the strangest fact about the contract, and it comes straight from the venue's own product data. Every figure below reads from the perpProductsV2 array, checked on Saturday 5 September 2026.

Copper gets ten times Nvidia's ceiling on the same venue, with the same USDT collateral, under the same margin engine. The obvious explanation is a clean commodity-against-equity split, and that explanation falls apart on one row. Natural gas is in the venue's own Commodities bucket, next to two crude contracts at 100x, and it is capped at 10x. Across the Stocks and Indices buckets, every contract is at 50x or below and most are at 10x.

Phemex has not published a rationale for these tiers, and I am not going to invent one on its behalf. What you can do is treat the ceiling as a fact about the contract rather than a hint about the trade. A high maximum is permission, not a recommendation, and the sizing decision is still entirely yours.

If you are moving into commodity contracts from the crypto book, what a trader should know before trading TradFi futures is the right next read.

How Do You Tell COPPER-USDT From the Copper Memecoins?

Search for copper on a crypto data feed and the metal is not what comes back first. A CoinGecko query on Saturday 5 September 2026 returned at least a dozen distinct assets carrying the name, and none of them is COMEX copper.

The memecoins. Copper (inu) trades near $0.0028 with a market cap around $2.8 million. A second token called Copper Inu, sharing the plain COPPER ticker, prints at $0.0000077 for a market cap under $$8,000. A token trading as$$COPPER carries a price with twelve zeros after the decimal point. Copper Penguin and Copper Pot of Wealth round out the field.

The tokenized wrappers, which are also not the metal. A copper miners ETF trades in tokenized form near $91 a unit. A US copper index fund and at least two mining equities have their own tokenized versions. Those follow companies that dig copper up, and a miner's share price and the metal's price come apart regularly. A producer can fall on a day copper rises, on a mine outage, a hedge book or an earnings miss.

The fix is a two-step check that takes about thirty seconds. Match on the index symbol, never on the word. On Phemex the metal is COPPER-USDT with an indexSymbol reading .COPPERUSDT, and it prints near 6.67 per pound. Then sanity-check that price against a cash copper reference. If the number in front of you is a fraction of a cent, you are looking at something that borrowed the name and it is off by five to seven orders of magnitude.

How Did Copper Behave While the Metals Market Was Closed?

Copper stopped trading in New York on Friday evening. The perpetual did not. Over the window from Friday 4 September 20:00 UTC to Saturday 5 September 11:00 UTC, measured on Phemex hourly bars, the tape looked like this.

Both metals ran under half of Bitcoin's range across the identical fifteen hours. That is one weekend on one venue and it is not a volatility estimate, so do not build a model on it. But it frames the leverage number correctly. A 100x copper position across that band works like a far smaller position on Bitcoin, and the same maximum on the venue's menu means two very different things depending on which contract you apply it to.

Volume tells the other half of it. The median Saturday daily volume across the contract's history is 1,916 against 5,071 on a median Friday, so weekend books run roughly a third as deep. Our guide to why TradFi assets can be traded 24/7 as futures covers the mechanism behind that in full.

What Are the Risks of Trading Copper at 100x?

A 1% adverse move is your whole margin. At 100x, roughly one percent against you clears the position, and that is before fees and maintenance requirements, so the real distance is shorter. Now put that against the record. Across 182 completed sessions since listing, the contract's mean absolute daily move is 1.00%, and 68 of those sessions moved more than 1%. The deepest single fall in the series is 4.57%, on Wednesday 18 March 2026, from 5.793 to 5.528. At the maximum ceiling, that one session works out to more than four times your collateral.

You are trading the index, not the metal. The contract closed 1.2% to 1.4% above two cash references on Friday 4 September. That basis can widen and it can invert, and neither move requires copper itself to do anything at all.

Weekend liquidity is thinner. Saturday volume runs around a third of a Friday, so a stop that behaves well on a Wednesday can fill somewhere unpleasant on a Sunday morning.

The calendar is closed on both sides of you. US markets are shut on Monday 7 September for Labor Day, so a reader arriving on Sunday faces a two-day closure before the cash reference reopens. The next dated catalysts are the August CPI release on Friday 11 September at 12:30 UTC and the FOMC meeting on 15 and 16 September, which carries a summary of economic projections.

No two feeds agree on where copper's high is. Yahoo Finance puts the 52-week high at 6.75 per pound. Trading Economics has recorded an all-time high of 6.83. Investing.com gives 6.8795, and a fourth reference cites 6.7. That is a spread of about 2.8% across four sources, and the Phemex contract's own listing-to-date intraday high of 6.887 prints above all four. I am not picking a winner out of that set, and you should not accept a headline about record highs without asking which feed produced it.

Frequently Asked Questions

Is COPPER-USDT the same as buying physical copper?

No. You are taking a cash-settled position on an index that follows copper, settled in USDT, with no delivery mechanism and no claim on metal in a warehouse. The exposure to price moves is similar, the ownership is not, and there is no storage or insurance cost attached to it.

Why does copper trade at 6.67 when news reports say $14,000?

Those are the same price in different units. US markets quote copper per pound, most of the rest of the world quotes it per tonne, and there are 2,204.62 pounds in a tonne. Multiply the per-pound figure by that number and the two line up within the basis between the markets.

Can I trade COPPER-USDT on a weekend when COMEX is closed?

Yes, the perpetual runs continuously. Just be aware that median Saturday volume across the contract's 183 daily bars is about a third of a median Friday, so spreads widen and a large order moves the book further than it would midweek.

What is the smallest price move on COPPER-USDT?

The tick size is 0.001, or a tenth of a cent per pound, about 0.015% of the Friday 4 September close. Position size steps in units of 0.01 contracts, so you can scale in finely without needing a large account.

Bottom Line

The number to carry away is the mismatch between a 100x ceiling and a contract whose mean daily move is 1.00%. Those two facts describe very different trades, and the second one should set your size rather than the first. Watch the basis first, because 1.2% to 1.4% above cash is where an easy-looking arbitrage turns into a timing problem, and the four-hour gap between the Phemex bar and the COMEX settlement explains part of it before any trader does anything. The next real test is the August CPI print on Friday 11 September, with the FOMC and its projections the week after, and both land after a market closure on Labor Day. Until then, size copper against its own tape rather than against the leverage the venue happens to allow.
