Binance Tightens Funding Controls on Nine TradFi Perpetuals

Effective from September 10 at 08:15 UTC, funding on MEITUANUSDT, KUAISHOUUSDT, GIGADEVUSDT, POPMARTUSDT, TENCENTUSDT, HK1810USDT, HK0700USDT, ZHIPUUSDT and MINIMAXUSDT moved from once every eight hours to once every four hours.

The funding cap and floor were simultaneously reduced from ±2% to ±1%. The final ±2% settlement applied at 08:00 UTC on September 10, with the ±1% limits taking effect from the 12:00 UTC funding period onward.

Binance said the adjustment forms part of its continuing review of products and services. More importantly, the exchange reiterated that it can alter contract specifications according to market-risk conditions, including funding fees, tick sizes, maximum leverage, initial margin and maintenance margin requirements.

The contracts are also exempt from Binance’s normal rule that can automatically shorten funding intervals to one hour when a contract repeatedly reaches its funding cap or floor. If Binance decides that these TradFi contracts require one-hour funding, it will make that change separately.

The adjustment covers a concentrated group of relatively new equity-linked products.

Binance launched MINIMAXUSDT and ZHIPUUSDT on July 17, followed on July 22 by HK0700USDT, HK1810USDT and TENCENTUSDT. The underlying shares include MiniMax Group, Zhipu AI, Tencent and Xiaomi.

The structure also illustrates how Binance is experimenting with different ways of replicating traditional equities.

TENCENTUSDT is a USDT-priced contract in which the underlying Hong Kong share price is translated using an HKD/USD foreign-exchange rate. HK0700USDT provides exposure to the same Tencent shares through a quanto structure: the contract is priced using the local-currency equity price while profits and losses are settled in USDT, limiting the trader’s direct cross-currency exposure.

POPMARTUSDT followed on July 23 with Pop Mart International as its underlying equity. At launch, Binance gave the contract a ±2% funding cap, eight-hour funding intervals and leverage of up to 25 times.

GIGADEVUSDT, tracking GigaDevice Semiconductor’s Hong Kong-listed H shares, arrived on August 3 under the same initial ±2% and eight-hour funding framework.

KUAISHOUUSDT and MEITUANUSDT were then added on August 11, extending Binance’s equity-linked lineup further into major Hong Kong technology and consumer names.

That means Binance is already modifying the financing mechanics of contracts that in some cases have been trading for less than two months.

The September 10 changes are also not isolated.

Just six days earlier, Binance made the same eight-hour-to-four-hour shift and reduced funding limits to ±1% for another nine TradFi contracts, including KODEX200USDT, NAVERUSDT, LGELECTRONICSUSDT, HANMIUSDT, SAMSUNGEMUSDT, CXMTUSDT and ZHONGJIUSDT, as well as leveraged Samsung Electronics and SK Hynix-linked products.

An earlier adjustment in July affected SKHYNIXUSDT, SAMSUNGUSDT and HYUNDAIUSDT. In that case Binance moved funding from eight hours to four hours and tightened the cap even further, to ±0.50%.

The exchange has been changing other parts of the TradFi infrastructure as well.

On August 31, Binance modified the mark-price calculation used by its TradFi perpetuals, expanding one moving-average component from a 30-second to a one-minute basis. The mark price is important because it feeds into unrealized profit and loss and liquidation calculations.

Earlier, in May, Binance replaced the fixed pricing method used for equity-based perpetuals during underlying-market closures with an order-book exponentially weighted moving average model. The change was designed to provide a dynamic pricing mechanism during maintenance periods, weekends and holidays when the traditional exchange supplying the underlying share price is closed.

That problem exists because Binance’s TradFi perpetual contracts trade around the clock even when the stocks underneath them do not.

Binance formally launched the TradFi perpetual product category in January, pitching it as a way to give users 24/7 exposure to traditional markets through familiar USDT-settled contracts without expiry dates. The exchange acknowledged from the outset that continuous trading requires additional pricing and risk controls when the underlying market is closed.

The September funding changes suggest that those controls are continuing to evolve as the equity-perpetual universe grows.

The Risk Framework Is Becoming the More Important Story

At first glance, moving funding from eight hours to four hours looks like a minor technical change.

It is more revealing when viewed alongside everything Binance has changed over the past several months.

The exchange has gone from launching TradFi perpetuals to repeatedly recalibrating funding intervals, funding limits, mark-price calculations and off-hours pricing. That is what should happen as a new derivatives market grows: risk management becomes less about the specifications chosen on launch day and more about what actual trading behavior shows after launch.

Funding is particularly important here.

Perpetual futures have no expiry date, so there is no conventional settlement date forcing their price back toward the underlying asset. Instead, payments pass between long and short traders to discourage the perpetual contract from drifting too far away from its reference market. When funding is positive, longs generally pay shorts; when it is negative, shorts pay longs.

Halving the settlement interval allows that balancing mechanism to operate twice as often.

But there is an important nuance in describing the reduction from ±2% to ±1%.

The maximum rate per settlement has been halved, but settlements now occur twice as frequently. In simple terms, two theoretical ±1% funding events over eight hours can still amount to roughly the same maximum funding burden as one ±2% event over eight hours.

So this is not simply Binance making funding cheaper.

It is changing how frequently funding pressure is released.

That can matter significantly in an equity perpetual market, particularly outside Hong Kong trading hours. Binance users can continue trading Tencent, Xiaomi or Meituan-linked perpetuals while the HKEX shares used as the economic reference are closed. During those periods, crypto-native positioning can move while the underlying equity cannot immediately provide fresh price discovery.

A shorter funding cycle gives Binance a more frequent mechanism for discouraging an increasingly one-sided perpetual market.

The repeated nature of the changes is arguably the strongest signal.

Nine other TradFi contracts received essentially the same treatment on September 4. Korean equity perpetuals were adjusted in July. Binance has separately changed its mark-price and off-hours price-index methodology.

That looks less like emergency intervention in one problematic contract and more like the development of a standard operating framework for an asset class that behaves differently from ordinary crypto perpetuals.

There is another reason this deserves attention.

Binance is effectively putting traditional shares inside crypto-market infrastructure: 24/7 trading, USDT settlement, perpetual contracts and substantial leverage. That removes several characteristics investors normally associate with equity markets, including exchange opening hours and direct ownership of the underlying security.

It also creates risks traditional stock brokers rarely have to manage.

A major company announcement can occur while the underlying stock is closed but the Binance contract remains active. Weekend geopolitical news can move synthetic equity prices long before Hong Kong opens. Thin overnight liquidity can push the perpetual away from the last observable cash-market price.

Funding, mark prices, leverage limits and margin requirements are therefore not secondary settings. They are the mechanisms holding the synthetic market together.

That is why the September 10 announcement is more significant than another batch of contract specifications.

Binance spent much of 2026 building out its TradFi perpetual catalogue. It is now increasingly showing what comes next: continuously tuning the machinery needed to keep a 24/7 leveraged synthetic equity market functioning when the traditional assets underneath it were never designed to trade that way.
