bStocks as Binance collateral: VIP 0–2 must pass a questionnaire first

A VIP 0–2 account that opens Binance's margin trading page to move bStocks in as collateral is met by the Suitability Assessment Questionnaire before anything else. The help page is explicit that these accounts must pass the questionnaire before transferring bStocks in as collateral or trading bStocks on margin. Without a pass, the related margin features stay unavailable.

Behind that gate is a change on Binance Margin, which has started accepting some bStocks as collateral, and a set of risk-control rules that VIP 0–2 accounts carry on top of the questionnaire. Binance published this FAQ on 3 July 2026, and the English page was last updated on 24 September.

bStocks on Binance Margin: collateral only, no borrowing for now

Binance Margin now supports some bStocks tokens as eligible collateral assets. They can be used as collateral in Cross Margin, Portfolio Margin and Portfolio Margin Pro, by eligible users in permitted jurisdictions. The current list is on the Margin Data page.

One answer on the page needs pulling out on its own: "Borrowing is not currently supported for bStocks tokens. They can only be used as collateral assets." For any future change, the page points to official Binance announcements. The purpose it gives for posting bStocks is "to enhance capital flexibility".

A separate point is easy to mix up with this one. The spot token itself has no built-in leverage and can't be shorted. Posting the token in a margin account as collateral is another matter, and it's the one dealt with here: the leverage comes from the account, not from the token.

The VIP 0–2 Suitability Assessment Questionnaire: when it appears and how many failures lock you out

Binance frames the rule as protecting user assets and meeting regulatory requirements: VIP 0–2 users must pass the questionnaire before they can use bStocks as collateral or trade bStocks on margin. For VIP 3 and above it's optional. If your level drops below 3, you have to complete the questionnaire to keep going.

On what a pass is worth, the page has one line: "Once passed, the questionnaire is valid." The retry rules after a fail are written as four bullet points; merged into two rows, they look like this:

Failed attempts	Retry rule
1st and 2nd fail	You can retry immediately
3rd fail	Starts a 24-hour cooldown during which you can't retake the questionnaire; once it ends you can try again, and another fail starts a new cooldown, and so on

If you closed the pop-up and want to get back to the questionnaire, there are two ways: it appears automatically when you open the bStocks margin trading page, or you can go straight to binance.com/en/margin/bstocks-quiz.

How Binance sorts your other coins into three liquidity tiers

For accounts holding bStocks as collateral, Binance sorts the other crypto assets in the account into three classes by prudential quality tier, assessed on volatility, liquidity, track record and similar factors.

Tier	Binance's description
High-liquidity assets	Assets with a higher collateral ratio and relatively stable prices
Medium-liquidity assets	Assets with a moderate collateral ratio and larger price swings
Low-liquidity assets	Assets with a lower collateral ratio and significant price swings

The table isn't fixed. An asset's classification may change over time at Binance's discretion, and the latest classifications are on the Margin Data page. The extra restrictions fall on exactly the medium- and low-liquidity tiers.

Three conditions that must all hold before an account is restricted

Holding bStocks as collateral doesn't mean an immediate restriction. All three of these have to be true at once:

• The VIP level is below 3 and the account holds bStocks as collateral;
• bStocks collateral makes up a significant share of the account's total net asset value after collateral-ratio adjustment;
• Effective leverage on the net exposure to medium- and low-liquidity assets exceeds a specified threshold.

The thresholds and formulas for the last two are in Binance's bStocks Margin Collateral Risk Controls Guide.

Once an account is over those thresholds, the system "may impose restriction measures, including but not limited to" these four:

• No more bStocks can be transferred into the account;
• Buying or borrowing medium- and low-liquidity assets is prohibited (repaying existing liabilities excepted), though transferring in suitable assets to lower liquidation risk is allowed;
• No new futures positions can be opened in the Portfolio Margin account (reducing positions only);
• Auto top-up is paused for bStocks and for medium- and low-liquidity assets.

Look closely at which rule blocks what. High-liquidity assets aren't covered by the ban on buying and borrowing and can still be traded normally. The third rule makes no distinction between tiers, though: once the account is restricted, futures positions in any asset in the Portfolio Margin account can only be reduced, not added to. Binance also specifies that these restrictions apply only to Cross Margin and Portfolio Margin accounts that are VIP 0–2 and hold bStocks collateral. Other margin accounts without bStocks aren't affected, and other sub-accounts can trade as usual.

Getting the restrictions lifted: no application, but you have to act

All restrictions are lifted automatically once the account is back at the required risk level. Binance lists four ways to get there:

• Reduce exposure to medium- and low-liquidity assets: close positions, sell or transfer out, repay liabilities, or close futures positions in the Portfolio Margin account;
• Transfer in high-liquidity assets to improve the collateral mix;
• Upgrade to VIP 3, after which the account is no longer subject to these risk restrictions;
• Transfer out some bStocks to bring their share below the threshold. This one comes with a reminder: "Please ensure your account maintains a safe margin level during the transfer to avoid liquidation."

Take that last reminder seriously. The bStocks are themselves collateral in this account. Whatever you move out takes its collateral value with it, and an account that's already tight may hit the liquidation line first.

Then there's the matter of how you'd know the account has been restricted. An email goes to your registered address both when a risk restriction is triggered and when it's lifted, so keep that address current. The system monitors the account continuously and lifts the restrictions automatically once the trigger conditions no longer hold; there's nothing further to submit.

Four things to think through before posting bStocks as collateral

Collateral ratios change. Different bStocks tokens may have different collateral ratios, and the ratios can be adjusted at any time according to market conditions. Go by the current figures shown on the Margin Data page and related pages.

The index price depends on the US trading session. The index price for bStocks used as margin collateral is calculated differently depending on the US stock market trading session. The details are in Binance's bStocks Tokenized Securities Collateral Index Price Methodology.

There's a maximum collateral amount. Use as collateral is subject to the platform's maximum collateral quantity.

A risk restriction doesn't rule out liquidation. Binance's own wording is: "Risk restrictions do not forcibly close your existing positions. However, forced liquidation may still occur if your margin level breaches the liquidation threshold, regardless of whether risk restrictions are applied on your account."

None of this settles whether stock tokens are safe to hold; the risks of the token itself are a separate question.
