New Endpoint: /v5/account/no-convert-repay

Dear Traders,

1. Bybit will introduce a new endpoint – POST /v5/account/no-convert-repay – which allows users to repay only positive assets (ie, where walletBalance > 0).

This new endpoint is similar to the existing POST /v5/account/repay (https://bybit-exchange.github.io/docs/v5/account/repay) endpoint, but only repays assets in the same currency, avoiding asset conversion or repaying using assets which already have a negative balance.

Request Parameters

Parameter  Required  Type    Description
coin       false     string  Coin name (uppercase only)
amount     false     string  Repay amount. If the coin is not specified, the amount must also be omitted.

Release Schedule
Testnet: October 30, 2025
Mainnet: November 3, 2025

2. These two APIs are changing from being asynchronous to returning synchronously.
POST /v5/account/repay
POST /v5/account/no-convert-repay

We will add "SU" and "FA" enums to the response parameters to reflect this.
Parameter Type Comments
result array Object
> resultStatus string
P: Processing
SU: Success
FA: Failed

Dear Traders,

To enhance system performance and stability, we are planning the following update to the OpenAPI endpoint /v5/market/instruments-info (category = option):

PreLaunch (about to go live)
Trading (currently trading)
Delivering (in the delivery phase)

📈 Background:
We have observed a recent increase in transactions per second (TPS) on this endpoint. As it currently accesses the database in some scenarios, this adjustment is intended to improve performance and stability under high-load conditions going forward.

Dear Traders

We’re enhancing the Unified Trading Account (UTA) Manual Borrowing experience. A new fixed-rate borrowing option will roll out in phases starting Dec 08, 2025 (the full launch date may vary based on readiness).

Please refer to:

Dear OpenAPI Users,

Following our earlier announcement https://t.me/Bybit_API_Announcements/383 (https://announcements.bybit.com/en/article/bybit-uta-manual-borrowing-fixed-rate-option-coming-soon-bltbc3b81ddfc8563cd/) regarding the upcoming introduction of the UTA Manual Borrowing Fixed-Rate option, we would like to provide important clarifications for OpenAPI users regarding the December 8 release version.

Key Notes for OpenAPI Users:
1. Borrowing via OpenAPI endpoint (https://bybit-exchange.github.io/docs/v5/account/borrow) will support floating-rate borrowing only in this release.
2. Repayment behavior via OpenAPI endpoints (https://bybit-exchange.github.io/docs/v5/account/no-convert-repay or https://bybit-exchange.github.io/docs/v5/account/repay):
The system will repay floating-rate liabilities first, followed by fixed-rate

Upcoming Feature: Auto-Repay Mode for Spot Margin Trading

Dear Traders,

We are pleased to announce the upcoming launch of the Auto-Repay Mode for Spot Margin trading, along with two new API endpoints that allow users to configure and query this feature.

New Endpoints:
1. Set Auto-Repay Mode
POST /v5/spot-margin-trade/set-auto-repay-mode
Configure whether to enable or disable Auto-Repay for a specific currency.
Documentation: https://bybit-exchange.github.io/docs/v5/spot-margin-uta/set-auto-repay-mode

2. Get Auto-Repay Mode
GET /v5/spot-margin-trade/get-auto-repay-mode

Upcoming Update: Fee Rate Endpoint Infrastructure Optimization

Dear Users,

To improve system stability and reduce the load, we will update the Fee Rate Query API underlying service.

GET /v5/account/fee-rate
Documentation: https://bybit-exchange.github.io/docs/v5/account/fee-rate

Effective Date: January 20, 2026

After the switchover, the fee rate query will no longer be returned in real-time. As a result, responses may experience a slight additional latency of approximately 10–20 ms. Other functionalities and response structures remain unchanged.

This change helps enhance overall system performance, stability, and reliability for all users.

If you have any questions or feedback, please feel free to contact us.
