Deep Tide TechFlow News, on May 13, starting from May 13 (Monday), Backpack Exchange announced the introduction of a unified +11% annual benchmark interest rate in the funding rate calculation formula for its perpetual contracts. This update aims to align with the funding rate structure of mainstream derivatives exchanges in the industry, while enhancing the overall liquidity and trading activity of the market.

The new mechanism does not change the original calculation logic of the funding rate, but instead optimizes the funding rate environment further by setting a sustained positive bias, which is particularly beneficial for Delta-neutral strategy participants, providing them with more attractive funding rate arbitrage opportunities.
