What is the funding rate for stock derivatives? Why is it said to be the holding cost that ordinary traders are most likely to overlook?
When trading stock derivatives contracts, most people only focus on the opening price, leverage, and transaction fees, while neglecting the third cost: the funding rate. It is a fee that is periodically paid between long and short positions, with the specific settlement cycle and rate level determined by the rules of each exchange—when your position is opposite to the market direction, you have to pay the counterparty, and when your position aligns with the market direction, the counterparty pays you. In a one-sided market, this fee may significantly increase. This article clarifies the mechanism of the funding rate, how to read it, and its relationship with the position direction.
