OKX charged the least of the three venues we track to borrow dollars on margin in the 05:25 UTC read on Oct 18, at 3.5% a year for USDT. Binance charged the most at 4.71%, and Bybit's 3.92% matched the median.

Dogecoin showed the widest gap across 15 assets. On OKX, traders long $DOGE perpetuals paid 10.95% a year in funding, a fee that goes to the short side. Borrowing DOGE on the same venue cost 1% a year.

That left a recorded 9.95% spread between the two rates, the largest on the board in this read.
