The current borrow rate on TQQQ at IBKR is around 2-2.5% for May MTD. As a SYEP enrolee I get half that when my shares are borrowed- I have no qualms with this. What I am concerned about, however, is why the total rate is so low when considering the expense ratio and cost-of-leverage tailwind that going short would provide. The yearly cost of about 12% due to the fed funds rate being 5.00 - 5.25% spread for banks .95% expense ratio is directly subtracted from the NAV daily thus benefiting the shorts. I wont even get into compounding decay since this isn't meant to be held longer than daily, but my point being is IBKR should be paying a lot more for my borrowed shares (Karen moment)
