Perpetual futures never expire, so exchanges use a funding payment to tether the perp price to spot. Longs pay shorts when funding is positive, shorts pay longs when it is negative, and it settles every eight hours on most venues.
Every eight hours on most venues, which is three times a day, and a position is only charged if it is open at the settlement instant. Closing a minute before settlement pays nothing; opening a minute before pays the full interval. Some contracts settle hourly, and those are the ones where a rate that looks small is not.
It is a payment, not a return. Negative funding means shorts pay longs, so a long collects -- and the reason it is negative is that the market is crowded on the other side, which is a statement about positioning and not about direction. The payment is real; the position risk it comes attached to is real too and is usually larger.
Because funding is set per venue from that venue's own basis between perp and spot, and the crowds differ. The gap is the whole reason this site exists: the same contract can pay on one venue and cost on another at the same moment, and holding it on the wrong one is a cost with no view attached.
Yes, quietly. Funding is deducted from margin rather than from an unrealised profit, so a position held through several settlements drifts toward liquidation while the price has not moved at all. It is the mechanism behind most of the accounts of a position that went sideways and still lost.
Read it as a daily figure rather than per interval, because that is the timeframe positions are held on. A 0.01% print is the ordinary resting rate and costs 0.03% a day. A 0.1% print is 0.3% a day, which on a ten-times position is 3% of margin every day before a single trading fee.
