When funding exceeds the spread

The seed asked this module to make funding visible, because it hides: a rate quoted as 0.01% per eight hours reads like nothing and annualises like a serious cost. This lesson does the arithmetic that the quote obscures.

The arithmetic funding hides

Funding of 0.01% paid three times a day is 0.03% daily - which annualises to about 10.95% a year, a rate that would be a headline cost anywhere else on the platform, quoted as a number that looks like a rounding error. And funding runs far higher than 0.01% in crowded markets: sustained rates several times that turn a held leveraged long into a position bleeding double-digit annualised percentages to the shorts, invisibly, every eight hours. The spread was paid once; funding is paid 1,095 times a year - the seed's warning, in numbers: funding silently exceeds the spread, usually within weeks.

Why it hides so well

• The unit is tiny and frequent: a per-eight-hour percentage reads as trivial and accrues relentlessly - the psychological opposite of a visible fee.
• It is not on the trade ticket: funding debits and credits arrive on a schedule, separate from the position's price P&L - easy to overlook until they dominate.
• It swings and can pay: sometimes funding is received, which trains inattention - until the regime flips and the same position pays what it used to earn.

The two audiences

For those who can access perpetuals: funding is the standing cost, the perpetual's answer to the futures roll - it belongs in every held position's cost estimate at its annualised rate, and a strategy that holds through high funding must clear it exactly as a futures strategy clears the roll. For the spot holder who cannot: funding is a signal - extreme rates mark the crowded leverage that precedes cascades, readable on any funding chart, a free read on the pressure in the layer that moves spot. Either way, made visible - which is the lesson the seed asked for.
