Before discussing funding, let's first understand the rate.
The annualized rate is simply the current rate extrapolated over a year. The rate changes each period, so don't treat it as the actual cost for a year.
The rate only indicates an imbalance between supply and demand in the futures market; it doesn't tell you how spot buying is doing.
Cross-checking multiple data points is more reliable than looking at just one, but even a wide range of indicators can't provide a definitive answer.

For reference only. Trade at your own risk.
