Net bank position as % of open interest
Net position is long minus short contracts held by banks, as a share of the market's total open interest. Negative bars mean banks are net short. When U.S. and Non-U.S. banks lean the same way, the bank sector as a whole is positioned in that direction.
Gross vs net bank share of open interest
Horizontal: how much of open interest banks hold in total (long + short). Vertical: how one-sided that is (|long − short|). Points near the dashed diagonal are one-directional books. Points far below it carry large gross positions with little net exposure, typically relative-value or hedged books, so reading a directional bank view into them is misleading. Some markets sit near the diagonal structurally, so compare a market with its own history rather than with others.
Average gross position per bank (contracts, log scale)
Average gross position (long + short) per reporting bank, on a log scale. It shows concentration: a handful of U.S. banks often carry far more per house than the many Non-U.S. banks. Markets where CFTC withholds the bank count are left out.
