How this is measured. The US banking system figure is each bank's net interest margin weighted by its average earning assets, so a large bank counts in proportion to its size. The average bank figure is the simple average of each bank's own ratio, so every bank counts the same. Both cover every US bank and savings institution that filed a call report for the quarter. A quarter appears once enough banks have filed to describe the industry; until then the newest quarter shown is the one before. A median is not published here yet.
