This link has broken since the GFC, with banks (especially the largest 5 banks decreasing the number of physical outlets by about 15%) while growing deposits by more than 250%,
Isn’t the growth in deposits for the larger banks mostly from acquisitions (during the GFC) and not organically? The organic deposit growth doesn’t look all that impressive to me.
If you want more "color" (probably more than you asked for).

Like usual, you are correct and if you decompose into periods since the GFC, the early upheaval period was accompanied by a relative bump in deposits for the big boys as the FDIC margin (and patience) was wearing thin. However, deposit growth has been relatively steady overall

The following shows some details related to the recent deposit growth, the competitive dynamics and how (big) banks have many internal levers to keep customers happy:

If you believe wabuffo and think that the recent rise in deposits has been correlated (caused by?) rising liabilities then the answer may reside in the ability to answer the following questions: 1-Deleveraging, what deleveraging? and 2-Where are we in the cycle?
For question #1, the following gives an interesting perspective:

For question #2, if you are agnostic about exactly timing the cycles and/or if you can opportunistically build-up your position as a privileged insider and deep pocketed investor when the sun don't shine, you can still consider the option of focusing on the US "market leaders" and the "resilients".
