Sounds like the Occupy Wall Street folks have a new ploy that’s catching on via Facebook … inciting bank runs. In the wake of Bank of America announcing $5 ATM fees, a Facebook user riled up followers about “Bank Transfer Day” to dump your existing accounts with large financial institutions for local banks and credit unions. Officially, Friday the 5th is marked for action with other movements sponsored by MoveOn.org and the Progressive Change Campaign Committee. While the number of pledged accounts to vanish is small (in the grand scheme of things), one begins to wonder where the threshold is crossed between banks taking notice and actual distress. After all, it wasn’t too long ago that revised Basel rules allowed banks to dip well below the previous fixed 10% liquidity requirement.
