Who they are
FICC's Government Securities Division, a subsidiary of the clearinghouse DTCC.
What they do
It clears U.S. Treasury trades, acting as the choke point for the world's biggest market in government debt.
How it works
By December 2025 it was handling about $13.2 trillion in average daily volume (per DTCC's year-end disclosure), with essentially all Treasury transactions passing through it.
Why it matters
It's core financial plumbing; controlling the pipe that clears the deepest government-debt market in the world is enormous quiet leverage.
