It's incredible how this comment got a bunch of replies not understanding the question.
Explanation: Tether is not holding a stack of paper bonds in a safe. They must use some broker (or similar) to operate and hold the treasuries for them. And they are hiding how this is working. So the parent's question is who do they (Tether) hold it (treasuries) through (as in what broker/investment bank/whatever).
My answer is nobody outside Tether knows. And they are one of the dodgiest companies out there. We are totally audited, bro, trust me. They could be doing leveraged investments. Or they could just be Madoff 2.0. Nobody really knows. And the US government seems to be looking the other way because they are desperate for any buyers of treasuries.
Exactly. I got this pointed out by one of the old school finance guys I've followed for years on Twitter/bsky; if you're a market participant of that size, other participants should expect to know who you are. If only because someone buying a billion dollars of bonds a week is useful to know if you want to unload some bonds.
USDC by contrast are open in their holdings, through Blackrock.
Large invisible "dark matter" financial holdings are the sort of thing that blow up badly during a financial crisis.
