https://en.wikipedia.org/wiki/Social_Security_Trust_Fund

I put "Trust" in parentheses because, even though it might have actually been more like a trust fund after its initial inception, those who have studied how it has been managed, more or less, in recent years, think of it more as a huge Ponzi scheme. The taxes that one supposedly pays into the Social Security system, on the basis of their income from all of their covered working years, instead of going into a "lockbox" for retirees, is funneled into various other government programs that it wants to keep solvent, perhaps more than they want to keep Social Security solvent.

BTW, to reflect part of what appears in your posted term, Social Security benefits, in the United States, are paid directly to beneficiaries' accounts by the U.S Department of the Treasury.

Benefits are paid with "treasury funds".

Clearly it is the finance-handling wing of the Social Security
Not to be confused wuth THE Treasury, which in most countries refers to the central state finance department
