JPMorgan, Jane Street, & the Bank Balance Sheets Behind Non-Bank Liquidity

A quiet decision by JPMorgan to trim Jane Street’s financing lines reads, on the surface, as a footnote in a strong year for both firms. Through the Imagery–Anxiety–Infrastructure lens it marks something larger: the market-making of the world’s reserve asset has migrated to firms sitting outside the regulated dealer perimeter—and the bank balance sheets that fund them now carry competitive as well as prudential reasons to step back, precisely when Treasury liquidity is most fragile.

The dollar’s primacy has always rested on the unmatched depth of its government-bond market. That depth is increasingly rented from firms the official sector neither backstops nor fully sees. JPMorgan has just repriced the rent—and the question the trim raises is what happens the day every landlord wants to.
