Memorial Day: The debt deal is done. Now comes the bill

Political theatre in Washington has concluded with its customary anticlimax, but the financial reckoning is only just entering the order books. With the suspension of the statutory debt ceiling agreed on 27 May, the Treasury can finally cease its extraordinary accounting manoeuvres and address the depleted state of its operating balances. The cost of avoiding default, however, will be borne directly by wholesale funding markets as the Treasury General Account undergoes a violent reconstitution.

The Cash Vacuum

To rebuild cash reserves toward the targeted $600 billion, Janet Yellen’s department must unleash a torrent of short-dated paper. Sucking hundreds of billions in unencumbered liquidity out of the financial architecture within weeks will test the absorptive capacity of prime money market funds and primary dealers alike. If the supply is absorbed by drawing down the Federal Reserve's overnight reverse repo facility, the broader monetary shock will be cushioned; if it drains bank deposits, the regional banking sector will face an acute secondary tremor.

The debt ceiling farce may have averted an unthinkable technical default, but the sovereign cash rebuild will extract a punitive liquidity toll that compounds quantitative tightening at the worst possible moment.
