Get ready for a flood of Treasury bills
TGA rebuild drains reserves and RRP
As Washington negotiators inch toward an inevitable eleventh-hour compromise to suspend the statutory debt ceiling until 2025, wholesale money markets are bracing for the liquidity hangover. Over the past five months, the Treasury’s inability to issue debt forced Janet Yellen to drain the Treasury General Account (TGA) from $500 billion to near zero, injecting a massive wave of synthetic liquidity into commercial bank reserves. Once the debt ceiling is officially lifted, the polarity reverses violently: the Treasury must immediately replenish its depleted cash balance by launching an unprecedented deluge of fresh Treasury bills, with issuance projected to exceed $1 trillion within ninety days. Get ready for a liquidity contraction that will test the plumbing of global finance.
The sheer scale of the coming bill flood is historic. Sucking $1 trillion in cash out of the financial system in a single financial quarter creates an immediate competition for wholesale liquidity.
The Battle for Wholesale Cash
The critical structural question is where the cash to absorb these bills will originate. If money market funds pull cash out of the Federal Reserve’s $2 trillion Overnight Reverse Repo Facility (ON RRP) to buy Treasury bills offering attractive 5.3 per cent yields, the liquidity impact on commercial bank reserves will be relatively neutral.
If, however, money market funds demand higher yields and the bills are absorbed by commercial banks, corporations, and institutional investors pulling money out of commercial bank deposits, bank reserves will plummet. In that scenario, bank reserves could contract by hundreds of billions, severely exacerbating the deposit flight and margin compression that triggered the March regional banking crisis.
The Spreading Hangover
Furthermore, an issuance flood of this scale will aggressively bid up short-term borrowing costs across the economy. Primary dealers will have to dedicate scarce balance-sheet capacity to warehouse billions in government paper, widening bid-ask spreads and draining market-making liquidity from corporate credit and mortgage markets.
The resolution of the debt ceiling will eliminate default risk, but it will usher in an acute liquidity drain. Raising the debt ceiling is treated by politicians as the end of a crisis, but for financial markets, the post-deal bill deluge represents an immediate $1 trillion liquidity withdrawal that will amplify the Fed's quantitative tightening and test the fragile plumbing of regional banking.
