U.S. Debt Ceiling Deal Nears: What's Next for Liquidity?

 | May 30, 2023 06:11

Assuming no last-minute surprises, it seems like we might be getting a debt ceiling deal in the US, which means you should be prepared to get overwhelmed by financial commentators' takes about 'liquidity.'

The very unnuanced story goes like this: The government needs to rebuild its Treasury General Account (TGA) buffer at the Fed, so it issues bonds and it drains 'liquidity' from the 'system.'

And here, I can picture you guys thinking: What the heck does that mean? And is it true?

Monetary mechanics are best understood through the use of good old T-accounting.

In our stylized model, we will assume 5 players (government, Fed, commercial banks, money market funds, and households) and mimic each monetary transaction – colors will help you "follow the flow of money."

Before we go to the post-debt-ceiling TGA, rebuild, let's start with bond issuance to fund deficit spending.

BLUE: The government spends $100 (deficit spending), and it injects net worth into the private sector (household’s equity) and so households now have $100 more bank deposits. These bank deposits end up as a liability for banks, and the corresponding increase in assets is a boost of $100 in bank reserves.

GREEN: The government "has" to issue $100 in bonds to "fund" its deficit spending, and banks use some of their increased reserves to buy $100 in bonds.
