The Fed, Treasury and liquidity

A reader asked me to please explain why liquidity is rising despite the Fed hiking rates and shrinking its balance sheet (QT) by more than $1.7 trillion.

We will try to avoid the technical jargon and stick to the basics. But it’s not always an easy concept to explain or grasp.

What is liquidity?

Liquidity is not the same as money. It is more closely related to other side of the balance sheet and is best described as the “ease of financing” or availability of credit in financial markets. It includes access to credit from the domestic banking system and bond markets, as well as international financial markets.

In Reminiscences of a Stock Operator Jesse Livermore describes the operation of the Money Post on the floor of the exchange, where brokers borrowed money overnight to finance their stock operations. We have included an excerpt where he describes the impact of tight liquidity leading up to the crash of 1907. It is worth reading: The Money Tree | Jesse Livermore

How do we measure liquidity?

We use several indicators to measure liquidity in financial markets. These include:

Commercial Bank Reserves at the Fed

Commercial bank reserves spiked up in March 2023 after the Silicon Valley Bank (SVB) debacle, when the Fed introduced the Bank Term Funding Program (BTFP). Reserves continued to climb steeply until February 2024, when inflation reared its head, before falling sharply in March and April during the tax payment season.

Chicago Fed Financial Conditions Index

The Chicago Fed Financial Conditions Index is an excellent measure of financial market liquidity, though data is normally a week behind that of bank reserves.

Moody’s Baa Corporate Bond Spread

Moody’s Baa corporate bond spreads are a good indicator of credit availability in bond markets. The spread measures the premium that low investment grade corporate borrowers have to pay over the risk-free Treasury rate.

We even use Bitcoin as the “canary in the coal mine”. Cryptocurrencies are the most liquidity-sensitive assets in financial markets and normally the first to show signs of stress.

Bitcoin climbed steeply from November ’23 until early March ’24 before stalling in March-April. Its rise in May heralded a recovery in financial market liquidity.


How the Fed and Treasury influence liquidity

The most obvious way that the Fed influences liquidity is by purchasing or selling Treasury and Agency securities in financial markets.

In April 2020, the Fed purchased almost $3 trillion in securities, expanding its balance sheet (blue below). We can also see that Treasury took advantage of these Fed purchases, issuing $1.4 trillion more in securities than it needed to fund current expenditure. The surplus shows in the TGA account at the Fed (red below) and had the effect of partially offsetting the Fed’s injection of liquidity.

In 2021, Treasury slowed their issuance of securities, as they neared the debt ceiling, and started to draw down on their TGA account at the Fed (red above). This amplified Fed QE (blue) as it also injected liquidity into financial markets. The Fed did their best to offset this by borrowing in financial markets through overnight reverse repo operations (green above) mainly from money market funds which normally invest in T-Bills and other short-dated securities.

In late 2022, the Fed announced it was going to gradually reduce its balance sheet as securities matured. The blue area below zero is referred to as quantitative tightening, or “QT”. Since then, total assets at the Fed have shrunk by roughly $1.7 trillion. Treasury also increased net issuance and started to rebuild their TGA account balance (red) above. But the Fed was again able to offset this by lowering rates offered on reverse repo and running its RRP liabilities (green) down from almost $2.4 trillion to just $371 billion at present.

The net impact of the combined operations is shown by the blue line below. The massive combined monetary easing lasted until early 2022, when tightening commenced. But tightening ended after the March ’23 banking (SVB) crisis, with the Fed injecting liquidity to prop up financial markets until March ’24. By March, inflation was starting to rebound and the Fed may have realized that they had over-egged the pudding.

The abrupt fall in liquidity in March-April was evident not only in bank reserves but in Bitcoin and in the stock market.


Liquidity is again rising — as shown by the the rise in Bitcoin and the fall in Chicago Fed Financial Conditions Index. Stocks and bonds are likely to rise as a result.


There are further factors that affect financial market liquidity in the US. This can include monetary easing by foreign central banks. The PBOC may inject liquidity into financial markets in Beijing or Hong Kong but the net result may ease financial conditions in New York if US T-Bills offer higher rates of return than the equivalent security in China.

We have also seen Treasury Secretary Janet Yellen change the mix of Treasury issuance in order to reduce the impact on financial market liquidity. Reducing the amount of longer maturity Treasury notes and bonds and increasing issuance of shorter-term T-Bills also helped to boost liquidity. T-Bills are the most liquid asset on the planet, with almost infinite demand. Holding a 3-month T-Bill is like holding Dollars — they have no default or rate risk — but you get a 5.0% return on top. So issuing more T-Bills has limited impact on short-term rates, while issuing less 10-year Notes , for example, will lower long-term yields when demand exceeds supply.
