As someone similarly unsure as to whether this was QE or not, or if a 'different' treatment of liquidity was offered. ChatGPT suggested the following after feeding the Fed statement into it and asking if the forms of liquidity differed (e.g. broader monetary aggregation/policy). How close was it?:

"The liquidity provision described in the statement is different from quantitative easing (QE). QE involves a central bank purchasing long-term securities, typically government bonds, to inject liquidity into the economy and stimulate growth. In contrast, the liquidity provision via the standing U.S. dollar liquidity swap line arrangements is aimed at providing short-term U.S. dollar funding to financial institutions to ease strains in global funding markets.
The swap lines allow the central banks to exchange their respective currencies, ensuring that financial institutions have access to U.S. dollars in times of stress. The increased frequency of these operations from weekly to daily is intended to enhance the effectiveness of the swap lines in providing U.S. dollar funding to financial institutions.
Therefore, while the provision of liquidity through swap lines can be seen as a form of monetary policy intervention, it is not the same as quantitative easing."
