NY Federal Reserve Repo Operations - What is it? In the news, September 20, 2019

NY Fed added an additional $75 billion to the bank lending markets Friday, bringing its four day total to just over $275 billion.
This was after repos surged between Monday afternoon and Tuesday morning
Repos refer to repurchase agreements. This is the cost of borrowing cash in exchange for US Treasuries.
The rate surged to as high as 10 percent, an increase of more than fourfold overnight Monday.
Federal Reserve Chairman Jerome Powell addressed this weeks spike during his press conference on Wednesday. There he noted that the impact of tax payments and bond purchases on the systems 24 primary dealers was "stronger than expected" and "surprised a lot of market participants"
Some economists even suggested that the weekend attack on oil production facilities in Saudi Arabia could have played a role in increasing demand for cash by foreign banks with exposures to the Middle East.
In a repo trade, Wall Street firms and banks offer US Treasuries and other high-quality securities as collateral to raise cash, generally overnight, to finance trading and lending activities. The following day, borrowers repay their loans plus some nominal rate of interest.
Bank reserves have been falling since 2015 when the Fed started raising interest rates. Reserves started to fall faster when the Fed began cutting its bond portfolio in 2017. Policymakers wonder if the Fed cutting rates and no longer allowing bonds to roll of its balance sheet is enough to stop the downward drift in reserves, which are the main source of funding in liquidity markets like repo.

That's what we all want to know! Perhaps look into the primary lenders with the Fed and see if any have struggled to maintain reserve balances?
