JPMorgan Chase & Co (JPM.N) has become so big that some rival banks and analysts say changes to its $2.7 trillion balance sheet were a factor in a spike last month in the U.S. “repo” market, which is crucial to many borrowers.
Analysts and bank rivals said big changes JPMorgan made in its balance sheet played a role in the spike in the repo market, which is an important adjunct to the Fed Funds market and used by the Fed to influence interest rates.
Without reliable sources of loans through the repo market, the financial system risks losing a valuable source of liquidity. Hedge funds, for example, use it to finance investments in U.S. Treasury securities and banks turn to it as option for raising suddenly-needed cash for clients.
Publicly-filed data shows JPMorgan reduced the cash it has on deposit at the Federal Reserve, from which it might have lent, by $158 billion in the year through June, a 57% decline.
