Repo Rate Spike: A ‘Tail’ Of Low Liquidity

Markets can prove interesting when the price of liquidity abruptly increases and high yield is no longer the highest-yielding investment

Banks’ “reporting” dates are known inflection points in the short-term funding markets and typically fall at the end of the month, quarter, and of course the year. But periodically, the 15th of the month is also a pressure point. Such was the case this past Monday when a short-term funding rate that had been hovering around 2.21% soared as high as 10%.

The funding market succumbed to a trifecta of pressures:

  1. Payments on corporate taxes were due on 15 September, leading to high redemptions of more than $35 billion in money market funds.
  2. Cash balances increased by an additional $83 billion in the U.S. Treasury general account, which reduces excess reserves and simultaneously acts to reduce the aggregate supply of overnight liquidity available in funding markets.
  3. Dealers needed an additional $20 billion in funding to finance the settlement of recent scheduled U.S. Treasury issuance.

None of these pressures was extraordinary or unforeseen, but together they had an extraordinary impact.

At the source: the Fed’s lower reserves

In our view, the repurchase (repo) market, where banks and broker-dealers can obtain overnight collateralized loans from intermediaries, is a critical barometer of the health of the financial markets. This week’s events demonstrated that the funding markets overall are increasingly susceptible to large changes in flows from the supply side even if the demand for funding does not change much.

On September 15, as so many institutions needed funding, repo rates climbed well above the fed funds upper-end target at the time of 2.25% to briefly touch 5%. The following day, cash repo markets traded as high as 10% for those looking to finance agency mortgage positions overnight. Later that morning, the Federal Reserve Bank of New York acknowledged the pressures and conducted its first Open Market Operation (OMO) in more than a decade to add reserves to the funding markets that were clearly in need of the liquidity. Subsequently, after its meeting Wednesday, the Federal Open Market Committee (FOMC) announced a cut in the interest on excess reserves (IOER) of 0.30% – five basis points more than its cut in the fed funds rate – providing some relief to the upper bound of money-market yields. Even after this, however, funding costs have remained elevated, which suggests that additional steps are likely to be considered, including term funding facilities.
