Jeffrey Roach, an analyst at LPL Financial, said in a note that the sudden volatility in currency markets "may have contributed to the Fed's decision to cut interest rates ahead of its regular meeting on September 18". Investors should be aware that a well-functioning dollar funding market is essential to underpinning the financial system and that exacerbating currency volatility is a risk. Mr. Roach advised investors to "watch the Fed's use of liquidity swaps in the near term" because an increase in operations "could indicate heightened uncertainty among central bankers".
