“Uncertainty over the future of interest rates is clearly starting to show up in the CUSIP data set, particularly as we start to see some volatility in the monthly activity,” said Gerard Faulkner, Director of Operations for CUSIP Global Services. ” While the Fed has signaled that it will raise rates again in December, it is not yet clear what’s in store for 2019, so we expect to continue to see a fair amount of volatility in our monthly CUSIP request volumes.”
