How do I interpret LCH/CME OIS/IRS pricing data?

Question

I'm trying to use publicly-available OIS/IRS clearing data from CME (ftp://ftp.cmegroup.com/../../irs/) and LCH (http://www.lch.com/en/asset-classes/otc-interest-rate-derivatives/volumes/settlement-prices-swapclear-global#usd) to bootstrap discount and LIBOR curves. The data between the two (for 9/27/17) only seems to line up for a few of quotes; otherwise CME seems to be way off.

How should I interpret this disconnect for the purposes of bootstrapping curves?

Answer 1

The section that refers to USD-LIBOR-BBA 3M looks correct. This shows that CME IRS are marginally higher than LCH IRS. This means that when you bootstrap the curve, the corresponding forward rates will be higher also.

The sections USD-LIBOR-BBA 1M and USD-LIBOR-BBA 6M appear to show the level of 3M-1M and 6M-1M basis swaps respectively. These may help in bootstrapping the forwards for 1M libor and 6M libor. The section USD-LIBOR-OIS appears to show the fed funds -3M libor basis swap , which you also need when bootstrapping, since the fed funds rates are needed to present value the cash flows.
