DTCC GCF Repo Index®

a service offering of DTCC Solutions LLC

The DTCC GCF Repo Index is the only index that tracks the average daily interest rate paid for the most-traded GCF Repo contracts for U.S. Treasury and mortgage-backed securities issued by Fannie Mae and Freddie Mac. These are instruments that clear at the Government Securities Division (GSD) of the Fixed Income Clearing Corporation (FICC). The index’s rates are par-weighted averages of daily activity in the GCF Repo market and reflect actual daily funding costs experienced by banks and investors, per underlying asset class.

What is the composition of the DTCC GCF Repo Index?
The DTCC GCF Repo Index is composed of the following two most traded GCF Repo-eligible CUSIPs: (1) U. S. Treasury < 30-year maturity (371487AE9); and (2) Fannie Mae and Freddie Mac Fixed Rate MBS (371487AL3). The securities in the computation of the index include only overnight transactions that are completed on a daily basis for each of the two CUSIPs.

Securities not in the computation of the index include term trades (transactions where settlement date equals trade date plus two business days or greater) and forward start repos.

The volume is reflective of the repo and reverse transactions that are dealer executed and does not include the inter-dealer broker portion of the transactions.

For each of the CUSIPs a weighted average rate is calculated on a daily basis using the following formula:
Par weighted rate = SUM (for each overnight trade: Dollar amount*GC rate/SUM (for each overnight trade: Dollar amount) .

Do the charts show the rates for more than just the previous day?
Yes. You can chart rates for the previous day, week, month or the previous 12 months.

Do the charts show the value of the repo transactions?
In addition to the rates, the charts also show the par value, that is, the total nominal value of GCF Repos submitted each day for clearing to Fixed Income Clearing Corporation. You can view par value by day, week, month or year.

What is a repo (or repurchase agreement)?
A repo is generally a form of short-term secured loan that involves the sale of a security and the subsequent repurchase, typically on the same day, of the same security.

What's a GCF (General Collateral Finance) Repo?
DTCC's Fixed Income Clearing Corporation developed the GCF Repo so that dealers could trade general collateral repos, based on rate, term and underlying product throughout the day without requiring intra-day, trade-for-trade settlement on a delivery-versus-payment basis.

What's the data source?
DTCC's Fixed Income Clearing Corporation, which serves as the clearing house for trading in U.S. government securities.
