SOFR Swaps – Block Trades and Fannie Mae Issuance

SOFR Swaps Are Trading More Frequently

Thanks to our SDR Alerts, I get an email every time SOFR or SOFR Basis trades. Over the month of October 2018, the frequency of these emails has been steadily increasing into my inbox:

I make that 12 swaps so far in the month of October.

Is that a significant move? It’s hard to say really. These are early days, with a total of just $500m traded in the basis during October. So there is a lot of price-forming still to go – especially when a single 2 year trade has potentially just doubled the total amount of SOFR DV01 ever traded!
