AMERIBOR

Introduced by Richard Sandor, who is known for creating interest-rate futures in the 1970s, Ameribor is determined on the American Financial Exchange.^[1][4] This is a platform where banks lend through mutual credit lines.^[1][5]

Ameribor serves as a competitive alternative to the Secured Overnight Financing Rate (SOFR), which only provides an overnight rate.^[1]

Ameribor is favored by smaller banks as it accurately represents the fund trading costs for banks outside the Federal Reserve's primary dealers. These banks often lack access to repo markets.^[1]
