The U.S.-Dollar Supranational Zero-Coupon Curve

Available as: PDF

The author describes the construction of the U.S.-dollar-denominated zero-coupon curve for the supranational asset class from 1995 to 2010. He uses yield data from a cross-section of bonds issued by AAA-rated supranational entities to fit the Svensson (1995) term-structure model. Results show the expected pattern of interest rates over the U.S. business cycle. The author computes the spreads relative to the U.S. Treasury zero-coupon yields data of Gürkaynak, Sack and Wright (2007). The average spread for this period is equal to 44 basis points; it increases during recessions and narrows during expansions. Also, the slope of the term structure of spreads shows a countercyclical pattern.
