This is called the "Steepener" trade and refers to a mean reversion in the yield curve. From current level of (-38 basis points, or -0.38%), I'm targeting a move back to 1.00%, or ~70bp, risking down to about (-45bp), or about (-13bp) downside.
Yield curve steepeners seek to gain from a greater spread between short- and long-term yields-to-maturity by combining a “long” short-dated bond position with a “short” long-dated bond position, while a flattener involves sale of short-term bonds and purchase of long-term bonds. - CFA Institute
