The U.S. Treasury Department has sparked a debate about reducing auction sizes to curb yields.

The U.S. Treasury has sparked debates about the auction of government notes and bondsan auction scale for government notes and bonds that will only continue to grow, which has long been a iron law in the worlds largest bond market. The Treasury has made slight adjustments to its quarterly debt issuance policy statement, changing its assessment of potential future increases in coupon-bearing securities auctions to potential future adjustments. Some traders speculate that officials may consider reducing the auction size of the longest-term debt and concentrating any future issuance increments on shorter-term and medium-term varieties, which are less costly.
