Operating Policy
Statement Regarding Treasury Securities Operations
May 13, 2021

Effective May 14, 2021, the Open Market Trading Desk (the Desk) at the Federal Reserve Bank of New York is making technical adjustments to its purchases of Treasury securities conducted on behalf of the Federal Open Market Committee (FOMC). Specifically, the Desk is updating the maturity ranges for its purchase sectors and the associated sector weights to ensure that the allocation across sectors remains roughly proportional to Treasury securities outstanding in those sectors.

Issuance patterns of Treasury securities have changed over the past year, resulting in modest shifts in the distribution of Treasury securities outstanding. As a result, the Desk will segment its purchase sectors for longer-dated securities into additional maturity ranges to reflect last year’s introduction of a new benchmark security. The Desk will also update associated sector weights.

These updated allocations represent a modest shift in the distribution of purchases the Desk has been using since June 2020, when allocations were last updated. As a result of these changes, the allocation across the 7- to 30-year nominal coupon maturity range will increase by 3 percentage points, in line with shifts in the distribution of Treasury securities outstanding. The allocation to the shortest nominal coupon sectors and Treasury inflation-protected securities (TIPS) will decrease modestly. Securities ultimately purchased in each sector will depend on the offers submitted by counterparties in each operation, which are evaluated based on their proximity to prevailing market prices at the close of the operation, as well as measures of relative value.

In general, the Desk will distribute monthly purchases across eight different sectors based roughly on the 12-month average of the proportional par amount of Treasury securities outstanding in each sector. The table below includes the specific sectors the Desk will use and their sector weights based on 12-month average amounts outstanding as of the end of April 2021. Purchase allocations are subject to change, including as needed to sustain the smooth functioning of the Treasury market, and will be updated periodically.

SECTOR 0-2¼ yrs 2¼-4½ yrs 4½-7 yrs 7-10 yrs 10-22½ yrs 22½-30 yrs 1 - 7½ yrs 7½ - 30 yrs
SECTOR WEIGHT 31% 21% 15% 8% 7% 10% 5% 3%
* For determining sector weights, the on-the-run 7-year note will be considered part of the 4½ to 7-year sector and the on-the-run 10-year noted will be considered part of the 7 to 10-year sector.
** The TIPS sector weight is based on unadjusted par amounts.
