New York CNN  —  Stamp prices are set to increase — again. The US Postal Service filed a notice with its regulators to increase prices on First-Class “Forever” stamps to 73 cents from 68 cents, marking yet another price hike for the financially beleaguered federal agency. If approved by the Postal Regulatory Commission, the change would take effect in July, raising the cost of mailing services products by nearly 8%. Stamp prices alone have soared 36% since 2019 when they used to cost 50 cents. In a statement, the USPS said that the “price adjustments are needed to achieve the financial stability” sought in the agency’s 10-year plan announced by Postmaster General Louis DeJoy in 2021 to make it more competitive and more modern. “USPS prices remain among the most affordable in the world,” the statement said. Other changes include domestic postcard prices increasing from 53 cents to 56 cents and international postcard prices increasing from $1.55 to $1.65. It’s rare, but not unheard of, for the regulators to decline USPS requests; they did so in 2010. The Postal Regulatory Commission denied a price hike because, according to its statement at the time, USPS “failed both to quantify the impact of the recession on its finances and to show how its rate request relates to the resulting loss of mail volume.” First-Class mail is becoming a smaller part of the Postal Service’s business because of online communication. The number of individual letters sent each year has fallen by about half in the past decade. DeJoy, appointed during the Trump administration, has pursued sweeping changes during his tenure to try to bolster the agency’s finances. USPS expects to lose $6.3 billion in 2024.
