The federal government’s 401(k)-style retirement savings program was not immune to the economic headwinds brought on by President Trump’s war with Iran.
Nearly all the portfolios within the federal government’s 401(k)-style retirement savings program lost ground last month, as the global economy buckles from disruptions resulting from President Trump’s bombing campaign in Iran.
The Thrift Savings Plan’s G Fund, which is made up of government securities, was the sole offering to finish March in the black, increasing by its statutorily mandated rate of 0.34%. So far in 2026, the G Fund has gained 1.04%.
The common stocks of the C Fund lost 4.98% last month, bringing its performance since January to 4.34% in the red. And the small- and mid-size businesses of the S Fund fell 4.58%, wiping out its gains this year. So far in 2026, the S Fund has lost 1.22% in value.
