After a rocky end to 2024, all funds in the federal government’s 401(k)-style retirement savings program finished January in the black.

Each of the portfolios in the federal government’s 401(k)-style retirement savings program bounced back from a difficult December last month.

The small- and mid-size businesses of the Thrift Savings Plan’s S Fund saw the best performance, gaining 4.99% in value in January. And the I Fund, which is made up of international investments, grew 3.68% last month.

The common stocks of the C Fund ended January 2.78% in the black, while the fixed income (F) fund grew 0.51%. And the G Fund, which increases at a statutorily mandated rate, gained 0.39% last month.

Likewise, each of the TSP’s lifecycle (L) funds, which shift toward more conservative investments as participants get closer to retirement, grew in January. The L Income Fund, which is designed for people who have already begun making withdrawals, gained 1.20%; L 2025, 1.28%; L 2030, 2.21%; L 2035, 2.38%: L 2040, 2.56%; L 2045, 2.71%; L 2050, 2.86%; L 2055, 3.36%; L 2060, 3.36%; L 2065, 3.36%; and L 2070, 3.36%.
