# Almost All TSP Funds Down Year-to-Date after March Plunge; Brief Reprieve

> All three TSP stock funds fell in March 2026, with the C Fund down 4.98%, the S Fund down 4.58% and the I Fund down 9.35%. The C and S funds are now negative year-to-date, while the I Fund remains up 1.84%. Losses were attributed to the war in Iran, with a late-March rally tied to hopes of a coalition to reopen the Strait of Hormuz.
