Sherman was elevated to the Senate in 1861. As a senator, he was a leader in financial matters, helping to redesign the United States' monetary system to meet the needs of a nation torn apart by civil war. After the war, he worked to produce legislation that would restore the nation's credit abroad and produce a stable, gold-backed currency at home.

Serving as Secretary of the Treasury in the administration of Rutherford B. Hayes, Sherman continued his efforts for financial stability and solvency, overseeing an end to wartime inflationary measures and a return to gold-backed money.  Chase resigned his Senate seat on March 7, and after two weeks of indecisive balloting, the Ohio Legislature elected Sherman to the vacant seat. He took his seat on March 23, 1861, as the Senate had been called into special session to deal with the secession crisis.
