[1] Camacho took a prominent part in all financial debates and committees, was offered a seat in the Mon cabinet of 1864, and was appointed under-secretary of state finances in 1866 under Cánovas and Leopoldo O'Donnell, Duke of Tetuan.
After the revolution of 1868 he declined the post of minister of finance offered by Marshal Serrano, but served in that capacity in 1872 and 1874 in Sagasta's cabinets.
[1] When the restoration took place, Camacho sat in the Cortes among the dynastic Liberals with Sagasta as leader, and became finance minister in 1881 at a critical moment when Spain had to convert, reduce, and consolidate its treasury and other debts with a view to resuming payment of coupons.
[1] A few years later Sagasta again made him finance minister under the regency of Queen Christina, but had to sacrifice him when public opinion very clearly pronounced against his too radical financial reforms and his severity in collection of taxes.
He then seceded from the Liberals, and during the last years of his life he affected to vote with the Conservatives, who made him Governor of the Bank of Spain.
