Aridor's first ministerial appointment was the Minister of Communications, in 1981. In this position, Aridor immediately restored television color broadcasting. In the 1970s, color bursts (the signals encoding colors) were actively removed from IBA transmissions, in an attempt to discourage the population from buying new television sets. Aridor's action led to an increase of his popularity, and boosted his political career.
Two weeks later he was appointed the Minister of Finance, and again took a populist approach, lowering taxes on automobiles and household appliances. As such, his days as finance minister were called the "Merry Aridor Days". The lowering of inflation in Israel during his first years in office is attributed in part to this policy, leading to an increase in government's income from taxes. In subsequent years however, the inflation rose sharply (from 102% in 1981 to 191% in 1983), and as a countermeasure Aridor proposed to peg the Israeli shekel to the US dollar at a fixed exchange rate. He resigned his position on 15 October 1983 due to widespread criticism of his "dollarization plan".

Attorney Yoram Aridor, who served as Minister of Finance from 1981, is remembered for the important reforms he initiated, but mostly for approving the first color broadcast, which led to a dramatic increase in the number of TV sets purchased.
