In 1923 Greenfield moved Reid out of both of his portfolios and made him Provincial Treasurer, where he perpetuated his fiscal conservatism across the government. Early in his tenure, he presented a brief to cabinet recommending that ministers reduce their budgets and that the government create a purchasing department tasked with coordinating spending on supplies. In these proposals he found a close ally in Brownlee, Greenfield's Attorney-General, and when Brownlee succeeded Greenfield as Premier in 1925 he kept Reid as Provincial Treasurer and re-appointed him as Minister of Municipal Affairs. Brownlee and Reid had a history of working closely not only on fiscal issues, but also on agricultural ones: in July 1923, they had travelled together to investigate the creation of a wheat pool in Alberta. This trip included a meeting with cooperative pioneer Aaron Sapiro in San Francisco and a visit to Chicago's commodity market. Both Reid and Brownlee concluded that a pool ought to be proceeded with cautiously, if at all, though this view was overruled when a later visit by Sapiro to Alberta generated sufficient enthusiasm that the government had little choice but to go along with the creation of the Alberta Wheat Pool.
