A minister of finance (also called financial affairs, the treasury, the economy, or economic affairs) has many different jobs in a government. He or she helps form the government budget, stimulate the economy, and control finances. Finance ministers are often found in state or provincial governments if that country has a form of federalism.
The powers of a finance minister vary between governments. Sometimes the finance minister is the most powerful cabinet post, like in Canada or New Zealand. Other times they are unpopular posts if they must raise taxes or cut spending.
