The treasury is the department or area within a government or organization responsible for managing its money, finances, and financial strategies. It handles tasks like collecting revenue, paying bills, and planning for future financial needs, much like a household manages its budget. For investors, understanding the treasury is important because it influences interest rates, government spending, and overall economic stability.
