What does the Treasury, also known as the Exchequer, oversee?

The Treasury, also known as the Exchequer, is primarily responsible for managing the country's public finances, which include government revenue and expenditure. It oversees the formulation and implementation of economic policies that affect the overall financial health of the nation. This includes budgeting, taxation, and the allocation of funds to various government departments and services. The Treasury plays a crucial role in ensuring fiscal stability, managing public sector spending, and influencing economic growth through various financial mechanisms.

While international trade, environmental regulation, and education funding are significant areas of government policy, they fall more specifically under the purview of other departments or agencies. For instance, international trade policies would typically be managed by a trade department, environmental regulation would be overseen by an environmental agency, and education funding would be handled by the education department. The Treasury's broader focus on public finance and economic strategies is what sets it apart, making it the correct answer to the question.
