Which system was established by the National Monetary Commission in 1908 to investigate the country’s monetary policy?

The Federal Reserve was established as a result of the findings and recommendations of the National Monetary Commission created in response to financial panics and economic instability in the United States during the early 20th century. The Commission aimed to investigate and improve the country's monetary policy, ultimately leading to the creation of a central banking system that could provide stability to the financial system.

The Federal Reserve was officially established in 1913, and it serves multiple functions, including regulating the money supply, conducting monetary policy, supervising and regulating banks, and providing financial services. It was designed to address the shortcomings of previous monetary systems, particularly in managing financial crises and ensuring a more stable economic environment.

The other options listed do not represent the foundational outcomes of the National Monetary Commission's work. The Central Bank System is a general term and does not refer specifically to the institution created in 1913. The Monetary Relations Committee and Financial Oversight Authority do not correspond to entities established by the Commission and are not relevant to the historical context of the Federal Reserve's creation.
