https://www.federalreserveeducation.org/about-the-fed/historyAfter the panic of 1907 and growing a concern and desire for banking reform, "The Aldrich-Vreeland Act of 1908, passed as an immediate response to the panic of 1907, provided for emergency currency issue during crises. It also established the national Monetary Commission to search for a long-term solution to the nation’s banking and financial problems."
In December 23, 1913 "President Woodrow Wilson signed the Federal Reserve Act into law... a decentralized central bank that balanced the competing interests of private banks and populist sentiment."
During the WWI, the Fed's "greater impact in the United States came from the Reserve Banks’ ability to discount bankers acceptances. Through this mechanism, the United States aided the flow of trade goods to Europe, indirectly helping to finance the war"
The Fed would continue to undergo more changes including: the end of reliance on gold to control credit, the beginning of open market operations, increased relations with foreign central banks, passing of the Glass-Steagall Act and FDIC as a response to the Great Depression, all the way up to the 2006 recession into our current modernized and globalized financial stage.
