Germany faced hyperinflation after World War I due to printing money to fund the war and pay reparations, which led to economic hardship, uncertainty in the new democratic government, and questions about peace. The Dawes Plan in 1924 provided a US loan to stabilize Germany's currency and helped its economy recover by 1929, improving conditions for maintaining peace agreements like the Locarno Treaty and Kellogg-Briand Pact that Germany signed.
