I am only aware of it's affects on Germany these are:
Prior to the Great Depression and the Wall street crash(in 1929), Germany (during the Steseman years) was recovering from WWI and the harsh terms of the Treaty of Versailles. They needed money to pay of 6,600 million in reparations to the allies, but didn't have enough. However when Gustav Streseman came to power he organised the Dawes and Young Plans (named after two wealthy American bankers) which was in scheme in which the USA leant money to Germany in order for them to pay off the reparations. However during the Great Depression, America was in financial turmoil and desperately needed the money leant to Germany back. This left Germany bankrupt and back at square one. Subsequently after Streseman died in 1929 of a heart attack due to all the pressure of a failing nation.
I hope this helped a bit.
