solution

• the Grand coalition was led by Gustav Stresseman and lasted 103 days, it was the first party to include parties from the moderate right DVP, the center party, socialists, and DDP.
• Stresseman stopped the german government from printing money, stopping quantative easing and ensuring no more marks were entering circulation (caps the money supply), meaning the mark would not become less valuable
• Stresseman scrapped the original reichsmark and introduced the rentenmark as a temporary currency, and allowed people to trade in old marks for the new currency, allowing germany to reset economically
• The rentenmark was backed by a foreign stable currency as a result of american loans that supported the german economy like those as a result of the Dawes Plan, meaning germany had achieved economic stability as a result of being backed by the US dollar
