The Japanese Yen could be the first fiat currency to collapse and trigger a worldwide financial crash due to the country’s unsustainable debt problem, coupled with a lack of effective economic reforms and a dependency on aggressive, and failing, monetary policies. Given Japan’s position as the third-largest economy globally and its extensive international financial linkages, the collapse of the Japanese Yen could have significant contagion effects on other major economies. The inter-connectedness of the global financial system could amplify the impact of a Japanese Yen collapse, potentially triggering a worldwide financial crash.
