【案例分析題】

以下是近期《時代周刊》中介紹新上任的一位IMF官員對IMF未來如何發(fā)揮其職能的個人看法的材料：
WhatO’Neill has said repeatedly is that theI MF should stop playing fireman，rushing to help after a country’s finances have burst into flames，and becomea“firemarshal”（消防署署長）instead.This means interfering early，advising countries exactly what is wrong and what reforms are needed，tracking results and then issuing public warning when countries are heading for disaster.”if a country willfully（固執(zhí)地） follows bad policies that it’s been talked to about，”saysO’Neill，”we can be more relaxed in saying to them：’weare not going to be there when chickens come to roost（習語，指惡行的自作自受）.’”
請根據(jù)以上材料，回答下列問題：

你覺得一國出現(xiàn)貨幣金融危機會完全是由于“壞政策”造成的嗎？還有哪些因素也可能現(xiàn)在的貨幣金融危機爆發(fā)負責任。
