我做到一题prep题,有句话不怎么理解.The recent decline in the value of the dollar was triggered by a prediction of slower economic growth in the coming year.But that prediction would not have adversely affected the dollar had it not been for the government's huge budge deficit,which must therefore be decreased to prevent future currency declines.

请问高亮的那句话怎么翻译啊?谢谢!
