求助prep题中一句话的翻译

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!

若不是由于政府高额的赤字，该预期不会对美元产生负面影响，因此赤字需要减少以避免进一步的货币贬值。
