In the meantime, the country must be careful about joining the exchange rate mechanism (ERM II) – the narrow band within which applicant currencies must operate for at least two years prior to adopting the euro. Doing so could cause the złoty to strengthen, as it did to the Slovak koruna, and wipe out Poland’s competitive advantage.
尽管波兰公司努力地建立海外品牌，但这可能需要几十年时间。与此同时，波兰在加入汇率机制（ERM II，在采用欧元之前，申请国货币汇率的波动范围必须限制在一个狭窄范围内，时间不短于两年）时要慎之又慎。这样做可能导致兹罗提升值（就像斯洛伐克克朗一样），导致波兰失去竞争优势。
