ERM is short for exchange rate mechanismERM是「匯率機制」的縮寫。 It is a system它是一種制度，countries use to keep their currencies from jumping too far up or down against each other讓各國的貨幣彼此之間不會大起大落。

The most famous one is the European ERM: governments agreed on a kind of band, so a currency could move a little, but not wildly. The point was steadier trade and, later, a path toward the euro.

The most famous one is the European ERM最有名的就是歐洲匯率機制：governments agreed on a kind of band各國政府約定了一個區間，so a currency could move a little, but not wildly讓一種貨幣可以小幅波動，但不能亂跳。 The point was steadier trade目的是讓貿易更穩定，and, later, a path toward the euro後來也成為通往歐元的一條路。

Though actually, in British news of a certain age, “the ERM” is not a dry textbook idea. It often means 1992, when Britain left the European system in a hurry, on a day still nicknamed Black Wednesday. So the letters can sound like economics in one sentence and like a political bruise in the next.

Though actually不過其實，in British news of a certain age在某個年代的英國新聞裡，"the ERM" is not a dry textbook idea「the ERM」可不是什麼枯燥的教科書概念。 It often means 1992它常常指的是1992年，when Britain left the European system in a hurry英國匆匆退出歐洲那個體系的時候，on a day still nicknamed Black Wednesday那一天至今還被稱為「黑色星期三」。 So the letters can sound like economics in one sentence所以這幾個字母在一句話裡可能聽起來像經濟學，and like a political bruise in the next下一句卻像是政治上的一道傷疤。

This is not a market word, and it is not the euro itself. It belongs to talk about currencies, central banks, and European money history.

This is not a market word這不是市場交易的用語，and it is not the euro itself也不是歐元本身。 It belongs to talk about currencies, central banks, and European money history它屬於談貨幣、央行和歐洲貨幣史時會用的字。
