How to Read the US Dollar Index

Just like any currency pair, the US Dollar Index (USDX) even has its own chart. Holler at the U.S. Dollar Index:

US Dollar Index (USDX) Chart

First, notice that the index is calculated 24 hours a day, five days a week. Also, the US Dollar Index (USDX) measures the dollar’s general value relative to a base of 100.000. Huh?!?

Okay. For example, the current reading says 86.212. This means that the dollar has fallen 13.79% since the start of the index. (86.212 – 100.000).

If the reading was 120.650, it means the dollar’s value has risen 20.65% since the start of the index. (120.650 – 100.00)

The start of the US Dollar Index is March 1973. This is when the world’s biggest nations met in Washington D.C. and all agreed to allow their currencies to float freely against each. The start of the index is also known as the “base period”.

The U.S. Dollar Index Formula

This is strictly for the grown and geeky. Here is the formula to calculating USDX:

USDX = 50.14348112 × EUR/USD^(-0.576) × USD/JPY^(0.136) × GBP/USD^(-0.119) × USD/CAD^(0.091) × USD/SEK^(0.042) × USD/CHF^(0.036)

Got that? Good! Now you can get a wedgie from the school bully.

We’re kidding!

Queen Cleopiptra usually includes the U.S. dollar index in her Chartology articles so if you’re planning to watch USDX, you should also find out what our resident chartologist has to say.

如何阅读美元指数

       就像任何货币对一样,美元指数也有它自己的图表。让我们呼唤美元指数的图表出来吧:

  

       首先,请注意该指数的是以,一天24小时,每周五天不断被最新计算的。此外,美元指数是使用100.000的基准,来衡量美元的普遍相对价值的。咦?!?

       好吧。举个例子,如果当前的读数为86.212。这意味着,相对于指数的初始值,美元已经贬值了13.79%。(86.212 - 100.000)。

       而如果读数是120.650,这意味着,相对于指数的初始值,美元升值了20.65%。(120.650 - 100.00)

       美元指数是在1973年3月开始启用的。当时世界上的各大国,在美国的首都华盛顿哥伦比亚特区召开会议,并一致同意允许他们国家的货币汇率,可以自由的相对浮动。而美元指数就是由那时开始计算,这时也称为“基础期”。

美元指数的公式

       这个指数,对于它的增长值,有令人讨厌的严格要求。下面是美元指数的计算公式:

            美元指数= 50.14348112 × EUR/USD^(-0.576) × USD/JPY^(0.136) × GBP/USD^(-0.119)
                                    × USD/CAD^(0.091) × USD/SEK^(0.042) × USD/CHF^(0.036)

       明白了吗?很好!现在你可以向学校的恶霸们,拿回被他们扯掉的内裤了。

       我们是开玩笑的啦!
