seems your trying too hard to justify all the variations of "dollar" value
Its not hard at all. Different places have different costs of living even within the same country. Nearly every country that's big enough experiences this.
you win no awards defending the dollar.
I'm not defending anything. I'm simply telling you. Its the least volatile of all currencies because it is the most widely traded. This isn't an opinion.
https://admiralmarkets.com/education/articles/forex-basics/what-are-the-best-currency-pairs-to-tradeNot surprisingly, the most dominant and strongest currency, as well as the most widely traded, is the US dollar. The reason for this is simply the sheer size of the US economy, which is the world's largest. The US dollar is the preferred reference in most currency exchange transactions worldwide. It is the dominant reserve currency of the world.
and if you think the pound is to blame for why dollars value against it changes.
then you have to explain the changes of the other 100+ countries
oh wait. its all the other countries faults. i get it you love and adore the dollar and you want to wrap the dollar in cotton wool and protect it.
good luck
OK look, there's no point in trying to help you understand the point I'm making because you seem intent on belittling me. It has nothing to do with "fault", it has to do with the fact that the dollar-based currency pairings are the most liquid on the planet.
https://www.investopedia.com/articles/forex/11/popular-currencies-and-why-theyre-traded.aspFirst and foremost is the U.S. dollar, which is easily the most traded currency on the planet. The USD can be found in a pair with all the other major currencies and often acts as the intermediary in triangular currency transactions. This is all because the USD acts as the unofficial global reserve currency, held by nearly every central bank and institutional investment entity in the world.
In addition, due to the U.S. dollar's global acceptance, it is used by some countries as an official currency, in lieu of a local currency, a practice known as dollarization. The U.S. dollar also may be widely accepted in other nations, acting as an informal alternative form of payment, while those nations maintain their official local currency.
The dollar is an important factor, too, in the foreign exchange rate market for other currencies, where it may act as a benchmark or target rate for countries that choose to fix or peg their currencies to the USD's value. China, for instance, has long had its currency, the yuan or renminbi, pegged to the dollar, much to the disagreement of many economists and central bankers. Quite often countries will fix their exchange rates to the USD to stabilize their exchange rate, rather than allowing the free (forex) markets to fluctuate its relative value.
