Sol (currency)

The sol (symbol: $; currency code: FSL), also known as Terran credit and coloquially creds, is a currency which originated in the Terran Federation. It is divided into 100 units. It is now in use in the Terran Federation, Permezi, Somne, Tormen and Perefi Dominions. 
It was introduced in 2076, at the time of the First Commonwealth as the Standard Monetary Unit (SMU). During this period it wasn't the main currency of the nation, but only was used as a reference for other currencies. This would remain until 2139, when it became the official currency of the Terran Federation and was renamed to the sol. It value is fixated on the price of electricity, specifically so that 1MW hour of the time equals one sol. The rate was calculated when the price of electricity had already come crashing down with the arrival of fusion reactors. The value has remained essentially the same throughout all of Federal history. Its value now has only dropped by about 12% compared to its value in 2139. The sol's value is comparable to 2,86 USD in 2018, before the United States and its economy came crashing down.
Members of the Economic Cooperation and Development Association are also obliged to join the Standardisation Group, which allows countries to align their currencies with the sol. The Terran Federation, Permezi Nation, Somne Combine, Tormen Nation and Perefi Republic use the sol as their primary currency. The Menya Union has created the New Menya Credit, with its value being equal to that of the sol. The Dermkha State, Komuggal Republic and Seftet Kingdom are currently creating fixed exchange rates between their currency and the sol.
