It is actually the inflation’s side effect.
The money worth less than the paper they paint it on. So, they use a higher number.
You can see how it begins (again) in Turkish Lira. In 2007, Turkey removed 6 zeroes from the money (ie 10 million TLs become 10 TLs). The $/TL was something like 1.20.
Now, $/TL is 8.65. TL loses it’s worth.
To somewhat counter that, countries issue higher bills. So that the minimum wages can keep up against the inflation and people can afford basic stuff like electricity bills and such.
