Just reinforcing that you can’t read, huh? Literally in the same link already provided:

An associated problem starts pretty quickly with the fiscal health of Texas. They will have to print their own money and swap out US dollars for their own money (Republic of Texas Dollars or Pesos or whatever they’d like to call them)… let’s call them TexBux (thanks Nicholi Valentin). If they don’t get their financial house in order from the get-go, that will see high inflation, where TexBux quickly fall against the USD and the MNX.

Maybe they just peg the TexBuck to the US Dollar? That’s possible: about 66 countries peg their currencies to the US Dollar. However, this is kind of magic trick conducted by their central bank — you can’t just make the claim that a TexBuck is the same as a Dollar. The central bank in such a country will buy up large numbers of US Treasury Notes. If TexBux fall next to the US Dollar, they sell Treasuries and buy TexBux, which both lowers the value of the US Dollar just a bit, and raises the value of the TexBuck.

Of course, this presumes that The Republic of Texas magically turns into a real country. Given the typical Texas leadership, that seems pretty unlikely. Yeah, they’d need some kind of central bank and mint to print money, but would they really have a monetary policy capable of pinning the TexBuck to the Dollar? Would that even be possible in the Texas economy — this is not The Bahamas we’re talking about here. There’s an awfully good chance that US imports get expensive, real fast.
