The three possible future scenarios for Wales all warned of economic stress in one form or another. Only independence, it said, might free the country to pursue financial gain. In the short to medium term, however, this would seriously hurt the country.
"We would work through this period using the economic levers at our disposal," Mr ap Iorwerth said. "For me, the best way to do this would be to have our own currency. We wouldn't have to, we could choose to keep the pound, but there are all sorts of options to take to mitigate those challenges of becoming an independent country."
Wales hasn't had a native currency for hundreds of years. Its monetary system was only unified with the creation of the Welsh Pound in the 16th century, and even that was based on its neighbour's money. It was replaced by the English Pound in 1707 and was later swapped for the Pound Sterling in 1801.
Unlike Scotland, Wales has neither a central bank nor treasury, both vital cogs in the creation and maintenance of a national currency.
Mr ap Iorwerth said: "If we have our own treasury in the future, we'd have the option of having our own bank [which would then] give us the option of making decisions about currency."
Remember Wales that England's currency was either actual silver or based on the value of silver until 1914 - after 1914 inflation took off and sterling has halved in value (Purchasing power) every ten years since then. We need paper money which are promissory notes whereby the promise is broken by law to stop people asking for their weight in pounds of silver (Banking Restriction Act 1796). So paper is dangerous and all electronic money even more so as that can be shaved in value or simply vanish. People need to be able to hold silver tax free, no VAT, no CGT or income tax on silver nominal or actual gains in value against government currency. That way people can protect themselves and still trade beyond the reach of electronic control systems and technocracy, in actual silver metal.
