"Citizens will access to this so-called third segment as well, experiencing a 232% increase against the rate of 1 USD = 123.60 Cuban pesos, which now will be available to government-picked entities only as the second segment."

I do not understand this. I think the value of dollars will rise against the CUP (from 123 to 410), but the second and third segments of the financial exchange markets remain unclear to me, in terms of who has access to which. However, your subsequent discussion of increased availability of dollars to the public sounds like a very positive development, as presently - and despite their horrific inflation - dollars represent one of the strongest currencies in global markets (which is an indictment of all the rest of them, as the price of silver and gold in dollars is rapidly increasing, which indicates not that PM's are becoming more valuable, but that dollars are rapidly declining in value relative to commodities) and this may help Cubans to resist inflation and retain more of the value of their earnings.

Thanks!
