Can you show there is no corresponding increase in production?
If the banks are flush with cash on which they are paying interest, what are they supposed to do with it besides find methods of lending?
That is what a bank does.
It's the opposite from when Hippo was in power. Back then interest rates on loans where to the roof, and business after business had to stop project after project because they couldn't afford money. Even Cap Cana came to a halt. What's happening now is that individuals with money are confident enough in the future of the Dominican economy to put a larger sum of their money in the domestic banks, as oppose to sending it to bank accounts overseas. Like you said before, debt borrowing if how business largely gets done. In fact, I'm sure Cap Cana itself is in debt to its eyeball -- that's how if had managed to fastrack its contruction.
That money is going to the production sector: project after project that were stopped during the Hippo year are now going fast, Cap Cana would be an example.
If anything the Central Bank main policies are serving a countervailing effect to this. i.e. it seems everyone complaints about how if seems to overvalue the Peso through an apperent pegging to the Dollar. In so far as general inflation is concerned, the Abezu at the Central Bank has done a rather well (amazingly well when conpared to the previous administration) in keeping is relatively low and stable, particularly given the way crude oil prices and its derivatives have been spiking during his term there.
But something else that may add to it would be the policy of the Dominican bank athorities of restricting nepotistic loans by the domestic bank, which that to some extent forced than to actually consentrate more on loaning/investing to those more productive. i.e. BHD to Roco Ki ..Banco Leon to Cap Cana, which I'm sure is of to debt higher than it neck.
About the only main sector of the productive economy that's not seen a boom is FTZs, that in itself is also amazing.

Generally around, a good development.
