About bank rates.

Probably because you will have to invest in Dominican Pesos.

Leonel has tried his hardest to keep the Peso pegged to the USD and has done quite well so far. However, people are realising that this is artificial and this steady exchange rate is now showing signs of weakening.

I wouldn't lock my money into Pesos just yet, I think the Peso is in for a rocky ride ahead for a while.
