The boliviano is a freely traded currency and there are no restrictions on the amount of currency that can be brought into or out of the country. However, cash transactions over Bs 10,000 must be declared to the customs authorities.
The Bolivian economy heavily relies on its natural resources like oil and gas, mining, and agriculture. As such, fluctuations in the prices of these commodities can have a significant impact on the Bolivian economy, and therefore, the boliviano.
There is also a high inflation rate in the country which contributes to the volatility of the Boliviano.
