What does reopening USD accounts mean for the boliviano?
It likely signals increased demand for dollars as savers legally convert from bolivianos, putting depreciatory pressure on the currency. The parallel rate may converge to the official rate, suggesting an upward adjustment in USD/BOB.
How long could the impact last?
Short-term pressure is expected as markets adjust, but sustained depreciation depends on the central bank's foreign reserve levels and whether confidence in the boliviano is restored or further eroded.
Is this a move toward full dollarization?
It is not full dollarization, but an expansion of dollar usage within the financial system. If boliviano confidence declines further, it could accelerate de facto dollarization, but official adoption of the dollar as legal tender would require legislative change.
