Argentine Peso (ARS) to Bolivian Boliviano (BOB) — Parallel Market Cross-Rate
As of July 21, 2026, 1 ARS is worth about 0.006983 BOB, and 1 BOB is worth about 143.213 ARS, using Argentina's and Bolivia's parallel (black market) exchange rates. We derive this cross-rate by bridging both currencies through the US dollar: in Argentina one dollar trades near 1,570 ARS on the street, and in Bolivia one dollar trades near 11 BOB.
For everyday amounts that means roughly 1,000 ARS ≈ 6.983 BOB, and 10,000 ARS ≈ 69.826 BOB, at today's parallel rates.
Bolivian workers and traders in Argentina move pesos and bolivianos across one of South America's busiest land borders.
How the ARS to BOB cross-rate is calculated
There is no large, direct market that quotes ARS against BOB, so the realistic rate is built in two steps through the US dollar — the currency both Argentina and Bolivia actually trade against. First we convert ARS to dollars at Argentina's parallel rate, then dollars to BOB at Bolivia's parallel rate.
Put numerically: 1 ARS ÷ 1,570 (ARS per USD) ≈ $0.000637, then × 11 (BOB per USD) ≈ 0.006983 BOB. Using the street rate on both legs gives a far more realistic figure than multiplying two official rates that may be impossible to obtain.
Why the parallel ARS/BOB rate differs from the official cross
Both of these currencies carry a parallel-market premium of their own. In Argentina, the gap is driven by strict capital controls (the "cepo"), persistent high inflation, distrust of the peso; in Bolivia, by falling gas exports, dwindling reserves, a long-pegged boliviano under strain. Because each official rate can overstate what its currency is really worth, an official ARS/BOB cross can be doubly misleading.
Today Argentina shows a modest premium of about 6.1%, while Bolivia shows a modest premium of about 3.1%. The parallel cross-rate already bakes both of these gaps in, which is why it reflects what traders actually pay.
Argentina and Bolivia: who converts ARS to BOB?
Bolivian workers and traders in Argentina move pesos and bolivianos across one of South America's busiest land borders.
Argentina's "dólar blue" exists because the cepo limits official dollar access — alongside financial rates like the MEP and CCL. Bolivia held the boliviano fixed for over a decade, but shrinking reserves have opened a parallel market for the first time in years.
