Bolivian Boliviano (BOB) to Argentine Peso (ARS) — Parallel Market Cross-Rate
As of June 6, 2026, 1 BOB is worth about 150.286 ARS, and 1 ARS is worth about 0.006654 BOB, using Bolivia's and Argentina's parallel (black market) exchange rates. We derive this cross-rate by bridging both currencies through the US dollar: in Bolivia one dollar trades near 10 BOB on the street, and in Argentina one dollar trades near 1,495 ARS.
For everyday amounts that means roughly 1,000 BOB ≈ 150,286 ARS, and 10,000 BOB ≈ 1,502,859 ARS, 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 BOB to ARS cross-rate is calculated
There is no large, direct market that quotes BOB against ARS, so the realistic rate is built in two steps through the US dollar — the currency both Bolivia and Argentina actually trade against. First we convert BOB to dollars at Bolivia's parallel rate, then dollars to ARS at Argentina's parallel rate.
Put numerically: 1 BOB ÷ 10 (BOB per USD) ≈ $0.100503, then × 1,495 (ARS per USD) ≈ 150.286 ARS. 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 BOB/ARS rate differs from the official cross
Both of these currencies carry a parallel-market premium of their own. In Bolivia, the gap is driven by falling gas exports, dwindling reserves, a long-pegged boliviano under strain; in Argentina, by strict capital controls (the "cepo"), persistent high inflation, distrust of the peso. Because each official rate can overstate what its currency is really worth, an official BOB/ARS cross can be doubly misleading.
Today Bolivia shows a steep premium of about 43.8%, while Argentina shows a modest premium of about 4.2%. The parallel cross-rate already bakes both of these gaps in, which is why it reflects what traders actually pay.
Bolivia and Argentina: who converts BOB to ARS?
Bolivian workers and traders in Argentina move pesos and bolivianos across one of South America's busiest land borders.
Bolivia held the boliviano fixed for over a decade, but shrinking reserves have opened a parallel market for the first time in years. Argentina's "dólar blue" exists because the cepo limits official dollar access — alongside financial rates like the MEP and CCL.
