For almost fifteen years, Bolivia's official exchange rate did not move: Bs 6.96 per US dollar (selling rate), fixed since November 2011. That stability broke down in practice when dollars became scarce in the banking system and a parallel market emerged, largely channelled through USDT on peer-to-peer (P2P) platforms. In June 2026 the country formally changed regime: on 29 June a flexible exchange-rate scheme came into force, with an initial official rate of Bs 9.73. This article explains how the new Official Exchange Rate (TCO, for its Spanish initials) works and how to read it without getting confused.

What changed in June 2026

The change rested on a resolution from the Ministry of Economy and a board resolution from the Central Bank of Bolivia (BCB) approving new rules for foreign-exchange operations. According to information released by the BCB and the Bolivian press, the main points are:

  • The fixed rates of Bs 6.86 (buying) and Bs 6.96 (selling) were abandoned, along with other reference rates that coexisted with them.
  • The BCB publishes a single official exchange rate, updated every business day.
  • The value is no longer administered as a fixed number; it reflects operations in the market.
  • The BCB said it does not intervene routinely and would act only against disorderly moves or market "overreactions".

How the TCO is calculated

The TCO is a weighted average of the dollar purchases that banks make from their customers. "Weighted" means that larger transactions count more in the average than small ones. The figure is calculated from one day's operations and published to apply on the following day.

Three practical ideas follow from this:

  1. The TCO arrives with a one-day lag. It reflects what happened yesterday in the banking system, not the price at this minute.
  2. It is not the price you will get. Each bank or exchange house sets its own buying and selling prices around that reference. In the first months of the new regime, differences of roughly 1–2% between institutions were observed.
  3. It can go up or down. Unlike the old regime, a higher TCO today does not guarantee that it will keep rising tomorrow.

How it has moved since the reform

The official rate started at Bs 9.73 on 29 June and rose over the following weeks: around 21 August it was close to Bs 11.5, and in early October it stood near Bs 12 (the BCB reported Bs 11.97 for 7 October). For the Bolivian economy this is a large depreciation of the boliviano compared with the old 6.96 peg, although much of the adjustment had already happened in the parallel market, where the digital dollar traded above Bs 15 at times in 2025.

According to the BCB, the new regime allowed it to buy foreign currency from the financial system and add more than 400 million dollars to its reserves between July and August. The stated goal is to stabilise the supply of dollars and help bring down inflation, which exceeded 20% in 2025.

The TCO versus the P2P dollar

An interesting consequence of the flexible regime is that the gap between the official rate and the price of USDT on P2P platforms narrowed sharply. Before the reform, that difference exceeded 30%. On the live data ticker on our home page, in early October 2026 USDT/Bs on P2P traded very close to the TCO, with a difference of less than 1%. A small gap means the official and informal markets are "speaking the same language". If it widens again, it is usually a sign of stress: a shortage of dollars at banks, expectations of depreciation or new restrictions.

In another article in this series we explain step by step how to calculate the gap and what its limitations are.

Common mistakes when reading the exchange rate

  • Looking at a single day. Under a flexible regime, daily jumps can reverse; it is better to look at the trend over several weeks.
  • Confusing the reference with the final price. Your bank, exchange house or P2P advertiser will add its own margin.
  • Ignoring costs. Fees, daily limits and settlement times change the effective price you obtain.
  • Assuming flexible means free-floating. The BCB can step in against abrupt moves; a flexible regime does not rule out intervention.

A worked example

Suppose a small importer in Santa Cruz needs 5,000 dollars to pay a supplier. The TCO published for today is Bs 11.97. Her bank quotes Bs 12.15 to sell dollars, charges a transfer fee and can process the payment in two days. On a P2P platform, the average of several sellers with bank transfer is Bs 12.05, but she would then need to send USDT to the supplier or convert it. The decision is not just "which number is lower": it depends on fees, timing, limits and whether the supplier accepts stablecoins.

What to watch

  1. The TCO published daily by the BCB and its weekly trend.
  2. The gap with USDT on P2P platforms.
  3. Inflation data from the National Statistics Institute (INE): falling inflation supports the boliviano.
  4. International reserves reported by the BCB.
  5. Official announcements about changes to foreign-exchange rules.

Bottom line

The TCO is no longer a fixed number you can memorise: it is an average of what happened yesterday in the banking system. For real decisions — saving, paying for imports or receiving dollars — compare the TCO, your bank's actual price and the P2P market, add up the costs of each route and avoid reacting to a single day's move.
