Why 155 Nations Still Choose to Lock Their Currency Values
Washington, Tuesday, 15 September 2026.
An updated IMF report reveals that 155 countries continue to peg their exchange rates to foreign currencies in 2026. While pegs offer stability, they surrender monetary independence—a risk underscored when Bolivia abandoned its U.S. dollar link in June 2026, causing a sudden 29.3% devaluation.
Global Reliance on Fixed Rates
An updated International Monetary Fund report reveals that 155 nations continue to maintain fixed exchange rates in 2026, anchoring their currencies to major external benchmarks or currency baskets [1]. The data, drawn from the IMF’s Annual Report on Exchange Arrangements and Exchange Restrictions (AREAER) 2023 and updated through September 14, 2026, highlights a persistent global reliance on hard pegs, soft parities, and crawl-like arrangements [1]. This classification is based on de facto exchange-rate regimes derived from actual spot rate performance over the previous six months, rather than relying solely on official central bank statements [1]. The widespread use of these arrangements underscores ongoing monetary policy fragmentation and significant foreign exchange risks for international business operations and capital flows [1].
Major Currency Anchors
The United States dollar and the euro remain the primary anchors for these fixed regimes, with specific jurisdictions maintaining rigid parity for decades [1]. USD-anchored economies include Saudi Arabia, which has maintained a rate of 3.75 SAR/USD since 1986, and the UAE, while the CFA franc zones continue to peg at 655.957 XOF/XAF per euro [1][2]. Significant structural changes occurred in early 2026, as Bulgaria exited its lev board on January 1, 2026, upon joining the euro area with an irrevocable conversion rate of 1 EUR = 1.95583 BGN [1][2]. Additionally, Curaçao and Sint Maarten replaced the Netherlands Antillean guilder with the Caribbean guilder (XCG) on March 31, 2025, maintaining a 1.79 USD peg [1].
The Cost of Stability
Despite the perceived stability, fixed exchange rates surrender monetary independence, a risk starkly illustrated when Bolivia abandoned its official 6.96 BOB/USD peg between June 26 and June 29, 2026 [1][2]. Following the abandonment of the peg, the daily weighted bank trade rate reached approximately 9.83 BOB by August 2026, reflecting a substantial devaluation [1][2]. The magnitude of this shift is calculated as 41.236, resulting in a devaluation of approximately 29.3% [1][2]. This event underscores the ‘impossible trinity’ dictate, where countries cannot simultaneously maintain a fixed exchange rate, an independent monetary policy, and open capital markets without importing the anchor’s interest-rate path [1].
Market Volatility and Outlook
Five-year annualized volatility from September 2021 to September 2026 shows clusters near zero for stable pegs like Bermuda and Brunei, whereas stressed pegs exhibit extreme fluctuations [1]. Lebanon, identified as a stressed peg with an official rate of 89,500 LBP/USD following the collapse of its previous 1,507 peg, printed 210% realized volatility during this period [1]. Other stressed regimes identified by the IMF include Iraq, with an approximate 18% cash premium over the bank sell rate, and the Maldives, where the rufiyaa traded at the weak edge of a ±20% band [1]. As of September 15, 2026, the data indicates that while many nations retain pegs, the pressure on these arrangements remains a critical focal point for global economic stability [1][2].
