Quick answer
The Central Reserve Bank of Peru targets inflation of 1% to 3% and sets a reference rate each month, but what distinguishes it is how actively it manages the currency. It intervenes to reduce volatility in the sol and holds very large reserves for an economy of Peru's size: about USD 97.8 billion on average in September 2026, up from about USD 61.7 billion in January 2019. The 10-year sovereign yield in soles averaged 6.48% in September 2026.

BCRP snapshot
The figures below are official statistics as stored on the Peru data page. Each carries its own date, because measures taken from different points in the cycle give a misleading picture.
| Measure | Latest | As of |
|---|---|---|
| 10-year sovereign yield | 6.48% | September 2026, monthly average |
| Net international reserves | USD 97.8 bn | September 2026, monthly average |
| Inflation target | 1% to 3% | 2% midpoint |
| USD/PEN | 3.4205 | 25 September 2026 |
Mandate and instruments
Peru's constitution makes the central bank autonomous and gives it a single purpose: preserving monetary stability. The Bank pursues that through inflation targeting, with a target of 2% and a tolerance range of one percentage point either side, so 1% to 3%. That is one of the lowest targets in Latin America.
The Board sets a reference rate for the interbank market at a monthly monetary programme meeting. Alongside it, the Bank uses reserve requirements, with separate and typically higher ratios on US dollar deposits, because the Peruvian financial system remains partly dollarised. Reserve requirements on dollar liabilities limit the build-up of currency mismatches.
The third element is foreign exchange intervention. The Bank buys and sells dollars in the spot market and uses currency swaps to dampen sharp moves in the sol. The stated aim is to reduce volatility, not to set a level, and the size of the reserve stock is what makes that credible.
The sovereign yield as a measure of risk
The 10-year sovereign yield in soles gives a market reading that combines expected policy rates with Peru's risk premium. On a monthly average basis it fell to 3.63% in December 2020, climbed to 8.64% in October 2022 as global rates rose and domestic political uncertainty increased, and has been lower since, though not in a straight line: 6.62% in December 2024, 5.83% in December 2025 and 6.48% in September 2026.
The range is wide for a country with low and stable inflation, which is the point: movements in the Peruvian long end have been driven as much by global yields and political risk as by the central bank.
10-year sovereign yield
Peruvian government bond yield in soles, 10-year maturity, percent, monthly average.
Takeaway: The 10-year yield moved between 3.63% and 8.64% over the period and averaged 6.48% in September 2026.
Reserves: the foundation of the framework
Net international reserves are the resource behind intervention. They averaged about USD 61.7 billion in January 2019 and reached a monthly average of almost USD 100 billion in May 2026, before easing to about USD 97.8 billion in September.
A reserve stock of that size relative to the economy lets the Bank lean against disorderly moves in either direction without changing the reference rate, which is why Peruvian interest rates can be set for inflation while the exchange rate is managed separately.
Net international reserves
Central Reserve Bank of Peru net international reserves, USD billion, monthly average.
Takeaway: Reserves rose from about USD 62 billion in early 2019 to almost USD 100 billion in May 2026.
How BCRP policy reaches the sol
The sol is a managed float with frequent official presence. Intervention smooths the path rather than reversing the trend, so the currency still responds to fundamentals: copper and gold prices, which dominate Peru's exports, the interest-rate differential against the US dollar, and domestic political risk.
USD/PEN was about 3.72 at the start of October 2024, peaked near 3.80 in November 2024, and was about 3.42 in late September 2026. The sol's appreciation over that period came alongside rising reserves, which indicates the Bank was buying dollars into strength rather than resisting it.
The USD/PEN dashboard puts the exchange rate beside the rate differential and the release calendar for both economies.
