Two numbers came out of the Banco Central del Paraguay (BCP) on 25 August 2026, and the distance between them is the whole story. Its Superintendencia de Bancos fixed the September ceiling on lending rates at 27.39% a year in guaraníes and 11.31% in dollars, the level above which interest becomes usurious. The same day, the bank's Monetary Policy Committee left the reference rate at 5.50%, unchanged and unanimous, with annual inflation at 1.6%.
Paraguay is a cheap country to live in and an expensive one to borrow in. Those two facts sit in the same set of monthly figures, and anyone planning a property purchase or a local loan should read the second one before assuming the first carries over.
What the September Ceiling Covers
The usury limit is not a rate any borrower is quoted. It is the line past which a lender is breaking the law, published every month by the Superintendencia de Bancos under Ley 2339/2003 and applying to loans written in that month.
September's limits sit marginally above August's, continuing a slow upward drift through the year:
| Month | Guaraníes | Dollars |
|---|---|---|
| July 2026 | 27.04% | 11.24% |
| August 2026 | 27.26% | 11.25% |
| September 2026 | 27.39% | 11.31% |
The arithmetic behind the number explains why it moves so little. The Superintendencia takes the average effective annual rate that banks and finance companies charge on consumer credit, then adds a margin of 30%. The ceiling therefore follows the consumer-credit market rather than leading it.
Credit cards are capped separately and considerably lower. For August the card limit was 19.81% in guaraníes and 10.94% in foreign currency, against 19.88% and 10.73% in July.
What Paraguayan Banks Actually Charge
The averages reported alongside the September ceiling are a better guide to real borrowing costs, and they vary enormously by purpose:
| Credit type, in guaraníes | Average rate |
|---|---|
| Consumer | 22.91% |
| Commercial | 12.74% |
| Development | 10.94% |
| Housing | 9.59% |
Across all categories the system average is roughly 16% in guaraníes and 7.62% in dollars. Note where the money is dear: an unsecured consumer loan costs more than twice what a mortgage costs, because the collateral does the work of holding the rate down.
Set that consumer figure of 22.91% against the 5.50% policy rate and the spread runs past seventeen points. It reflects a shallow credit market with high administrative costs per loan, not a temporary condition anyone expects to close soon.
Why the Policy Rate Did Not Move
The Monetary Policy Committee was unanimous in leaving the rate at 5.50%. Consumer prices fell 0.1% in July, and annual inflation of 1.6% sits well under the 3.5% target, with core inflation at 1.3%.
The committee is looking past those readings rather than at them. Survey expectations put inflation at 3.5% over the next twelve months and 3.3% at the close of this year, which is to say back at target, so the case for cutting into unusually soft numbers is weaker than it appears.
Activity gave it no reason to ease either. The IMAEP monthly activity index rose 5.6% year on year in June and the business figures estimator gained 4.1%, keeping the 2026 growth forecast of 4.5% intact. Services, agriculture, electricity and water, vehicle sales, pharmaceuticals and construction materials all contributed.
The next decision is scheduled for 21 September 2026. Energy prices and the international rate environment were named as the risks worth watching between now and then.
What This Means If You Are Moving Money Here
Start with the mismatch. A monthly budget in Paraguay is modest by any developed-country standard, as our cost of living guide sets out, but financing is priced for a small market with a short credit history, and the two do not converge just because you have moved.
For a property purchase the consequence is arithmetic. At an average housing rate of 9.59% in guaraníes, borrowing locally costs meaningfully more than a mortgage in most of the countries our readers come from, which is one reason so many foreign buyers purchase outright rather than finance.
Currency adds a second layer that the headline rate hides. A guaraní loan serviced from dollar income has grown more expensive this year, because the guaraní has appreciated 23% against the dollar and every installment now converts at a worse rate than the one you modelled. A dollar loan avoids that and averages less, around 7.62%, but it is not the exposure a guaraní earner wants.
One caution applies to all of these figures. They describe what the system charges established borrowers with local records behind them. A file opened in your first year here is not the file those averages are built from, so treat them as the shape of the market rather than as a quote. How the relationship starts is covered in our guide to opening a bank account.
None of it touches your tax position. Rates govern the price of credit, while the territorial system governs what Paraguay taxes, and genuinely foreign-source income stays outside the local net regardless of what the BCP does with the policy rate.
US citizens and green-card holders: interest rates have no bearing on your filing position. The United States taxes worldwide income on the basis of citizenship, so Paraguayan residency does not end the obligation, whatever the local cost of money.
Frequently Asked Questions About Paraguayan Interest Rates
What is the maximum legal interest rate in Paraguay?
For September 2026 the ceiling is 27.39% a year on loans in guaraníes and 11.31% on loans in dollars, published by the BCP's Superintendencia de Bancos under Ley 2339/2003. Credit cards carry their own lower limit, which stood at 19.81% in guaraníes for August. Anything charged above the applicable ceiling counts as usury.
Why is the ceiling so much higher than the 5.5% policy rate?
Because the two measure different things. The policy rate is what the central bank charges banks for short-term money; the usury ceiling is the average consumer-credit rate plus a 30% margin. Consumer lending in Paraguay averages 22.91%, so the ceiling sits above a market that is already expensive relative to the policy rate.
Do Paraguay's interest rates affect the 0% tax on foreign income?
No. The territorial system taxes income by where it arises, and monetary policy has nothing to do with that test. What changes with rates is the cost of borrowing in Paraguay and the return on deposits held here, both separate questions from what you owe.
Thinking about financing part of a purchase here rather than transferring the full amount? It is worth pricing both routes before you commit, and a first conversation is a good place to set them side by side. Write to us.
