A legislative change in Argentina has redrawn the after-tax map for retail savers. Since the start of the 2026 fiscal year, interest earned on bank plazo fijo deposits—both in pesos and in dollars—has been fully exempt from income tax under Law 27802, eliminating a disparity introduced during the previous administration. The immediate effect is that the nominal annual rates advertised by banks, which range from 16 percent to 23 percent depending on the institution and whether the depositor is a client, now represent the gross return with no further state claim. For a 30-day deposit of 800,000 pesos, that translates into interest payments between roughly 10,500 and 15,100 pesos, according to data compiled by Ámbito Financiero.

Viewed from Buenos Aires, the exemption turns the plazo fijo into one of the lowest-taxed instruments available to individuals, especially when combined with its exclusion from the wealth tax (Bienes Personales) provided the funds remain on deposit at year-end. The contrast with CEDEARs—certificates representing foreign shares—is instructive. Capital gains on the sale of CEDEARs are also exempt from income tax, but any dividends paid by the underlying foreign company are taxed at the general rate, and the certificates themselves count toward the wealth-tax threshold. The fiscal treatment, tax specialists note, now hinges on the origin of the income rather than the wrapper, forcing savers to perform a more granular calculation of net returns.

In the English-speaking markets, the arithmetic is different but the underlying anxiety is the same. With UK inflation hovering around 3 percent and expected to rise, The Independent reports that easy-access accounts offering up to 5 percent—often with balance caps or time-limited bonuses—are the minimum required to preserve purchasing power. Across the Atlantic, CBS News calculates that a $35,000 high-yield savings account at 4.10 percent would generate $1,435 over 12 months, while a $90,000 long-term CD locked in at 4.20 percent for five years would yield more than $20,500. The fixed-rate structure of CDs offers certainty, but early-withdrawal penalties remain a material risk for depositors who may need liquidity.

The next factual milestone for savers in both hemispheres is the trajectory of inflation and the response of central banks. The US Federal Reserve has held rates steady, and any upward move later in the year would lift variable savings rates further. In Argentina, the real return on plazo fijo deposits will be determined by whether inflation decelerates sufficiently to turn today’s high nominal rates into positive territory. The upcoming consumer-price reports in Buenos Aires and the next policy statements from the Fed and the Bank of England will provide the data points that determine whether these instruments deliver genuine protection or merely slow the erosion of cash.
