The Turkish Statistical Institute (TÜİK) has published the real return rates for financial investment vehicles for October 2026. According to the data, while deposit interest provided the highest gain on a monthly basis, the most profitable investment vehicle on an annual basis was Government Domestic Debt Securities (DİBS).
DEPOSIT INTEREST PERFORMED BEST ON A MONTHLY BASIS

In October, the highest real return was achieved by gross deposit interest, with rates of 1.31 percent when deflated by the Domestic Producer Price Index (Yİ-ÜFE) and 0.39 percent when deflated by the Consumer Price Index (TÜFE). DİBS, which earned its investors 0.91 percent based on Yİ-ÜFE, took second place. The US Dollar, Euro, gold bullion, and the BIST 100 index were the vehicles that resulted in losses. Notably, the BIST 100 stood out as the vehicle that caused the most loss to its investors, with a rate of 14.53 percent based on Yİ-ÜFE.
THREE AND SIX-MONTH EVALUATIONS

Looking at the three-month period, deposit interest again offered the highest return to investors. Gross deposits provided a gain of 2.90 percent based on Yİ-ÜFE and 2.92 percent based on TÜFE. In this three-month period, the investment vehicle that caused the most loss was again the BIST 100 index.

In the six-month evaluation, the return table shifted in favor of DİBS. Providing a real return of 3.95 percent with Yİ-ÜFE and 5.59 percent with TÜFE, DİBS became the most profitable vehicle of this period. The BIST 100 index remained the vehicle that caused the highest rate of loss to its investors over the six-month period.
DİBS AT THE TOP IN ANNUAL RETURNS

When financial investment vehicles are examined annually, DİBS provided the highest real return. DİBS, which earned 5.96 percent with Yİ-ÜFE and 4.04 percent with TÜFE, was followed by deposit interest. In the annual evaluation, the US Dollar, gold bullion, Euro, and the BIST 100 index caused losses for their investors. The BIST 100 maintained its position at the bottom, causing a loss of 15.09 percent on an annual basis with TÜFE.
