Yield to maturity on Iran's Islamic treasury bills fell 0.22 percentage points to 39.58 percent in the first week of Mordad

Data from the economic and risk analysis department of Iran's Securities and Exchange Organization show that the yield to maturity on Islamic treasury bills fell 0.22 percentage points between the first day of last week and Wednesday 29 July 2026 (7 Mordad 1405), to 39.58 percent.

Between Saturday 25 July and Wednesday 29 July 2026 (3 to 7 Mordad), retail trading volume in Islamic treasury bills totalled 13,088,000 notes. The highest daily volume, about 3,423,000 notes, was recorded on 26 July (4 Mordad), and the lowest, about 2,148,000 notes, on 29 July (7 Mordad).

The yield on Islamic treasury bills is one of the main gauges of the risk free cost of funding in Iran. A lower yield reduces the cost of raising money through the debt market for both the government and companies, and it also feeds into equity valuations as the risk free rate.
