It was the lowest month-on-month increase recorded during the 2016-2020 period.
The national statistics agency said the CPI rise in September can mainly be attributed to hikes in educational costs, higher electricity prices due to increased consumption and rising rice prices.
A breakdown of goods and services showed that educational costs saw the largest increase at 2.08%, followed by a 0.62% rise in household utility bills and building materials, which was primarily created by a 3.23% hike in electricity prices and 0.52% rise in cooking gas prices.
In September, restaurant services, entertainment and tourism expenses all went down as demand was hit by the resurgence of the coronavirus.
On average the CPI in the first nine months of 2020 rose by 3.85% compared with the same period in 2019.
The domestic gold price index in September fell slightly by 0.33% compared with the previous month but shot up by 32.37% as against December 2019 and by 30.33% from the same month last year.
In the meantime, the US dollar index in September dropped 0.05% as against August, but rose 0.12% compared with December 2019, falling 0.17% from the value recorded in the same month last year.
