Sept 15 (Reuters) - Spain's European Union-harmonised 12-month inflation rate rose ‌to 4.6% in August, up ‌from 3.9% in the period through July, ​final data released by the National Statistics Institute (INE) showed on Tuesday.

The INE's final data was above the ‌4.5% forecast ⁠in both the flash reading released two weeks ago ⁠and the average estimate from analysts polled by Reuters.

Core inflation, which ​strips out ​volatile fresh ​food and energy ‌prices, fell to 2.9% in the 12 months through August, slightly down from 3.0% in the period through July, the INE said.

Spanish national ‌consumer prices also ​rose 4.3% in ​the 12 ​months through August, up ‌from a 3.6% increase ​in the ​period through July, and in line with the 4.3% rate ​initially measured ‌by the INE two weeks ​ago.
