European stock indexes notched gains Friday, while the euro rose after the release of inflation figures for the eurozone that may help the European Central Bank chart its next move.

After spending much of the session switching between small gains and losses, the Stoxx Europe 600 SXXP, -3.24% finished up less than 1 point at 396.37.

The pan-European index closed with a weekly gain of 0.4%. It also rose 4% in July, the best monthly performance since February. The monthly gain came during a frenetic pace of developments surrounding Greece’s debt crisis that eventually led to a restart in negotiations aimed at Greece receiving a third bailout package.

After a month of closure, the Athens Stock Exchange said late Friday that trading in Greek stocks GD, -4.28% will resume Monday.

Euro and inflation: The euro EURUSD, -0.01% on Friday, meanwhile, rose after the European Union’s statistics agency said consumer prices in July were 0.2% higher than a year earlier, meeting expectations of analysts polled by Dow Jones Newswires.

The euro later pushed above $1.11 after U.S. second-quarter employment-cost data showed wage inflation was much lower than previously suggested. The data prompted investors to shift their expectations on the timing for an interest-rate increase to December. Late Thursday, the euro bought $1.0930. Read more in Currencies.

The eurozone’s headline inflation rate remains below the ECB’s target of just under 2%. The core rate, which excludes prices for energy, food and alcohol, rose to 1%. Analysts had expected a 0.8% reading on the core rate.

“The current weakness of oil and commodity prices has increased the risk that the eurozone could briefly dip back into deflation, but it still seems probable that consumer-price inflation will trend gradually up from the final months of 2015,” said Howard Archer, chief European and U.K. economist at IHS, in a note.

Improvement in eurozone economic activity and the weak euro are among the factors that could lift inflation going forward, he said.

Separately, Eurostat said the number of people without jobs in the eurozone rose in June, by 31,000, while the jobless rate stayed at 11.1%.

Indexes: Spain’s IBEX 35 IBEX, -3.42% had been lower but recovered, ending up 0.1% at 11,180.70. The gain, however, was limited in part by a 12% slide in Obrascon Huarte Lain SA OHL, -3.84% , triggered after the construction company late Thursday said it planned to raise €1 billion euros ($1.10 billion) through a share sale. The IBEX 35 closed July with a 3.8% advance.

Germany’s DAX 30 DAX, -4.37% rose 0.5% to 11,308.99, and France’s CAC 40 PX1, -3.73% rose 0.7% to 5,082.261. The U.K.’s FTSE 100 UKX, -3.37% rose 0.4% to 6,696.28.

For the month, the DAX rose 3.3% and the CAC picked up 6.1%. The Footsie tacked on 2.7%.

Among Stoxx 600 movers on Friday, ArcelorMittal SA MT, -8.39% shares rose 1.5% as the steel-industry heavyweight said second-quarter net profit rose to $179 million from $52 million a year ago.
