Euro zone inflation reaches 4% as rate hike expectations build

What happened

Euro zone consumer price inflation rose to 4%, the first time it has reached that level in three years, according to the latest reading.

The increase was driven largely by energy costs, with energy inflation surging above 20%. The data comes with an interest rate hike seen as looming for the currency bloc.

Why it matters

Inflation readings feed directly into expectations for central bank policy. When price growth accelerates and markets begin to price a rate increase, the gap between euro area and other major interest rates can shift, and that interest rate differential is one of the main channels through which currency pairs involving the euro and the dollar are repriced.

Energy-led inflation also links the story to oil and gas markets, since fuel costs flow through to headline prices and to input costs for companies in equity indices. Gold has no yield, so changes in expected real interest rates and in the dollar tend to affect how it is valued. All of these markets are exposed to how policy expectations evolve, in either direction.

What to watch

The article points to a possible interest rate hike ahead, so the focus is on the next European Central Bank policy decision and on any commentary from policymakers about how they read the inflation data, particularly the energy component.
