Inflation Reaches 3.2% in the Euro Zone

Before the Iran war, inflation in the euro zone had finally fallen below 2%, the European Central Bank's target. It had taken years of rate hikes and economic pain to get there.

Eurozone inflation results are in for May, and unsurprisingly, that progress has reversed.

Euro zone inflation rose to 3.2% in May, its highest level in nearly three years, and the ECB is widely expected to raise interest rates for the first time in almost three years at its meeting next week.

Here's what's driving it, and what it means for you as a global investor.

What's Driving It

The main culprit is energy. Prices for energy across the euro zone rose 10.9% compared with a year ago, driven almost entirely by the disruption to oil and gas flows caused by the closure of the Strait of Hormuz since the Iran war began in late February.

Services inflation also jumped, rising to 3.5% from 3% in April. That matters because services inflation tends to be stickier than energy inflation. It reflects things like wages, rents, and the cost of domestic services, which don't come down quickly even when energy prices ease.

Core inflation, which strips out food and energy to give a cleaner read on underlying price pressures, is the number the ECB watches most closely. Worryingly, it rose to 2.5% - slightly above what analysts had expected.

Why Europe Is Particularly Exposed

Europe imports the vast majority of its energy, making it especially vulnerable when global supply routes are disrupted or when major producers cut output.

Before the Iran war, a significant share of its energy that came through the Strait of Hormuz. With those flows severely disrupted, Europe’s had to source energy from elsewhere at higher cost, and those costs are feeding through into prices across the economy.

It’s good to note that inflation rates vary significantly across the euro zone - for example, Germany's inflation fell slightly to 2.7% in May, France rose from 2.5% to 2.8%, and Greece and Lithuania saw rates soar above 5%.

What the ECB Is Likely to Do Next

The ECB has been preparing the ground for a rate hike for weeks. Its chief economist and a senior board member both signalled in recent weeks that higher oil prices were feeding wider inflation and that action was needed.

A rate hike means the ECB raises its key interest rate, making borrowing more expensive across the eurozone. The expected move is a quarter of a percentage point, taking the rate to 2.25%.

That might sound small, but coming after a period when rates were close to zero and then cut repeatedly to support growth, it marks a meaningful shift in direction.

It’s a tough position to be in - raising rates is the standard tool for fighting inflation, but it does so by slowing the economy, discouraging spending and investment.

Europe is already dealing with weaker growth from the same energy shock that's driving inflation. Tightening policy into that environment is a difficult balancing act, and it's part of what makes stagflation, slow growth and rising prices simultaneously, so challenging to manage.

What This Means for You

If you're based in Europe, higher interest rates affect more than just your savings account. Mortgage rates, business borrowing costs, and consumer credit all tend to rise when central banks hike. If you're on a variable rate mortgage or considering a large purchase on credit, it's worth looking into how your payments could be affected.

If you hold bonds in your portfolio, particularly longer-dated European government bonds, it’s good to know that when interest rates go up, existing bond prices go down. That's because newer bonds will offer higher returns, making older ones less attractive. So if you hold a European bond fund right now, its value may dip in the short term.

When interest rates go up, existing bond prices go down. That's because newer bonds will offer higher returns, making older ones less attractive.

If you live outside the euro zone, you're not insulated from this.

Higher European interest rates tend to strengthen the euro, which affects exchange rates and the cost of goods traded between Europe and the rest of the world. And if Europe's economy slows significantly, that ripples through global supply chains and demand for exports from other regions too.

For investors broadly, the key question is how long this lasts. Many analysts expect the current energy shock to ease over time as supply adjusts and alternative sources become available, but that could take months or longer.

Until then, Europe faces the prospect of continued rate hikes into a slowing economy, and that combination tends to be a barrier for growth stocks and consumer-facing companies in particular.
