ECB interest rate hike triggers global bond market volatility

The European Central Bank (ECB) has raised its key interest rates to combat persistent inflation, which reached 3.3 percent in August. The deposit rate has risen to 2.50 percent, with the main refinancing rate at 2.65 percent. This move signals that the ECB expects inflation to remain above its 2.0 percent target for an extended period, driven by external shocks such as energy crises and Middle East tensions.

This shift is causing significant ripples across global bond markets. Yields on 10-year German Bunds have risen to approximately 3.50 percent, levels not seen since 2011. Simultaneously, US Treasury yields have surged, with 30-year bonds exceeding 5.3 percent, a high not seen in decades. Similar trends are appearing in Japan, the United Kingdom, and France, as investors demand higher returns to compensate for perceived risks.

For consumers and savers, the impact is twofold. While rising rates make savings products like term deposits more attractive, they also increase the cost of borrowing for mortgages and business loans. In France, banks are increasingly offering boosted rates on non-regulated savings accounts to attract deposits as the Livret A rate remains frozen at 1.70 percent. Economists warn that while these measures aim to curb inflation, they also risk dampening economic growth and increasing the burden of national debt servicing.
