Witryna8 kwi 2024 · FRANKFURT ― The markets are jittery and inflation still needs taming. Coming together, those two things put the European Central Bank in a real bind. Fight one fire and it could cause the other to flare. The ECB can keep raising interest rates to try to get inflation under control, but that risks fueling financial market tensions. raymond hibble bradford https://smidivision.com
