On April 16th, according to Reuters, four sources stated that European Central Bank decision-makers are cautious about raising interest rates as early as this month, as there is no conclusive evidence that energy driven inflation shocks are spreading to a wider range or becoming deeply rooted. Sources say that the "second round effect" of inflation may still occur, and policy tightening is still on the agenda, but concrete evidence needs to be seen before taking action. A source said, "Long term inflation expectations have not yet risen, domestic inflation is slowing down, and the rise in gasoline prices is compressing disposable income, which actually limits the ability of companies to raise prices." The source added, "I cannot tell you what we will do on April 30th, but so far, I have not seen evidence supporting interest rate hikes." The source also said that the relatively weak labor market has limited the space for workers to demand higher wages. At present, the market expects the probability of a rate hike in April to be only one-fifth, but it has fully priced in the June rate hike and is expected to raise interest rates again in the autumn.
