In a bid to spur growth and avert the dangerous threat of deflation in the sluggish eurozone economy, the European Central Bank cut its benchmark interest rate to a record low and took the unprecedented step of lowering the bank deposit rate below zero.
The announcement Thursday in Frankfurt, Germany, marks the first time that a major central bank has pushed a key rate into negative territory. Not even the Bank of Japan during its two-decade battle with deflation or the U.S. Federal Reserve in the wake of the Great Recession has tried such an unusual approach.
The negative-rate move was the most eye-catching of a series of steps unveiled by Mario Draghi, president of the ECB, who two years ago helped stabilize the eurozone by saying the central bank would do whatever it takes to preserve the euro currency.
On Thursday, he sought to express similar resolve in fighting ultralow inflation. "Are we finished? The answer is no."
By lowering the overnight bank deposit rate to negative 0.1 percent from zero, the ECB will be charging lenders to park their funds with the central bank. The hope is that this will spur banks to make more loans and also weaken the euro, helping to lift an inflation rate that dropped to a four-year low of 0.5 percent in May.
Fears of deflation, a condition of falling prices, have increased amid persistently high unemployment and constrained government budgets, particularly in the eurozone's periphery.
Deflation cuts into business profits, raises real debt burdens and discourages consumer purchases, hampering investments and jobs. The strong euro has not helped because it has damped inflation by lowering import prices while also making Europe's exports more expensive in foreign markets.
As rare as the negative deposit rate is — Denmark tried the move in 2012 but saw little effect — analysts said it isn't likely to bolster lending. For one thing, the negative 0.1 percent rate is too small to change banking behavior.
