FRANKFURT, Germany (AP) — The European Central Bank is stressing that interest rates will stay low well into next year even as the U.S. Federal Reserve is expected to keep raising rates in coming months.

The central bank for the 19 countries that use the euro left its key rates and monetary stimulus settings unchanged at a meeting Thursday at its headquarters in Frankfurt, Germany.

ECB President head Mario Draghi’s told a news conference that while the eurozone economy is enjoying solid growth, “significant monetary policy stimulus is still needed.”

The bank had said at the previous meeting, on June 14, that it would phase out its 2.4 trillion-euro ($2.8 trillion) bond-buying stimulus program by year-end, and would keep interest rates on hold “through the summer” of 2019. Speculation on what “through the summer” means has ranged from July to September or even later. Draghi declined to be more precise during the news conference.

The ECB is withdrawing stimulus as the economy grows, but doing it so slowly that its path is diverging sharply from that of the Fed, which is already raising rates. The Fed has withdrawn stimulus more quickly because the U.S. economy emerged sooner from the Great Recession, and now has lower unemployment.

The rich world’s major central banks — also including the Bank of England and the Bank of Japan— are slowly withdrawing stimulus measures they deployed to support the economy during and after the global financial crisis and Great Recession.

The end of the stimulus will have wide-ranging effects, such as increasing borrowing costs for governments and home buyers. By raising returns on safe assets such as bonds and savings accounts, it could also make those holdings more attractive relative to stocks and change investor attitudes toward the risks of the longstanding bull market. The ECB is proceeding gingerly to avoid market disruptions.

ECB officials have expressed confidence that inflation is sustainably trending toward their goal of just under 2 percent. It came in at 2 percent in June, although when excluding volatile items like oil and food, prices remain weaker. The central bankers are still keeping a wary eye on recent signs of weaker growth, and on the chance that a trade conflict between the United States and other countries could hurt global business and the export-dependent European economy.

Draghi welcomed a tentative agreement between the EU and U.S. on Wednesday that put a halt to any new tariffs and sought to reduce existing ones.

“It shows that there is a willingness to discuss trade issues in a multilateral trade framework again,” he said.

Lower exchange rates in the eurozone can help keep the euro’s exchange rate lower against the dollar, which helps European exporters.

The ECB’s short-term benchmark rate was kept unchanged at a record low of zero. By comparison, the Fed’s key rate is in a range between 1.75 percent and 2 percent and more increases are expected this year. The bond-buying program, meanwhile, pumps newly created money into the banking system in an attempt to raise inflation and growth by making credit easier to get.
