The U.S. Federal Reserve Board is leaving its benchmark interest rate unchanged while signalling further gradual interest rate hikes in the months ahead as long as the economy stays healthy.

The Fed’s decision left the central bank’s key short-term rate at 1.75%-2% — the level hit in June when the Fed boosted the interest rate for a second time this year.

The Fed projected in June four rate hikes this year, up from three in 2017. Private economists expect the next interest rate hike to occur at the September meeting.

In a brief policy statement, the Fed notes a strengthening labour market, economic activity growing at “a strong rate” and inflation that’s reached the central bank’s target of 2% annual gains.

Although officials saw the economic risks as roughly balanced, there was no mention in the statement of what many economists see as one of the biggest risks at the moment: rising tariffs on billions of dollars of U.S. exports and imports that have been imposed as a result of U.S. President Donald Trump’s new get-tough approach on trade.

The Fed’s statement did not make any mention of the rising trade tensions or of recent criticisms Trump has lodged against the Fed’s continued interest rate hikes. Instead, the statement was decidedly upbeat about the economy, using the word “strong” three times in the opening paragraph to describe various developments.

The Fed’s decision was approved on a unanimous 8-0 vote. It was little surprise, given that this meeting followed a June session in which the Fed took several steps, including raising interest rates by another quarter-point and changing its projection for hikes this year to four from three.

The March and June interest rate hikes followed three hikes in 2017 and one each in 2015 and 2016. The Fed’s key policy rate is still at a relatively low level. However, it’s up from the record low near zero where it remained for seven years as the central bank worked to use ultra-low interest rates to lift the economy out of the Great Recession.

The string of quarter-point rate hikes is intended to prevent the economy from overheating and pushing inflation from climbing too high. But higher rates make borrowing costlier for consumers and businesses and can weigh down stock prices. Trump has made clear he has little patience for the Fed’s efforts to restrain the economy to control inflation.

“Tightening now hurts all that we have done,” Trump tweeted last month, a day after he said in a television interview that he was “not happy” with the Fed’s rate increases.

Over the past quarter-century, presidents have maintained silence in public about Fed actions, believing that lodging complaints would be counterproductive. That’s because it could produce even faster rate hikes if the central bank feels the need to convince financial markets that it will not yield to political pressure and allow inflation to rise to worrisome levels.

At the moment, economic growth is strong, rising at an annual rate of 4.1% in the quarter ended June 30, the best showing in almost four years. Unemployment is at a low 4%, and some analysts believe it will fall further when the government releases the July figures on Friday.

But there are worries as well, led by fears of what a Trump-led trade war might do to growth in the U.S. and around the world.

Many analysts believe that the possible harm from rising tariffs was a key discussion topic this week. Although trade was not mentioned in the statement, it likely will show up in the minutes of the Fed’s discussion, which will be released in three weeks.

Delivering the Fed’s semi-annual report to Congress last month, Fed Chairman Jerome Powell refrained from criticizing the Trump administration’s effort to use the threat of tariffs to try to lower trade barriers. But Powell noted that the Fed was hearing a “rising chorus of concern” from business contacts about the harm a trade war could cause.

Powell hasn’t addressed Trump’s criticism of Fed rate hikes publicly, but the chairman had previously said in a radio interview that the central bank has long operated independently in making interest-rate decisions based on what was best for the economy and not in response to political pressure.
