The committee sees a favorable US economic outlook, according to Powell. Powell referred to Wednesday's cut simply as a "midcycle adjustment", meaning further rate cuts later this year aren't a done deal.
"I'm contrasting it there with the beginning, for example, the beginning of a lengthy cutting cycle".
The normalisation process which started under Janet Yellen, saw interest rates rise cautiously from 0.25% to a "high" of 2.5% over the period between December 2016 and December 2019 as the Fed sought to "re-arm" its main anti-inflation and economic stimulus weapon, the interest rate.
The Dow Jones Industrial Average fell 188.95 points, or 0.71%, to 26,394.47, the S&P 500 lost 28.59 points, or 0.97%, to 2,924.97 and the Nasdaq Composite dropped 132.18 points, or 1.63%, to 7,978.94.
Trade uncertainty has been weighing on business investment spending, and this latest escalation only adds to it.
If other central banks respond to the Fed decision it would, of course, set Trump off again, and also increase the likelihood of the U.S. adding a currency war to its trade wars - something Trump has been seriously contemplating and hasn't ruled out.
The tariffs "are a problem because they lead to slower global and domestic growth, which is why it's being reflected in lower interest rates", said Steven Ricchiuto, chief US economist at Mizuho Securities USA LLC.
Following the cut, the US dollar rose in sympathy with US Treasury note prices, but that move had largely been retraced on Friday.

Huawei, which overtook Apple in total smartphone sales previous year , increased its shipments by 31% during the same period. President Trump signaled Washington would be relaxing the sanctions on Huawei, though details are unknown.
Powell played down financial stability concerns during a press conference Wednesday to explain the decision to cut rates, saying that while he took them seriously, "as I look at today's situation, I don't see them as a reason not to take this action today".
In our view, the Fed's rate cut is an effort to manage this risk, and it appears to have worked.
As a result, economic markets took another nosedive Thursday and Friday, with stocks and crude oil falling to six-week lows on expectations for a slowing USA economy if Americans must cut back to pay higher prices for Chinese goods.
The downside risks to the Fed's outlook came from weakening global growth and global manufacturing, particularly in the European Union and China, he noted.
USA crude rose 3.02% to $55.58 per barrel and Brent was last at $61.78, up 2.12% on the day. There was central bank activity in Japan and the United Kingdom, but the Federal Reserve was the trigger for the bullish price action, while President Donald Trump was the biggest influence on the bearish side. He began openly criticizing the central bank and its chief in 2018 for increasing interest rates and slowing the economy. Powell cited trade uncertainty as one reason the Fed had made a decision to cut rates.
In a sharp turn from December's decision, Fed officials chose to pause their steady campaign of raising rates due to an uncertain outlook for the US and global economy.
The Stoxx Europe 600 Index decreased 2.5%, the lowest in more than six weeks.
It remains to be seen if this decline in interest rates will be a one-off, or the first in a series of cuts.
