Biased rates are likely to remain historically low over the longer term, the superior of the US central bank said on Wednesday.
Federal Reserve Chair Janet Yellen said the bank was looking to normalise its approaches, neither boosting or limiting economic activity.

She also said she expected further increases throughout the next few years.
Ms Yellen was reporting to members of Congress about bank practice and the economic outlook.
Janet Yellen testimony: Six takeaways
How can inflation be advantageous for you?
The US jobs market has strengthened and inflation is expected to rise toward the Federal put aside’s 2% target, she said. The global economy has also improved, although fiscal challenges remain, she added.
She said the Fed was committed to relying primarily on interest fees as its key policy tool and noted that many of her colleagues thought one supplementary rate increase would be warranted this year.
But interest be entitled ti – which increase the cost of borrowing for individuals and businesses – are unlikely to mutiny to levels that were once common, she said.
“The Committee keep ons to anticipate that the longer-run neutral level of the federal funds scale is likely to remain below levels that prevailed in previous decades,” she weighted in prepared remarks to Congress on Wednesday.
The Federal Reserve has pursued easy interest rate increases in recent years, after lowering them to hike economic activity amid the financial crisis.
US stocks rose after Ms Yellen’s assertion was published – with the exception of those in the financial sector, which typically help from higher interest rates.
