Members of the FOMC broadly agreed on monthly caps of about $60bn for Treasuries and $35bn for agency MBS, phased in over a period of three months or "modestly longer if market conditions warrant". That amounts to asset reductions of just less than $1tn a year.
"The Fed has clearly recognised at this point that they are behind the curve," said Eric Winograd, an economist at AllianceBernstein.
Winograd added: "When you're behind the curve you have to hurry to catch up. They are now hurrying . . . They were increasing the size of the balance sheet four weeks ago. And now four weeks from now they are going to be reducing it."
Markets reacted modestly to the minutes, as the S&P 500 stock index declined about 1 per cent and the yield on the 10-year Treasury note rose by 0.06 percentage points to 2.61 per cent.
Meanwhile, the minutes showed officials are open to more aggressive rate rises this year to battle rising prices following the Fed's decision to raise the federal funds rate by a quarter of a percentage point last month — the first increase since 2018.
Many participants said one or more half-point interest rate increases at forthcoming meetings could be appropriate if inflation stays high or intensified.
If the Fed followed through with two such adjustments this year, as markets currently expect, the federal funds rate would reach a "neutral" level that neither speeds up or slows down growth by the end of the year. Officials estimate that rate to be between 2.3 per cent and 2.5 per cent.
The Fed plans to top up its asset reductions by shedding holdings of shorter-dated Treasury bills in months when the amount of longer-dated bonds maturing is below the new caps.
Officials also are considering outright sales of the Fed's agency MBS holdings once the balance sheet shrinkage is "well under way". The Fed has previously indicated that it would prefer to have only Treasuries in its portfolio.
Jim Caron, a portfolio manager at Morgan Stanley, said the fact that outright sales of agency MBS sales are being considered "speaks volumes" about the scale of monetary tightening it needs to implement in order to curtail inflation.
The minutes show central bankers want to shrink the balance sheet quickly, and much more swiftly than the previous attempt to shed assets in 2017 after the Fed's holdings had ballooned due to bond-buying in the wake of the global financial crisis that started in 2008.
Back then, the Fed capped the monthly reduction in its balance sheet at $50bn and took a year to reach that pace.
Lael Brainard, a governor who is awaiting Senate confirmation to become the Fed's next vice-chair, on Tuesday said a "rapid" reduction in the size of the balance sheet was justified given the degree to which inflation is overshooting the central bank's 2 per cent target and the strength of the labour market.
Jay Powell, Fed chair, has suggested that the expected pace of balance sheet reduction this year is roughly equivalent to a one quarter-point interest rate increase.
In the weeks since the meeting, at which a majority of officials signalled the policy rate should rise to 1.9 per cent by the end of 2022, policymakers have publicly backed an even more hawkish stance.
Mary Daly, president of the San Francisco Fed, told the Financial Times on Friday that the case for a half-point rate increase at the May meeting had grown, echoing a number of her colleagues who have in recent weeks signalled support for a faster and more forceful tightening of monetary policy.
