"The three hike people have spoken. That's why JPMorgan is up so much now," Cramer said on "Squawk on the Street," "This is the stock that's most responsive [to possible rate hikes]."
"Be aware that's what's going on. The money is flowing out of retail right into the banks."
On Tuesday, three Fed officials indicated the central bank may raise rates again soon.
Dallas Fed President Robert Kaplan said the U.S. economy is strong enough to justify an interest-rate hike in the "not too distant future," but increases will be very gradual.
San Francisco Fed President John Williams and Atlanta Fed President Dennis Lockhart both said the central bank's June meeting was a "live" one.
In Fed jargon, a "live" meeting is one at which officials could debate whether to raise their benchmark short-term interest rate, which since December has been in a range between 0.25 percent and 0.50 percent.
