The bank's main rate remains at an all-time low of 3.5 percent.
'This decision is in line with expectations and I wouldn't expect significant changes to the statement, with the council remaining in neutral policy bias,' said Maciej Reluga, chief economist at Bank Zachodni WBK in Warsaw.
'Changes can be expected mid-year, with hikes in the fourth quarter.'
The bank will hold a news conference and release a statement explaining its decision at 1300 GMT.
Earlier on Wednesday Deputy Finance Minister Ludwik Kotecki said he expected inflation to ease to about 2.6 percent in March from 2.9 percent a month before.
The central bank's 10-strong Monetary Policy Council (MPC) targets inflation at 2.5 percent and most analysts expect the figure to ease further in the coming months.
At the same time retail sales and construction sector data from January and February raised analysts eyebrows and cast some doubts over the pace of the recovery and rate hike prospects later in the year.
Retail sales inched up 0.1 percent year-on-year in February and some analysts attributed the weak figure to frosty winter weather.
A Reuters poll showed earlier in March median forecast for gross domestic product (GDP) growth in the first quarter stood at 3.0 percent, but a recent finance ministry forecast put growth in the first three months at 2.5-2.8 percent.
