Polymarket traders price a 90% implied probability of a Bank of Russia key rate decrease at its April meeting, driven by the central bank's March 20 cut of 50 basis points to 15% amid disinflation progress—annual inflation slowed to 5.9% as of mid-March, with core inflation easing—and a weakening economy pressured by sanctions and slowing growth. This easing trajectory, following February's prior 50 basis point reduction from 16%, reflects monetary policy shifting toward supporting activity as price pressures normalize, outweighing a slight March uptick in household inflation expectations to 13.4%. No change lingers at 10% due to vigilance on sustainability, while hikes at 0.4% appear off the table; the April 24 decision remains the key catalyst.
