This article analysed the aspect of optimal monetary policy in line with inflation expectations, becoming the focus of modern central banks, which have greatly relied on institutional credibility and transparency that gives topicality to the subject of research. The inflation expectations management in the Republic of Moldova is an unexplored side that would optimize the monetary policy promoted by the National Bank of Moldova. The practical research focused on defining the role of inflation expectations in Poland in order to achieve the objective of price stability, concluding a strong linear correlation between inflation and inflation expectations. At the same time, the emphasis was put on monetary policy assessment in the Republic of Moldova, based on the application of the conditionalities, which imply the inflation expectations formation, such as institutional transparency, independence and accountability. Based on the study, we concluded that the credibility of the central bank against the backdrop of central bank transparency is critical for inflation expectations anchoring. The Poland's practice would serve as an example to be followed for the Republic of Moldova in terms of inflation expectations anchoring.
