The assessment is 'likely_true' with high confidence based on strong, corroborating evidence from multiple credible sources. Two separate market outlooks from a financial services firm and an insurance company explicitly state that 'forex intervention' by the RBI took place in December. In the context of central banking, 'forex intervention' is a standard term that strongly implies the sale of foreign currency (like the US dollar) to manage the value of the domestic currency. This primary evidence is further supported by strong contextual information. One source notes that the RBI was a net seller of US dollars in January 2022, establishing a recent pattern of this specific activity. Another source confirms the RBI has a history of being a net seller in December in previous years. While some sources mention other types of forex operations like dollar-rupee swaps, or are too vague to be conclusive, there is no evidence that contradicts the statement. The convergence of direct implications from two independent sources, combined with supporting contextual evidence, makes it highly probable that the RBI did sell US dollars in December.
