Trading of charges by rival political leaders thus marked the first anniversary of demonetisation in Bihar.
Although his Janata Dal (United) did not actively participate in any programme organised on the day, Nitish Kumar took to social media to congratulate the Centre.
"Demonetisation was an effective action against black money. Attack has now begun on benami properties. Congratulations to the Centre," he tweeted.
The BJP observed the first anniversary of demonetisation as "Anti-Black Money Day" across the country, while the Congress-led opposition marked the day as "Black Day".

BJP state unit chief Nityanand Rai claimed that note ban led to "a significant decline in Naxal activities and terrorism in Kashmir".
In Gaya district, Union Minister Giriraj Singh took part in a party programme and attacked the RJD for organising protest over GST and hit out at its leader Lalu Prasad who he said has made himself known as "embodiment of corruption".
Prasad, whose party staged demonstrations across the state, had earlier said in Patna that demonetisation had helped "convert black money into white with greater ease".
The Congress, which is the RJD's ally in Bihar, held anti-note ban programmes separately.
In the morning, a demonstration was staged near the collectorate and a candle light march was taken out in the evening in memory of those who lost their lives due to hardships faced in the wake of demonetisation.
