In October 2021, Siu declined to meet with Amber Poon's mother when she invited him to join her for a press conference.
On 5 January 2022, Carrie Lam announced new warnings and restrictions against social gathering due to potential COVID-19 outbreaks. One day later, it was discovered that Siu attended a birthday party hosted by Witman Hung Wai-man, with 222 guests. At least one guest tested positive with COVID-19, causing many guests to be quarantined. Sui later said that his attendance was part of community engagement and to meet stakeholders. He was ordered to take leave until 24 January. Later in June 2022, Siu said that he did not break any laws and that he is not interested in alcohol.
On 24 September 2022, Siu said that the threat of terrorists in Hong Kong was at a moderate level, and that there was no specific threats or intelligence that the city was targeted. However, Siu said "We cannot let our guard down. There are still some people going underground and using soft resistance tactics to try to incite people to come out. We will closely monitor our intelligence and see whether such acts are happening online."
In January 2023, Siu said that fake news about police must be corrected within 2 hours, and said that fake news had a big impact on the 2019–20 Hong Kong protests.
In February 2023, Siu disagreed with a reporter who asked if police were too focused on the national security law, after reports showed that crime had increased 10% from 2021 to 2022.
On 1 April 2025, Siu was sanctioned by the United States for "undermining [Hong Kong]'s protected rights and freedoms."
Siu retired from his position as Commissioner on 2 April 2025.
On 31 March 2025, i.e. two days before Raymond Siu's retirement, the United States Department of State announced sanctions on six Chinese and Hong Kong officials including Raymond Siu for their role in the crackdown on democracy advocates in Hong Kong.
In August 2022, Siu tested positive for COVID-19.
