Shanmugam says Singapore could consider anti-androgen treatment if it demonstrably reduces reoffending.
Singapore remains open to considering chemical castration for sex offenders if evidence shows it can reduce crime, although the government says current evidence remains inconclusive.
Government Keeps Option Open
Singapore is open to considering pharmacological anti-androgen treatment, commonly described as chemical castration, for sex offenders if strong evidence shows it can reduce crime, Senior Minister and Home Affairs Minister K Shanmugam said in a written parliamentary reply on September 8. However, he stressed that available evidence on its effectiveness remains inconclusive, meaning Singapore has not announced plans to introduce the measure. He was responding to Workers’ Party MP Gerald Giam, who asked about additional measures to deter sexual offenses and reduce reoffending.
Existing Penalties Already Severe
Shanmugam said Singapore already imposes substantial penalties for serious sexual offenses, particularly those involving children. Rape or penetrative sexual assault involving a child under 14 without consent carries a mandatory minimum jail term of eight years, up to 20 years, and at least 12 strokes of the cane. Outrage of modesty against a child under 14 can result in up to five years in prison, a fine, and caning, with heavier mandatory penalties where the victim is hurt or restrained.
New Regime Targets High-Risk Offenders
Singapore also introduced the Sentence for Enhanced Public Protection, or SEPP, on July 31, 2026. It applies to offenders aged 21 or older who commit serious violent or sexual crimes and pose a substantial risk of reoffending. Courts can impose a minimum detention period of between five and 20 years, after which an offender will only be released if assessed as no longer posing a threat to the public. Detention can continue beyond the minimum period if the offender is assessed as continuing to pose a threat to the public.
Screening Could Expand Around Children
The government is also considering broader criminal-record screening for jobs or roles involving sustained contact with children and young people. Police already maintain a non-public record of people convicted of serious offenses, including sexual crimes, and relevant information is shared with selected agencies when screening applicants for certain child-related positions. Authorities are studying whether such checks should cover more roles, including voluntary screening in currently unregulated sectors.
Evidence Will Determine Any Further Action
The government’s position makes clear that chemical castration is currently an option under consideration rather than an approved punishment or treatment program. Shanmugam said Singapore would consider the measure only if clear evidence shows that it can reduce crime, while noting separately that the current offender-screening system seeks to balance child protection with the rehabilitation and reintegration of former offenders.. Any future move would therefore depend on stronger evidence and further policy assessment.
Singapore’s discussion reflects a wider challenge facing criminal justice systems: how to protect the public from serious sexual offenders while ensuring that new interventions are supported by credible evidence. Singaporeans will be watching whether existing sentencing and screening measures prove sufficient before more controversial options are considered. For Indonesians, the debate also offers a regional comparison as Southeast Asian governments examine different approaches to punishment, rehabilitation, child protection, and repeat sexual offending.
