ANALYSIS: Mark Burke saga is a strong test of DA’s good governance swagger
DA federal chairperson and Deputy Minister of Finance Ashor Sarupen’s decision to play defence for DA federal finance boss Mark Burke after news of the Reserve Bank probe into Kastelo is a strange one, but you can understand why he did it.
The saga surrounding DA federal finance boss Mark Burke is a test of the Democratic Alliance's (DA) commitment to good governance. Ashor Sarupen, the DA federal chairperson and Deputy Minister of Finance, chose to defend Burke after the Reserve Bank initiated a probe into Kastelo, a company linked to Burke. Despite no court judgment being handed down implicating Burke in wrongdoing, the company was accused of orchestrating a massive scheme that illegally moved at least R4 billion out of the country in 2025.
Burke, who holds a PhD in econometrics and quantitative economics from the University of Cambridge, founded Kastelo with his brother. The Reserve Bank's Financial Surveillance Department (FinSurv) traced the chain of events, alleging that Kastelo paid ordinary people small bonuses for using their personal allowances, loaned money to individuals to fund offshore transfers, and used the funds for algorithmic trading in the cryptocurrency market.
The company was registered strictly as a middleman, but the Sarb argues Kastelo broke this rule by acting as the main trader, buying and selling foreign currency for its own profit.
Burke resigned from Kastelo in 2024 but claims he remained chairperson of the broader Kastelo group until February 2026. This contradicts the DA's own ethical governance standards, which require proper conflict-of-interest vetting before appointments. Burke's primary defense rests on a 'tick-box' partition between the holding entity and the company, but as group chairperson, he was responsible for corporate governance across the entire group.
The DA's Public Administration Policy (2023) and recent ethics statements call for mandatory lifestyle audits for public representatives suspected of financial malfeasance and accountability for officials.
