His main practice areas are Financial Services Regulatory, FinTech (including blockchain, digital assets and AI in finance), and Derivatives & Structured Products (both transactional and regulatory).
In the regulatory space, he has advised financial institutions on the regulatory landscape in Singapore, including licensing and regulatory requirements applicable to financial market infrastructures, banks, securities and derivatives dealers, fund managers, financial advisers and other financial intermediaries, and derivatives trade reporting, clearing, trading, and margin requirements. He has also advised on carbon credit projects and transactions, FinTech providers (including prospective digital bank, AI solutions providers, crowdfunding platforms, robo-advisers and payment service providers), blockchain platforms, cryptocurrency/digital token exchanges, dApp and DeFi projects, tokenisation projects, metaverse and game companies, as well as initial coin offerings (ICO) / security token offerings (STO) and issuers of stablecoins and non-fungible tokens (NFTs), on various licensing, regulatory and transactional matters.
In the derivatives transactional space, he has assisted numerous clients (including general corporates and regulated entities such as banks, insurance companies and REITs) with the preparation, review and/or negotiation of their derivatives documentation, including the International Swaps and Derivatives Association (ISDA) master agreements, confirmations and credit support and collateral management documentation.
Sion Yoong also has experience with bond issuances, structured note programmes, securitisations and other forms of structured finance. He also has prior experience as in-house counsel in a major investment bank supporting its foreign exchange (FX), rates and credit trading businesses in both transactional and regulatory matters.
Work Highlights
Significant transactions that Sion Yoong has been involved in include advising / acting for the following:
- EFG Bank on the unique regulatory issues which arose from the statutory transfer of business being effected from BSI Bank, whose regulatory status as an approved merchant bank in Singapore was being withdrawn by the Monetary Authority of Singapore (“MAS”). The statutory transfer of business took place as a parallel process to the global acquisition of BSI and its subsidiaries by EFG International. This was the first time in over 30 years that MAS had ordered a merchant bank to be shut down.
- A major bank with a global presence in Asia, UK and U.S. in relation to its project involving the issuance of fiat-backed stablecoins and the development of cross-border payment rails using blockchain technology. This stablecoin project aims to enable faster and more transparent cross-border payments, lowering costs and complexity for the bank’s customers.
- A major video game / interactive entertainment software company on financial regulatory and licensing issues under Singapore law in relation to its proposed global launch of an online gaming platform incorporating the use of NFTs, cryptocurrencies and other GameFi elements.
- A US company in relation to the issuance of digital tokens that represent a portfolio of voluntary carbon credits managed by it on an unallocated basis.
- Coinhako, a Singapore-incorporated digital assets service provider, on the financial services licensing and regulatory requirements under the Payment Services Act 2019 (“PSA”) applicable to its operation of a cryptocurrency exchange, and the various other incidental services that it intends to carry out. We have assisted Coinhako in becoming among the first cryptocurrency exchanges to successfully obtain a payment services licence under the PSA to provide digital payment token services.
- A major European bank on legal and regulatory issues pertaining to the issuance of equity-linked retail structured notes in Singapore.
