  • New Anti-Money Laundering Law

    The new anti-money laundering ( AML ) law of the UAE took effect at the end of October 2018. Containing features recommended by the Financial Action Task Force ( FATF ), the new law introduces subtle but important changes to the AML landscape in the UAE. 
  • Confidentiality Under Renewed Focus

    The UAE federal government has recently issued a raft of important legislation, addressing and in many ways updating areas of law that are key to businesses in the jurisdiction. Amongst this legislation is Federal Decree-Law 14 of 2018 concerning the central bank and the organisation of financial institutions and activities (the New Banking Law ) and Federal Decree-Law 20 of 2018 concerning anti-money laundering and anti-terrorism financing (the New AML Law ). Both the New Banking Law and the New AML Law repeal and replace the previous legislation on their respective subjects. Importantly, the New Banking Law and the New AML Law have together enhanced the protection afforded to confidential information under UAE law, in particular where financial and legal service providers and their customers and clients are concerned. 
  • Israel Chapter in The Virtual Currency Regulation Review

    Earlier this year, the Israel Tax Authority (ITA) issued two circulars, one on the taxation of digital tokens and the second addressing the taxation of utility tokens in initial coin offerings (ICOs). Additionally, in March, the Israel Securities Authority (ISA) released a detailed interim report by the Committee for the Regulation of Public Offerings of Decentralized Cryptocurrency Coins (Report) (with a follow-up report due to come out around October 2018). Moreover, it is expected that before the end of 2018, legislation will come into force that for the first time will see Israeli primary legislation define virtual currencies as financial assets and mandate licensing for related services, as is later discussed in detail.
