IOSCO has published a summary of its meeting to discuss and respond to the ongoing and emerging challenges facing global securities markets. Among other things, there were discussions on recent market developments and volatility in capital markets, and the challenges and opportunities posed by fintech, particularly "distributed ledger technology" (also referred to as block chain). A roundtable discussion on block chain highlighted the potential that new financial technologies can have to improve global market efficiencies and which can provide emerging market jurisdictions with the infrastructure needed to further develop their capital markets.
