Xinhua–Dow Jones International Financial Centers Development Index (IFCD) was a ranking of circa 45 major global financial centres, and was compiled annually by the Xinhua News Agency of China with the Chicago Mercantile Exchange and Dow Jones & Company of the United States from 2010 to 2014; the IFSC (or Dublin) ranked 37th overall of 45 centres in the final 2014 IFCD Index. Tax haven concerns IFSC growth is closely related to concern regarding tax issues, and Ireland as a tax haven, estimated in 2018 by academics to be the world's largest tax haven. The role that the major IFSC accounting and IFSC law firms have played in creating Irish tax haven-type legal structures, including Double Irish, Single malt, and Capital allowances for intangible assets (CAIA) BEPS tools, as well as Section 110 SPV, QIAIF and ICAV zero-tax legal structures, has been chronicled.
