Growth in Israel was supported by the migration of over 8,000 HNWIs into the country during 2015 and well performing local equity and local real estate markets, according to the 'Middle East 2016 Wealth Report' by New World Wealth.
Israel also experienced strong new business formation (particularly in the local hi-tech sector), which helped in fuelling the growth of millionaires in the country, it added.
Saudi Arabia with 54,000 was ranked in the fourth place, followed by Iran in the fifth place (32,000), Qatar (6th, 28,000), Lebanon (7th, 14,000) and Jordan (8th, 6,300).
Turkey, which topped the list in 2014 with 98,000 HNWIs, saw a significant slump of 24 per cent in the number of millionaires in 2015.

Some of the reasons for this decline were that the Turkish Lira deprecated by 20 per cent against the USD in 2015 and the Turkish stock market was down by 30 per cent in USD terms in 2015.

The report noted that several country projections (especially Turkey, Saudi Arabia and Lebanon) are constrained by ongoing political and religious tensions in the region.
Declining oil prices are also a factor. Crude oil prices declined heavily in 2014 and 2015, which will deter further business formation and construction in these countries going forward.
"Iran's strong forecast is related to the lifting of sanctions and the expected business opportunities that should be created from that," the report said.
