The Saudi insurance sector will grow by up to 17 per cent a year over the next five years thanks to regulation enforcement and growth in motor insurance, the Dubai-based investment bank Arqaam Capital said yesterday. Arquaam expects the Saudi insurance sector to be the least affected by weaker oil prices, budget cuts and the tightening liquidity as the enforcement of existing regulations will propel motor and medical premiums growth at a rate of 15-25 per cent and 14-16 per cent respectively. According to an Alpen Capital report released last year, the Saudi central bank has issued several new regulations regarding underwriting practices, reserving, actuarial-backed pricing and solvency requirements in the past two years, to help grow the industry.
