Global risk appetite surged on Monday, boosting stocks and initially denting haven assets, after Dubai said it had received $10bn from Abu Dhabi to help cover its debts. The FTSE World index rose 0.8% with financial groups particularly strong in Europe as traders bet that the loan would curb any contagion from Dubai’s woes. Sentiment was also boosted by the return of ‘mega-merger Monday’ as ExxonMobil, the giant US energy group, said it would pay $31bn in shares to buy XTO Energy.
