The top four largest banks based on assets on the balance sheet:

$3,420 Billion = £2,401 Billion: The Industrial & Commercial Bank of China
$2,826 Billion = £1,984 Billion: The China Construction Bank
$2,740 Billion = £1,924 Billion: The Agricultural Bank of China
$2,589 Billion = £1,817 Billion: The  Bank of China.

All Chinese.

The UK’s HSBC is in 6th position (just behind JP Morgan) with assets of $2,409 Billion = £1,691 Billion. To put that into context, The Hong Kong and Shanghai Banking Corporation’s assets are still larger than the annual GDP of the UK.
