One of the banks to suffer more heavily than others was EFG International, the Swiss private bank. It reported a minus of 11.4 percent. UBS posted a decline of 6.7 percent and Goldman Sachs one measuring as much as 8.7 percent.

Union Bancaire Privée (UBP), which has its headquarters in Geneva, by contrast, had a very positive development, with an increase of 7 percent. This was in no small degree due to the addition of more relationship managers. Credit Suisse also had a plus, adding 1.5 percent to its tally as the bank for entrepreneurs strategy seemed to bear fruit.

What makes the increase at Credit Suisse all the more surprising is the feat that this was achieved with fewer relationship managers (580 instead of 590). Over at UBS, assets under management fell despite the fact that it had added 101 relationship managers to the total (1,138 vs. 1,037).

The Biggest Book per Relationship Manager

With $882 million, Goldman Sachs is managing the biggest amount of money per relationship manager in the region. The average relationship manager in Asia has $305 million under his guard.
