Lombard Odier said first-half net profit was 62.5 million Swiss francs (52 million euros, USD 68.2 million), while assets under management were 156 billion francs.
"These results are in line with our expectations and reflect both the investments we make towards our strategic objectives as well as the conservative use of our balance sheet," said Patrick Odier, senior managing partner of the bank founded in 1797.
"Our group is increasingly diversified, more international and more balanced between private and asset management clients and we are expanding our partnerships with financial services providers," he added.
Its first-half profit was 17.5 million francs, while assets under management or custody reached 27 billion francs.
The results flurry began on Tuesday with the private bank Pictet, founded in 1805.
It announcing a first-half profit of 203 million francs, and assets under management 404 billion francs.
Lombard Odier said its tier one capital ratio -- a benchmark of stability, which measures a bank's own top-notch funds -- was 23.8 percent.
In comparison, Mirabaud's was 19.7 percent and Pictet's, 21.7 percent.
Under global rules, banks must have a ratio of at least 4.5 percent, while Switzerland's regulator requires 7.8 percent.
Traditional Swiss banking secrecy has been under fire as governments -- notably the United States and European Union -- crack down on tax cheats who stash cash abroad.
The private banking sector caters for the super-wealthy, an increasingly globalised client group.
The complex nature of international finance has made it difficult for private bankers to feel safe with their tradition of putting their personal assets on the line.
