HONG KONG--Hong Kong's de facto central bank on Friday said it found no evidence of collusion among banks in rigging benchmarks in the $5.3-trillion-a-day foreign-exchange market.

The Hong Kong Monetary Authority, which carried out the probe as part of a global investigation, said it sought to determine whether banks in Hong Kong manipulated foreign exchange benchmark fixings, engaged in collusion or other inappropriate activities between 2008 and 2013.

While it found no evidence of benchmark rigging or collusion by banks, the HKMA did point to two failed attempts by Hong Kong-based traders to manipulate the benchmark.

One case of a "suspected attempt to influence an Asian currency benchmark fixing" by a Hong Kong-based trader at Standard Chartered Bank was found, the HKMA said, but there wasn't enough evidence to prove whether the trader actually "effected trades."

In another case, a Hong Kong-based trader at Deutsche Bank made a failed attempt to influence the U.S. dollar--Hong Kong dollar spot rate in March 2009 at the request of an overseas colleague, the HKMA said.

The HKMA's investigation was related to a global foreign exchange investigation that drew in regulators from the U.K., the U.S. and Switzerland, among others. Last month, regulators announced a series of settlements totaling nearly $4 billion with seven banks for alleged manipulation of the foreign exchange market.

The global investigation looked into whether traders from different banks were sharing information about client orders, colluding on a sequence for placing their own trades to their advantage and other improprieties.

The HKMA's probe covered 10 banks including Bank of America, Barclays Bank, BNP Paribas, Citibank, Deutsche Bank, HSBC, J.P. Morgan Chase Bank, Royal Bank of Scotland, Standard Chartered Bank, and UBS.

The HKMA's foreign exchange investigation follows its yearlong investigation into banks rigging a local benchmark interest rate between 2005 and 2012. That investigation found evidence of misconduct by UBS AG and no evidence of collusion between banks including HSBC, Deutsche Bank, Royal Bank of Scotland, Crédit Agricole, Bank of Tokyo Mitsubishi, Citibank and Société Générale SA, people with knowledge of the matter said early this year, in March.
