NEW YORK, Dec 31 (Reuters) - U.S. dollar reserves held by global central banks fell slightly in the third quarter from the prior quarter, according to data from the International Monetary Fund released on Monday.
The dollar share of IMF reserves totaled $3.80 trillion in the third quarter, or 61.4 percent of the total allocated reserves.
In the second quarter, the dollar's share stood at 61.8 percent, IMF data showed.
Global total foreign exchange holdings rose to $11.43 trillion in the third quarter from $11.14 trillion.
Global reserves are assets of central banks held in different currencies primarily used to back their liabilities. Central banks have sometimes cooperated in buying and selling official international reserves to influence exchange rates.
Euro reserves rose to US$1.50 trillion, or 24.2 percent of the total allocated reserves, in the third quarter from $1.454 trillion in the second quarter.
Since 2009, the euro's share of reserve assets has mostly been declining on concerns about the region's sovereign and economic crisis. At its peak in 2009, the euro's share of reserves reached just under 28 percent.
The yen's share fell to 3.86 percent in the third quarter from 3.89 percent in the quarter.
The IMF broke down central bank holdings in the Australian and Canadian dollars, which were previously classified under "Other Currencies."
Central banks held US$102.3 billion in the Australian currency globally as of the third quarter, up from US$101.6 billion in the second quarter.
They held US$112.5 billion in Canadian dollars, up from US$109.9 billion in the second quarter.
The Australian and Canadian dollars have been in demand since the global financial crisis as relatively safe havens. The aussie in particular was highly desired given its yield though enthusiasm has cooled compared with the loonie, based on the COFER data.
The move by the IMF earlier this year is part of a wider review to provide more transparency in global financial data. It is also a reflection of a growing trend by central banks around the world to diversify their holdings beyond the U.S. dollar, the euro and the yen.
Allocated reserves rose to $6.19 trillion in the third quarter from $6.07 trillion in the previous period.
Unallocated reserves, or those not known and believed mostly held by China, rose to $5.24 trillion in the third quarter from $5.06 trillion in the previous period.
