LONDON/WASHINGTON (Reuters) - Chinese officials reviewing the country's vast foreign exchange holdings have recommended slowing or halting purchases of U.S. Treasury bonds amid a less attractive market for them and rising U.S.-China trade tensions, Bloomberg News reported on Wednesday.
The report sent U.S. Treasury yields to 10-month highs and sent the dollar lower. Economists cautioned, however, that China would not be able to make large changes to the composition of its reserves as it needs them to manage its renminbi exchange rate.China has the world's biggest currency reserves, approximately $3 trillion, and is the biggest foreign holder of U.S. government debt, with $1.19 trillion in Treasuries as of October 2017, according to data from the Treasury Department.

They also cited trade tensions with the United States as a reason to slow Treasury purchases, the report said. Bloomberg said the Chinese officials did not specify why trade tensions would cause a cutback in Treasuries purchases.U.S. Treasury Undersecretary David Malpass, speaking to reporters in Brussels, dismissed any concerns about China's demand for U.S. Treasuries."The U.S. Treasury market is a deep, robust market within the world and so we are confident that our economy, with the economy strengthening, that it will remain a deep, robust market," Malpass said when asked to comment on the report.Malpass, who heads international affairs for Treasury, also reiterated his concerns about China's emphasis on its state-owned enterprises and government subsidies that distort capital allocation.(GRAPHIC-Chinese ownership of U.S. Treasuries - http://reut.rs/2COP5Bl)LITTLE ROOM TO MANEUVERChina's State Administration of Foreign Exchange did not immediately respond to a faxed request for comment on the Bloomberg report.
