A breakdown in the relationship between dollar weakness and Asian central bank intervention poses a risk to Treasuries, stocks and all risky assets, according to Deutsche Bank AG.

Attempts by the Trump administration to clamp down on currency manipulation have limited the ability of central banks across the region to buy U.S. assets when the dollar weakens, and dampen the appreciation of their currencies, strategist Alan Ruskin write in a note Friday.

Such central bank puts are usually associated with successive Federal Reserve chairs willing to support the wider market with loose monetary policy. While such puts have been a continuous focus for investors, markets now risk overlooking other sources of central bank support that may be slipping as the U.S.’s “synergistic relationship with China,” comes to an end, according to Ruskin.

“It is not a coincidence that in this recent period of dollar weakness, Treasury bonds were also soft,” he said. “Historically, foreign central banks of sizable current account surplus countries like China, Taiwan, Korea and Thailand would have been intervening.”


According to the strategist, the “end of Chimerica” means American current account deficits are no longer financed to the same degree by Asian central bank reserve recycling of corresponding trade surpluses.
