Treasury Buybacks Spark Dollar Debasement Fears Amid Market Pressure

The US Treasury has announced it will expand purchases of older long-dated bonds, sparking concerns about dollar debasement in foreign-exchange markets.

The move allows for at least $4 billion in buybacks, targeting securities that have faced heavy selling since late June. However, some investors see this as an attempt to relieve pressure on long-term yields, which have climbed due to a deteriorating fiscal outlook, heavy issuance, and geopolitical risk.

'There has to be a price to pay,' said Shaun Osborne, chief FX strategist at Scotiabank. 'Either in the form of higher yields, or they're going to get a concession from the US dollar.'

The concern is that policymakers may try to prevent yields from reaching market-clearing levels via buybacks, shorter-dated issuance, or other tools that reduce the duration private investors must absorb.
