Bond Market Could Trigger $110B Selloff If 20-Year Yield Hits 6%

The next downturn on Wall Street may originate in bonds. Strategist Harley Bassman has cautioned that a rise in 20-year US Treasury yields to 6% could activate trading rules, resulting in selling pressure comparable to $110 billion in bond sales.

Equities and Bitcoin could be affected as investors rotate into safer government debt.

Why Is the 6% Treasury Yield So Dangerous?

The 20-year yield was around 5.68% in Bassman's October 13 report, only 0.32 percentage points below his threshold.

The issue concerns roughly $200 billion in Treasury futures. These contracts allow sellers to pick which bonds to deliver. As yields increase, longer-dated bonds may become the cheapest option. They also decline more in value when rates rise.

Managers trying to manage their exposure might then sell or hedge more bonds, pushing prices lower and yields higher.

Bassman estimated:

“such a delivery switch would be equivalent to the Treasury auctioning $110bn 20yr bonds over the course of four months,”

That figure represents possible market pressure, not confirmed sales.

BOND EXPERT WARNS OF $110 BILLION SELLING SHOCK IF TREASURY YIELDS HIT 6%

Veteran bond strategist Harley Bassman warns of a “nightmare scenario” in U.S. Treasuries.

Could the Stock Market Be Next?

Higher Treasury yields provide investors with more income from government debt and make borrowing more expensive for companies. Both factors can weigh on stocks, particularly costly technology shares.

Bank of America's survey flagged another level: 5.9% on the 10-year Treasury would lead managers to prefer bonds over equities. On Tuesday, it stood at 5.22%.

What Does This Mean for Bitcoin?

Bitcoin was trading near $83,014 on Tuesday. Climbing yields can draw investors away from riskier assets, putting pressure on crypto. Bitunix has already connected recent weakness in crypto to rising US borrowing costs.

Neither threshold guarantees a crash. However, a sharp rise in yields could affect both markets before those levels are reached.

Bassman sees a deeper issue in Washington's 6.2% fiscal deficit:

“…we have a problem of “Trust”, not inflation,”
