The era of 5% US Treasury yields is coming: a short-term "default" is not guaranteed, but pressure may emerge in 12 to 18 months.

The yield on 10-year U.S. Treasury bonds hit its highest level since 2007, fueling market anxieties. However, several industry veterans pointed out that the real risk is not that the yield will break through 5% on any given day, but rather that the longer high interest rates persist, the more difficult it will be to resolve the accumulated systemic pressure.

On September 16, CNBC reported that Jack Ablin, chief investment officer of Cresset Capital, described this risk mechanism bluntly: "5% itself won't destroy anything on the day it arrives; it will really cause damage 12 to 18 months later, when refinancing has to be done at the new interest rate." He emphasized that the danger is not the level of yields we see today, but the longer we stay at this level, the more difficult the situation could become.

The report points out that Billy Leung, investment strategist at Global X ETFs, attributes the core issue to refinancing pressure: a large amount of debt issued in 2020-2021 at interest rates of 2% to 3% now needs to be rolled over at a cost of 6% to 8%, which will directly impact cash flow, asset valuation, and credit quality . Currently, the housing market will be the first to be affected, with highly leveraged companies, commercial real estate borrowers, and private equity-backed companies also facing significant pressure.

Housing market: the first to feel the impact

The housing market is listed by many strategists as one of the most vulnerable sectors. With long-term Treasury yields soaring, 30-year mortgage rates are approaching 8%. Ablin points out that existing homeowners with mortgages holding outstanding loans at around 3% interest rates have little incentive to sell, meaning the market is facing not a massive wave of defaults, but a deep freeze in transaction volume —homebuilders, mortgage originators, title insurance companies, real estate agents, and home furnishing retailers will all be affected.

Molly Brooks, U.S. interest rate strategist at TD Securities, also lists housing as the sector most sensitive to rising long-term yields, as long-term Treasury yields directly translate into mortgage rates.

In contrast, the impact on the banking sector may be delayed. Brooks points out that in the early stages of a steepening yield curve, banks' model of financing at short-term rates and lending at long-term rates can actually help support net interest margins. However, Leung warns that if high borrowing costs persist long enough to cause a deterioration in the credit quality of real estate or corporate borrowers, banks will face greater pressure later on.

Refinancing pressure: The maturity wall has been pushed back, but not eliminated.

The deeper risks in the credit market stem from the wave of debt maturities inherited from the era of zero interest rates. Many companies extended debt maturities in 2020 and 2021, or further postponed repayments thereafter, temporarily avoiding the impact of high interest rates. But Ablin clearly points out: "The maturity wall has been moved, not removed."

Ablin said he is closely monitoring interest coverage ratios for leveraged loans and stress signals in the private credit market—especially whether borrowers are increasing the proportion of interest payments made on new debt rather than cash.

Leung specifically named several particularly vulnerable groups: leveraged loan borrowers, speculative-grade credit issuers, private equity-backed companies, and commercial real estate borrowers.

The pressure on commercial real estate is particularly pronounced. Ablin points out that office properties were already a vulnerable segment, and rising interest rates will further exacerbate the situation. He also specifically mentions multi-family residential projects financed with floating-rate bridge loans in 2021-2022—when borrowing costs were extremely low and rental growth expectations were optimistic—are now facing a double squeeze.

Duration is more important than absolute level

Strategists generally believe that the real question the market needs to answer is not whether the 10-year yield will break through 5%, but how long it will stay at that level. Leung said:

“I think duration is more important than the specific yield level. The market can usually absorb the shock of a brief breakout of 5%, but if it lasts for six to twelve months or even longer, it is hard to ignore.”

Ablin also stated that if the 5% yield remains for two to three quarters, refinancing pressure will become increasingly difficult to avoid; and the rapid rise in yields will bring another risk—disrupting hedging positions and forcing investors to hastily adjust their portfolios.

Brooks further points out that the composition of rising yields is equally crucial. If the term premium rises sharply without a corresponding improvement in economic growth expectations, it means that borrowing costs will rise unilaterally without the support of stronger economic activity, significantly narrowing the buffer.

Leung's judgment is:

"Currently, I still tend to view the 5% drop primarily as a valuation adjustment rather than an immediate systemic threat. However, the margin for error is narrowing. "
