## 5% doesn't break things today
The 10-year Treasury yield hit its highest level since 2007. The real question is where strain emerges if rates stay elevated.

> Note that 5% doesn't break anything on the day it arrives. It breaks things twelve to eighteen months out, when the refinancing must happen
## Housing will feel it first
Mortgage rates could approach 8%, freezing transactions as homeowners with 3% mortgages refuse to sell. Homebuilders and mortgage originators will hurt.
## The refinancing clock is ticking
Companies that borrowed at 2% to 3% during the zero-rate era now face refinancing at 6% to 8%. That crushes cash flows and asset values.

> The key issue is not necessarily today's yield level, but the fact that debt raised at 2%-3% now needs to be refinanced closer to 6%-8%
## The maturity wall was delayed
Many companies extended debt maturities in 2020 and 2021, pushing the problem down the road. But the wall is coming, not gone.

> The critical point is that the maturity wall was moved, not removed
## Commercial real estate faces acute pressure
Office properties are already vulnerable. Multifamily buildings financed with floating-rate bridge loans in 2021 and 2022 face especially tough conditions.
## Duration matters more than level
Markets can absorb a temporary spike above 5%. But if yields stay elevated for six to twelve months or longer, the damage becomes unavoidable.

> Markets can typically absorb a temporary move above 5%, but a sustained period of six to twelve months or longer becomes much harder to ignore
## Watch the interest coverage ratios
Ablin is monitoring leveraged loans and private credit for signs of strain, including borrowers paying interest with more debt instead of cash.
## The margin for error is narrowing
Right now, 5% looks more like a valuation adjustment than a systemic threat. But there's less room for things to go wrong.

> At this stage I would still view 5% primarily as a valuation adjustment rather than an immediate systemic threat
## Key takeaway

A 5% Treasury yield doesn't break markets immediately, it breaks them 12 to 18 months later when debt must be refinanced at the new, higher rate.
