Basel III Endgame & CRE Lending: Why Banks Are Pulling Back—And Why Private Capital Is Stepping In

New capital rules take effect in 2025–27, pushing traditional lenders to the sidelines just when commercial deals need fresh fuel. Here’s what the Basel III “Endgame” means for rates, leverage, and the massive opportunity opening for private debt.

1 | Basel III Endgame in Plain English

The Basel III Endgame (a.k.a. the “finalization package”) is the last wave of post-GFC bank-capital reforms. The U.S. version—unveiled July 2024, final rule expected late 2025—will:

Requirement Old Rule Endgame Rule Impact
Credit-Risk Weighting 100 % risk weight on most CRE loans 130–150 % for > 90 % LTV or certain property types Banks must hold 30–50 % more capital per dollar lent
Operational-Risk Add-On Only for big G-SIBs Extends to banks ≥ $100 B assets Regional banks pay capital “tax” on every business line
Output Floor Not applied 72.5 % of standardized model regardless of internal rating Less wiggle room to “model” capital lower

Translation: The same $25 M multifamily loan now eats more balance-sheet capacity—so banks will raise spreads, slash leverage, or decline altogether.

2 | Early Signs: Banks Hit the Brakes

  • CRE Net-Share of C&I Loan Growth turned negative in Q1 2025 for the first time since 2013 (Fed H.8 data).

  • Construction-Loan Originations at large regionals down 32 % YoY by April 2025 (MBA survey).

  • Refi Pull-Through < 60 % for maturing office loans; banks either extend short or ask borrowers to pay down principal 10–15 %.

Expect the trend to accelerate once the final rule is inked.

3 | How the Rule Changes Deal Math

Factor 2023 Bank Loan 2025–26 Bank Loan Private Debt (LoanFunders.com)
Max LTV (Stabilized Multifamily) 75 % 65–70 % 75 % (DSCR-based)
Construction LTC 80 % of cost 70–75 % Up to 90 % (experienced sponsor)
Rate Spread vs. Treasuries +200 bp +275 bp (risk-based capital) +350–450 bp (shorter term)
Recourse Often full or partial More likely full Generally non-recourse (bad-boy carve-outs)
Closing Timeline 60–90 days 90+ days 10–30 days

Key takeaway: Even if the coupon looks lower at a bank, reduced leverage and slower closing can make private capital more attractive—especially for value-add or time-sensitive plays.

4 | Who Gets Hit Hardest?

  1. Office & Retail Re-Fi – High vacancy + higher risk weights → banks say “come back with 55 % LTV.”

  2. Ground-Up Construction – Operational-risk add-on makes construction loans balance-sheet poison.

  3. Bridge-to-Stabilization – Transitional assets (≤ 80 % occupancy) attract a 150 % risk weight under Basel.

  4. Small-Balance Investors – Regional/community banks (< $100 B) once loved sub-$10 M loans; new rules raise capital cost with no securitization outlet.

6 | Case Study – Office-to-Industrial Conversion

Before Basel Endgame: Regional bank quoted 75 % LTC, SOFR + 325 bp, 18-month term.
After Proposal: Same bank capped LTC at 60 %, demanded full recourse, and bumped spread to +425 bp.
Private Solution: LoanFunders.com bridge at 80 % LTC, SOFR + 475 bp, non-recourse. Higher coupon, but leverage returned $3 M cash to the sponsor and closed 45 days faster—enough to lock purchase contract and start demo before a competing buyer appeared.

IRR delta: +4.2 % vs. bank option.

7 | Action Plan for Investors & Brokers

  1. Pre-Test Bank Appetite – Ask local lenders how they plan to treat “output floor” capital; if unsure, line up private quotes.

  2. Model Dual Scenarios – Compare 65 % LTV bank loan vs. 90 % LTC bridge: run equity IRR, not just rate.

  3. Tell the Value-Add Story Early – Private lenders adjudicate on exit DSCR; show pro-forma NOI and costs in detail.

  4. Factor Rate Caps into Exit – Higher private coupons can be offset by shorter term; use cap-rate compression after stabilization to refi into agency/CMBS.

  5. Lean on White-Label Partnerships – Brokers, keep the relationship—and let us do the underwriting heavy lift.

8 | Conclusion—Capital Hasn’t Left the Building; It Just Changed Doors

Basel III Endgame doesn’t kill deals; it just changes who funds them. Banks will conserve capital. Private lenders like LoanFunders.com thrive on agility, higher leverage, and speed—exactly what transitional assets and opportunistic investors need.
