Carson Block: “Perfect Macro Storm” To Hit Blackstone Mortgage Trust

Episode Summary

Executive Summary: Carson Block argues Blackstone Mortgage Trust faces material equity downside due to floating-rate commercial real estate loans that no longer cover debt service, especially office exposure. He says rate swaps have temporarily masked stress, but as 2021-vintage loans mature and swaps roll off, refinancing, PIK interest, and dividend cuts are likely. He sees lenders protected, but equity at risk.

Main Topics: Why BXMT Became a Short (Priority: 5/5): Block explains that granular CLO data revealed most of BXMT’s U.S. loan book was exposed to cash-flow stress, unlike what 10-K disclosures showed. Floating-Rate Debt and Expiring Hedges (Priority: 5/5): He details how interest-only loans tied to SOFR became uneconomic as rates rose, while prior swaps/caps only temporarily shielded borrowers. Collateral Value Deterioration (Priority: 5/5): Higher rates, weaker office demand, lower NOI, and higher operating costs are reducing property values and making refinancing difficult. Liquidity and Funding Pressure at BXMT (Priority: 4/5): Block argues BXMT may face a liquidity squeeze because unfunded commitments exceed borrowing capacity and lender covenants may be tightening. Dividend Sustainability and Accounting Signals (Priority: 4/5): He says BXMT’s dividend looks vulnerable, noting only a minority is covered by GAAP income and that new disclosures signal legal caution. Blackstone Mothership Bailout Risk (Priority: 3/5): The interview assesses whether Blackstone Inc. would rescue BXMT; Block thinks lenders may be accommodated, but equity holders are unlikely to be bailed out.

Key Arguments: BXMT’s U.S. loan book is unusually transparent through CLO data, revealing stress that is hard to see in standard filings. A large share of loans cannot cover current floating-rate debt service without swaps, and those swaps are expiring. Office and some mixed-use collateral values have fallen because NOI is down, operating costs are up, and cap rates have risen. The biggest risk is the 2021 vintage, which was originated in a low-rate, high-liquidity environment and is now coming due. Even if borrowers can extend, refinancing at current LTVs is difficult because property values have likely fallen 20% to 50% in the stressed groups. BXMT may already be seeing distress through PIK interest and sponsor equity injections, with more stress likely in 2024. The dividend appears fragile because a large share is not covered by GAAP earnings, despite management’s non-GAAP coverage claims. Blackstone may work with lenders to avoid a creditor event, but Block doubts it will support BXMT equity holders in a full bailout.

Data Points: BXMT loan book size: $23 billion - Total loan book referenced in the discussion of maturity and swap risk. BXMT total loans: 185 loans - Overall number of loans in BXMT’s book. Loans in CLOs analyzed: 37 loans - Subset of BXMT loans found in three sponsored CLOs and used for granular analysis. U.S. loan book share: 64% - Blackstone IR said the CLO loans were representative of the U.S. loan book. Group A share by number: a little north of 25% - Loans unable to cover SOFR, let alone the spread. Group A share by value: close to 30% - Value share of loans unable to cover SOFR. Group B share by number: 45% - Loans that can cover SOFR but not the spread. Group B share by value: 49% - Value share of loans that can cover SOFR but not the spread. Combined stressed loans: about 73% by number / 75% by value - Loans in CLOs that cannot make interest payments at current rates absent hedges or sponsor support. SOFR: 5.3% - Current reference rate used in the borrower cash-flow analysis. Average spread: 330 bps - Average loan spread above SOFR. Typical all-in borrower rate: about 8.5% - SOFR plus spread, the approximate current cost of debt. PIK interest: 4% to 5% - Portion of interest already being paid in kind on BXMT’s existing loan book. Sponsor equity support / additional equity: roughly 5% to 6% - Management disclosure and Block’s reading suggest sponsors have been injecting equity to keep loans current. Troubled loan share so far: about 10% to 12% - Block’s estimate combining PIK loans and loans requiring sponsor support. 2021 vintage size: about $9 billion - Largest vintage, expected to begin maturing next year. 2021 vintage share of book: north of 40% - Share of total loan book expected to face maturity and swap expiration risk. Unfunded loan commitments: $2.7 billion - Mostly construction loans BXMT may still need to fund. Borrowing capacity: $1.5 billion - Available capacity versus unfunded commitments. Collateral covenant threshold: 80% - General lender requirement referenced for BXMT’s own financing. Estimated value impairment, Group B: almost 20% - Average impairment estimate for loans that cover SOFR but not the spread. Estimated value impairment, Group A: 50% - Average impairment estimate for loans that cannot cover SOFR. Dividend coverage via GAAP income: 27% - Disclosure in Q3 presentation fine print showing low GAAP coverage of the dividend. Non-GAAP dividend coverage ratio: 126% - Management’s headline measure discussed as potentially misleading. Potential SOFR level needed for relief: 3.5% (350 bps) - Block says only a sharp Fed cut without economic weakness meaningfully helps BXMT. Rate swaps terminating in 2024: about $16 billion - Swaps expiring against the $23 billion loan book, increasing exposure.

Pivotal Quotes: "we do think that the equity will ultimately take significant losses being that it's at the bottom of the capital stack here." — Carson Block: Explaining that creditors are relatively protected while BXMT shareholders bear the main downside. "we think that the signs of stress or actual distress, real distress will show up in the loan book next year, especially in the back half of 24." — Carson Block: His timing view for worsening loan performance as maturities and swap expirations hit. "I would be very surprised if BX, you know, actually bails out the equity holders here." — Carson Block: Responding to the idea that Blackstone’s mothership might rescue BXMT shareholders.

Implications: Listeners should view BXMT as a highly rate-sensitive equity with mounting refinancing and dividend risk. For CRE lenders broadly, the interview suggests late-2021 vintages may reveal more distress as hedges expire and capital values reset.
