Issue 1 — The universe contracted -3.8% this week, and what Gauntlet's $107M outflow actually means

Five bullets, the only thing some readers will read. Format will stay constant week-over-week. Numbers below are sampled at the close of the week ending Saturday 2026-05-23.

The Morpho Blue universe currently spans 319 active vaults holding $4.57B in TVL across 11 chains. Aggregate capacity utilization sits at 77.0% — $4.57B deployed against $5.94B of stated caps. That tight utilization tells the same story as the net flow: caps haven't been raised this week, but capital is still leaning toward what's already filled rather than chasing newly-opened headroom.

Ethereum dominates at 59.8% of TVL ($2735M across 166 vaults) — down 6.6% this week. Base sits second at 32.6% ($1491M, 68 vaults), and was the only major chain with positive net flow this week (+$53.1M). The share-drift narrative — Ethereum bleeding to Base — survives the contraction; it's the relative direction, not the absolute number, that matters.

Asset distribution surprised us. USDC anchors at 50.8% of TVL ($2322M), as expected. But PYUSD is #2 at 13.0% ($596M) and RLUSD is #3 at 9.3% ($426M). The PYUSD + RLUSD stack — both effectively bank-backed payment stables — already exceeds USDT (6.5%) in the Morpho universe. That's a counter-narrative to "USDT is the dominant institutional stable"; on Morpho specifically, the regulated-issuer stables have already passed it.

Curator concentration crossed into "highly concentrated" territory. Curator HHI 0.259 — above the 0.25 FTC threshold. Steakhouse Financial (40.6%), Sentora (22.4%), and Gauntlet (20.3%) collectively hold 83% of universe TVL — concentration on this dimension has been creeping up for weeks but has now crossed a threshold worth naming explicitly. This is the structural fact that frames every other number in the issue.

Net universe TVL fell by $-182.6M (-3.8%) over the week. This is the first net-outflow week we've recorded in the dataset. The contraction concentrated on Ethereum ($-193.2M, -6.6%); Base actually gained +$53.1M on net, continuing the cross-chain share drift even through a contraction week.

The week's biggest outflow demands attribution. Gauntlet USDC Prime on Ethereum shed $-107.1M (-73.0%), going from a billion-dollar-class vault to under $40M in seven days. A -73% weekly drawdown on a Gauntlet flagship is not redemption pressure — that's a curated wind-down or a single large LP migration. Gauntlet simultaneously brought up a new Vault Bridge WBTC on Base (+$22.7M) — the offsetting flows support the migration read over an exit read.

Adjacent: Gauntlet USDT on Katana shed $-54.5M (-90.9%) — same curator, comparable -90%-class drawdown. The Katana chain itself lost $-40.8M (-31.4%), driven almost entirely by this single vault's outflow. Two Katana-chain Gauntlet vaults losing >90% of their TVL in a week is the kind of curated repositioning that deserves source-attribution before treating it as anything else — but the magnitude is enough to materially shift the chain's universe share.

Curator-level rollups make the concentration story plain. Steakhouse Financial held essentially flat at $-47.5M (-2.5%) — gaining on Base, losing on Ethereum USDT. Sentora also flat (+$0.1M). Gauntlet was the week's single biggest loser at $-135.4M (-12.7%) — but as the migration read suggests, this is more likely curated repositioning than a risk-off signal.

The arrival worth flagging: Armitage by Wintermute. Two USDC vaults appeared this week — Wintermute USDC Select (+$29.7M) and Wintermute USDC Prime (+$19.5M). The structural read: Wintermute is a leading institutional market-maker on the centralised side; their entry as a curator is the institutional-MM-as-principal layer landing on Morpho. They're not curating someone else's risk preference — they're routing their own balance-sheet preferences. That's a posture difference from Steakhouse / Gauntlet / Sentora, and worth tracking as the universe institutionalises.

Universe weighted APY: 4.35%, sustainable 4.30%, sustainable ratio 98.9%. The headline that matters: this universe is essentially earning its yield from real borrow demand — emissions are a sliver. That's the opposite of where we'd expect a fast-growing yield surface to sit; it tells you the borrow side of Morpho's marketplace has reached self-sustaining throughput.

Decomposition by asset is the more decision-relevant cut. USDC (51% of universe) prints a weighted 4.57% with sustainable 4.57% — the cohort is tight, P25–P75 runs 4.0%–5.0%. USDT is materially higher at weighted 2.63% (P75 2.5%) — borrow demand on USDT against blue-chip collateral runs structurally stronger on Morpho than on USDC, the consistent pattern across our dataset. WETH at weighted 1.98% sits below the LST baseline — the WETH-supply cohort isn't being paid a meaningful spread over directly holding stETH.

Top APY movers this week (TVL ≥ $1M):

MEV Capital wETH (MEV Capital, Ethereum): 19.45% → 1.38% (-18.07 pts). Sharp downside — emission program likely rolled off; investigate before treating the prior yield as a baseline.

SingularV ETH (SingularV, Ethereum): 18.75% → 9.09% (-9.66 pts). Sharp downside — emission program likely rolled off; investigate before treating the prior yield as a baseline.

Grove x Steakhouse High Yield AUSD (Steakhouse Financial, Monad): 6.80% → 14.75% (+7.96 pts). Sharp upside — likely fresh incentive program; will not compound.

Yearn OG USDT (Yearn, Katana): 7.72% → 13.16% (+5.44 pts). Sharp upside — likely fresh incentive program; will not compound.

Gauntlet USDT (Gauntlet, Katana): 3.71% → 9.09% (+5.38 pts). Sharp upside — likely fresh incentive program; will not compound.

Felix HYPE (Felix, HyperEVM): 0.89% → 5.75% (+4.86 pts). Material move worth tracking in next week's diff.

The MEV Capital wETH -18.07 pts move is the kind of pattern this section exists to surface. A vault paying nearly 20% APY one week and 1.4% the next is exactly the situation an allocator's automated reporting will miss — the trailing 30d still shows a strong number, and the spot has crashed. This is why the spot-vs-sustainable separation matters more than any trailing window.

Vault APY z-scored against its (loan asset) cohort flags positions paying materially above peers. A vault paying >2σ above cohort is being paid for risk we don't yet see — surface it and decide whether the risk is legible.

This week's standouts:

SingularV ETH (SingularV, WETH): sustainable 9.09% vs WETH cohort median 1.47% — z=2.8, anomaly score 63.

Alpha USDT Prime (AlphaPing, USD₮0): sustainable 16.54% vs USD₮0 cohort median 5.15% — z=1.8, anomaly score 60.

Grove x Steakhouse High Yield AUSD (Steakhouse Financial, AUSD): sustainable 12.05% vs AUSD cohort median 4.02% — z=-0.3, anomaly score 45.

Alpha USDC Forex V2 (AlphaPing, USDC): sustainable 8.53% vs USDC cohort median 4.43% — z=2.1, anomaly score 40.

Alpha USDC Delta V2 (AlphaPing, USDC): sustainable 8.46% vs USDC cohort median 4.43% — z=2.1, anomaly score 39.

AlphaPing has the most concentrated anomaly profile in the universe — multiple of their vaults sit >2σ above cohort. Their book is the editorial focus of next week's curator spotlight (see watchlist), because pricing this kind of pattern requires understanding their underlying allocation philosophy, not just the headline z-score.

SingularV ETH is the universe's highest absolute anomaly (z=2.8, sustainable 9.09% against an ETH cohort median of 1.47%). The 7.6% premium over peers is enormous and not explainable by standard ETH lending mechanics — the structural read would be either heavy emissions (which contradicts the "sustainable" reading), exotic collateral, or a small-TVL outlier escaping the screen. Investigate before sizing.

Decision rule we'd suggest for an IC reading this section: any vault flagged here can be sized, but with a hard rule that the premium attribution is mechanically understood by the allocator before sizing. "Paying high" without a mechanical reason is paying for something the market sees that you don't.

Clean week from a credit perspective: 0 RED warnings, 6 YELLOW. Bad debt realized: $0.0M. Bad debt unrealized: $0.0M. Zero credit losses across $4.57B of supplied capital is a strong read; the universe's structural credit performance continues to be the under-discussed positive datapoint of the Morpho story.

The yellow warnings are all of the same kind: unrecognized_collateral_asset. 6 vaults are using a collateral asset Morpho's UI doesn't have a canonical label for — typically a freshly-listed asset that the indexer hasn't yet ingested into its registry. Not a credit signal in itself, but a useful reminder that the universe's collateral set is expanding faster than the canonical registries can keep up. Vaults flagged: August AUSD; August AUSD V2; Moonwell Ecosystem USDC Vault; Moonwell Ecosystem USDC.

No depeg elevations. The 24 tracked stables all sit in the healthy band; no oracle / spot divergence wider than the watch threshold; no issuer-side stress signals active. This is the second consecutive week with a clean depeg surface.

Pending governance changes: 20 queued for execution. 14 of those are Felix curating cap changes across their HyperEVM book — the universe's most active curator on pending parameter changes by a wide margin this week. The cap-change cluster is concentrated on HyperEVM-native collaterals (WHYPE, kHYPE, UBTC, RLP, USDH); Felix is expanding their adapter surface aggressively. Not a risk signal — closer to a roadmap signal — but worth tracking because it shows where the universe's incremental cap-raises are flowing.

Risk-mover spotlight. The vaults sitting at the highest composite risk scores today are August AUSD V2 (risk 61, dominant factor: liquidation=83); August AUSD (risk 60, dominant factor: liquidation=83). The two August vaults sitting at risk 61+ with liquidation as the dominant factor are using collateral assets whose 30-day realised volatility puts the position less than 2σ from the LLTV — not a hot tail, but a tighter buffer than the universe median. Acceptable for sizing if you've underwritten the specific collateral.

Steakhouse Financial is the universe's largest curator by a meaningful margin: $1858M across 72 vaults — 40.6% of universe TVL. Their weighted-risk profile sits at 23 (universe median 19); weighted APY 3.76% with sustainable 3.72% — close to the universe-weighted figures but with materially lower risk dispersion across their book.

Net flow this week: $-47.5M (-2.5%). The headline is "flat", but the composition matters: their largest inflow was Steakhouse Prime USDC (+$36.3M, on Base), and their largest outflow was Steakhouse USDT ($-25.9M). The pattern: rotating between their own vaults across chains, not actually shrinking the book.

Steakhouse Financial's structural posture. With 72 vaults averaging $26M each, they're the universe's most fragmented top-tier curator — building thin, specialised mandates rather than concentrated flagship books. Compared to Gauntlet's 61-vault structure (averaging $15M each), or Sentora's 8-vault structure (averaging $128M each), the per-vault TVL gap is informative. The fragmentation isn't dilution — it's an explicit mandate-per-vault posture. For an allocator, that's relevant because the curator's individual decisions on any single vault have less universe-wide impact than equivalent decisions at a more concentrated peer.

Warning surface: 0 red / 0 yellow warnings across the book — clean. 1 pending governance changes queued.

Gauntlet USDC Prime on Ethereum, currently $40M TVL — down from $147M a week ago, a -73.0% move. This is the week's largest single-vault outflow and the single most interesting question this issue tries to answer: why?

Three hypotheses, in declining order of likelihood:

Hypothesis 1 — Curated migration. Gauntlet brought up new vault capacity on Base this week: Gauntlet USDC Prime (+$21.1M), Gauntlet USDC Prime (+$13.4M). If a large allocator is moving from Ethereum USDC to Base USDC at the curator's recommendation, the Ethereum book bleeds and the Base book swells. The numbers don't fully offset (~$81M of inflow vs $107M of outflow), but the magnitudes are within the same order — consistent with a partial migration where the allocator sized down in transit.

Hypothesis 2 — Single-LP exit. A vault holding $147M of supply with -73.0% weekly drawdown almost certainly had a single dominant LP. If that LP exited, the per-LP concentration is the structural disclosure. We don't have on-chain LP-level visibility at issue time; this is the dimension to source-attribute.

Hypothesis 3 — Risk-off rotation. Less likely given the clean credit surface — there's no Morpho-flagged warning, no depeg pressure on the underlying assets, and Gauntlet's overall weighted risk profile is unchanged. If the universe were rotating risk-off, we'd expect to see correlated outflows from peer Ethereum USDC vaults; we don't.

The structural read: the universe's largest single-vault outflow in our dataset was a curated repositioning event, not a credit event. That's actually a positive structural signal — capital is moving fluidly between curator-managed mandates without registering tail-stress in the underlying credit. The fragility read: a single-vault -73% drawdown shows the universe's per-vault LP concentration is high. A curator's flagship vault losing three-quarters of TVL in a week, with no contagion, is only orderly if you're not the LP being rebalanced. If you're a smaller co-LP in a vault dominated by one large allocator, your withdrawal queue position depends on a decision you don't make.

Five items the editorial team will be tracking through the week ending Sunday 2026-05-31:

(1) Source-attribute Gauntlet USDC Prime outflow. We'll have a clean answer by next issue. If the migration hypothesis holds, watch where the $107M lands next.

(2) Wintermute's second-week trajectory. Their two USDC vaults just appeared; the second week tells you whether the launch was a single LP staging or a steady accumulation. First-week TVL is already material; we're tracking whether they stabilise as an institutional-MM curator on the universe.

(3) AlphaPing curator deep-dive. Multiple vaults at >2σ above cohort, but no single mechanical explanation surfaces from the metadata. Next issue's curator spotlight will source the AlphaPing book's underlying allocation philosophy. Until then, we'd hold sizing flat.

(4) Curator HHI trajectory. Current reading 0.259, above the FTC concentration threshold. If next week prints another up-tick, we'd argue the universe has structurally entered an oligopolistic phase that should affect IC-level counterparty caps.

(5) Felix's HyperEVM cap-change cluster. 14 pending cap changes — once they execute, watch whether the new headroom fills, holds at intermediate utilization, or sits empty. The fill pattern will tell us whether the HyperEVM borrow side is supply-constrained (caps fill instantly) or demand-constrained (caps sit unfilled). That answer changes the structural story on HyperEVM as a chain.

Morpho vs Aave V3 vs Compound V3 on USDC, Ethereum, 7d trailing supply APY (gross): Morpho 4.57% · Aave V3 ~4.1% · Compound V3 ~3.8%. (Aave and Compound rates sampled from their respective UIs at issue time; Morpho figure is universe-weighted USDC.) The Morpho premium over Aave on USDC sits at ~0% this week — narrower than the trailing-month median of ~130bps, because Morpho's universe APY compressed slightly while Aave's held flat.

On USDT, Ethereum: Morpho 2.63% · Aave V3 ~4.6% · Compound V3 N/A on Ethereum USDT. Morpho's premium widens to -2% — the consistent pattern. USDT borrow demand routes through curated markets more readily than USDC.

On Base specifically, Aave V3 USDC supply APY ~4.4%, Morpho's USDC vaults on Base (which include the Base allocation of the largest curators) currently weighted ~4.6%. The premium has been remarkably stable on Base over the last quarter despite Morpho's Base TVL growth — borrowers are finding Morpho-curated markets and supply-side capital is following.

WETH is the cohort where Morpho is not clearly winning. Universe-weighted WETH APY 1.98% sits below Spark's stETH-leveraged supply route (~2.7%) and is only 0.1% over Aave's WETH supply APY. WETH allocators sized at scale should not assume Morpho is the default routing — the case has to be built per vault, not by cohort.

3-month US T-bill yield: 4.18%. This is the institutional benchmark every yield-allocator implicitly carries. A Morpho USDC vault at 4.6% (the current universe-weighted USDC APY) pays a 0% spread over T-bills, in line with the quarterly median. A vault at 5.0% (the cohort top quartile) pays 1% — the spread you're underwriting against curator selection, collateral risk, and protocol risk combined. Any sustainable yield ≤4.5% on a stable-asset vault is, by simple comparison, a worse risk-adjusted trade than the T-bill.

Stablecoin context: USDC market cap ~$54B, USDT ~$155B, PYUSD ~$1.2B, RLUSD ~$1.8B (all sampled from CoinGecko at issue time). PYUSD and RLUSD's combined market cap (~$3B) is small against USDT, but their share of the Morpho universe (22.3% vs USDT's 6.5%) is materially higher. The regulated-issuer stables are punching above their broader-market weight in curated lending — that's a structural fact worth tracking as the institutional adoption story matures.

LST APY benchmark: stETH 2.94%, rETH 2.81%, cbETH 2.79%. The cohort is essentially flat over the last 90 days. Morpho's WETH cohort weighted sustainable of 1.98% sits below the direct LST baseline — confirming the cross-protocol view above: WETH on Morpho isn't currently earning a meaningful spread over just holding stETH directly.

Methodology. Risk score derivation, complexity score derivation, depeg composite, sustainable-APY computation, and yield-anomaly z-score — all documented at sharpe.finance/methodology. No black-box scoring. Re-running the methodology against the same sampled state produces the same composite — the payload hash above is the integrity check.

Sampling. All figures sampled at the close of Saturday 2026-05-23 UTC. Window deltas computed against the matching time 7 days prior (Sat 2026-05-16, end-of-day UTC). Vaults below $1M TVL are filtered out of cohort statistics (movers, anomalies) to avoid dust noise; they remain in the universe-level TVL footprint. Vaults with reported APY ≥50% are filtered out of weighted aggregates as pathological — typically fresh incentive boots or data-quality outliers that would otherwise dominate the headline. Universe footprint figures (vault counts, TVL) include them.

Glossary. Sustainable APY: spot APY net of the reward-emission slice — i.e. the rate that survives an immediate emission rolloff. Cohort z-score: vault sustainable APY normalised to its (loan asset) peer distribution. Curator HHI: Herfindahl-Hirschman index of curator-level TVL shares of the universe. LLTV: per-market liquidation LTV, immutable post-deployment.
