Paulo Macro — Equity Funding is Becoming an Issue
"When 'making room' goes market wide." The cost of funding equity leverage just exploded to new tights — and it's always funding constraints that end the party.
One-line take: Equity funding tightened into May month-end like a fake quarter-end window-dressing moment, then exploded to new tights after easing — a problem. And it is not a dealer balance-sheet capacity issue (swap spreads haven't gone more negative; dealer gross shorts in equity futures haven't jumped → no futures-basis trade) but raw speculative leverage demand: the HK-listed 2× Hynix ETF paying KIBOR +850 for swaps and running out of capacity (the MSTR-2×-ETF 2024 analog), prime brokers charging 3%+ on Hynix/Samsung/TSMC/Kioxia longs (longs normally earn a credit), record SPX call volume (70% of all options, per Goldman). With hundreds of billions of equity supply set to hit illiquid summer markets and ECM books running "last in, first out" to make room (SPCX/CBRS/QNT buckling), Momentum and Beta factors — and any gross exposure over its skis — are in big trouble.

| Ticker | Name | Research | View | What's said | Source |
|---|
| TSM | Taiwan Semiconductor (TSMC) | QT · SA · STK · FA | Neutral | Cited as a funding-stress example, not a stance: prime brokers were charging 3%+ to fund TSMC (and Hynix/Samsung/Kioxia) longs — abnormal, since longs normally earn a credit from PBs who rehypothecate the stock. | post ↗ |
| MSTR | MicroStrategy (Strategy) | QT · SA · STK · FA | Negative | The cautionary analog: the MSTR 2× leveraged ETFs after Trump's 2024 election were the last high-profile case of a levered ETF running out of swap capacity — "we know what's happened to MSTR (and the levered ETFs) since then." Its converts also flagged as expensive-to-fund collateral vs T-bills. | post ↗ |
This is a macro/funding piece — the only tradable names are illustrative. TSM is a passing funding-stress example (not a directional view; Neutral). MSTR is a cautionary historical analog for today's levered-ETF/swap froth. The foreign funding-stress names (SK Hynix and its HK-listed 2× long ETF, Samsung — Korea; Kioxia — Japan) are non-US-listed and cited only as examples, so they're left to the talking points rather than tabled. SPCX (SpaceX IPO), CBRS and QNT are named in passing as recent "hot-issue" supply/buckling and are not tabled here. Kevin Muir (the equity-funding primer) is a person and is excluded.
2. Talking points
Funding tightened into month-end like a fake year-end
- Heading into May month-end, equity funding tightened almost as if it were a quarter-end / year-end dealer balance-sheet window-dressing moment — "weird for May," which is why he only paid lip service to it the prior weekend.
- He wanted to see if it would stick past month-end. After easing earlier in the week, funding then exploded to new tights — "and this is a problem."
It's NOT a dealer-balance-sheet capacity issue
- If this were a dealer balance-sheet (supply) problem, you'd expect swap spreads to go much more negative — they haven't.
- There's also been no big move in dealer gross short positions in equity futures, so the rise in equity "inventory" is not dealers ramping a stock-index-futures basis trade.
- Conclusion: the funding-cost rise is simply a raw rise in demand for leverage from speculators — a leverage-demand signal, not a capacity one.
The HK 2× Hynix ETF runs out of swap capacity
- The Hong-Kong-listed 2× long SK Hynix ETF was running out of swap capacity and now has to piece together its daily 2× return via a combination of equity and options — "dealers will charge them through the teeth."
- Prime-broker friends confirmed it was already paying KIBOR +850 for swaps.
The MSTR-2×-ETF 2024 analog
- The last high-profile case of this was the MicroStrategy 2× leveraged ETFs after Trump's 2024 election — "and we know what's happened to MSTR (and the levered ETFs) since then." A pointed cautionary reference, not a rated call.
Goldman flags the levered-ETF explosion
- Goldman's recent comments on the explosion in levered ETFs are the institutional confirmation of the same froth.
Prime brokers charging to fund Asian-semi longs
- Prime brokers were charging 3% or more to fund Hynix, Samsung, TSMC, and Kioxia longs — "this does not normally happen": longs should earn a credit from PBs who rehypothecate the stock out. Paying to be long is the tell.
Record SPX call volume
- Last Friday saw the largest SPX call-volume session of all time, with calls 70% of every option traded (per Goldman) — speculation "vaulted completely off the page."
Hundreds of billions of supply into illiquid summer
- We're "right back in late 2024," heading into less-liquid summer months (volumes already woeful), with hundreds of billions of equity supply set to hit the market — requiring even more funding from grossed-up hedge funds to carry.
ECM "last in, first out" — IPOs forewarn rollovers
- A reader asked whether the SPCX IPO and the buckling of hot issues like CBRS and QNT are indicative — Paulo points back to his September primer "When IPOs Forewarn Market Rollovers": yes, we're doing this again.
- For ECM books it's "last in, first out" to make room, running headlong into funding constraints. "It's always funding constraints that end the party."
What breaks: Momentum and Beta
- He thinks Momentum and Beta factors are in big trouble here, "as are any gross exposures over their skis." Stay frosty.
Appendix — the equity-funding primer (Kevin Muir)
- What equity funding is: a client (e.g. a pension wanting S&P 500 exposure but facing a possible capital call) gains exposure via a total-return swap — receiving the index total return, paying a floating rate (SOFR / Effective Fed Funds). The bank buys and holds the stock with no market risk and charges a funding fee — the "cost of funding equity positions." As more clients ask, banks charge more (equity-concentration risk); collateral quality matters (T-bills fund far cheaper than MSTR converts). In Q4-2024 this funding cost more than tripled.
- The listed proxy: the CME now lists an Adjusted Interest Rate (AIR) Total Return future on US equity indices (Bloomberg ticker AXW) — a listed total-return swap quoted as a rate over EFF/SOFR, stripping out dividend/interest risk to leave just the cost of funding an index equity position.
3. In plain English
A jargon-free summary of why each name appears — what it is and why that view. (Plain-language companion to the table above; renders on each ticker's consolidated page.)
MSTR — MicroStrategy (Strategy) Negative
MicroStrategy (now "Strategy") is the company that turned itself into a leveraged Bitcoin holding vehicle. Paulo isn't analyzing the business here — he's using it as a warning sign. After the 2024 election, "2× leveraged" ETFs that promised double MSTR's daily move got so popular that the banks providing the leverage (via swaps) ran out of room and had to charge punishing rates; the ETFs and the stock then unwound badly. That same fingerprint — a levered ETF outgrowing the swap capacity that feeds it — is showing up again today (now in a Korean chip ETF), which is why he reaches for MSTR as the cautionary precedent.
The deeper point: how expensive it is to finance a position tells you how stretched the leverage is. Safe collateral like 3-month Treasury bills funds cheaply; speculative collateral like MSTR's convertible bonds funds dear. When the cost of funding equity bets jumps, someone is reaching hard for leverage — and that reach is usually what ends the rally.
TSM — Taiwan Semiconductor Neutral
TSMC is the world's dominant contract chipmaker. It shows up here only as evidence, not as a buy or sell call. Normally, when you hold a stock through a prime broker, the broker lends your shares to others and pays you a small credit for the privilege. Paulo's contacts say the opposite was happening: prime brokers were charging 3%+ just to let clients stay long TSMC (and Hynix, Samsung, Kioxia). Paying to be long instead of being paid is a clear sign that demand for leverage in these crowded Asian-semiconductor names had overwhelmed the supply of financing — a funding-stress tell, not a view on the company.
