China announced six separate measures (rate cuts, RRR cuts, mortgage refinancing, mutual fund lending, corporate buyback lending, local government real estate support) all at once to make the stimulus package appear large and powerful when individually weak, like firing a machine gun's pea-sized shots rather than a single bazooka.

Chinese consumers will 'continue to suck wind' (remain weak) due to ongoing deflationary dynamics and precautionary savings, limiting the effectiveness of consumption-based stimulus

Chinese banks rallying 50% in three weeks were pricing in recovery as if the housing bust never happened, which is disconnected from economic reality where property developers face genuine credit constraints and pre-sale liabilities totaling trillions

Credit growth in China at 8.2% year-over-year is the lowest in 25 years, compared to 15% compounded growth from early 2000s until the pandemic; at 8% growth, the system cannot sustain itself because new credit must fund new construction or GDP falls.

Banks in China are making what McCarthy calls 'black hole loans' to property developers to finish unfinished apartment buildings; these loans default economically even if they are rolled because the underlying projects are fundamentally uneconomic

China has accumulated approximately 2 trillion dollars of presale real estate liabilities (prepayments by home buyers for unfinished apartments); if developers stopped building, millions of households who paid in advance would be left with nothing

There is no way to escape debt deflation without extremely reflationary monetary policy (QE, helicopter drops), and there is no way to achieve reflationary monetary policy while maintaining a currency peg against the dollar, which China currently has and seems unwilling to change.

Chinese local governments spent money on wasteful infrastructure projects (multiple airports in tier-3 cities, unnecessary projects) at egregious rates for an extended period, destroying capital efficiency and justifying the government transition toward 'high quality development' and reduced spending.

China's Ponzi scheme is unwinding rather than collapsing, characterized by an ongoing nonlinear slowdown in the Chinese economy and accumulation of debt that will continue until China delinks its currency from the dollar.

If China pursues fiscal stimulus while maintaining the currency peg, it will mechanistically sterilize or offset any fiscal easing to prevent currency depreciation, rendering stimulus self-defeating, as demonstrated by Japan's 1990-2005 experience where government deficits rose from 8-12% while private credit declined, leaving total credit flat.

China's announced stimulus in late September is mostly window dressing; the PBOC rate cuts were ineffective (existing mortgage rates already fallen, refinancing does not move the dial on growth), and funding facilities to mutual funds and stock buyback programs will have marginal impact on economic growth.

The government must increasingly borrow and spend because private sector actors refuse to borrow in deflation; companies won't take new credit when they can't invest money at positive real rates; households won't borrow when prices are falling and cash hoarding is rational.

Last year China issued 1 trillion yuan in special bonds to push the official 3% deficit to 3.8%; this year they again issued 1 trillion in special long-dated bonds off-budget; the expected new stimulus package of 2 trillion yuan would approximately match last year's extraordinary measures.

David Tepper's CNBC statement about 'whatever it takes' regarding China stimulus was misinterpreted by markets as a signal of unlimited stimulus, but Tepper was actually discussing only the specific equity purchase and stock buyback facilities, which McCarthy views as having questionable efficacy.

China's local governments have dramatically reduced off-balance-sheet debt issuance as part of government transition toward discipline, but this has created a collapse in local government spending which is currently down 3% year-to-date through August, creating a contractionary fiscal dynamic.

The Chinese banking system has not written down Evergrande's 260 billion dollar loan exposure because doing so would require public acknowledgment of losses; instead, the system is rolling the debt while Evergrande limps along as a zombie company with government implicit backing for ongoing operations.

If China pursues unlimited stimulus (10 trillion yuan), McCarthy expects the RMB to experience significant downward pressure despite any initial rally, because markets would recognize the currency move signals Xi has abandoned his reform agenda and reverted to a broken growth model.

Chinese government authorities likely regret overheating the equity market rally and are concerned about repeating the 2015 bubble experience; they realize the tail (equity market) cannot wag the dog (real economy) and that bubble creation is self-defeating.

China's augmented budget deficit (including central government, local government, and off-balance-sheet spending) is already 11-15% of GDP annually by IMF estimates, meaning the theoretical ceiling for additional fiscal support is limited.

Large Chinese tech companies like Alibaba face headwinds different from US tech giants: their cloud services are underperforming (Alibaba cloud 'sucking'), and unlike US firms, they cannot monetize data because the Chinese state claims ownership and control of data.
