〔Day Digest〕French 10Y OAT Hits ~4.95% as IMF Tags Disorderly Sovereign Yields Top Tail Risk; Developed-Economy Deficits Hit 5.2%, Highest Since 2021 — BoJ Leans Against October Consecutive Hike

0. Daily Arc

The IMF-World Bank annual meetings in Bangkok set the macro frame: developed-economy deficits at 5.2% of GDP — the highest since 2021 — with the IMF explicitly warning that sovereign yield spikes are a top tail risk ^[1][2]. France became the live stress test, the 10-year OAT spiking to ~4.95%, a 2002 high, and the OAT-Bund spread breaching 150bp for the first time since late 2011 ^[3]. Yet the front end stayed defensive: the BoJ leans against an October consecutive hike, and Japan's 10Y eased 1.5bp to 2.995% ^[4][5]. Net: a long-end fiscal/supply story against an anchored short-end — France is the print that decides whether the stress stays disorderly.

1. IMF in Bangkok: The Fiscal Warning

• **[NEW] IMF WEO:** Global growth 3.1% in 2026 and 3.4% in 2027; global inflation 4.7% in 2026 easing to 4.1% in 2027 (cumulative +0.7pp upgrade), driven by energy and food ^[6]. Developed-economy net borrowing at 5.2% of GDP is the highest since 2021, with US 2026 net borrowing projected at 8.5% of GDP versus 7.1% in 2025 ^[1].
• **[NEW] IMF GFSR:** Three live risks — an AI asset correction from weakening AI investment/returns and rising leverage; a sovereign yield spike on inflation relapse or fiscal fears; and rising cyber threats from digital finance ^[2][7].
• **[NEW] BoA Global Fund Manager Survey:** Biggest tail risk is a disorderly bond yield rise, second is an AI bubble; investors say a 5.9% US 10Y yield would trigger rotation from equities to bonds; optimism at the lowest since June; net 1% expect higher long rates ^[8].
• **[NEW] IMF officials:** Market participants are pricing fiscal risks and uncertainty "as they should," and a reassessment of risks could prompt countries to get fiscal houses in order ^[9][10].
• **[NEW] The Guardian summary:** The IMF WEO warns the global economy "could soon test the limits of resilience," with state oil stocks low and budgets overstretched; the UK 2026 growth forecast was upgraded ^[11].

2. Europe: France as the Flashpoint

• **[ESCALATED] France:** 10Y OAT spiked to ~4.95% — a 2002 high — after the October 1 budget/issuance plan; the OAT-Bund spread breached 150bp for the first time since late 2011 ^[3]. EUR/USD fell to 1.1161 on October 5, a 17-month low, while US Treasuries saw safe-haven flows the same day ^[3].
• **[NEW] Drivers (China Securities' Qian Wei team):** Global rate backdrop, France-specific fiscal/political risk, and crowded positioning ^[3]. The same note frames the ECB as tilting toward a "cautious hike bias" — that is the third-party characterization, not an ECB statement ^[3].
• **[NEW] Blackstone Group President Jon Gray:** Fiscal risk is more pressing in France, the UK and continental Europe than in the US, because growth is lower and deficits are large; the US is being temporarily cushioned by the AI boom ^[12].
• **[ONGOING] Energy channel:** Energy inflation is worsening Europe's fiscal difficulties, per Xinhua ^[13].
• **Source-quality control:** the "ECB cautious hike" framing comes from a single Chinese-bank research note; the ECB itself has not been quoted in this packet ^[3].

3. Japan: BoJ Holds the Line

• **[NEW] BoJ:** Leans against an October consecutive hike ^[4].
• **[NEW] JGBs:** 10Y down 1.5bp to 2.995% ^[5].
• **[NEW] Japan September PPI:** +6.8% y/y, index 135.7 (2020=100) ^[14].
• **[NEW] IMF WEO:** Expects the BoJ to gradually raise rates toward neutral ^[15].
• **Tension:** The IMF expects gradual normalization ^[15] while the wire report says the BoJ leans against back-to-back hikes ^[4]. Print both — the wire is the newer signal, the IMF is the longer-run frame.

4. Emerging Markets and Asia

• **[NEW] India 10Y:** Down 5bp to 7.34% ^[16].
• **[NEW] Kazakhstan:** Jan-Sep oil output down 8.3% to 69.4 million tonnes ^[17].
• **[NEW] Korea:** KOSPI foreign outflows YTD hit 992.5 billion yuan, with a fifth consecutive losing session, on AI financing concerns and oil-driven risk-off ^[18].
• **[NEW] Thailand:** Considering a ~1,000-baht (~$30) departure tax on Thai and foreign travelers, plus a 450-baht foreign air-arrival fee ^[19].
• **[NEW] Greece:** Heating oil subsidy to rise 30% this year, per the Greek finance minister ^[20].
• **[NEW] Bank of England MPC member Greene:** The latest IMF UK forecast "did not come as a surprise" ^[21].

5. Trade, Sourcing and What Decides Next

• **[NEW] WTO Chief Economist Robert Staiger:** AI-enabled goods trade grew 67% in H1 2026 and contributed 47% of H1 2026 goods-trade growth despite holding under 15% share; 2026 tariff shifts are less disruptive than AI or the Middle East crisis ^[22].
• **[NEW] BNP Paribas Group Chief Economist Isabelle Mateos y Lago:** The global economy remains resilient, but is strained by rising interest rates and energy shocks ^[23].
• **[NEW] IMF two-track split:** Geopolitics and technology are widening the divergence between buffered tech-exporters and import-burdened economies ^[24].
• **Falsifiable test:** Whether the OAT-Bund spread closes above 150bp; whether the 10Y OAT closes above ~4.95%; the BoJ's October decision; and any fresh euro area fiscal delivery ^[3][4].
• **Source-quality control:** The "ECB cautious hike" framing is third-party, not on-the-record ECB ^[3]. IMF and BoA figures here come from press wires, not the underlying tables; the Xinhua and Guardian items are single-source characterizations of the IMF picture ^{[1][8][13][11]}.
