〔Overnight Brief〕Hungary Floats Above-1% Wealth Tax to Close 7.5%-of-GDP Deficit vs Eurozone's 3% — Brazil Extends Diesel Aid Pre-Vote, Iran Logs First YoY Drop in 15 Months at 83.8%

0. Overnight Arc

EM fiscal pressure ran on two tracks: Hungary moved to tighten at the top with a wealth tax aimed at super-rich rates above 1%, while Brazil loosened pre-vote with a 30-day diesel subsidy extension ^[1][2]. Against that, Iran logged its first YoY inflation drop in 15 months at 83.8% from 84.4%, even as US sanctions and a maritime blockade remain in force ^[3]. Net: a eurozone-anchored sovereign tightening into an election-cycle stimulus, with a sanctions-economy base-effect break underneath ^[1][2][3].

1. Hungary — Wealth Tax Floats Higher

• **[NEW] Orban signals above-1% rate for super-rich:** assets above 1 billion forints (~$3.1M) face the headline 1% rate; the 'super-rich' bracket is expected above that floor ^[1]. Implementation target: by January 2027 ^[1].
• **[NEW] Deficit backdrop:** 2026 deficit may hit 7.5% of GDP vs the eurozone's 3% rule, with pressure to cut by 2030 ^[1]. Announced at a Saturday rally in Szolnok ^[1].
• **Source quality control:** the super-rich above-1% framing is a single-source statement from the PM at a political rally; treat the headline 1% rate as confirmed, the 'higher' rate as signal not yet codified ^[1].

2. Brazil — Diesel Subsidy Extends Into Vote

• **[NEW] Decree extends 2.12 real/liter (~$0.41) diesel subsidy** for at least 30 days from the May 30 emergency-measure baseline; subsidy amount unchanged ^[2].
• **[NEW] Election window:** first round October 4 ^[2]. President Lula announced further fuel-tax cuts this month to shield consumers from US-Iran war oil-price spikes; gasoline and ethanol taxes also cut ^[2].
• **Mechanism:** the package is sized as a price buffer rather than a fiscal expansion, but it locks the Treasury into the diesel spread into the runoff period ^[2].

3. Iran — First YoY Inflation Drop in 15 Months

• **[NEW] September YoY 83.8%,** down from 84.4% in August, per CBI Governor Abdolnaser Hemmati via Tasnim ^[3]. Officials framed the small print as a directional break, not a trend ^[3].
• **[ONGOING] US 'Operation Economic Outcast':** new sanctions plus a maritime blockade of Iranian ports remain in place ^[3].
• **Read:** the drop is the first YoY decline in 15 months, but at 83.8% the level still anchors any disinflation story firmly in crisis territory ^[3].

4. EM Debt, Trade and Development

• **[NEW] Bangladesh debut sovereign bond:** up to $1 billion targeted; pricing window unconfirmed ^[4].
• **[NEW] Canada-Vietnam:** PM Mark Carney called Vietnam Canada's largest ASEAN trade partner; partnership deepened this week to open access for Canadian firms in one of the world's fastest-growing consumer markets ^[5].
• **[NEW] NDB (Shanghai-headquartered) to anchor an anti-hunger fund** by year-end guaranteeing cheap loans for poor families in Africa and Latin America, per Brazil's Social Development Minister Wellington Dias on the UNGA sidelines; would be the NDB's first financial commitment to Brazil's alliance, an initiative sidelined by the US G20 presidency ^[6]. Mentioned as background — multilateral development, not China-macro.
• **[ONGOING] IMF staff visit to Gabon concluded**; no program details in the packet ^[7].

5. What Decides Next

Hungary's draft text and the effective top-bracket rate above 1% ^[1]; Brazil's October 4 first round and whether the diesel subsidy is renewed into a runoff ^[2]; Bangladesh's pricing and book size once the debut is launched ^[4]; and whether Iran's October print holds the 83.8% YoY reading under live sanctions and blockade ^[3].
