〔Overnight Brief〕BOJ October Hike Path Compresses on Ex-Official's 20-30% Consecutive-Move Call — Yet Korea Opens 24-Hour Won at Multi-Year Lows, and Japan Braces for 3,033 October Food Hikes

0. Weekly Arc

BOJ tightening odds firmed over the weekend: former executive director Kazuo Momma tagged 20-30% probability on a back-to-back October hike, well ahead of most economist timelines ^[1]. Korea pushed the other side of the rate cycle — a 24-hour won international settlement pilot launched September 21 at multi-decade currency lows, a move the source frames as carrying "significant risks" alongside its strategic ambition ^[2]. Japan's domestic price backdrop stays hot: 3,033 food items set to rise in October, with the full-year tally tracking toward ~20,000 ^[3]. The week ahead is dense: RBA decision Tuesday, ECB President Lagarde's quarterly testimony Monday, and a full euro-area, UK and US data slate running through midweek ^[4]. Falsifiable test for the BOJ path: the October policy meeting itself ^[1].

1. BOJ Path

• **[NEW] Former BOJ executive director Kazuo Momma:** told media the base case is roughly one hike every three months, but assessed a 20-30% probability of a consecutive move at the October policy meeting — earlier than most economist timelines ^[1]. "The probability is around 20% to 30%," Momma said ^[1]. The signal follows the September hike; the open question is whether the board compresses the cadence ^[1].

2. Korea: Won Internationalization

• **[NEW] Bank of Korea launched 24-hour won international settlement pilot on September 21** — the first always-on payment and settlement network excluding weekends and holidays ^[2]. The system is built atop the government's earlier 24-hour FX market launch and the relaxation of restrictions on foreign-investor won trading, extending the unwind of a three-decade FX regime ^[2].
• **[ESCALATED] Risk framing:** the won trades at historic lows as the capital account opens; the source flags the move as carrying "significant risks" alongside the strategic ambition ^[2]. The 1997 Asian financial crisis is invoked as the cautionary template: the won collapsed from 844/USD at the start of that year to 2,060/USD by year-end, with $63.8bn net external debt against only $8.9bn of usable reserves, before an IMF rescue ^[2].

3. Japan Domestic Prices

• **[NEW] Teikoku Databank survey of 195 food and beverage producers:** 3,033 food items are set to rise in October — including frozen foods (+5-8%), snacks (+3-17%) and beverages (+5-21%) ^[3]. The full-year tally is tracking toward ~20,000 items ^[3]. Source chain: single Xinhua wire via 10jqka relay ^[3].
