Predicted for 20. July 2026
·
Based on: Speculative
On July 20, 2026, Japanese voters elect the House of Councillors (Upper House). LDP/Komeito hold a slim upper-house coalition majority. CSIS analysis diagnoses 'prolonged instability' following the LDP's lower-house majority loss in October 2024. Despite PM Takaichi's landslide Lower House win in February 2026 (315/465 seats), headwinds remain: opposition parties (CDP, Nippon Ishin, Sanseito) exploit the ongoing LDP funds scandal (>50% of respondents cite it, Kyodo poll). No direct Polymarket/Kalshi market found; structural assessment: ~68%.

Polymarket assigns 91% probability to 'no change' at the ECB's July 23 meeting; ECB-Watch.eu confirms ~90% implied hold probability. The ECB raised the deposit rate to 2.25% on June 11, 2026 (first hike since 2023, responding to the Iran oil shock). July is not a projections meeting — updated ECB staff forecasts come only in September. An existing Cassandra forecast already predicts a further hike to 2.50% at the September meeting. Polymarket sees 91% for unchanged rate.

The Merz government (CDU/CSU–SPD, since March 2025) made Bundeswehr modernization a top priority. Defense Minister Pistorius developed a selective service model (Swedish-style) in 2025. The coalition agreement includes mandatory service reform options. A Bundestag vote by September 30 requires completion of cabinet draft, all readings, and potential Bundesrat involvement. Obstacle: major German legislation typically takes 9-18 months. No Metaculus/Polymarket market. Estimated P: ~29%.
