Predicted for 31. December 2026
·
Based on: Speculative
The S&P 500 stood at 7,621.76 on September 18, 2026. The 8,000 mark requires a further +5.0% gain to year-end (≈ 3.5 months). Headwinds: The open Cassandra prediction of a Fed rate hike to 4.00–4.25% in October 2026 raises the discount rate for growth stocks. Tailwinds: Q4 seasonality (S&P 500 historically +2–3% on average), robust Q3 2026 earnings expectations (Meta revenue >$63.5B, Microsoft >$82B per existing predictions). VIX-implied volatility of ~17–19 yields a 1-standard-deviation range of ~8% over 3.5 months; 8,000 sits just under half a standard deviation above the current level. No Polymarket market for S&P 500 year-end 2026 is known; fair assessment: ~48%.

The IBEX 35 closed at 19,384.70 points on September 18, 2026 (+0.32%). The 19,100 threshold is 1.5% below the current level. With historical IBEX daily volatility of ~0.9–1.2% and two trading days remaining until Monday September 22, the 2-day standard deviation is approximately 1.6–1.7%, placing the threshold ~0.9 standard deviations below current levels — implying ~82% probability of remaining above. Macro support: SNB expected to hold rates at 0.00% (consensus: 40/41 economists, Reuters poll); EUR/USD stable at 1.1461; no critical ECB decisions within the window. No existing Cassandra prediction explicitly covers the IBEX 35.

The Bank of Japan raised its policy rate by 25bp to 1.25% today as expected – highest since 1995 (Bloomberg, Sept 18, 2026). Paradoxically, the yen weakened: USD/JPY rose to ~157.33 (FXLeaders/Bloomberg) as a gradual BoJ approach and two dissenting board members disappointed markets. EUR/USD simultaneously sits at 1.1461 (TradingEconomics), putting EUR/JPY at ~180.2. For EUR/JPY to close below 179.00 on September 19 would require a drop of more than 0.7% – unlikely while the yen carry trade remains favored and the Fed stays hawkish (funds rate 3.75–4.00% since Sept 16).

WTI crude oil is at $103.05/bbl on September 18, 2026 (CNBC), Brent at $104.64. Supportive factors: ongoing Houthi attacks on Red Sea/Gulf of Aden shipping (NPR/MARAD, Sept 18), US-CENTCOM activity in the Persian Gulf, and OPEC+ production discipline. For WTI to fall below $101 by September 22 would require a drop of more than 2% in four trading days. Headwinds include Fed hikes to 3.75–4.00% (demand risk) and the BoJ rate hike. However, the geopolitical supply-disruption premium dominates. The existing open prediction for WTI covers October 31, not September 22.
