Predicted for 17. September 2026
·
Based on: Historical Cycle
The S&P 500 was at 7,629 on 14 September 2026 (Trading Economics), already close to the threshold. On 16 September 2026 (FOMC decision day), an open Cassandra forecast sees a close below 7,600 – consistent with moderate sell-the-rumour dynamics before the decision. The 25 bp Fed-funds hike to 3.75–4.00% was priced in at 91% per Kalshi (KXFEDDECISION-26SEP) and Yahoo Finance as of 16 September 2026. Historically US equity markets recover 0.3–0.6% on average the day after a fully anticipated rate hike ('buy the news'). VIX stood at 17.10–17.68 on 15–16 September; a post-decision VIX decline supports recovery above 7,600. No Polymarket market for an exact S&P level on 17 September available.

USD/JPY was at 154.06–155.17 on September 14–15, 2026. The Bank of Japan is expected to hike +25bp to 1.25% on September 18 (open prediction on this platform). A BoJ hike structurally strengthens the yen. For reference, the unexpected August 2024 BoJ hike pushed USD/JPY from 155 to 142 in 3 days (approx. −8%). Since the current hike is better priced-in, the effect is more moderate; a decline to below 153.00 (approx. −1.3% from 154.5) remains plausible. The simultaneous September 16 Fed hike supports USD in the opposite direction but should be fully priced in.

The DAX stood at approximately 25,440–25,568 points on September 15, 2026. The FOMC decision falls on September 16 at 20:00 CET – after DAX market close – making September 17 the first European reaction day. CME FedWatch and Polymarket assign ~91% probability to a 25bp hike to 3.75–4.00%, treating it as fully priced in. A close below 25,200 points on September 17 would require unexpectedly hawkish Fed communication or a negative global risk event. The 10-year US Treasury yield stood at 5.02% on September 14 – market stress already partially absorbed. Base case: modest consolidation, no sharp selloff.

Polymarket implies ~48–53% (normalized) for a year-end close above 65,000: the raw sum of categories ≥65,000 (65k–70k: 24%, 70k–75k: 16%, 75k–80k: 8%, 80k–85k: 6%, >85k: 8%) totals 62%, normalizing to ~50%. The Nikkei traded at ~63,835 on September 15, 2026, requiring a ~1.9% rally by year-end. Headwinds: BoJ hikes to 1.25% on September 18, strengthening the yen and pressuring export-heavy index components; FOMC rate hike squeezes global liquidity. Tailwinds: BofA ML raised its Nikkei year-end target to 76,000; structural corporate reforms and AI demand underpin Japanese equities.
