South Africa CPI YoY Forecast 2026
Quantitative analysis from 284 observations of South Africa CPI YoY history, joined to four universal macro regime classifications. Numbers are computed, not narrated.
Performance by Window[02]
| WINDOW | N | ANN RET | ANN VOL | RET/VOL | HIT % | TOTAL |
|---|---|---|---|---|---|---|
| 1Y | 12 | -46.62% | 31.20% | -1.49 | 27.3% | -43.78% |
| 3Y | 36 | -18.56% | 29.16% | -0.64 | 37.1% | -45.04% |

| All | 284 | -2.99% | 106.80% | -0.03 | 45.9% | -51.11% |
Annualized total return = (1 + total)^(1/years) - 1. Ret/Vol is the annualized return divided by annualized volatility (Sharpe-equivalent without risk-free subtraction). Hit % = pct of single periods that were positive.

Forward returns are forward-looking from each historical observation in the bucket; +252d corresponds to one trading year. Buckets with fewer than 5 forward-return observations are reported as n/a. These are conditional historical averages, not forecasts.
Lead-Lag Relationships[05]
For each universally-recognised leading indicator, the lag at which the daily-return correlation peaks. Positive lag means the anchor leads South Africa CPI YoY; negative means it lags.

| HY OAS Spread | Credit risk leader | +1d | -0.361 | -0.068 | coincident |
| Trade-Weighted Dollar | FX driver | -48d | 0.329 | -0.007 | lags target by 48d |
| 10Y-2Y Yield Spread | Recession leader | -32d | 0.295 | 0.035 | lags target by 32d |
| Baa-10Y Spread | Credit risk (slow) | -48d | 0.259 | 0.006 | lags target by 48d |
| Copper | Global growth proxy | -48d | -0.234 | -0.039 | lags target by 48d |

| VIX | Volatility leader | +56d | -0.176 | 0.060 | leads target by 56d |
| 10Y Treasury Yield | Discount-rate driver | -50d | -0.161 | 0.009 | lags target by 50d |
Pearson correlation of daily returns over up to 25 years of overlapping history, searched across a ±60-day lag grid. Indicators classified as “weak” don't have meaningful predictive power at daily resolution; many of these (yield curve, NFCI, sentiment) lead at monthly/quarterly horizons instead.

Frequently Asked Questions
What factors could push South Africa CPI YoY higher?▾
The primary drivers that tend to lift South Africa CPI YoY depend on the current macro regime. South Africa consumer price index, year-on-year change. Convex tracks these drivers live across the International Inflation category and flags when multiple forces align in the same direction. See the "Key Drivers & Risks" section on this page for the current list, and check the regime dashboard for how the macro backdrop is currently tilted.
What factors could push South Africa CPI YoY lower?▾
The same transmission channels that drive South Africa CPI YoY higher operate in reverse when conditions flip. The risk drivers listed above map directly to scenarios that, if triggered, would pull this metric in the opposite direction. Convex aggregates these into a scenario-weighted probability distribution rather than a point forecast, so the magnitude depends on which scenarios activate.
Where does consensus see South Africa CPI YoY heading?▾
Rather than publish a point target that goes stale the day after release, Convex assembles consensus from the macro regime classification, active scenario probabilities, and historical base rates. Point forecasts from banks and strategists are worth reading for context, but they typically cluster around the consensus and miss the tail events that actually move markets. The scenario-weighted approach here captures that tail risk explicitly.
What is the historical range for South Africa CPI YoY?▾
Historical ranges for South Africa CPI YoY vary dramatically by regime. A level that is extreme in Goldilocks can be routine in Stagflation, and vice versa. The Historical Volatility section on this page describes the typical range and regime-specific behavior. For the full multi-decade history, visit the South Africa CPI YoY chart page, which includes selectable time ranges up to five years and downloadable data.
How often is the South Africa CPI YoY forecast updated?▾
This forecast page recalculates whenever the underlying data or regime classification changes, typically within hours of new data releases. The scenario probabilities refresh daily as the macro state is regenerated. Specific drivers listed on this page reflect the current state of the Convex regime engine, not static historical assumptions.
Is this forecast actionable for trading?▾
Convex forecasts are informational and educational. They describe probability distributions and regime-conditional paths rather than specific entry and exit levels. Traders and portfolio managers use them alongside other inputs including position sizing rules, risk management, and their own conviction calibration. They are not investment advice.
