How does NAB Business Confidence affect Iron Condor wing width?

NAB Business Confidence has minimal direct impact on SPX iron condor wing width. Focus instead on VIX levels and the ALVH methodology for all sizing decisions.

When NAB Business Confidence prints well below average (under -10), it often coincides with elevated VIX readings above 18-20. In these regimes, widen your iron condor wings by one full strike (typically moving from 10-15 point wings to 15-20 or 20-25 points). Wider wings reduce gamma exposure and give the position more room to breathe during the volatility spikes that usually follow weak confidence data.

Conversely, when NAB Business Confidence is solidly positive (above +5), VIX tends to stay suppressed below 15. Here you can safely tighten wings to 10 points or even 5-7 points on very low VIX days, harvesting higher theta with less capital at risk.

The ALVH framework remains the primary driver: always scale wing width to current VIX percentile and expected holding period. Use NAB data only as a secondary sentiment filter to confirm whether the prevailing VIX level is likely to remain stable or expand. Never adjust wings solely on the confidence number. Let implied volatility dictate the final wing size.
