What if Iran's inflation tops 80 percent as deficit monetisation accelerates?

Tehran monetizing its deficit past 80% inflation drives gold-coin hoarding domestically and adds a modest geopolitical-vol bid globally — but the asset read is mostly local. Rhymes with Iran's 2018-19 sanctions-snapback hyperinflation and the 1980 gold blow-off the analogues cite. China's discounted crude purchases are the only FX lifeline; the forward angle is that domestic gold/FX hoarding, not external markets, absorbs the shock, so global spillover stays limited absent a kinetic escalation.

What it would mean

If this plays out, it is a risk-off shock. Tehran monetizes its deficit as waiver relief fades, pushing annual inflation above 80% and triggering fresh gold-coin hoarding. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · Inflation surprise ▲ — which propagate through our causal graph to the markets below.
