What if sticky inflation forces surprise back-to-back RBA hikes?

Back-to-back emergency RBA hikes after a dovish hold whipsaw AUD and front-end rates: the read is higher reals and a risk-off duration hit, with AUD spiking and rate-sensitive tech sold. Rhymes with the 2010-11 RBA tightening cycle and the broader 2022 hawkish-surprise complex that punished long-duration equities. Australia exports iron ore/LNG to China; sticky domestic inflation forces the RBA's hand independent of the terms-of-trade. Forward: a housing-leveraged economy makes each surprise hike more destabilizing than the Fed's.

What it would mean

If this plays out, it is a risk-off shock. After a dovish hold, sticky Australian inflation forces back-to-back emergency RBA hikes, whipsawing AUD and rates traders. The trigger decomposes into signed root‑shocks — Fed policy path ▲ · Inflation surprise ▲ — which propagate through our causal graph to the markets below.
