The RBA's interest rate decision directly determines the yield curve for the Australian Dollar, thus having a very high direct impact on the AUD exchange rate (AUD/USD). An unexpected hike or cut would also significantly impact the Australian benchmark index (ASX 200). While the impact on Gold or global markets is relatively minor, as a G10 central bank, its decisions still carry some signaling value.

April 29, 2026 - May 2, 2026, the price of the 'Increase' option surged from 84.5c to 96c before settling around 93.5c, while 'No Change' dropped from 16.5c to 1.75c before rebounding to around 7c. The reason is that as the May 5 meeting approaches, the market further priced in and fine-tuned the probability of a rate hike in the final days. April 28, 2026 - April 28, 2026, the price of the 'Increase' option crashed from 87.5c to 47c, while 'No Change' spiked from 12.5c to 50c and 'Decrease' surged from 0.25c to 49.5c, before all rapidly reverting to previous levels. The reason implies a massive erroneous trade (fat finger) or a brief liquidity gap that caused instantaneous price distortion. April 15, 2026 - April 18, 2026, the price of the 'Increase' option surged from 60.5c to 75.5c, while 'No Change' plummeted from 39.5c to 22.5c. The reason is the market further pricing in the rate hike expectation as the May RBA meeting approaches, reinforcing the earlier institutional consensus. April 4, 2026 - April 5, 2026, the price of the 'Increase' option surged from 59c to 74.5c, while the 'No Change' option plummeted from 40c to 23c. The reason is the market further pricing in the expected May rate hike, reinforced by solid institutional consensus and possibly new macroeconomic data. March 15, 2026 - March 21, 2026, the price of the 'Increase' option steadily recovered from 55c to 59.5c, while 'No Change' adjusted from 35.5c to 38c. The reason is the gradual restoration of market liquidity, with investors repricing based on major banks' hike forecasts, correcting the previous panic selling. March 5, 2026 - March 6, 2026, the price of the 'Increase' option crashed from ~65.5c to 34.5c before rapidly rebounding to 63.5c; simultaneously, 'Decrease' spiked from <1c to 25.8c before retracting. The reason implies a market panic reaction to sudden economic data or a single large erroneous trade (fat finger/liquidity gap), briefly pricing in a surge in cut/recession probability, which the market quickly corrected. Feb 9, 2026 - Feb 10, 2026, the price of the 'Increase' option surged from 51c to 61.5c. The reason is that following the RBA's surprise hike in early February, CBA and Westpac revised their forecasts to join NAB in predicting another hike in May.
