About the AUD/SBD rate
The AUD/SBD rate is how many SBD one Australian dollar buys. It moves constantly with interest-rate expectations, commodity prices and global risk sentiment - see what moves the rate. Tradergy shows the mid-market reference rate and does not forecast where it’s heading. For the 52-week highs and lows and a daily table, see the AUD/SBD rate history.
Reading the same rate from the other side: the reverse rate, SBD → AUD, is on the receiving Solomon Islands dollar view, and sending Australian dollars to Solomon Islands is covered on the AUD → SBD transfer page. Every AUD pair sits on the convert hub, and to work in more than one currency at once there is the currency converter.
The basket weights the Central Bank of Solomon Islands publishes
Most central banks that run a currency basket keep the recipe to themselves. The Central Bank of Solomon Islands prints it. Its 2025 annual report states that the Solomon Islands dollar is pegged to a weighted basket comprising the US dollar at 78 per cent, the Australian dollar at 16 per cent and the New Zealand dollar at 6 per cent, weights maintained through 2025 after review, with the currency's daily value determined by the movements of those currencies within the basket. For an Australian that produces a mild oddity: roughly a sixth of the thing being bought is, by construction, the currency being sold.
The mechanics sit beside the weights. The Bank calculates the value of the dollar each day against what it calls the intervention currency, currently the US dollar, and is empowered to make discretionary changes to the calculated rate within specified limits - so the basket sets the number and a bounded discretion sits on top of it.
Around that runs a live exchange control regime, administered under an Exchange Control Act dating from 1976 and its 1977 regulations, with a review of the Act begun in 2025 and continuing. All four commercial banks are appointed authorised dealers and may approve payments below a delegated threshold themselves; personal transfers and sustenance above 100,000 dollars need the Bank's approval, trade and services payments above 250,000 must be referred to it, and non-residents need its approval to open an account with a resident dealer at all.
The rule that shapes the supply of foreign currency is on the export side. Proceeds from exports must be repatriated within three months of shipment and sold to a commercial bank - so an exporter's earnings are legally required to come home and be converted.
