RBA's Debelle: Theoretically, central bank can lower policy rate if needed

More comments are flowing in from the RBA Deputy Governor Debelle, as he continues to speak at the American Chamber of Commerce in Australia (AmCham) with Adelaide Business School event in Adelaide.

Theoretically, central bank can lower policy rate if needed.

Does not expect to have to introduce QE.

Still expects decent growth in the economy.

We are in uncharted territory with downturn in house prices.

But so far, housing has unwound in a reasonably orderly way.
