I don't see how the RBA can say they are targeting 2-3% inflation without raising rates. Though I won't be surprised if they use the next meeting to basically say next time its coming so it's not a surprise when it happens...
Interest rates don't really affect my investments. I assume such external variables are within the realm possibilities and out of my control. If the business is going to be taken out by change in interest rates (say 2% or less) why am I investing in such a fragile business? Everyone is on the same playing field, it's not like it won't affect the competitor's business in a similar way. I only invest in businesses where my expected return is above 15% pa otherwise it is a no go. From my point of view, the effect of interest rates with regards to my expected return should be a rounding error, I don't believe I can be precise enough that it matters.
In saying all that I do actually own a business in the US that is directly affected by the Feds interest rates. Stone X (Nasdaq ticker SNEX), it's a financial services business. It makes some profit from the float of client funds. If rates were to change by 1% this could change profitability by about 20%. However, they are a growing business so can offset any reductions in interest rate related profits by increasing client funds compared to slower growing competitors. Even given the large profitability affect, the potential for long term growth of Stone X is far more important to me.
I guess it is businesses similar to Stone X that have a large cash float to profit from that are the biggest winners from interest rate rises.
