The Washington H. Soul Pattinson and Co. Ltd (ASX: SOL) share price fell by 8.4% in June 2022. That compares to a decline of 8.9% for the S&P/ASX 200 Index (ASX: XJO).
So what contributed to such a tough run?
Last month, one of the biggest headline-grabbers was the Reserve Bank of Australia (RBA) increasing the interest rate by 50 basis points, or 0.5%.
The RBA wants to get on top of inflation and slow it down. However, the size of the increase was more than some in the market expected.
The RBA is currently expecting inflation to peak at around 7% in the quarter for the three months to 31 December 2022. Interest rates are also tipped to go higher in the coming months.
Interest rates can have a significant impact on valuation. In theory, higher interest rates are meant to pull down the valuation of assets.
