Its not opinion ,its fact!!
Since central banks have followed a policy of quantitate easing and loose monetary policy asset prices (shares and property) have sky rocketed. Simply as cash gives almost zero returns investors put their cash elsewhere. This is illustrated by almost zero inflation , very low wage inflation yet house prices rose 10% last year and the FTSE 100 is at an all time high!
The question is what happens when these polices end? Asset prices will fall as investors move back to cash. This is why there may be a reluctance to raise interest rates.

"“Quantitative easing, whereby we bought huge quantities of Treasury bonds, made it very cheap for the government to borrow. It obscured the cost of rising public debt and made it possible for the government to put off making tough budgetary choices. It also probably deterred risk-taking by corporate America. Growth has been hard to sustain even with this aggressively easy policy. The longer we persist with this stance and keep rates where they are, the more likely it is that we are perpetuating an illusion, an economy still founded on debt and artificially maintained asset prices.
“This worries us. We have great economic brains, including, ahem, my own; but frankly, we don’t know what to do. No central bank has been in this territory before and we have an obligation to the American people and to our economic partners not to screw it up.
“For that reason, I am committing to no interest rate increase at all in 2015. There is a danger, and it’s been referred to by the Bank of International Settlements, that, in the absence of consumer prices inflation, all we are doing is inflating an asset-price bubble. It’s a theoretical problem, though. If we raise rates now before growth has been properly established, we may get a financial crisis anywhere and amid economic stagnation. I’m not going to risk that. We went into this unprecedented monetary stimulus quickly, six years ago, to stabilise the financial system. We have no responsible option but to come out of it only gradually."
