Yes, but the World's Central Banks can only control the Short Term Cash Rates. The Long Term Interest Rates which impact upon Mortgage Rates are impacted by the Bond Markets and the Central Banks have no control over Long Term Interest Rates.
Long Term Interest Rates need to normalise as Pension Funds around the World will collapse otherwise and Savers need to be rewarded. That is how the Capitalist System should work. Capital formation is the key to Investment. Having Short Term rates at 5,000 year lows for an extended period has only encouraged speculation. I agree, QE has been an absolute disaster !!
Long Term Rates are on the way up and could easily increase very quickly over the next year or two. When that happens Governments are in Big Trouble, along with the over indebted Residential Property Market, and as Government Deficits explode with interest payments on Sovereign Debt taking more and more of the tax receipts meant for basic Services, taxes will need to rise to compensate, further crimping the Economy and the spending power of Tax Payers.
Then, once the population at large loses confidence in Government (who over promise and under deliver), that is when Gold, Silver and other Precious Commodities will "hit the roof" and that is when the DCNs of this World will "hit the roof" even more............
Hang in there DCN Investors as we are on a WINNER !! (along with many, many other quality Gold Producers)
