The Ten Year is yielding about 1.63%. When you subtract the CPI of 2.6% (March number) the real yield on the ten is minus .88%.  The price of lumber has risen 30% since the March number. Many other items like Aluminum, you name it are rising sharply. When the April CPI number comes out on May 12 my back of the envelope calculation for CPI is 3.6%! That would make the real yield on the Ten Year Minus 1.88%. That is Rocket Fuel for anything Gold.
