&gt; Excessive saving can be a problem, which the Fed is trying to address.<p>And maybe trying to address in exactly the wrong way.<p>Let&#x27;s say I&#x27;m trying to save for retirement.  If, during retirement, I&#x27;m going to be able to earn 4% return, I need some amount.  If I&#x27;m going to earn 0.1%, I need a lot more, so I&#x27;d better save a lot more now.  And if interest rates go negative, then I have to save even <i>more</i>...<p>So this approach may not actually lead to decreased saving.
