Richmond聯儲銀行嘅 Thomas A. Lubik同Christian Matthes,係該行嘅網誌分享佢地關於美國十年來再遇零息下限(Zero Lower Bound)機率嘅研究

兩位利用VAR模型綜合1961年至2018年嘅美國經濟數據,並製作出經濟預測模型,再用呢個模型多次模擬未來十年美國經濟走向,再計算係呢啲模擬情況中聯儲局要減息去到零嘅情況出現次數,以之作為零息下限出現機率。

以下就係運算結果,藍綫係各年分別會錄得零息嘅機率,可以見到機率會一直上升,至2025年左右見頂,去到15%嘅出現機率水平。

紅綫則係累積機率,即係係該日或以前美國就已經試過要減息到零嘅機會率。可以見到模型推算係2028年前美國會出現零息嘅機會,係大約25%。

The likelihood of returning to near-zero interest rates is relevant to policymakers in considering the path of future interest rates. At the zero lower bound, the Fed can no longer lower rates and thus can respond to a contraction only through alternative policy measures, such as quantitative easing.
