本文由Chi等(2023)[1]研究台湾地区针对特定区域实施的贷款价值比(LTV)限制政策对房地产市场的影响。主要发现如下:
自金融危机之后,房屋价格不断上涨,政策制定者打出了很多组合拳,如信贷约束、交易税和资本所得税,来调控房地产价格上涨,并防范银行部门系统性风险。
The most common macroprudential policy instruments: risk weights, reserve requirements, and LTV( loan-to-value) caps imposed to banks.
Main finding: conditioning mortgage credit provision on ex ante local house price growth can cool housing markets, s.t. both real and financial tradeoffs.
These effects are due to a decline in demand rather than credit rationing or lenders steering consumers towards property purchases in unregulated areas carrying higher internal rates of return.信贷配给或者是借款人将购房需求投向不受监管地区
Conforming Loan Limit (CLL):在CLL以下的贷款额度可以被房地美、房利美收购或担保,即CLL上调是放松约束。如果一地房价上涨但CLL不变,是一种信贷条件收紧。
横轴:房价增长率
纵轴:房价比CLL,捕捉到因二级按揭市场监管导致的信贷条件松紧程度,数值为正,则信贷约束越紧。
右上角:房价上升且监管binding,宏观审慎监管;蓝色区域:过度监管
