摘要:Nonparametric test statistics document the nonlinear cointegration between the Malaysian lending and deposit rates. Empiri cal investigation further reveals that their spread asymmetrically adjusted to the threshold faster when the deposit rate fell relative to the lending rate than when the deposit rate moved in the opposite direction. These findings may be attributable to robust Islamic and conventional financial systems that operate parallel to each other. These empirical findings also suggest that Malaysian lending institutions in the conventional segment of the economy do not exhibit predatory pricing behavior. Furthermore,empirical results indicated that the Malaysian lending rate and deposit rate adjustments affected each other’s movements. As to the long-run behavior of lending and deposit rates,the empirical findings indicated that while the Malaysian lending rate responded to both,the deposit rate responded to neither the expansionary monetary policy,which widens the lending-deposit rate spread;nor the contractionary policy,which narrows the spread in the short run.
