With Janet Yellen increasing the US Fed Rates to 1 – 1.25% and Graeme Wheeler keeping the OCR at 1.75% it is anticipated that the US Fed Rate will eventually become higher than the OCR. What impact might this have on the New Zealand dollar?
With higher rates (or expected higher rates) in the US money flows will be attracted into the US with higher interest rate returns. This is referred to as ‘Hot Money’ and for international investors there are significant amounts of money to be made.
A higher interest rate in the US would mean a higher return from saving in a US bank. Therefore, New Zealand investors may sell NZ dollars and buy US dollars so that they can gain more interest from their savings. This increased demand for US dollars will push up the value of the US dollar against the NZ dollar.
However it is not just interest rates that influence Hot Money. In 2011the Swiss Franc appreciated on the back off the turmoil in the Eurozone as investors saw the currency as a safe haven. The NZ dollar and the AUS dollar appreciated for similar reasons post the Global Financial Crisis.
Problems of hot money flows
Hot money flows can be destabilising. A rapid rise in the currency can harm a countries with exports become more expensive and imports becoming cheaper. However the latter might be favorable depending on the import content.
Hot money flows can create excess liquidity fuelling a future asset boom and creating more long-term problems.
