The Australian and New Zealand dollars found their footing on Monday after a rough week that saw both currencies slide to multi-month lows. The bounce came as traders weighed a stronger US dollar, growing expectations of a Federal Reserve rate hike, and a nail-biting election count in New Zealand.
For everyday investors, currency moves like these matter because they affect the value of international investments, the cost of imported goods, and the returns on overseas assets. When the US dollar strengthens, it can ripple through global markets, hitting currencies like the Aussie and Kiwi particularly hard.
Why the currencies wobbled
The recent slide in the Australian and New Zealand dollars was largely driven by the greenback's surge. According to Reuters, the US dollar posted its biggest jump in nearly five months after stronger-than-expected US jobs data and hawkish comments from Federal Reserve officials. That strength reflects growing conviction that the Fed will raise interest rates again in December, with markets now pricing an 81% chance of a hike.
Higher US interest rates tend to pull money toward dollar-denominated assets, as investors seek better returns. That dynamic puts pressure on other currencies, especially those from smaller, trade-dependent economies like Australia and New Zealand. When global investors get nervous, they often retreat to the safety of the US dollar, leaving riskier currencies like the Aussie and Kiwi in the lurch.
This is a familiar pattern for these two currencies, which are often seen as barometers of global risk appetite. Both are closely tied to commodity prices and Asian demand, making them sensitive to shifts in the global economic outlook.
New Zealand's election adds a twist
While the Aussie dollar's fate is largely tied to global factors, the Kiwi has its own local catalyst: the final shape of New Zealand's next government. The country's general election was held in October, but the result is still not final, with official results due on November 27th.
Analyst Josh Williamson at Citi, a global bank, said there's a 55% chance that Prime Minister Christopher Luxon's center-right coalition retains power. Citi argues that outcome would likely mean a smaller fiscal footprint and keep the Reserve Bank of New Zealand focused on a single inflation mandate.
Why does this matter for the currency? Expectations about government spending affect how many bonds a country issues, which in turn moves bond yields—the interest the government pays to borrow. Those yield shifts can feed into the New Zealand dollar when traders compare returns across countries.
If investors think the next government will borrow less, they may expect less bond supply, which can lower longer-term yields and change the NZD's appeal versus other “carry” currencies that benefit from higher yields. Flip the logic, and a shift toward more spending, or a different view of how tough the central bank will be on inflation, can push yields and the currency the other way.
What it means for investors
For investors, the key takeaway is that the New Zealand dollar may stay unusually headline-sensitive until the official tally on November 27th. Into that date, the Kiwi may trade less like a simple “US dollar up, NZD down” story and more like a read on New Zealand's fiscal and rate outlook.
That means if you hold New Zealand assets—whether bonds, stocks, or property—currency swings could add an extra layer of volatility to your returns. Similarly, if you're investing in Australian assets, the Aussie dollar's moves against the greenback will influence the value of your holdings when converted back to US dollars.
For those with a globally diversified portfolio, currency fluctuations are part of the package. As we've noted before, a single global ETF can simplify investing across world markets, but it doesn't eliminate currency risk. Understanding how currencies move can help you make more informed decisions about your international exposure.
Looking ahead, investors will be watching the Fed's next move, as well as any developments in New Zealand's political landscape. The US dollar's strength is likely to remain a key driver for both the Aussie and Kiwi, but the Kiwi's fate is also tied to the outcome of the election count.
As always, it's important to remember that currency markets can be unpredictable. While the current bounce offers some relief, the underlying pressures that drove the slide last week haven't disappeared. The coming weeks could bring more volatility, especially with the Fed's December meeting and New Zealand's official results on the horizon.
For now, the Aussie and Kiwi are holding their ground, but investors should stay alert to the forces that could push them off balance again.
