Importers are already paying for an election nobody has won yet

Financial markets have stopped waiting for 7 November. Traders are actively pricing the chance of a left-leaning government, and the cost is landing where business feels it fastest, in the exchange rate and the price of everything shipped in. The NZ Herald reported today that traders fear a left-leaning government could worsen the cost of living, with a weaker currency as the transmission channel.

The move is already well underway. The kiwi has fallen around 6% against the US dollar since late August, the NZX 50 has lost momentum since an August record high, and National and Labour are both polling below 30% with smaller parties holding the balance. For context, the dollar has dropped an average of 0.5% in the month after each of the past six elections. This time the market has done roughly twelve times that before polling day.

One policy is doing most of the damage

The lazy read is that markets simply dislike the left. The sharper read is that they are pricing one identifiable policy, Labour’s pledge to restore the Reserve Bank’s dual mandate of inflation plus full employment. Reuters identified that commitment as the policy investors are watching, and NBR reports economists see it as the central currency-negative risk.

Sean Keane, chief strategist for Asia Pacific at JB Drax Honore, told the Herald that “the New Zealand dollar will sell off sharply as investor appetite diminishes in anticipation of higher taxes and more government interference in the economy.” He expects short-term rates to fall as the RBNZ’s inflation focus dilutes, while longer-term bond yields rise on fiscal risk. That combination means a weaker dollar and dearer long-term borrowing at the same time.

The fiscal literacy debate has not helped. The Herald notes Green co-leader Marama Davidson was corrected in the campaign’s final week for believing government debt carries 1-2% interest, when the real cost is 4-5%. The Herald’s Wellington business editor Jenee Tibshraeny unpacked the market nerves on Newstalk ZB tonight.

Credibility is the real currency

This is not purely a left-wing problem. Reuters points out the current coalition unsettled investors itself by scrapping major transport projects after taking office, and that a one-term government now looks possible for the first time since 1975.

Dr Bryce Wilkinson of the New Zealand Initiative argues the slide is broad-based, hitting the dollar against all 17 currencies the RBNZ tracks, with NZD/AUD at 81 cents, the lowest since early 2013 against a decade average near 90. He blames the RBNZ’s September decision, populist supermarket rhetoric, rising debt and persistent deficits as much as the polls. “Markets appear to be telling us something unpalatable about New Zealand in particular,” he wrote, adding that the next government faces the same need to attract overseas capital because “policy credibility is key.”

That is the right frame. New Zealand is a large net capital importer. Whoever wins on Saturday is borrowing from the same foreign investors who are marking the kiwi down this week.

Import costs were already running hot

The currency is falling onto an economy already absorbing an inflation shock. RBNZ data shows June import prices up 15.2% year-on-year and 13.7% in the quarter, while export prices rose a modest 4.4% annually. Treasury’s Pre-Election Fiscal Update flagged Middle East oil volatility pushing up prices and interest rates, alongside subdued household spending. In May, the Budget forecast the trade-weighted index would rise gradually to around 70. That baseline now looks optimistic.

The damage will not arrive overnight. A 2025 RBNZ analytical note found exchange rate pass-through to prices was slow and incomplete, building over time. Expect it to surface over the next one to two quarters in fuel, machinery, electronics and building materials, as existing stock and old contracts roll off.

Uncertainty costs more than any outcome

Greg Smith of Generate Investment Management made the key point: “Markets are generally reasonably good at pricing a policy once they know what it is. What they find more difficult is prolonged uncertainty.” NBR similarly reports a clear result of either stripe would support the dollar. With minor parties polling around a third of the vote, weeks of coalition haggling is the worst-case scenario for anyone holding open FX positions.

Hedge now, argue later

The practical lesson is simple. Businesses with US dollar import contracts, offshore debt or thin margins on imported inputs should not wait for election night to decide what to do. The market has already made its call, and if Keane is right, a change of government with strong Green representation means another leg down. If he is wrong, a relief rally is a pleasant surprise, not a business plan.

Whoever forms the next government will inherit a currency that has passed judgement before they have said a word. Earning back that credibility, with a clear fiscal plan and a central bank investors trust, is the first test. Until then, cover your exposure.
