When conflict erupts in one corner of the world, its tremors travel through the invisible architecture of global finance, arriving quietly at the doorsteps of ordinary households. New Zealand's two largest banks, ANZ and Westpac, have raised fixed home loan rates — some by as much as 0.26 percentage points — citing the rising cost of borrowing on wholesale markets unsettled by Middle East tensions. It is a reminder that in a deeply interconnected world, the price of peace, or its absence, is never paid in one place alone.
ANZ raises home loan rates up to 0.26% citing Middle East conflict impact
When global uncertainty pushes up funding costs, it puts upward pressure on lending rates
Mark
Why does a conflict halfway around the world affect what New Zealanders pay on their mortgages?
Mimi
Because banks don't lend from their own money. They borrow from global wholesale markets—think of it as a bank needing to borrow to lend. When geopolitical tension makes those markets nervous, the price of borrowing goes up. ANZ and Westpac have to pay more to get the funds they need, so they pass that cost on.
Mark
But couldn't they just absorb the cost themselves?
Mimi
They said they're absorbing some of it. But if they absorbed all of it, they'd be lending at a loss. The wholesale rates have jumped more than 0.30% in a month. That's significant enough that banks have to move.
Mark
Who actually benefits from this?
Mimi
Savers, clearly. Term deposit rates are up 0.10 to 0.30 points. If you have money sitting in the bank, you're earning more. But borrowers are worse off, unless they're one of the 44% of ANZ customers who got ahead on payments during the easing cycle.
Mark
Is this temporary?
Mimi
That depends on the Middle East. If tensions ease and wholesale rates fall, rates could come back down. But right now, both major banks are signaling this is the new reality until global uncertainty settles.
Mark
What happens to people who can't afford the increase?
Mimi
ANZ said to call them. The bank knows some households are stretched. They're offering to discuss options—restructuring, payment holidays, that kind of thing. But the underlying pressure is real.
The Pulse
- Middle East conflict has pushed offshore wholesale funding costs up more than 0.30 percentage points in a single month, forcing banks to act.
- ANZ lifted fixed rates across six-month to three-year terms on Thursday, with the 18-month rate climbing to 5.45%; Westpac moved similarly the week before.
- Borrowers face higher repayment burdens, while savers receive a rare benefit — ANZ's six-month term deposit rate now sits at what the bank claims is the market's highest.
- Both banks insist they are absorbing part of the cost rather than passing it on in full, framing the increases as a reluctant but necessary response to market reality.
- Roughly 44% of ANZ home loan customers hold at least six months of repayment buffer, offering some households a degree of protection against the immediate sting.
When conflict erupts in one corner of the world, its tremors travel through the invisible architecture of global finance, arriving quietly at the doorsteps of ordinary households. New Zealand's two largest banks, ANZ and Westpac, have raised fixed home loan rates — some by as much as 0.26 percentage points — citing the rising cost of borrowing on wholesale markets unsettled by Middle East tensions. It is a reminder that in a deeply interconnected world, the price of peace, or its absence, is never paid in one place alone.
New Zealand's largest bank raised the cost of fixed home loans on Thursday, responding to a surge in global wholesale funding costs that both ANZ and Westpac attribute to uncertainty generated by the Middle East conflict. ANZ's increases spanned six-month to three-year terms, with the 18-month rate seeing the steepest rise — up 0.26 percentage points to 5.45%. The one-year and two-year rates each climbed 0.20 points, to 4.99% and 5.49% respectively, while shorter and longer terms moved more modestly or held steady.
The mechanism is straightforward but easy to overlook: banks do not lend solely from their own reserves. They draw on offshore wholesale markets to fund mortgages, and when geopolitical tension makes those markets more volatile and expensive, the cost flows downstream. ANZ's personal banking managing director Grant Knuckey acknowledged the pressure while framing the increases as a partial pass-through — the bank, he said, was absorbing some of the rise rather than shifting it entirely onto customers.
Westpac moved first, raising its own fixed rates last week and noting that wholesale rates had climbed more than 0.30 percentage points in just a month. Both banks positioned their decisions as reluctant but unavoidable responses to conditions beyond their control.
The picture is not uniformly bleak. ANZ simultaneously lifted term deposit rates by up to 0.30 percentage points, offering savers meaningfully better returns. And the bank revealed that around 44% of its home loan customers are at least six months ahead on repayments — a buffer many built by maintaining higher payment levels as rates fell. Knuckey extended an open invitation to any borrower feeling the strain, signalling that the bank is prepared to work through options with those who need it.
New Zealand's largest bank moved to raise the cost of borrowing on Thursday, lifting fixed home loan rates across most terms in response to what it says is a spike in the price of money on global markets. ANZ increased rates on loans locked in for six months to three years, with the steepest climb hitting the 18-month term—up 0.26 percentage points to 5.45%. The six-month rate rose 0.10 points to 4.79%, the one-year jumped 0.20 points to 4.99%, the two-year lifted 0.20 points to 5.49%, and the three-year climbed 0.10 points to 5.59%. Longer terms of four and five years held steady. The bank's special rates, available to customers with at least 20% equity and a salary-credited ANZ transaction account, moved in lockstep with standard rates.
The culprit, according to ANZ's personal banking managing director Grant Knuckey, is the Middle East conflict and the uncertainty it has created in global financial markets. Banks don't lend from their own pockets alone—they borrow from wholesale markets around the world to fund mortgages and other loans. When geopolitical tension makes those offshore funding sources more expensive, that cost gets passed along. Knuckey explained that wholesale rates had climbed significantly in recent months, making it costlier for ANZ to borrow the money it needs to lend out. The bank said it was trying to balance the interests of borrowers and savers while keeping rates aligned with actual market conditions.
ANZ is not navigating this alone. Westpac, the country's second-largest bank, made a similar move last week, raising its own fixed rates on one to three-year terms and citing the same geopolitical pressures. Westpac's managing director of consumer banking, Helen Ryder, noted that wholesale interest rates had climbed more than 0.30 percentage points in just the past month. Both banks framed their increases as a partial pass-through of those higher costs—they said they were absorbing some of the pressure rather than shifting it all to customers.
The rate rises create a pinch for borrowers, but they come with a silver lining for savers. ANZ lifted term deposit rates by 0.10 to 0.30 percentage points across six-month to two-year terms. The six-month rate now sits at 3.55%, which the bank said is the highest available in the market. The 18-month and two-year rates both rose 0.30 points, landing at 4.20% and 4.30% respectively. For households with savings, these increases offer better returns than they've had in some time.
Not all borrowers face equal pressure from the move. ANZ disclosed that around 44% of its home loan customers are at least six months ahead on their repayments—a buffer built up during the period when interest rates were falling and many households chose to keep paying at higher levels rather than reduce their payments. That cushion may help some weather the increase. Still, Knuckey invited any customers experiencing financial strain to contact the bank to discuss available options. The message was clear: the bank knows this hurts, and it's ready to talk.
