How Trump’s tariffs could make your mortgage cheaper

The US economy looks like it could be in for a rough time. 

Not only are share markets way down (save yourself the heart attack and don’t check your KiwiSaver). 

But tariffs have two potential impacts:

One is inflationary. If Fonterra wants to export 1 tonne of milk powder to the United States, it might usually cost a US buyer $5,000. 

With a 10% tariff in place, the buyer (the importer) has to pay an extra $500 to the US government. 

So now that 1 tonne of milk powder costs $5,500. 

Prices have gone up, and that’s inflation. However, tariffs can have a deflationary impact. Faced with those higher prices, consumers cut back on their spending.

That can make an already weakening economy worse. 

That’s why financial markets are betting that the Federal Reserve (the United States central bank) will cut interest rates 4 times this year. 

3 months ago, the market was pricing in 1 Fed rate cut this year.

2 months ago, the market was pricing in 2 Fed rate cuts this year.

1 month ago, the market was pricing in 3 Fed rate cuts this year.

And today, the market is pricing in 4 Fed rate cuts this year.

What does that do? 

A lot of investors (especially large fund managers) usually hold their money in the US 

When US interest rates fall faster than expected, they look for better returns elsewhere. 
So they move money out of the US and into other countries (like NZ). 

If there’s more money available, it’s cheaper for banks to borrow. 

And banks pass on those savings to Kiwi borrowers.

Effectively, that means your mortgage could get slightly cheaper. 

This is why the wholesale interest rates have come down after Trump’s tariff announcements (i.e. ‘Liberation Day’).

Does that mean it’s certain? That your mortgage will 100% get cheaper? No, the world is very uncertain at the moment. 

But if we zoom out. The markets are saying that tariffs will harm America’s economy. That can lead to interest rates going down faster. 

Right, back to the interest rate update. 

How much can I negotiate off my interest rate?

Remember, the bank usually discounts their rate when you take out a mortgage. 

So they might advertise 5.25% for the 1-year rate. 

But, when you borrow the money, they might offer you 5.15%.

It’s hard to see these discounts as a borrower. So, I like to share what we’re seeing at Opes Mortgages.

Most banks are offering around 0.1% off each rate. But there’s currently no discount on the cut-price 2-year rate. 

All banks offer 4.99% on the 2-year, and I’m not seeing any discounts.

What are the lowest interest rates in the market?

The lowest rate in the market is still 4.99%. But, this time, it is on the 2-year rate. 

I mentioned last month that one bank was going down to 4.99% on the 1-year. They’ve now increased that to 5.05%.

A good reminder that rates can go up as well as down.

Is it getting harder or easier to get a mortgage?

Some small changes to the servicing test rates, too. 

Remember, although you may actually pay as little as 4.99% … the bank will make sure that you can afford the mortgage at a higher rate.

The lower the test rate, the more you can generally borrow.

The drops since last year are big. But here are the small tweaks that have happened since last month.

What cashback can you get?

No change to cashbacks since last month. Most banks still offer 0.9% - 1% of your loan’s value.
