Foreign Currency Mortgages in Australia – 2026 Guide

A foreign currency mortgage is a home loan where the debt is denominated in a different currency than the country where the property is located (e.g., a USD loan for an Australian property).

Today, most mainstream Australian lenders no longer offer true foreign currency loans due to strict APRA regulations. Instead, expats and foreign citizens can borrow in Australian Dollars (AUD) and use their foreign-earned income to service the loan.

What Is A Foreign Currency Mortgage?

A true foreign currency mortgage allows you to borrow in a foreign currency (like USD) to buy Australian property. Conversely, a foreign income mortgage allows you to borrow in Australian Dollars (AUD) while proving your ability to repay the debt using income earned overseas.

While some international banks and specialist private lenders may still offer true foreign currency loans on a case-by-case basis for high-net-worth individuals, the standard route is now the foreign income mortgage.

How Much Can I Borrow? (Lending Limits and LVR)

When applying for a mortgage using foreign income, you can typically borrow up to a maximum of 60% of the property value. However, Lenders Mortgage Insurance (LMI) is available to push this to a 70% or 80% Loan to Value Ratio (LVR) under specific expat conditions.

There is no strict limit on the total loan amount you can secure, provided it remains below the required LVR and meets all standard Australian lending criteria, including proof of income and serviceability.

Different lending policies will apply depending on whether you are an Australian citizen living overseas, a foreign citizen living overseas, or a temporary resident in Australia.

How Banks Assess Foreign Income? (The 20% Haircut)

Banks use a practice called “income shading” or a “haircut” to protect against currency fluctuations. When assessing your serviceability, they will typically discount your foreign income by 20% to 30% to ensure you can afford the loan even if exchange rates drop.

For example, if a borrower earns $100,000 USD, the bank may only assess $80,000 USD of it to calculate borrowing capacity. This creates a safety buffer for both the lender and the borrower.

Acceptable vs. Unacceptable Foreign Currencies

Australian lenders categorize foreign currencies into tiers based on global economic stability and trade ease.

Tier 1 currencies are widely accepted, Tier 2 are reviewed on a case-by-case basis, and others are generally deemed unacceptable for servicing an Australian mortgage.

Below is a breakdown of how Australian banks view different global currencies:

Note: Investment policies change regularly. Some countries may also be excluded entirely due to international tax issues or trade embargoes.

What Does APRA Say About Foreign Currency Loans?

The Australian Prudential Regulation Authority (APRA) advises banks to apply strict discounts to offshore income to mitigate international risk. Because validating offshore income is difficult, mainstream Australian “Big 4” banks no longer offer true foreign currency loans.

APRA’s prudential practice guide highlights the massive challenges banks face when validating offshore income streams and tax returns. As a result, most lenders have taken this advice to heart, opting to eliminate true foreign currency mortgages to safely manage their exposure.

Exchange Rate Risks And Margin Calls

If there is a significant exchange rate movement, your bank may issue a margin call. You will be required to provide additional real estate security or pay down the loan immediately to ensure the bank’s security position remains within acceptable risk guidelines.

To understand the severe risk of borrowing in a foreign currency, consider this example:

If your loan is $900,000 US, the property is worth $1,500,000 AU, and the exchange rate is 1:1, your LVR is 60%.

However, if the AU drops so that each AU dollar only buys 80 cents US, your LVR drastically changes. The loan’s AU equivalent is now $1,125,000 on a property worth $1,500,000. Your LVR has jumped to 75%.

Because this exceeds the 60% limit acceptable to the bank for a foreign currency mortgage, they would force a margin call. You would need to provide additional real estate in Australia as collateral or make a massive lump-sum payment to bring the debt back down to the $900,000 AU equivalent.

Consequently, a much safer approach is to simply borrow in Australian dollars using a foreign income mortgage.
