If you've ever wondered why banks refinance loans, you're not alone. Many Filipino homeowners assume refinancing is something banks do purely out of generosity — but the reality is more nuanced, and understanding the bank's perspective can actually help you negotiate better terms for yourself. Banks have clear business incentives to refinance home loans, and when those incentives align with your financial goals, the result can be thousands of pesos in monthly savings.
This guide breaks down exactly why banks refinance loans, what they gain from the process, and — most importantly — how you as a Filipino homeowner can use this knowledge to secure a lower interest rate on your home loan. Whether you're currently paying 8%, 9%, or more on your mortgage, rates as low as 5.99% p.a. may be available to you today through Nook, the Philippines' first digital mortgage broker — at zero cost to you.
When a bank refinances a loan, it means a new loan is issued to pay off an existing home loan — either with the same bank or, more commonly in the Philippines, with a competing bank. The borrower then repays the new loan under fresh terms, which typically include a new interest rate, a new monthly amortisation, and sometimes a new loan term.
From your perspective as a homeowner, refinancing is a chance to reset your mortgage on better terms. For example, if you took out a home loan five years ago at 9% p.a., you might refinance today at 5.99% p.a. — dramatically reducing your monthly payment and the total interest you pay over the life of the loan. The bank that takes on your loan gains a new income-generating asset on its books.
Banks offer refinancing primarily because it is a profitable business activity. When a bank refinances your home loan, it gains a new long-term lending relationship — typically spanning 15 to 25 years — from which it earns interest income month after month. Home loans are considered among the safest assets a bank can hold because they are secured by real property. This makes acquiring home loan borrowers highly attractive to Philippine banks.
Beyond direct interest income, banks also benefit from cross-selling opportunities. A borrower who moves their home loan to a new bank often opens a savings account, gets a credit card, or purchases insurance products from that same institution. This deepens the banking relationship and increases the customer's overall lifetime value to the bank. In a competitive market like the Philippines — where BDO, BPI, Metrobank, Security Bank, and others all compete for quality borrowers — refinancing is a key tool for acquiring and retaining customers.
Yes — banks make money from refinancing in several ways. The most significant source of profit is the net interest margin: the difference between the rate at which the bank borrows money (from deposits and other funding sources) and the rate it charges you on your home loan. Even at a competitive refinance rate of 5.99% p.a., a bank with low funding costs can earn a healthy margin on your loan.
Banks also earn fees associated with processing the new loan, such as appraisal fees, documentary stamp tax, registration fees, and notarial fees — many of which are passed on to the borrower. Additionally, if the refinancing bank requires you to open a salary or savings account as a condition of the loan, it gains a low-cost deposit that further improves its profitability. So while the bank may appear to be doing you a favour by offering a lower rate, it has very concrete financial reasons to do so.
Refinancing is generally good for the bank that acquires the loan and potentially costly for the bank that loses it. The acquiring bank gains a quality, secured asset that generates stable interest income for years or even decades. For the bank losing the loan, it means losing a performing asset and the associated revenue stream — which is why some lenders include prepayment penalty clauses in their loan agreements to discourage early exit.
This competitive dynamic is actually beneficial for Filipino homeowners. Banks compete aggressively to win refinancing business, which is why some institutions regularly offer promotional refinance rates. Understanding this puts you in a stronger negotiating position — you are a valuable customer, and banks will often sharpen their pencils to win your loan.
This is one of the most common questions Filipino homeowners ask — and it has a straightforward answer. A competing bank would rather earn, say, 5.99% p.a. on your loan than earn nothing at all. If your current lender is charging you 8% or 9% p.a. and a rival bank can fund loans at a lower cost, it can offer you a more attractive rate, win your business, and still earn a profitable margin.
Interest rate environments also change over time. The rates available when you first took out your home loan may have been much higher than what is currently offered in the market. Banks regularly update their pricing based on central bank policy rates (the Bangko Sentral ng Pilipinas sets the benchmark rate), their own cost of funds, and competitive pressure from other lenders. If you haven't reviewed your mortgage rate in the last two to three years, there is a strong chance a significantly better rate is available to you today.
Yes, absolutely — and this is in fact the most common and financially rewarding form of refinancing for Filipino homeowners. You are not obligated to stay with your current lender. You can approach any bank or financial institution that offers home loan refinancing and apply to have your outstanding balance transferred to them under new terms.
Philippine banks that actively offer home loan refinancing include BDO, BPI, Metrobank, Security Bank, PNB, RCBC, UnionBank, Chinabank, PSBank, EastWest Bank, and Robinsons Bank. Government-backed refinancing options are also available — for example, if you currently have a Pag-IBIG home loan, you may be able to refinance to a private bank for a significantly lower interest rate and more flexible terms. Nook works with multiple lenders simultaneously, so you can compare offers from many banks in a single application — for free.
The best refinance rate currently available through Nook is 5.99% per annum. This is significantly lower than what most Filipino homeowners are currently paying — rates of 7% to 10% p.a. are common, particularly for loans that were taken out several years ago or originated through government programs like Pag-IBIG.
The exact rate you qualify for will depend on factors such as your loan amount, your remaining loan term, the current appraised value of your property, and your credit profile. However, the difference between 5.99% and even 8% p.a. on a loan of, say, 3,000,000 pesos can translate to savings of over 4,000 pesos per month — or nearly 50,000 pesos per year. Nook helps you identify the best available rate across multiple banks without any cost or obligation.
Your savings depend on your current rate, loan balance, and remaining term — but the numbers can be substantial. Here are two realistic examples for Filipino homeowners:
Example 1: Outstanding balance of 2,500,000 pesos with 20 years remaining at 9% p.a. Your current monthly amortisation is approximately 22,491 pesos. Refinancing to 5.99% p.a. over the same term brings your monthly payment down to approximately 17,890 pesos — a saving of around 4,601 pesos per month, or over 55,000 pesos per year.
Example 2: Outstanding balance of 5,000,000 pesos with 15 years remaining at 8.5% p.a. Current monthly payment is approximately 49,237 pesos. At 5.99% p.a., the monthly payment drops to approximately 42,194 pesos — saving you roughly 7,043 pesos per month. Over the remaining 15 years, that is more than 1,267,740 pesos in total interest savings.
These figures illustrate why refinancing is one of the most powerful financial moves a Filipino homeowner can make. Use Nook's free mortgage calculator to get a personalised estimate based on your actual loan details.
Yes, there are some third-party costs associated with refinancing — but these are typically one-time expenses that are recovered quickly through your monthly savings. Common fees include appraisal fees (for the bank to re-value your property), documentary stamp tax, registration fees with the Registry of Deeds, notarial fees, and in some cases a cancellation fee from your existing lender if you are still within a lock-in period.
Nook's service, however, is 100% free to the borrower. Nook is compensated by the banks, not by you — so you get access to expert guidance, multi-bank comparison, and end-to-end application support at no cost. If you are concerned about refinancing with a challenging credit history, it is still worth exploring your options — read our guide on how to refinance your home loan with bad credit in the Philippines for more information.
A good rule of thumb: if your current home loan interest rate is 1.5 percentage points or more above the best available rate, refinancing is almost certainly worth exploring. Given that the best rate available through Nook is currently 5.99% p.a., this means that homeowners paying 7.5% p.a. or higher are strong candidates for refinancing. Most Filipino homeowners with loans taken out more than two or three years ago fall into this category.
Key factors to consider include: How much of your loan is still outstanding? How many years remain on your term? Are you within a lock-in period with your current bank (which may trigger a prepayment penalty)? What are the one-time costs of switching, and how quickly will your monthly savings offset those costs? Nook's mortgage specialists can answer all of these questions for free, and help you calculate your exact break-even point so you can make a fully informed decision. The process takes minutes to start — and the savings can last for decades.
