The Fed raised rates. Is that automatically good for DBS, OCBC and UOB?

What did the Fed actually do?

The Federal Open Market Committee voted unanimously on 16 September 2026 to raise the federal funds target range by 25 basis points, from 3.50%–3.75% to 3.75%–4.00%. It said economic activity remained solid and inflation was still elevated.

The Fed’s median projection for the policy rate was 4.1% at the end of both 2026 and 2027, up from June projections of 3.8% and 3.6%. With the current range centred around 3.875%, the new 2026 median is broadly consistent with one more quarter-point increase by year-end.

That is a projection, not a promise. The path can change as inflation, employment, energy prices and financial conditions change.

Does the Fed control Singapore interest rates?

Not directly. Singapore’s monetary policy is centred on the exchange rate: MAS manages the Singapore dollar against a basket of currencies within a policy band.

Singapore also has open capital markets, so local funding conditions are influenced by global rates, investor flows and expectations for the Singapore dollar. The local benchmark investors commonly encounter is SORA, the Singapore Overnight Rate Average, which reflects actual unsecured overnight Singapore-dollar borrowing transactions between banks.

DBS, OCBC and UOB also operate and fund assets in multiple currencies. The effect of a US rate increase depends on each bank’s Singapore-dollar, US-dollar and regional balance sheets.

What is net interest margin?

Net interest margin, or NIM, measures the interest a bank earns from assets such as loans and securities relative to what it pays to fund them.

Suppose a bank earns 5% on its loans and securities and pays 2% for funding. Its simplified spread is three percentage points. If lending yields rise to 5.25% while funding costs stay at 2%, the spread improves. If deposit costs rise to 2.35%, however, the spread narrows despite the rate increase.

That is why “higher rates equal higher NIM” is not a reliable rule.

How the hike could help the banks

Loans may reprice higher

Some corporate, housing and commercial-property loans use floating rates or reprice periodically. If the relevant benchmark rises, banks can receive more interest without issuing a new loan. A three-month reset reacts faster than a fixed-rate loan.

Cash and liquid assets may earn more

Banks hold cash, central-bank balances and high-quality securities. Higher short-term rates can improve returns on some of these assets, particularly where surplus deposits can be deployed at better yields.

Low-cost deposits become more valuable

Current and savings accounts, often called CASA, may pay little or no interest. A stable pool can fund assets more cheaply than fixed deposits or wholesale borrowing. But customers can shift money to fixed deposits, Treasury bills or money-market products. The speed at which deposit costs respond is known as deposit beta.

How the hike could hurt

Deposit competition can become expensive

If one bank raises fixed-deposit rates, rivals may have to respond or risk losing funding. Deposit costs can rise before every loan has repriced.

Borrowing demand may weaken

More expensive financing can cause households and businesses to postpone borrowing or repay balances. A larger margin on a shrinking loan book is not necessarily better than a slightly smaller margin on healthy growth.

Credit stress can emerge later

Defaults rarely appear the day after a rate increase. Pressure builds as refinancing becomes more expensive or cash flow weakens. Higher allowances for loan losses can offset extra interest income.

Bond values can fall

When market yields rise, existing lower-yielding bonds generally lose market value. The accounting effect depends on classification, hedging and whether the bank plans to hold the securities to maturity.

What the latest bank results tell us

These results were reported before the 16 September increase. They are a baseline, not evidence of the hike’s eventual effect. The reporting periods also differ, so the figures are not a perfect ranking.

DBS

DBS’s second-quarter NIM fell 18 basis points year on year to 1.87%. Net interest income declined 2%, even as loans and deposits grew. Quarterly net profit reached S$3.08 billion as fee income, treasury customer sales and trading income strengthened. Wealth-management fees rose 42%, and wealth assets under management exceeded S$500 billion.

OCBC

OCBC’s first-half NIM fell 25 basis points year on year to 1.73%, while net interest income declined 3%. Net profit nevertheless rose 13% to S$4.19 billion. Non-interest income increased 36% to a record S$3.51 billion and its non-performing-loan ratio remained 0.9%. Its insurance business adds another layer: higher reinvestment yields can help, while bond values, liabilities and market conditions can pull in different directions.

UOB

UOB’s second-quarter NIM fell eight basis points from the previous quarter to 1.74%, mainly because lower benchmarks reduced asset yields. Net interest income declined 2% year on year, while net profit rose 10% to S$1.48 billion. Its ASEAN footprint means Singapore and US rates are only part of the picture.

Which bank benefits most?

The Fed announcement alone cannot answer that. Compare:

• How quickly loans reprice
• The stability of CASA deposits
• How fast deposit costs rise
• US-dollar assets and funding
• Loan growth across major markets
• Borrower quality and credit costs
• Interest-rate hedges
• Fee, insurance and trading income
• The valuation already in the share price

A bank with faster asset repricing and slower deposit-cost increases may gain more near term. One with strong fee growth may be less dependent on NIM altogether.

Possible beneficiaries and pressure points on SGX

Possible beneficiaries

Banks with strong low-cost deposit franchises. Sticky current and savings deposits become more valuable as asset yields rise, provided customers do not rapidly switch into costlier fixed deposits.

Banks with floating-rate corporate lending. These assets can reprice quickly when customers remain healthy and demand holds up.

Insurance businesses reinvesting maturing assets. Businesses such as Great Eastern may reinvest cash flows at higher yields, though liability values and existing bond portfolios complicate the overall effect.

Pressure points

S-REIT and property borrowers. Higher refinancing costs can weaken interest coverage and property demand, affecting both REIT investors and their lenders.

Small businesses and leveraged consumers. Borrowers with thin cash-flow buffers may struggle to absorb higher repayments.

Banks chasing deposits. The expected margin benefit can disappear if deposit rates rise quickly.

Dividend expectations. One rate increase does not automatically produce a higher bank dividend. Capital requirements, losses, investment needs and payout policy still matter.

Six common mistakes

1. Assuming every rate increase widens NIM

Funding costs may rise faster than loan yields.

2. Treating the Fed rate as Singapore’s interest rate

SORA is determined in the Singapore-dollar market and can respond differently.

3. Ignoring deposit behaviour

Customers can move from low-cost accounts into higher-paying alternatives.

4. Looking only at NIM

Loan growth, fees, trading, insurance, expenses and provisions all affect profit.

5. Assuming higher earnings mean a higher dividend

Dividends depend on capital, policy and sustainable earnings.

6. Treating Fed projections as guaranteed

The projected path can change with inflation, employment and financial conditions.

What should investors watch next?

SORA and deposit rates

Check whether local benchmark rates rise and whether banks increase fixed-deposit promotions.

Third-quarter bank margins

The September increase occurred late in the quarter, so its full effect may not appear immediately. Listen for comments on asset repricing, deposit beta, hedging, NIM guidance and loan demand.

Loan growth and asset quality

Watch non-performing loans, newly troubled assets, specific allowances and total credit costs. Higher margins are less useful if borrowing contracts or losses rise.

Fee income and the next Fed signals

Wealth-management, cards, transaction banking and treasury fees can reduce reliance on interest income. Use the Fed’s official statements rather than assuming its September projections will be delivered exactly.

Your bank-investor checklist

• Record current NIM
• Compare quarterly and yearly NIM
• Check net interest income
• Review loan growth by market
• Compare deposit and loan growth
• Check the CASA mix
• Read comments on deposit competition
• Review problem loans and allowances
• Record total credit costs
• Examine fee and wealth income
• Separate recurring earnings from one-offs
• Check the CET1 capital ratio
• Review ordinary and special dividends separately
• Compare valuation with sustainable return on equity

Key takeaways

• The Fed raised its target range to 3.75%–4.00% on 16 September 2026.
• Its projections point to higher-for-longer rates, but they are not promises.
• The Fed does not directly set SORA or Singapore monetary policy.
• Higher rates can improve asset yields, especially on floating-rate loans and liquid assets.
• Deposit competition, weaker borrowing and credit stress can offset the benefit.
• DBS, OCBC and UOB recently grew profits despite falling NIMs, showing the importance of non-interest income.
• Judge each bank by asset repricing, funding costs, loan growth and credit quality—not the headline alone.
