The Fed's Next Move: Why Higher Rates Could Be Singapore Banking's Best Friend Again

Central bankers spent most of 2025 congratulating themselves for finally taming inflation without breaking the economy. Then the Strait of Hormuz got complicated, oil prices woke up, and the whole narrative got messier.

The US Federal Reserve holds its next policy meeting on 16 September 2026, and for the first time in years, a rate hike is a live enough possibility that strategists are revising their calls. J.P. Morgan Wealth Management has shifted its base case from "on hold" to a quarter-point increase, citing Iran-conflict-driven supply chain disruption keeping energy costs elevated, layered on top of markets already questioning the Fed's inflation-fighting resolve after it held rates steady in July. Three FOMC members — Beth Hammack, Neel Kashkari, and Lorie Logan — dissented at that meeting, all wanting to raise, not cut.

Where the Fed Connects to Your SORA-Linked Loan

Singapore's exchange-rate-based monetary policy is a different mechanism from the Fed's rate-setting, but it isn't a disconnected one. SORA — the Singapore Overnight Rate Average, the key benchmark for most floating-rate SGD loans — sits inside an open, capital-mobile economy where global USD funding conditions, cross-currency flows, and money-market liquidity all feed into local rates. Fed policy doesn't move SORA one-for-one or on a fixed lag, but a sustained hike or a longer pause before cutting puts real upward pressure on Singapore dollar funding costs over time, even as MAS operates through its own separate exchange-rate policy framework.

SORA has spent 2026 sitting near multi-year lows, in the 1.1%–1.3% range, a long way down from its 2023 peak above 3.7%. That's a comfortable place to be. It also means borrowers have gotten used to unusually low funding costs, and a Fed hike — or even just a longer pause before the next cut — is exactly the kind of external pressure that could push SGD funding costs back up.

For households, that means mortgage repayments that have felt unusually gentle for the past year or so may not stay that way, particularly for anyone on a SORA-linked package whose fixed-rate lock-in is expiring. For businesses, it means working capital and trade financing lines that reprice on similar benchmarks. Neither is catastrophic at current levels. Both are worth planning for before the September and October MAS reviews land, rather than after.

How Singapore's Banks Actually Make Money When Rates Rise

This is the part that gets lost in the doom-and-gloom framing: rising rates are not universally bad news, and they're not universally good news either. What actually determines the outcome isn't the direction rates move — it's whether a bank's balance sheet is built to benefit from that direction. For Singapore's banking sector, the 2022–2023 hiking cycle is a real-world case study in what "built to benefit" looks like.

The mechanism is net interest margin, or NIM — the spread between what a bank earns on its loans and investments and what it pays out on deposits and borrowings. The trick to understanding why rising rates favour banks so quickly is that a bank's assets and liabilities don't reprice at the same speed. SORA-linked loans reprice monthly or quarterly, almost automatically. Deposits are stickier — a fixed deposit you locked in at January's rate keeps paying that rate until it matures, regardless of what happens to the market in between. So the moment rates rise, banks are earning the new, higher rate on a fast-moving loan book while still paying the old, lower rate on a slower-moving deposit book. That timing gap, multiplied across a balance sheet worth hundreds of billions, is where the margin expansion actually comes from — and it persists for as long as it takes the deposit book to fully catch up.

Banks don't profit from rates being high. They profit from the gap between how fast their loans reprice and how slowly their deposits do — which means the real edge isn't guessing where rates go, it's how well the balance sheet is built for the lag.

Singapore's three local banks are unusually well positioned to stretch that gap further, for one structural reason: a current account and savings account (CASA) ratio that has historically run around 50% or higher across the trio. CASA money has no fixed maturity date and tends to be far less rate-sensitive than fixed deposits or wholesale funding, because customers are behaviourally sticky — most people don't switch banks over an extra 0.2% on money they use for daily spending. That gives banks a real funding cost advantage, though not an unconditional one: banks can and do raise savings rates or run promotions when they need to defend the deposit base, and customers can and do move.

In fact, they did exactly that. DBS's own reporting describes industry-wide CASA outflows starting mid-2022 as rising rates sent depositors chasing yield, with fixed deposits absorbing the difference — a shift that only started easing through 2023 as deposit costs rose more slowly than loan yields. So the CASA advantage isn't a static moat that just sat there collecting the upside. It eroded in real time even as the banks that managed the mix well kept the arithmetic in their favour. That's a more interesting story than "banks have cheap deposits": the FY2022–23 NIM expansion happened despite CASA erosion, not because it held steady.

Against that backdrop, DBS's Commercial Book NIM jumped 48 basis points to 2.11% in FY2022, and combined net interest income across DBS, OCBC, and UOB rose roughly 30% to near S$27 billion. By the first quarter of 2023, all three banks reported record quarterly net profits — UOB at S$1.6 billion, DBS at S$2.57 billion, OCBC at S$1.88 billion — though it's worth separating cause from effect here: net interest income growth from the repricing gap was the biggest driver, but wealth management fees, trading income, and lower provisions also moved those headline profit numbers, so NIM expansion alone doesn't explain the full picture.

Capturing the upside also isn't automatic or instant. It requires active asset-liability management: repricing loan books quickly, laddering fixed-deposit maturities so the back-book renews gradually instead of resetting all at once, and using interest rate swaps to fine-tune how much of the loan book stays exposed to rate moves versus how much gets hedged. Banks with faster asset repricing and disciplined funding management tend to see the margin benefit show up relatively quickly, though the exact timing and size vary a lot depending on loan mix, deposit behaviour, and hedging positions — there's no universal clock on it.

The CASA story also cuts the other way for banks that get complacent: it only holds up while depositors stay lazy. When rates were near zero, nobody bothered chasing yield on their savings. When SORA and T-bill yields climb, that changes fast — Singapore's 2022–2023 rate cycle demonstrated clearly that depositors will move cash the moment the yield gap becomes meaningful, with retail money flowing into Singapore Savings Bonds and T-bills that paid more than most banks' fixed deposits. A bank that doesn't compete on deposit pricing in a rising-rate environment can watch the very funding base that makes its NIM story work simply walk out the door.

The Cautionary Tale: When Rate Risk Isn't Managed

Rising rates don't only create winners, and Silicon Valley Bank's collapse in March 2023 is the textbook case of what happens when a financial institution gets the other side of the exact same trade badly wrong — proof that the same timing gap that pads a Singapore bank's NIM can just as easily gut a balance sheet built the wrong way round.

SVB had parked a large share of its balance sheet in long-dated government bonds and mortgage-backed securities purchased when rates were near zero. As the Fed's hiking cycle progressed, those bonds lost significant market value — a classic duration mismatch, since SVB's deposit base was short-term and rate-sensitive while its assets were locked in at yesterday's low rates. When the losses became public and a concentrated, largely uninsured depositor base — heavily weighted toward tech startups with tightly networked funding circles — started pulling funds, the bank was insolvent within days. Regulators closed it that same week.

The lesson isn't "rates are dangerous." It's that interest rate risk is a discipline banks have to actively manage, not a side effect they can enjoy the upside of and ignore the downside of. It's a balance sheet strategy question, a liquidity management question, and — in SVB's case specifically — a question of how quickly a digital, always-online depositor base can trigger a bank run at a speed old contingency plans never anticipated. Singapore's banks operate under a considerably more conservative liquidity and capital regime than SVB did, but a bank that collapsed within a week is a low bar worth stress-testing against rather than resting on.

What This Means for You

For businesses:

• If your working capital or trade financing lines are on floating SORA-linked rates, run a 100–150 basis point upward stress test on your debt servicing costs before September, rather than waiting for the market to make the scenario real.

• Review fixed-versus-floating loan structures now — SORA near multi-year lows is a reasonable moment to lock in a longer fixed-rate package if your lock-in period allows it.

• If you're a treasury or finance function at a financial institution, revisit your asset-liability duration gap and deposit repricing strategy before the rate move, not in reaction to it.

• Diversify funding relationships rather than concentrating exposure with a single lender or counterparty — a lesson SVB's tech-sector clients learned the hard way.

For individuals:

• If your mortgage lock-in period is expiring in the next three to six months, compare fixed and SORA-linked floating packages now rather than defaulting to a renewal.

• Rising rates are good news for savers — watch T-bill and Singapore Savings Bond yields, and don't assume your bank's fixed deposit rate is automatically competitive.

• Build a repayment buffer into your budget rather than assuming today's low SORA environment is permanent.

• Avoid taking on new large floating-rate debt right before a genuinely two-sided rate decision — certainty about direction is exactly what's missing right now.

  
  

The Fed meets on 16 September. MAS's next scheduled review follows in October. Whichever way the dot plot tips, the institutions and households that come out ahead won't be the ones who guessed correctly — they'll be the ones who prepared for both outcomes.
