• Kaplan says bond markets are overpricing further Fed hikes, a day after the Fed's September 16 move to a 3.75%-4.00% target range.
• The UAE's central bank mirrored the Fed within a day, lifting its Overnight Deposit Facility base rate 25 basis points to 3.90% because the dirham is dollar-pegged.
• Saudi Arabia's riyal carries the same dollar peg, so SAMA operates under the identical structural constraint regardless of the exact timing of its own next move.
• If Kaplan's shallower path holds — one more Fed hike to roughly 4%-4.25%, then a pause — Gulf funding costs stabilize on the Fed's calendar, not a separate one.
• The transmission is mechanical, not a trading signal: pegged Gulf central banks have no independent rate lever while the pegs hold.

Robert Kaplan, Goldman Sachs vice chairman and former president of the Federal Reserve Bank of Dallas, said in a September 17, 2026 CNBC interview that bond markets are pricing in more Federal Reserve hikes than are likely to arrive. The comment lands a day after the Fed itself raised its target range a quarter point to 3.75%-4.00%, a move the UAE's dollar-pegged central bank matched within 24 hours. For Gulf markets, Kaplan's overpricing argument is a direct read on the region's own cost of capital, transmitted mechanically through the currency peg rather than through any independent Gulf decision.

The Fed's September Move

The Federal Open Market Committee voted 12-0 on September 16, 2026 to raise the federal funds target range by 25 basis points to 3.75%-4.00%, effective the same day, according to the Fed's own statement. The Committee said inflation remains elevated relative to its 2% goal even as economic activity expands at a solid pace and employment keeps pace with the workforce, framing the increase as supporting both sides of its dual mandate.

What Kaplan Actually Said

Kaplan told CNBC the appropriate path is one more hike, to roughly 4%-4.25%, then a pause — a materially shallower trajectory than what he said bond markets had priced in: three or more additional hikes stretching out toward mid-2027. He made similar points in a Goldman Sachs Exchanges commentary, arguing the Fed's own signals point to a near-term stop that the futures curve was not yet reflecting.

The Dirham Peg Transmits It Within a Day

The Central Bank of the UAE raised the base rate on its Overnight Deposit Facility by 25 basis points, to 3.90% from 3.65%, effective September 17, 2026 — a move it said followed directly from the Fed's own rate decision, per its press release. Because the dirham is pegged to the dollar, the CBUAE has no independent lever to hold rates steady while the Fed moves; Saudi Arabia's riyal carries the same peg, putting SAMA under the identical structural constraint.

Why Tadawul, DFM and ADX Investors Should Care

A shallower Fed path, if Kaplan's read holds, would ease one mechanical drag on Gulf equity valuations: the discount rate used to value future earnings on the Tadawul, the DFM and the ADX falls as expected terminal rates fall. The reverse also holds — every basis point markets keep pricing in beyond what the Fed actually delivers is a basis point of unnecessary drag on multiples across the three exchanges, independent of any single company's earnings trajectory.

What to Watch Next

The Fed's next scheduled decisions, and any further CBUAE or SAMA moves that track them, are the concrete test of Kaplan's call. A hike beyond the roughly 4%-4.25% level he flags, or a pause that undershoots what markets have priced, will show up first in the CBUAE's and SAMA's own rate statements, since both central banks' pegs leave them no independent lever to pull.
