Rate decision imminent: markets bet on a 94% probability of a rate hike; holding steady could be the biggest "dovish surprise" in over 30 years.

As the Federal Reserve prepares to announce its rate decision on Wednesday, bond traders have all but concluded that a rate hike will be the final outcome. Interest rate swaps tied to Fed meeting dates show the market currently expects Fed Chair Warsh and his colleagues to raise the benchmark rate by 25 basis points with about 94% probability, equivalent to roughly 23 basis points of tightening already priced in. The current federal funds rate target range is 3.50%-3.75%. If the Fed raises rates by 25 basis points as the market expects, the policy rate range would rise to 3.75%-4.00%. Historical experience shows that when market expectations for a rate hike reach current levels, the Fed has almost never disappointed traders. According to Bloomberg-compiled data since 2008, whenever market-implied hike probabilities reached such elevated levels, the Fed ultimately delivered a hike. Deutsche Bank strategists, citing fed funds futures data, further noted that if the Fed unexpectedly chooses to hold steady on Wednesday, it would be the "largest dovish surprise" at a regularly scheduled policy meeting since the Fed began formally announcing rate decisions after policy meetings in 1994. "The market is not positioned for a hold or a dovish hike," said Caesar Maasry, head of investment research at Lunate. **Hike probability rises to 94%; Wall Street shifts en masse after inflation data** Market expectations for a September hike have not always been this firm. On the day of the Fed's policy meeting in late July, traders saw only about a 38% probability of a hike, and the Fed ultimately chose to hold rates steady. Because Warsh maintained some ambiguity on how to address inflation, long-term U.S. Treasuries at one point saw significant selling. But the situation this time is markedly different. Expectations for a September hike began rising noticeably last month. At that time, Warsh said the Fed would ensure inflation cools "fast enough," prompting the market to increase bets on further monetary tightening. By last Friday, after U.S. consumer price data was released, traders were almost fully betting on a September rate hike. The data showed that U.S. inflation still showed no clear signs of cooling, with the inflation rate having exceeded the Fed's target for more than five consecutive years. After the data release, several major Wall Street financial institutions quickly revised their rate forecasts, shifting from an originally expected September "hold" to a 25 basis point hike. This pushed the market-implied hike probability further up to the current level of about 94%. **Warsh changes Fed communication style; policy surprise risk rises** For a long time, the Fed has generally sought to avoid surprising financial markets with rate decisions, especially when hiking, because sudden monetary tightening can trigger sharp volatility in bond, stock, and foreign exchange markets. However, since Warsh became Fed Chair in May, uncertainty around policy decisions has increased. Warsh has changed the Fed's long-standing communication approach, no longer clearly signaling the next policy move to the market in advance as was previously done. This means that even when the market forms a highly consensus view, traders still face the possibility of a policy surprise. The July policy meeting was a clear example. At that time, until the day the decision was announced, the market still priced in a 38% probability of a hike, but the Fed ultimately took no action. Still, compared with July, market confidence in a hike is now significantly higher. The 94% implied probability means that for the vast majority of bond traders, Wednesday's question is no longer "whether the Fed will hike," but rather what policy signals Warsh will deliver after the hike. **Some traders hedge against "black swan"; demand for short-term rate options surges** Although a hike is almost fully priced in, some investors are still hedging against the possibility that the Fed unexpectedly holds steady. On Tuesday, demand for short-term rate options that would profit if the Fed unexpectedly keeps rates unchanged increased sharply, indicating that some traders are still willing to pay to guard against a low-probability event. The reason is that if the Fed really holds rates steady when the market has priced in about a 94% probability of a hike, the impact on asset prices could far exceed that of an ordinary policy meeting. On one hand, short-end U.S. Treasury yields could fall rapidly; on the other hand, because the market had been highly confident of further tightening, an unexpected pause could also be interpreted as a clear dovish policy shift. Therefore, even if the probability of such a scenario is very low, the potential market volatility is still enough to attract some investors to seek protection in advance. **Oil price surge intensifies inflation concerns; 10-year Treasury yield rises to highest since 2007** This Fed meeting is especially critical for the bond market because long-term U.S. interest rates have risen to levels rarely seen in nearly 20 years. On Tuesday, the 10-year U.S. Treasury yield rose to its highest level since 2007. The recent sharp rise in oil prices further intensified market concerns about a resurgence in inflation and also pushed investors to reassess the future path of Fed rates. Higher energy prices can pass through to overall prices via gasoline, transportation, and corporate production costs. If inflation remains above target, the Fed may not only need to hike in September, but the market may also further raise expectations for subsequent hikes. Therefore, for the bond market, Wednesday's policy decision itself is only the first layer of risk. More important is whether Warsh will signal that this hike is a one-off move or part of a new tightening cycle. "Tomorrow's Fed meeting will be our most important in some time. With the market having priced in about a 90% probability of a hike, the Fed choosing to hold steady at this point would be almost unprecedented," said Alex Cohen, FX strategist at Bank of America. **Market focus shifts to policy path after the hike** This Fed meeting also has an unusual political backdrop. U.S. President Trump personally nominated Warsh to serve as Fed Chair, but during former Chair Powell's tenure, Trump repeatedly publicly demanded that the Fed cut rates sharply. Now, just months after Warsh took the helm of the Fed, the market is almost certain the central bank will hike further, creating a stark contrast between monetary policy and Trump's long-held preference for low rates. For the market, if the Fed raises rates by 25 basis points as expected on Wednesday, what will likely determine the next phase of moves in U.S. Treasuries, the dollar, and even U.S. stocks is Warsh's statement on the subsequent policy path. With inflation still stubborn, rising oil prices adding further pressure on prices, and the 10-year Treasury yield at its highest since 2007, investors will focus on whether the Fed continues to emphasize fighting inflation and whether there is still room for further hikes this year. Judging from the current roughly 94% probability of a hike, the 25 basis point increase itself has already been highly digested by the market. By contrast, if the Fed unexpectedly holds steady, or if Warsh delivers a clearly dovish signal, that could instead become the biggest market risk of this meeting.
