Why a Big Bank Just Admitted It Was Wrong About the Dollar

Morgan Stanley gave up its bet that the U.S. dollar would fall and said it was wrong.

The change was reported on Sept. 25, 2026. MarketWatch A Dow Jones-provided version of that account appeared on Morningstar at 3:46 a.m. that same day. Morningstar

The reason given was interest rates. Rising bond yields, or the cost of borrowing, and expected Federal Reserve rate hikes hurt the old forecast, according to the MarketWatch report.

Rates had already shifted. Morgan Stanley predicted two Fed rate hikes, including a small 0.25 percentage point rise at the Sept. 15-16 meeting. Reuters That Sept. 15 forecast put the bank on the higher-rates side of Wall Street thinking for the rest of 2026.

Markets were already expecting tighter policy. They were pricing at least one Fed rate hike in 2026, according to a July 17 note on the Fed pause and fixed-income impact. Morgan Stanley Bond prices had fallen well before September. Across rich countries, borrowing costs rose and long-term rates rose faster than short-term rates, as investors delayed hopes for rate cuts, according to a January review of the global fixed-income reset.

The broader context here is simple. Think of the dollar like money in a savings account. When U.S. rates pay more than other countries, more money wants to stay in dollars. That makes betting against the dollar costly, and it feeds into savings rates, loan costs and returns on foreign investments.

Looking at what this means for investors, the key is time. If high rates keep the dollar strong, bets against it lose money for longer. It also changes the cost of protecting foreign investments from currency swings.

In my view, the lesson is plain. A dollar prediction based on future rate cuts fails when those cuts disappear. Update the view when rates change, do not keep the old call.
