Morgan Stanley analysts said on Monday that they now expect the U.S. Federal Reserve to cut rates in September and then again in October.

"Trade's 'simmer' has begun to boil, business sentiment and capex (capital expenditures) have softened further, global growth remains weak and inflation expectations have fallen," while the gap between 3-month and 10-year U.S. government bonds points to overly restrictive monetary policy, the investment bank's analysts said in a note.

The analysts previously predicted a cut in October alone, saying the central bank would "wait for further evidence that downside risks are weighing on the economy."

Morgan Stanley analysts see an even steeper path ahead, CNBC reports, predicting that four more rate moves will come next year, taking the funds rate close to zero, where it was during the financial crisis and seven years after

The bank joins a number of investors betting that the Fed's first rate cut since 2008, late last month, will be the first of several moves to lower borrowing costs. Goldman Sachs said earlier this month it sees a strong chance of rate cuts in both September and October.
