US Federal Reserve officials, underestimating the spread of credit-market turmoil, focused at their Aug. 7 meeting on inflation and slowing productivity.
Minutes of the session released on Tuesday showed that the Fed was intent on securing credibility as an inflation fighter just 18 months into Chairman Ben Bernanke's term.
Even though the central bank cut the discount rate on Aug. 17, the emphasis on prices forms the backdrop for deliberations next month.
Investors now anticipate policymakers will lower the benchmark rate by a quarter point to 5 percent at or before their Sept. 18 meeting. Anxiety about inflation may keep officials from a larger reduction, or discourage them from signaling a series of cuts, economists said.
"Concerns about upside inflation risk and their credibility will play a role in tempering how aggressively they will be willing to ease," said Brian Sack, vice president at Macroeconomic Advisers LLC in Washington and a former Fed economist.
"It won't prevent them from easing in September," he said.
The central bank did signal greater concern about the threat to the economic expansion from credit markets than it showed in the statement after the Aug. 7 meeting.
A deeper deterioration in financial markets "might require a policy response" depending on the effect on the outlook for growth, the minutes showed.
By Aug. 17, the Fed dropped its reference to inflation entirely when it cut the discount rate and said "the downside risks to growth have increased appreciably."
Records of the emergency videoconference where policymakers changed course won't be released until October.
The central bank at the start of the month still viewed the upheaval in credit markets as concentrated in subprime mortgages, with "little net change in the cost of credit for investment-grade businesses," the minutes showed.
That conclusion overlooked increasing signs of stress in several markets, analysts said. At the time of the Aug. 7 meeting, the stock market had lost about US$1.3 trillion in market capitalization since benchmark indexes reached records last month.
On July 24, Countrywide Financial Corp, the biggest US mortgage lender, reported its third straight decline in quarterly profit, as even prime borrowers struggled with debt payments. The earnings release showed that delinquencies were spreading into less risky loans.
"The minutes indicate they underestimated how severe the problems were in the credit markets," said Scott Minerd, chief investment officer at Guggenheim Partners LLC in Santa Monica, California. "The market was clearly coming unglued prior to the meeting."
Policymakers have employed a range of tools since their last scheduled meeting to ease the credit crunch. They first injected the most funds into money markets since the aftermath of the Sept. 11, 2001, terrorist attacks, then cut the rate charged to banks for direct loans from the Fed.
The Fed has also allowed banks to channel discount-window borrowings to their securities subsidiaries to help improve clients' access to capital. Officials clarified that they will accept as collateral securities such as asset-backed commercial paper sold by special-purpose companies.
Still, financing remains costly or constrained for riskier securities and loans.
"Given the way the market is, I think it would be very difficult" for the Fed to avoid cutting its target rate next month, said John Silvia, chief economist at Wachovia Corp in Charlotte, North Carolina. "The Fed will go ahead and ease 25 basis points in September and then see what happens after that."
