Yet there was no concrete offer of new moves when Bush spoke on a Rose Garden stage just after daybreak, flanked by representatives from nearly a dozen of the world's richest nations and international organizations.
None was expected later in the evening, either, from Bush's appearance at a meeting of the world's richest countries and fastest growing. That session was held at the headquarters of the International Monetary Fund, blocks from the White House.
The global crisis dominated discussions at the annual meetings of the IMF and World Bank over the weekend. The 185-nation IMF strongly endorsed the G-7 plan to do everything possible to protect the financial system and get credit flowing again.
"The depth and systemic nature of the crisis call for exceptional vigilance, coordination and readiness to take bold action," the IMF said in a joint statement issued after a day of talks.
"There is a resolve that this crisis will be resolved, that no tools will be spared to address this issue," Egypt's finance minister, Youseff Boutros Ghali, chairman of the IMF's policy panel, told a news conference late Saturday.
In his Rose Garden appearance, Bush made a plea for nations work together to address the crisis, avoiding the go-it-alone protectionist trade strategies that worsened conditions during the Great Depression.
"In an interconnected world, no nation will gain by driving down the fortunes of another. We are in this together. We will come through it together," Bush said. "There have been moments of crisis in the past when powerful nations turned their energies against each other or sought to wall themselves off from the world. This time is different."
White House spokesman Tony Fratto said Bush's commitment to collaborative action was repeated and agreed to by every official and minister who took part in a private White House meeting before the statement. Participating in that session with the president were top officials from the Group of Seven powers -- the United States, Japan, Germany, France, Britain, Italy and Canada -- as well as from the European Union, World Bank and International Monetary Fund.
Bush did not mention any specific action that prompted his call. But Ireland recently moved to guarantee all bank deposits, triggering similar actions in Germany and other countries concerned that nervous depositors would move their bank accounts to Ireland.
In his White House remarks, the president barely referenced a significant new step from his administration -- partial nationalization of some banks. After days of speculation this move was coming, Treasury Secretary Henry Paulson announced late Friday night that the government would buy part ownership in an array of American banks.
President Hoover tried something like that in 1932 during the Great Depression. No detail was provided about how the new approach would work, only that it was similar to Britain's move to pour cash into its troubled banks in exchange for stakes in them. The U.S. government would use an unspecified portion of the $700 billion approved by Congress a week ago to purchase stocks in a wide variety of banks and other financial institutions.
The rescue program originally was sold to Congress and the public as a plan to buy mortgage-related loans from financial institutions. The goal was to remove troubled assets from those institutions' books and inspire them to restart more normal lending operations.
Congress passed the massive and hard-fought legislation, and Bush signed it. The government raised the amount of bank deposits it insured. Billions of dollars of reserves have gone into banking systems in the U.S. and other countries. Yet credit, the economy's lifeblood, has remained virtually frozen.
This paralysis in the credit markets has translated into intense turmoil in the stock markets. The Dow Jones industrial average just completed its worst week in history, plummeting more than 18 percent. Over the past year, people in the U.S. have watched $8.4 trillion drain from investment accounts and retirement savings.
So the administration decided to use the bailout bill to pump equity directly into the banks -- an idea never mentioned during the congressional debate. The administration says it is authorized in an obscure corner of the 400-page legislation.
Officials are not saying how long it will take to get this program under way -- just as is the case with the even more complicated effort to buy mortgage-backed securities.
Bush seemed to acknowledge that the lag is feeding anxiety on Wall Street. "These extraordinary efforts are being implemented as quickly and as effectively as possible," Bush said. "The benefits will not be realized overnight."
The White House session with Bush followed a three-hour meeting Friday night of G-7 finance ministers. The president largely echoed their terse statement, saying the nations have pledged to "do what it takes to resolve this crisis."
Among their promises are preventing the failure of major banks, unfreezing credit markets, bolstering deposit insurance programs, getting the battered mortgage financing system to operate more normally and working with poorer but fast-growing nations that also are feeling the pinch.
Officials in Europe prepared for a meeting Sunday of the leaders of the 15 nations using the euro currency. German Chancellor Angela Merkel and French President Nicolas Sarkozy said Saturday they opposed to the creation of a common financial rescue fund for Europe.
For Bush, it was the 22nd day in the past 27 he had spoken about the financial crisis, since evidence first arose that the year-old subprime mortgage mess was evolving into a broader and more calamitous meltdown.
Bush also addressed the crisis in his weekly radio address, as did Democratic vice presidential candidate Joe Biden in delivering his party's response. Democratic presidential candidate Barack Obama, in a series of Philadelphia rallies, also focused on words of calm.
"I know these are difficult times. I know folks are worried," he said. "But I also know that now is not the time for fear or panic. Now is the time for resolve and steady leadership. Because I know we can steer ourselves out of this crisis."
