The Federal Reserve keeps interest rates unchanged and reiterates its dovish policy position.

After a two-day meeting, the fed announced on Wednesday afternoon that it would leave interest rates unchanged at 0 per cent and 0.25 per cent and the excess reserve ratio (IOER) at 0.1 per cent.

The Fed statement showed that members unanimously agreed to the interest rate decision (in line with the last meeting). The Fed also decided to leave the discount rate unchanged at 0.25% and extend the central bank's repo and swap lines until March 31 next year.

Interest rates will remain at current levels until the Fed is convinced that the economy has weathered the recent crisis and is on track to achieve its goal of maximum employment and price stability, the Fed statement said. The path of economic development depends on the development of the coronavirus epidemic. Economic activity and jobs rose, but still below previous levels. The Fed will use all its tools to support the economy.

Weak demand and low oil prices have kept inflation low, and the Fed will increase its asset size (asset purchases) "at the current rate," the statement said. Financial conditions have improved, in part because of the Fed's actions.

In its statement, the Fed reiterated that the ongoing health crisis will be a drag on economic activity, employment and inflation.

Media commented that the Fed resolution to maintain stability policy measures remain unchanged, the wording of the resolution is regular, referring to the risk of the epidemic, but also stressed the current situation that the level of economic activity has begun to stabilize, and the wording is less relaxed than expected.

Some analysts said that there was no bright spot in the wording of the Fed's resolution, the ball was kicked back to fiscal policy, and the dollar continued to be under pressure.

The policy decision issued by the Federal Reserve on Wednesday (July 29) local time is little changed compared with the previous one. While continuing to maintain stability, it still emphasizes the impact of the epidemic, but also stresses that the previous measures have already had an effect. Further policy direction in the future will still be based on the development of the epidemic, so bond purchases will remain at the current level.

Although the Fed did not disclose drastic expectations of further easing, investors saw its language as largely emphasizing that they had done their best, kicking the ball of responsibility back into the area of fiscal policy. At the same time, the news on another battlefield is that the two parties in Congress are still deadlocked in negotiations on a further fiscal stimulus package, which is the real culprit that has added to the pressure on the dollar index in recent days.

After the announcement of the Fed statement, the CME Fed Watch predicted that the probability of the Fed keeping interest rates in the 0.5% range in September is 100%, and the probability of raising interest rates by 25 basis points to 0.25% is 0%. In November, the probability of keeping interest rates in the 0.25% range is 100%, and the probability of raising interest rates by 25 basis points is 0%.

Powell continues to stress the impact of the epidemic, saying fiscal policy is needed to support recovery

Powell, chairman of the Federal Reserve, said at a news conference after the announcement of the Fed's decision that the Fed's goal is to ensure a strong economic recovery and control the destructive power of the epidemic. "all of us have a role to play in dealing with the epidemic," he said.

Household spending has recovered by half and corporate fixed asset investment has yet to recover, says Mr Powell. The second quarter's GDP contraction is likely to be the biggest ever. The Fed will do everything it can to help the economy grow.

He believes that the epidemic has a significant impact on inflation, and rising food prices have increased the burden on the public. Falling wages suggest that the labour market still has a long way to go to recover. The number of confirmed cases of coronavirus has increased significantly, the epidemic has left a significant imprint on inflation, and the path of economic development is extremely uncertain.

Powell says a full recovery is unlikely until people feel safe. The economic path depends on the actions of the government at all levels. He said he saw signs of an increase in cases putting pressure on the economy. The economic path depends on the level of government action.

Some measures of consumer spending have fallen since the end of June, and lending programmes have boosted the expansion of private credit, he said. Powell reiterated that the Fed can only lend, not allocate funds. Fiscal policy has had a significant impact so far. Maintaining credit flows is crucial to economic recovery.

Powell stressed the need for fiscal and monetary policies to support the recovery. It is planned to end the framework review that will be postponed due to the epidemic.

Analysts said that Federal Reserve Chairman Powell's speech at the press conference was pessimistic, continued to emphasize the impact of the epidemic, and also shifted the responsibility for further boosting the economy to fiscal policy, which further undermined confidence in the dollar bulls.

The market pays attention to the congressional testimony of the executives of the tech giants.

On Wednesday, Amazon.Com Inc (AMZN) CEO Jeff Bezos, Apple Inc (AAPL) CEO Tim Cook, Facebook Inc (FB) CEO Mark Zuckerberg and Alphabet (GOOG, GOOGL) CEO Sunda Pichai and others attended a hearing of the U.S. House of Representatives Judiciary Committee to discuss a series of worrying market forces and business practices of these companies. Some of these issues have been carefully examined by the relevant authorities for antitrust purposes.

Tim Cook of Apple Inc said in testimony to the House Judiciary Committee on Wednesday that Apple Inc is not a monopoly. And iPhone does not occupy a dominant position in smartphones, in fact, Alphabet Inc-CL C has the world's dominant operating system, that is, Android.

Cook attributed it to Apple Inc to inspire and develop the huge mobile software market, and even quoted the company's founder Steve Jobs as "It Just Works" to describe its products.

Us President Donald Trump tweeted on Wednesday: "if Congress does not uphold justice on the issue of big technology companies, then I will do so by issuing an executive order." "

In prepared testimony released on Tuesday night, all four CEO argued that their entrepreneurial spirit embodies American values, that their companies face fierce competition and that they are always innovating to create better products for consumers.

Many believe that the coronavirus pandemic exacerbates these problems as it wipes out the giants' competitors and pushes business further to already powerful technology companies.

WedBush analyst Dan Ives said in the research paper: "although fundamentally speaking, the FAANG Big five have performed better in the difficult environment than many people feared, especially Amazon.Com Inc, the company is obviously the beneficiary of the current epidemic blockade and quarantine measures, but looking ahead to 2020, the storm of antitrust investigation against these TIA giants seems to be coming from Washington. "

He added: "We note that many state investigations have focused on Google's online advertising, while the Justice Department has focused more broadly on concerns that Google is using its search dominance to stifle competition. Apple Inc App Store's imposition of a 30 per cent handling fee is the focus of firepower in both the US and Europe, especially in the EU. With Cook attending the hearing, Apple Inc's business behavior will be subject to more in-depth investigation. "

Us Congress continues to hold new round of fiscal stimulus negotiations

On Wednesday, the House Judiciary Committee was negotiating a new economic stimulus package to support workers and small businesses.

Lawmakers continued negotiations on a new stimulus package that would provide Americans with another round of checks for $1200 after Senate Majority Leader Mitch McConnell unveiled a new $1,000bn plan. However, additional federal unemployment benefits could be cut from the current $600 a week to $200 a week.

While the future of monetary policy and technology regulation will be the focus today, new fiscal stimulus measures will be most important in setting the short-term trajectory for the nascent economic recovery.

Notably, Powell and his colleagues also urged Congress to do more, and they may be more inclined to exert pressure to wait for them to act. Democrats clashed with Republicans, who fought internally over the expansion of emergency aid. The most pressing issue is the federal unemployment benefit, which expires at the end of this month.
