US inflation data released on Tuesday
US Consumer Price Index (CPI) data for the month of August is scheduled for release on Tuesday.
Analysts have forecast prices moderating as travel and fuel costs fall. Analysts surveyed by Dow Jones expect headline CPI to have declined by 0.1% for all items in the month of August.
If this is the outcome, the global cryptocurrency market cap could increase above its current value of $1.1tn due to the anticipation of less hawkish moves on monetary policy by the Federal Reserve.
If headline inflation reduces, after a flat reading in July, the cryptocurrency market could react again with a rally.
The CPI report is seen as a key guiding factor for next week’s Federal Reserve rate decision and could influence the Fed to become less aggressive with their restrictive monetary policy of subsequent interest rate hikes.
The long-term expectation is that the Fed’s terminal rate could reach 4% by the end of the year inching higher over the coming months.
Michael Saylor's Microstrategy bitcoin buy
MicroStrategy (MSTR), a US-based company that provides business intelligence, mobile software, and cloud-based services, has filed with the US Securities and Exchange Commission (SEC) to sell up to $500m of stock to fund bitcoin purchases.
The move shows that MicroStrategy's executive chairman Michael Saylor isn't slacking on his conviction to turn his software development company into one of the world's major bitcoin holders.
Bitcoin pioneer Max Keiser tweeted in June that MicroStrategy has board clearance to make a $500m bitcoin buy.
Keiser added that Saylor is currently “chilling on his yacht” and will make a decision on whether to go ahead soon.
The deal was confirmed when the details of the SEC filing became public on Friday.
The shares will be sold through Cowen & Co and BTIG LLC, according to the filing, though no date was provided for any potential sales.
However, the firm added that it intends to retain all future earnings to purchase additional bitcoin and for the development of the software business.
