the way I do it is by quoting the logically connected post, thus forming a chain of related posts if you build a DAG with temporal order & display posts from oldest to newest you get a thread of posts, forming a small article

so everything that I post on other social media, like X/Twitter also gets posted to my microblog at https://illya.sh/thoughts/ frequently an idea evolves into a series of posts - a thread/small article

Bitcoin is still in a weekly uptrend it must either go up or down to โ‰ˆ$109500 - a strong weekly support two factors in play here: 1๏ธโƒฃ USD index - inverse correlation 2๏ธโƒฃ Global liquidity- correlation keep watching central bank's open market operations & balance sheets

๐Ÿš€ gold approaching $3400. $3300 was a good price for longs - like I wrote a week ago currently gold is one of the only assets where leverage entails a much lesser risk upside price pressure is coming from several points

gold price is back up to its price 2 weeks ago so it indeed was a good idea to long it at the pullback

5 days ago I wrote that USD/RUB rate will fall. 5 days later it's down โ‰ˆ2% despite oil being down - gold is up Ruble has hedge from multiple sides

if you've read my previous posts you know that gold is โ‰ˆ36% of Russia's international reserves this is taken straight from the Bank of Russia's balance sheet statement 100% of it is stored in Russia, thus no counterparty risk critical component of Ruble's strength

๐Ÿ‡จ๐Ÿ‡ณ China's gold holdings are at their highest level in 43 years gold is now 6% of PBoC international reserves. but that's still below the world average of โ‰ˆ14%. expect that gap to continue to shorten further see my drawings on this nice chart spanning over 47 years i found

central banks will continue to buy gold you'll be able to confirm that in their upcoming balance sheets reports. pay special attention to China & Russia enjoy the dip, because smart money is!

China sold US treasuries and bought gold - just like I wrote over 3 months ago gold now accounts for โ‰ˆ6% of PBoC international reserves, while US treasury holdings are โ‰ˆ40% from their peak in 2013 off-ramp from USD debt to alternative assets continues its progress

๐Ÿ‡จ๐Ÿ‡ณChina has been increasing their gold reserves YTD Gold price keeps going up - major central banks continue to load up Gold is a hedge against USD. Tariffs are a medium of USD weaponization ๐Ÿ‘‰ Expect US securities sell-off for gold by People's Bank of China

the 70% USD dominance here is as calculated by the Fed across the chosen 5 chosen buckets - with the end result being a weighted composite measure so don't read this as a literal 70% of all cross-border transactions

๐Ÿ‡บ๐Ÿ‡ธ USD dominance is alluring, accounting for โ‰ˆ70% of currency usage worldwide even countries that do relatively little trade with US have most of their transactions done in US dollars ex: ๐Ÿ‡ฎ๐Ÿ‡ณ India invoices 86% of its exports in USD, while only 15% of its exports being to US

legally mortgage backed securities are bonds since they are tradable debt securities but they're not a plain bond, due to the option of borrower's early repayment Macaulay or modified duration used for Treasuries doesn't work - you need effective/option-adjusted duration

the duration formula for MBS assumes for some pre-payments if those happen at a smaller rate - the duration increases

raising yields means lower incentives to re-finance mortgages which reduces the amount of pre-payments thus, the duration increases when yields are raising - so even a higher price decrease

optionality/convexity premium in mortgage backed securities is interesting when market yields fall the price should rise, but since borrowers take advantage of lower mortgage rates to make early payments - the price does not raise as much, due to lowered duration

Fed's balance sheet expansion with agency MBS reduced risks in liquidity, market depth and optionality/convexity this is a crucial point to understand - it wasn't just the Fed buying agency MBS, but the explicit government guarantee that accompanied it thus, the yields fell

Ginnie & Fannie Mae conservatorship in Sept 2008 made agency MBS default risk free essentially, the US Treasury covers all losses from GNMA and FNMA up to $200 billion each from the total $400B budget โ‰ˆ$170B are still available once exhausted it will surely be increased

to lower the mortgage rates the Fed can purchase agency MBS - likely they did in QE 1 2008 buying mortgage backed securities raises their price and provides liquidity for dealers. this directly pushes down the yields expect some MBS QE to come in the near future

๐Ÿ‡บ๐Ÿ‡ธ๐Ÿ‡ท๐Ÿ‡บ USD/RUB rate already fell to July 24th close, below 80 although it's also important to note that there are several factors at play - USD index is also down today despite oil down - gold is up. this is about the monetary policy of Russia and their balance sheet structure

๐Ÿ‡ท๐Ÿ‡บ oil up is GOOD news for Russia & Ruble every surplus above $60/barrel of Urals oil increases FX reserves in NWF (Yuan or gold) - an interplay between MoF and CBR exporters pay taxes in Ruble - so higher buying pressure mark my words: ๐Ÿ‘‰ you'll see USD/RUB exchange rate fall

together, ON RRP, IORB, Discount Rate and SRF create a corridor for rates, which stay within the target 4.25%-4.50% ๐Ÿ‘‰ by "firms" i mean select non-bank financial institutions - think dealers, market makers & other wholesale debt institutions

so how does the FED currently targets an interest rate range between 4.25%-4.50%? let's consolidate everything with an example using current, real-world data
