I gave a lecture at the London School of Economics on the structural changes in the global financial system and how they shed light on recent events

Some highlights: The GFC was a watershed event that set in motion two related structural changes to the global financial system. Those changes define the state of the system today

Inspired by the debate between @nfergus and @adam_tooze on the current state of globalisation, I devoted my lecture at Columbia this week to take the pulse on global value chains:

"Global value chains under the shadow of Covid"

bis.org/speeches/sp230… First, some background to set the scene

Real exports have grown but so has real GDP; we need to scale trade by the size of the economy, taking account of the different price indices (exports are goods heavy, GDP is services heavy as @BaldwinRE has argued eloquently)

"There is a bitter irony in the turmoil currently gripping the crypto universe..."

My op-ed in the FT on the great unravelling of crypto

ft.com/content/76234c… While we survey the wreckage and plot a course for the policy response to rein in the sector, we need to keep in mind some home truths

Crypto operates under the banner of decentralisation, but it is highly centralised in two crucial respects

Will commodity prices tip the global economy into a 1970s-style stagflation?

Today's #BIS_Bulletin weighs the arguments and does some number crunching in search of an answer

A thread:
bis.org/publ/bisbull54… Price rises have affected a broader range of commodities this time round than in the 1970s (for instance, see the yellow bar on industrial metals), but the size of the oil price shock has been much less than the 1973 shock

Central banks are picking up the pace in their work on digital currencies, moving from talk to actions

On 9-10 February, I chaired a meeting of deputy governors from 26 EM central banks

Here is a thread on the key lessons, just published

bis.org/publ/bppdf/bis… In the run-up to the meeting, Mexico and India had announced their intention to launch their CBDCs and set the tone toward practical design choices

Here's a summary table from the report; numbers indicating extent of buy-in (1.0 means unanimity) Image

Crypto markets have found an outlet in centralized finance, or "DeFi"

Is DeFi the acceptable face of crypto?

Or can central bank digital currencies (CBDCs) do DeFi but without selling coins for speculation?

A thread on a panel I chaired this morning Image One notable development has been the fragmentation of the blockchain universe, with #Ethereum giving up its dominance to newer chains

The chart below shows the percentage of collateral value locked in various chains; #Ethereum had close to 100%; now barely 50% Image

House prices boomed during the Covid recession - a big departure from past recessions

Where house prices go from here will be a key determinant of global activity

A thread from our latest #BIS_Bulletin on the topic

bis.org/publ/bisbull50… First, it's worth stressing how unusual the Covid recession was in terms of house prices

Typically, economic downturns are followed by a moderate fall in house prices lasting about four quarters

This time round, there was not even a temporary dip

The financial channel of exchange rates operates through the risk capacity of market participants and shows up in the response of financial conditions to exchange rate movements

This new BIS Working Paper shows that the channel operates for stock returns, too

A thread: First finding:

Dollar-denominated returns tend to be an amplified version of the local currency-denominated returns; both the gains and losses are magnified when converted into dollar returns

Hence the "dollar return multiplier"

The opening seminar for the Indonesian G20 presidency was a good opportunity to take stock of #bottlenecks and #inflation risks

A thread follows

bis.org/speeches/sp211… Supply bottlenecks have grabbed all the headlines recently, but longer-term structural changes brought about by the pandemic (labour markets, especially) are important to understand where we are headed

Good observations by @EtraAlex

Two further points to bear in mind are (1) counterparty sector (official or private financial, private non-financial) and (2) the distinction between location and nationality

For this, the following BIS data would shed more light

(continued) First, regarding the counterparty sector, the 2020:Q1 surge in cross-border banking flows stands out

Normally, we would expect a sharp retrenchment during stress episodes, but there was instead a surge, as discussed in this #BIS_Bulletin

Thanks to colleagues at LBS for the opportunity to take stock of the decentralisation agenda in digital finance, from #bitcoin to #DeFi

A thread on the key points:

bis.org/speeches/sp211… Blockchain has breathed new life into the idea of money as a substitute for a ledger that keeps score of who owes what to whom

"Money is memory" according to the classic 1998 by Narayana Kocherlakota

The inflation surge has brought #bottlenecks under the spotlight

Today's #BIS_Bulletin takes a closer look at what's going on and what we might encounter going forward

A short thread follows
bis.org/publ/bisbull48… Bottlenecks started out as disruptions to supply, but they have morphed into something more

Key point to bear in mind: in aggregate at least, supply has caught up to pre-pandemic levels in key sectors like semi-conductors as well as in raw materials and shipping

It was a pleasure to moderate this panel on scaling up #blockchains

The session starts at 5:28:50 on the video link below

Here's a short thread on my key takeaways: Decentralization is motivated by the governance benefits - the idea is that the checks and balances of the community as a whole is the best way to safeguard the integrity of the system and avoid capture by a few powerful entities

Timely outing on Odd Lots with @tracyalloway and @TheStalwart to discuss data silos and "walled gardens" in the digital economy

One thought occurred to me after the podcast.

Here's a quick thread. Privacy looms large when CBDCs come up, as digital currencies rely on a ledger of some kind - a record of who owns what, when, and who pays what to whom; see this (tough but fair) interview with @izakaminska and @senoj_erialc I gave to @FTAlphaville

Corporate credit markets decoupled in March; bond issuance boomed but discretionary bank credit stalled

Unequal access to credit between large firms and the rest is the topic of today's #BIS_Bulletin

A thread follows

bis.org/publ/bisbull29… First, some facts:

The weekly series on new borrowing in debt markets surged at the end of March (left panel); but most of the surge came from bond issuance (middle panel) rather than from syndicated loans
