INTRODUCTION

The LendZen Index tracks the price of mortgage rates across a spectrum of mortgage-backed securities.

Each chart starts at $0 for the first date 🔵 of the time series and measures the rate of change in dollar terms per $100K of loan amount.

The most expensive point in the series is marked with a red 🔴 dot, and the least expensive with a green 🟢 dot.

The measurements in the key box show the total change in price between each colored dot on the index, including high-to-low for descending charts and low-to-high for ascending charts.

This publication is focused on the index data only. If you want to dive deeper into the events influencing markets and mortgage rates, then visit my Weekly Kut Substack.

LendZen provides a fully automated mortgage shopping experience that gives you anonymous access to all mortgage rates with full transparency of costs upfront.

The below snapshot is just a glimpse of today’s rates, but the pricing you see is exactly what you get - there are no additional lender fees or origination charges.

MORTGAGE RATE INDEX

The 5-Day change in price is -54 basis points (bps).

The last 24-hour change is -18 bps.

Since September 29, the price of mortgage rates decreased 32 basis points, as seen in the 10-Day chart below.

During the last 30 days (🔵 to 🟡) mortgages have increased in price by 281 basis points.

The 30-Day chart is useful for spotting trends, plus it gives value to them.

For example, the change in price from the low 🟢 to the high 🔴 was 358 basis points.

This was a change of $17900 on a $500,000 mortgage.

Over the past year mortgage rates are now 535 bps more expensive.

The lowest price was February 27, and the highest price was  October 5.

INDEX METHODOLOGIES

Most mortgages are sold into mortgage-backed securities (MBS). The price of these bonds determines rates for all banks and lenders.

However, mortgage rates DO NOT rise or fall.

The full range of rates is always available, and instead the price of each rate is what changes.

For example, when mortgage bond prices fall the fee for each rate increases. The same rates exist, but now each is more expensive.

Traditional mortgage indices falsely suggest rates are changing by posting a daily “average” they conjure up from unverifiable data.

Meanwhile, the LendZen Index tracks the price of each mortgage rate across a spectrum of publicly traded MBS.

This provides a clearer picture of how the cost to obtain a mortgage has changed, regardless of the lender, rate, or borrower credit score.

LENDZEN MORTGAGE TREASURY SPREAD

Tracking the “spread” between mortgages and treasury bonds can provide useful perspectives, but only if measured accurately.

There are unique dynamics of mortgage-backed securities, such as prepayment speeds, that are overlooked by the “average rate” indexes.

However, these variables heavily influence how investors allocate to mortgage bonds, and a spread that is calculated without this information has critical flaws that make it unreliable.

The LendZen Mortgage Treasury Spread (LMTS) uses actual bond yields to create a historically consistent and reliable data set.

OCT 13  =  1.09           24h  =  -2 bps 

12m Avg  =  0.98       YoY  =   2 bps

Tracking the “spread” between mortgages and treasury bonds can provide useful perspectives, but only if measured accurately.

There are unique dynamics of mortgage-backed securities, such as prepayment speeds, that are overlooked by the “average rate” indexes.

However, these variables heavily influence how investors allocate to mortgage bonds, and a spread that is calculated without this information has critical flaws that make it unreliable.

The LendZen Mortgage Treasury Spread (LMTS) uses actual bond yields to create a historically consistent and reliable data set.

OCT 2  =  1.06           24h  =  -3 bps 

12m Avg  =  0.98       YoY  =   0 bps

INTRODUCTION

The LendZen Index tracks the price of mortgage rates across a spectrum of mortgage-backed securities.

Each chart starts at $0 for the first date 🔵 of the time series and measures the rate of change in dollar terms per $100K of loan amount.

The most expensive point in the series is marked with a red 🔴 dot, and the least expensive with a green 🟢 dot.

The measurements in the key box show the total change in price between each colored dot on the index, including high-to-low for descending charts and low-to-high for ascending charts.

This publication is focused on the index data only. If you want to dive deeper into the events influencing markets and mortgage rates, then visit my Weekly Kut Substack.

The below snapshot is just a glimpse of today’s rates, but the pricing you see is exactly what you get - there are no additional lender fees or origination charges.

MORTGAGE RATE INDEX

The 5-Day change in price is +47 basis points (bps).

The last 24-hour change is -37 bps.

Since September 18, the price of mortgage rates increased 166 basis points, as seen in the 10-Day chart below.

During the last 30 days (🔵 to 🟡) mortgages have increased in price by 370 basis points.

The 30-Day chart is useful for spotting trends, plus it gives value to them.

For example, the change in price from the low 🟢 to the high 🔴 was 407 basis points.

This was a change of $20350 on a $500,000 mortgage.

Over the past year mortgage rates are now 522 bps more expensive.

The lowest price was February 27, and the highest price was  September 30.

INDEX METHODOLOGIES

Most mortgages are sold into mortgage-backed securities (MBS). The price of these bonds determines rates for all banks and lenders.

However, mortgage rates DO NOT rise or fall.

The full range of rates is always available, and instead the price of each rate is what changes.

For example, when mortgage bond prices fall the fee for each rate increases. The same rates exist, but now each is more expensive.

Traditional mortgage indices falsely suggest rates are changing by posting a daily “average” they conjure up from unverifiable data.

Meanwhile, the LendZen Index tracks the price of each mortgage rate across a spectrum of publicly traded MBS.

This provides a clearer picture of how the cost to obtain a mortgage has changed, regardless of the lender, rate, or borrower credit score.

Since September 10, the price of mortgage rates increased 124 basis points, as seen in the 10-Day chart below.

During the last 30 days (🔵 to 🟡) mortgages have increased in price by 303 basis points.

The 30-Day chart is useful for spotting trends, plus it gives value to them.

For example, the change in price from the low 🟢 to the high 🔴 was 310 basis points.

This was a change of $15500 on a $500,000 mortgage.

Over the past year mortgage rates are now 439 bps more expensive.

The lowest price was February 27, and the highest price is  September 23.

INDEX METHODOLOGIES

Most mortgages are sold into mortgage-backed securities (MBS). The price of these bonds determines rates for all banks and lenders.

However, mortgage rates DO NOT rise or fall.

The full range of rates is always available, and instead the price of each rate is what changes.

For example, when mortgage bond prices fall the fee for each rate increases. The same rates exist, but now each is more expensive.

Traditional mortgage indices falsely suggest rates are changing by posting a daily “average” they conjure up from unverifiable data.

Meanwhile, the LendZen Index tracks the price of each mortgage rate across a spectrum of publicly traded MBS.

This provides a clearer picture of how the cost to obtain a mortgage has changed, regardless of the lender, rate, or borrower credit score.

LENDZEN MORTGAGE TREASURY SPREAD

Tracking the “spread” between mortgages and treasury bonds can provide useful perspectives, but only if measured accurately.

There are unique dynamics of mortgage-backed securities, such as prepayment speeds, that are overlooked by the “average rate” indexes.

However, these variables heavily influence how investors allocate to mortgage bonds, and a spread that is calculated without this information has critical flaws that make it unreliable.

The LendZen Mortgage Treasury Spread (LMTS) uses actual bond yields to create a historically consistent and reliable data set.

SEP 23  =  1.10           24h  =  3 bps 

12m Avg  =  0.98       YoY  =   1 bps

INTRODUCTION

The LendZen Index tracks the price of mortgage rates across a spectrum of mortgage-backed securities.

Each chart starts at $0 for the first date 🔵 of the time series and measures the rate of change in dollar terms per $100K of loan amount.

The most expensive point in the series is marked with a red 🔴 dot, and the least expensive with a green 🟢 dot.

The measurements in the key box show the total change in price between each colored dot on the index, including high-to-low for descending charts and low-to-high for ascending charts.

This publication is focused on the index data only. If you want to dive deeper into the events influencing markets and mortgage rates, then visit my Weekly Kut Substack.
